The Conical centrifuge baskets as the key component of the centrifugal sieves When working, the Conical centrifuge basket not only has to withstand vibration loads during high-speed rotation, but also has to withstand severe impact from coal and water, so the strength and precision requirements are relatively high.     The Conical centrifuge baskets are mainly composed of an upper flange, a lower flange, a strength ring and a stainless steel conical mesh cylinder. The stainless steel conical mesh cylinder is welded by several fan-shaped screens, and the fan-shaped screen is formed by rolling stainless steel wire into wedge-shaped screen bars and support bars through special equipment. The screen bars are arranged along the cone generatrix of the screen basket. In order to reduce the blockage of the screen seam, the screen seam needs to be made into a wedge shape.   The screen slot is generally 0.3-1mm, and can also be determined according to user requirements. The Conical centrifuge basket is connected to the main machine with bolts through the holes on the upper flange or lower flange. The screen bars and support bars are wear-resistant non-magnetic stainless steel. Generally, their service life is 3-4 months. At present, our Conical centrifuge baskets are widely used in mining, coal, petroleum, fertilizer, food, environmental protection and other industries.  Main advantages: It can be applied to most existing centrifuges, with narrow slit aperture, high mechanical strength and excellent corrosion resistance, low maintenance frequency and cost.

Starch is widely used in food and industry, and its quality and output are of great concern. How can we solve the problems of unstable starch quality, many impurities and low purity? In this article, Huatao Group will provide the perfect answer to your question. Reasons for low production efficiency and unstable quality of starch: 1. Manual dominance Using traditional technology, traditional sweet potato starch production is mainly manual operation. Simple mechanical tools may be used in some links, but it relies on manpower as a whole.   2. Unstable product quality There are many problems in the filtering, precipitation and drying links. The crushed sweet potato pulp is initially separated by manual filtration or simple filter screen to remove larger residues. This has a poor filtering effect and it is difficult to remove tiny impurities, making the extracted starch low in purity, the filtration speed is slow, and it takes a long time. The quality of filtration is easily affected by the operator, resulting in large differences in the quality of starch in different batches.Some impurities, such as fiber and butter, often remain in the starch, resulting in low starch purity.   Solution: Adopting Huatao Technology 1. Using modern mechanical equipment and automatic control systems, fully automated production is achieved from the cleaning, crushing and separation of sweet potatoes to the drying and packaging of starch. This greatly reduces labor intensity, improves production efficiency, and also reduces the impact of human factors on product quality. 2. The new process adopts advanced technologies such as multi-stage centrifugal separator and cyclone separation. Huatao Centrisieves can more thoroughly separate starch from impurities such as fiber and butter, thereby improving the purity of starch. The sweet potato starch produced is white in color, uniform in particles, and its appearance quality is significantly better than that of traditional process products.   Quick link of Related Product: Centrifugal Sieve www.huataofilter.com/compressor-rotor/67629185.html    Conical Centrifuge Baskets www.huataofilter.com/pressure-screen-basket-cylinder/67922551.html

Common fault analysis of the leakage and startup of the fully automatic self-cleaning filter:   1. There are two basic reasons for the leakage problem of the transmission shaft part of the self-cleaning filter (the leakage of the cylinder and flange part is not within this range), as follows:   1)The material or specification of the transmission shaft sealing ring does not meet the requirements, and the sealing ring that meets the requirements is replaced.   2)The second is that the sealing ring is worn during long-term operation, causing the sealing between the transmission shaft and the filter body to be loose and leaking. In this case, timely replacement of the sealing ring of the corresponding specifications can solve these problems.   2. Automatic sewage valve failure   Specifically, the sewage valve does not move during automatic cleaning or the sewage valve cannot be opened or closed.   1)When this problem occurs, the electromagnetic sewage valve is generally selected. The electromagnetic valve is a pilot type. The electromagnetic iron first opens the pilot hole, and then relies on the pressure of the water in the system to flush the diaphragm to open the valve.   2)Since there are many impurities in the sewage, it is easy to block the pilot hole, resulting in the electromagnetic valve not moving after opening or not closing tightly.   3)Use electric ball valve or hydraulic solenoid valve as drain valve to solve the problem that ordinary solenoid valve is easy to fail as the automatic drain valve of self-cleaning filter.   3. Self-cleaning control system failure   Frequent startup leads to an increase in the amount of cleaning water, shortening the service life of the filter.   1)This problem is generally caused by the parameter setting of the filter not meeting the working conditions.   2)This is mainly the problem of the cleaning pressure difference value and cleaning time interval set by the pressure difference controller. The filter cleaning system is frequently started and the control system problem can be solved by setting a large pressure difference value and time interval.   Related Products: External Scraper Self-cleaning Filter,Basket Filter,Bag Filter ,Automatic Back Flushing Filter,Automatic Filter,Automatic Back Wash Cleaning Filter,etc    

I. Installation Steps   1. Thoroughly clean the filter housing. 2. The inlet and outlet of the housing are connected to the pipeline of the filtration system. Pay attention to the direction when connecting to ensure that the filter element is in the state of water inlet from the outside and water outlet from the inside. 3. Open the plastic bag at one end of the filter element opening and check whether the O-ring is intact and in place.   4. Wet the O-ring and the filter element seat jack with a suitable wetting agent (such as water). 5. Hold the end of the filter element close to the O-ring and vertically insert the filter element socket into the filter element seat jack. 6. After all the filter elements are inserted, remove the filter element packaging bag, then buckle the pressure plate to fix it, and then install the upper head. 7. Open the bleed valve on the top of the housing.   Regarding  Filters  Liquid Filtration,Precision Filter,Precision Security Filters,Automatic Filter,Scraper Self-cleaning Filter, Multi Media Filter,Quartz Sand Filter,Ultra Precision Filter,Cartridge Filter And Parts.   8. Slightly open the inlet valve to allow liquid to enter the housing until the liquid overflows from the bleed valve on the top of the housing. At this time, close the bleed valve. 9. Slowly adjust and open the downstream outlet valve until it is fully opened. 10. Slowly adjust and open the inlet valve until it is fully opened. At this time, the pressure drop between the upstream and downstream of the filter is 0.02Mpa (determine the initial pressure drop under the flow rate).   II.Precautions for Use   1. Prevent pressure shock during operation and prohibit reverse pressurization. 2. When the pressure drop between the upstream and downstream of the filter is greater than 0.3Mpa or the flow rate drops significantly, consider replacing the filter element.   3. If the filter is not working temporarily, do not dry the filter element, but soak it in a suitable sterilization solution (or inject such a solution into the shell), and rinse the sterilization solution before reuse.   4. If the filter is steam sterilized, the condensed water in the steam pipeline must be drained first, and the steam pressure should not exceed 0.1Mpa. At the same time, the pressure drop between the upstream and downstream of the filter should not exceed 0.015Mpa. If the wet filter element is steam sterilized, the liquid absorbed by the filter element should be drained with clean compressed air before passing the steam, otherwise the filter element will be damaged when the steam is passed.    

After one year of normal production, multi-media filters should be inspected regularly to ensure safe operation without accidents within the second year. In order to shorten the downtime of regular inspections, if the number of inspectors and maintenance workers permits, it should be carried out at the same time as the inspection of other equipment and devices in the water station. If any abnormality is found during the inspection, it must be handled in time and resolved.   1. Filler inspection   Inspect the quartz sand filter material. If the quartz sand is seriously contaminated, it should be replaced completely.   2. Internal fastener inspection   Check the bolts, nuts and other fasteners in the filter. If they are loose, tighten them again.   3. Internal cleaning   After flushing with water, clean the inside of the filter with a waste cloth strip.   4. Refill the filter material   Refill the filter material according to the specified quantity and requirements, measure whether the filling amount reaches the required amount, and replenish the insufficient part (generally, the filter material of quartz sand and activated carbon mixed needs to be replaced once a year, depending on the water quality.)   5. Manhole sealing gasket inspection   Check whether the manhole sealing gasket is deformed. If deformed, it should be replaced. Soak the bolts and nuts in cleaning oil to thoroughly remove rust; apply butter to the bolts and nuts when installing the manhole cover.   Related Filters for Liquid Filtration,Multi Media Filter,Quartz Sand Filter,Automatic Filter,Scraper Self-cleaning Filter,,Ultra Precision Filter,Cartridge Filter And Parts.

1. The core part of the precision filter is the filter element, which is made of special materials and is a wearable part that requires special protection;   2. After the precision filter has been working for a period of time, the filter element will intercept a certain amount of impurities. At this time, the pressure drop will increase and the flow rate will decrease. It is necessary to remove the impurities in the filter in time and clean the filter element at the same time;   3. When removing impurities, pay special attention to the precision filter element, which must not be deformed or damaged. Otherwise, the purity of the medium after the filter element is installed will not meet the design requirements;   4. Some precision filter elements cannot be used repeatedly, such as bag filter elements, polypropylene filter elements, etc.;   5. If the filter element is found to be deformed or damaged, it must be replaced immediately.   Precautions for coarse filter:   1. The core part of the filter is the filter core. The filter core is composed of a filter frame and a stainless steel wire mesh. The stainless steel wire mesh is a consumable part and needs special protection;   2. After the filter has been working for a period of time, a certain amount of impurities will be deposited in the filter core. At this time, the pressure drop will increase and the flow rate will decrease. The impurities in the filter core need to be removed in time;   3. When cleaning impurities, pay special attention to the stainless steel wire mesh on the filter core. It cannot be deformed or damaged. Otherwise, the purity of the medium after the filter is installed will not meet the design requirements, and the compressor, pump, instrument and other equipment will be damaged;   4. If the stainless steel wire mesh is found to be deformed or damaged, it needs to be replaced immediately.   Selection principles of filters:   1. Inlet and outlet diameters:   In principle, the inlet and outlet diameters of the filter should not be less than the inlet diameter of the matching pump, and are generally consistent with the inlet pipe diameter.   2. Nominal pressure:   Determine the pressure level of the filter according to the higher pressure that may occur in the filter pipe.   3. Selection of the number of holes:   Mainly consider the particle size of impurities to be intercepted, which is determined according to the process requirements of the medium flow. The particle sizes that can be intercepted by various specifications of wire mesh can be found in the table "Filter Specifications" below.   4. Filter material:   The material of the filter is generally selected to be the same as the material of the connected process pipeline. For different service conditions, cast iron, carbon steel, low alloy steel or stainless steel filters can be considered.   5. Calculation of filter resistance loss   Regarding Filters, Automatic Filter,Scraper Self-cleaning Filter, Multi Media Filter,Quartz Sand Filter,Ultra Precision Filter,Cartridge Filter And Parts.

Self-cleaning filters are now used in water treatment in various industries and have become an indispensable equipment for enterprises. However, it is impossible for any equipment to be free of problems all the time, and self-cleaning filters are no exception. So what are the factors that cause problems in the operation of self-cleaning filters? Self-cleaning filters use high-strength stainless steel mesh to handle a large amount of dirt. The service life of self-cleaning filters is relatively long, the cleaning power is relatively high, and it also has the function of saving water.   The main reasons for the abnormal operation of self-cleaning filters are:   1. The selection of filter media for self-cleaning filters. The filter media uses anthracite and quartz sand. The selection of such graded filter media increases the operating resistance due to the small particle size. In the case of incomplete backwashing, it is very easy to produce filter media compaction.   2. Backwash intensity of self-cleaning filter. Backwash intensity = backwash water volume (L)/filtration area (m2) × flushing time (s). The backwash intensity requirement should not exceed the flushing intensity allowed by the upper filter material (anthracite), and it should also ensure that the base quartz sand has enough backwash time to flush it clean. If it is too large, it is easy to leak material, and if it is too small, the backwashing is incomplete.   3. Self-cleaning filter head. Because the plastic material selected for the filter head is not strong enough, it is damaged, resulting in the loss of filter material.   4. The filter material is hardened and leaks material seriously, and the filtering effect is poor. The filter material must be replaced every 6 months to 1 year, and the water quality of the effluent fluctuates greatly, and the oil removal effect is not good. The electric self-cleaning filter still uses uninterrupted water supply during the self-cleaning process. While ensuring the quality of the effluent, it also improves the working efficiency. In this way, the electric self-cleaning filter can not only reduce the pollution of sewage to the river, but also convert sewage into recycled water that can be used by humans, which is also a concrete manifestation of my country's water conservation action.   The water treatment function of the self-cleaning filter is very strong and it is a widely used device. The device is favored by users because of its simple operation and super strong decontamination function. If you encounter abnormal operation of the device, you can learn the reason through this article.   Related Products Automatic Filter,Self-Cleaning Filter,Bag Filter,Multi Media Filter,Ultra Precion Filter,Wedge Wire Screen Plate .

The high-precision oil filter mainly adopts mechanical filtration and gradually reduces the density of the filter screen to achieve the purpose of improving the filtration accuracy. It can be seen that during the operation of the equipment, the first-level filtration is easy to be blocked by impurities. At this time, the oil intake will be less than the oil output, and the oil intake speed is relatively slow.   This oil filter includes a special gear pump driven by a motor, which has the characteristics of low noise, strong self-priming ability, and smooth operation.   The high-pressure pipeline is equipped with an overflow protection device to effectively protect the safety of the hydraulic system.   The thermal relay protection is used to prevent motor damage caused by motor overload.   The coarse filter at the oil suction port protects the pump and extends the service life of the main filter.   A two-stage fine filter is set after the pump to quickly reach a high degree of cleanliness.   The fine filter can choose different precisions according to the different needs of the user to meet the required requirements.   The oil filter housing adopts a quick-open structure, and the upper cover can be opened quickly and quickly without any tools to replace the filter element.   The oil filter panel is equipped with a pressure gauge, which continuously indicates the operating status of the system and the degree of contamination of the filter element when it is working.   1. Cleaning method of coarse filter element:   Remove the upper cover of the first-level filter, take out the filter, and clean it with the same type of clean oil (or gasoline), and then it can be restored to work.   2. Identify the secondary filter and fine filter element, should they be cleaned?   Pay attention to the pressure gauge on the filter. When the filter pressure gauge value reaches 0.3Mpa, stop the equipment, remove the screws on it, and remove the upper cover.   Use clean clean oil (or gasoline) of the same type for cleaning, and use a soft brush to brush the surface of the filter element (the surface of the filter element can be peeled off for cleaning). After completion, it is recommended to use an air compressor to aim at the threaded port of the filter element and blow air from the inside to the outside (this helps to clean the filter element more cleanly).   After cleaning, restore each component and check whether the screw connection is firm.   Related Products,Oil Purification Products,  High Precision Oil Filter, vacuum oil filter, Coalescence dehydrated oil filter cart,Replacement Oil Filter Element,natural gas filter element,etc.

1. Use the information marked on the nameplate of the self-cleaning filter and do not tamper with it at will. 2. When the filter is damaged, do not use it again. Stop the machine and use it after repair. 3. Do not disassemble, assemble or repair it privately to avoid danger to the human body and damage to the machine body. When the machine is damaged, it should be handed over to professionals for repair.   4. Ensure that the self-cleaning filter is in the correct water level. The filter cannot be used without water or insufficient water. 5. Ensure that the power cord and power socket are dry. 6. Regularly maintain and clean the self-cleaning filter, replace the corresponding parts, etc. Before cleaning and maintenance, remember to disconnect the power supply to ensure your own safety.   In addition, the most important thing about the self-cleaning filter is the chip of the self-cleaning filter. The chip is commonly made of stainless steel. After using this material for a period of time, impurities will accumulate, which will affect the work efficiency. Therefore, it is necessary to clean it regularly to remove impurities on the chip.   Also, pay attention to the pressure of the equipment. When the pressure decreases, the flow rate will slow down, resulting in a decrease in the work efficiency of the self-cleaning filter. If this happens, it means that the filter needs to be cleaned and maintained.   To extend the service life of the self-cleaning filter, it is necessary to regularly clean and maintain the filter element. Check the damage of the filter screen from time to time. If it is seriously damaged, it should be replaced in time. The seal between the self-cleaning filter and the connecting frame must be strictly sealed to ensure that there is no air leakage or water leakage. When filtering some high-temperature or high-humidity substances, it is necessary to replace the high-temperature or humidity-resistant filter paper to ensure the normal completion of the work.   Internal Scraping Self-cleaning Filter ,External Scraper Self-cleaning Filter,Basket Filter,Bag Filter ,Automatic Back Flushing Filter,Automatic Filter.Welcome to contact Huatao Filter!    

Installation and commissioning precautions: 1. Operators must hold an operation card and be operated by a dedicated person. 2. If there are obstacles around the filter, they should be removed in time. 3. After the filter is repaired, check whether the connection and fit of each component are firm and whether the tightness is appropriate.   Operation sequence: Note that the equipment is bypass installed:   Sand filling: The inlet and outlet valves of the equipment are closed and isolated from the on-site system. Coarse and fine sand are loaded into the tank in turn. After loading one type, the surface should be flattened before loading the next type. Each tank is loaded in turn.   Sand washing: The initial state of the equipment is the filtering state. Only the inlet valve and drain valve of the equipment are opened, and then the sand in each tank is manually cleaned in turn. The clear water is qualified. The cleaning time of each tank is about 15 minutes.   Filtration starts: Open the inlet and outlet valves of the filter. The operation and backwashing pressure of the filter are adjusted by the outlet valve. During backwashing, the outlet pressure should be kept above 0.25MPa to achieve the best cleaning effect.   Backwashing operation: After the filter has been running for a certain period of time, the filter residue will block the gap, causing a differential pressure to form in the filter inlet and outlet pipes. The pressure difference value can be observed from the inlet and outlet pressure gauges. When the pressure difference reaches the set 0.1Mpa, or when the set filtration time reaches 4h, automatic backwashing is performed.   Equipment maintenance and care:   Check for water leakage   Check whether the sealing parts and auxiliary valves of the equipment are leaking. If there is water leakage, find out the location and cause of the leak and stop the leak in time.   Check for vibration   Whether there is abnormal vibration when the valve is opened and closed. If there is vibration, find out the cause and take timely solutions.   In the Multi Media Filter,except for the shallow sand filter, Quartz Sand Filter also used widely in Liquid Filtration.

Cartridge dust collector plays an irreplaceable role in the field of dust control. Recently, some customers have reported that problems often occur during use and dust control operations have to be stopped. In view of this situation, it is recommended that you should do a good job of daily inspection of the cartridge dust collector, especially pay attention to the following inspections:   1. Clean air chamber and filter cartridge-Regularly check the clean air chamber and filter cartridge of the cartridge dust collector to check for dust accumulation, water vapor or rust spots. When these problems occur, it means that the filter cartridge is damaged or the operation process is incorrect.   2. Inspection of pneumatic air valve-It can be determined according to the daily operating status. If the pneumatic air valve does not work, it is necessary to check whether the gas and electricity are connected properly. If it is confirmed that they are connected properly, check whether the solenoid valve is damaged.   3. Equipment sealing inspection-When there is water vapor like small puddles or rust spots inside the cartridge dust collector box, it means that the water vapor may be caused by leakage from the outside.   4. Inspection of maintenance door-The leakage of the maintenance door is generally caused by improper tightening of the door or problems with the sealing gasket. Correctly tighten the inspection door and replace the aged and deformed gasket.   5. Diaphragm valve inspection opening failure: It may be caused by the continuous operation of the diaphragm valve, excessive accumulation of internal impurities, and severe wear of the diaphragm.

Brush filter and suction filter are somewhat similar. They are two types of self-cleaning filters commonly used nowadays. Users are easily confused when purchasing. Next, let me introduce the difference between the two.   Introduction to brush filter: During the filtration process of brush filter, impurities in the inner layer of fine filter gradually accumulate, and a pressure difference is formed on its inner and outer sides. When this pressure difference reaches the preset value, the filter will start the automatic cleaning process: the drain valve opens, the hydraulic motor chamber and hydraulic cylinder of the main assembly release the pressure and discharge the water; the pressure in the hydraulic motor chamber and the suction pipe drops significantly. Due to the negative pressure, the dirt on the inner wall of the fine filter is sucked by the suction nozzle, flows into the hydraulic motor chamber by the hydraulic motor, and is discharged by the drain valve, forming a suction process. When water flows through the filter hydraulic motor, it drives the suction pipe to rotate, and the hydraulic cylinder piston drives the suction pipe to move axially. The self-cleaning filter suction assembly completely cleans the entire inner surface of the filter through a combination of axial movement and rotational movement. The entire cleaning process will last for tens of seconds. The drain valve is closed at the end of cleaning, and the increased water pressure will cause the hydraulic cylinder piston to return to its initial position, and the filter will begin to prepare for the next flushing cycle. During the cleaning process, the filter machine's normal filtering work is uninterrupted.   Introduction to suction filter:   Water enters from the water inlet, first passes through the coarse filter to filter out larger particles of impurities, and then reaches the fine filter. During the filtering process, the fine filter gradually accumulates dirt and impurities in the water to form a filter impurity layer. Since the impurity layer accumulates on the inner side of the fine filter, a pressure difference is formed on the inner and outer sides of the fine filter. When the pressure difference of the filter reaches the preset value of the filter, the automatic cleaning process will begin. During this period, the clean water supply is continuously flowing, the cleaning valve is opened, and the water pressure in the cleaning chamber and the suction device drops significantly. Through the pressure difference between the filter cartridge and the suction pipe, a suction force is generated between the filter suction pipe and the cleaning chamber through the suction nozzle, forming a suction process. At the same time, the filter electric motor drives the suction pipe to make a spiral motion along the axial direction. The combination of the axial motion and the rotational motion of the suction device completely cleans the entire inner surface of the filter. The entire flushing process only takes tens of seconds. The drain valve closes at the end of the cleaning cycle and the filter begins preparing for the next flushing cycle.   If you need liquid Filtration Equipment or parts , Automatic Filter,Self Cleaning Filter,Inner Scraper Self Cleaning Filter External Scraper Self-Cleaning Filter ,Basket Filter,Automatic Back Wash Cleaning Filter,Bag Filter ,Multi Media Filter,or others,welcome to contact us freely.

The volume of the finished filter cartridge is closely related to the volume of the filter assembly. The main machine using the filter assembly often puts forward the following requirements for the filter:   ① The total height and inlet and outlet distance (width) of the dust collector; ② The total height and diameter of the lower body of the filter cartridge; ③ The total mass of the filter cartridge; ④ The connection method and size of the air outlet; ⑤ A series of performance requirements related to the filtering characteristics such as filtering accuracy.   After the cartridge dust collector has been used for a period of time, the suction force of the dust collector becomes smaller. The more direct and obvious manifestation is that the dust cannot be inhaled by the wind, or only a small part of the dust can be inhaled, and most of the dust particles remain outside. This situation is generally caused by the blockage of the cartridge dust collector filter element, because the blockage of the filter element will lead to a decrease in air volume, resulting in unclean dust removal and a decrease in the fan force. The main reasons for the blockage of the cartridge filter are too high dust-containing gas concentration, too fast filtration speed, too fine dust, sticky dust, unclean filter element cleaning, and damp filter element. If the concentration of the treated dust-laden gas is too high, the filter cartridge dust collector will be clogged, because the space of the V-shaped wrinkles on the surface of the filter cartridge is small, and dust is easy to be retained or accumulated in the V-shaped surface. The pulse filter cartridge dust collector is a purification device specially designed for the treatment of a large number of fine particles suspended in the air that are harmful to the human body during welding, cutting, and grinding. It is suitable for single and double workstations. It has high purification efficiency, is lightweight and flexible, and is equipped with a 2-3 meter long universal suction arm. It is more convenient and flexible in different work locations and easy to operate. The filter element will also be clogged. After the clogging, the dust cannot be removed, and the filtration resistance is never increased. The dust removal system is a key component to ensure the air permeability of the dust collector filter element. Regardless of whether the dust removal frequency or pressure is abnormal, the dust removal filter element will be clogged. If the filter gas velocity of the cartridge filter exceeds the design standard of the filter element, it is easy to cause the fine dust in the exhaust gas to get stuck in the fiber of the filter element. Therefore, the clogging of the filter element, the internal humidity of the filter cartridge dust collector, the high latitude, and the generation of a large amount of steam cause the filter element to be clogged. The dust collector shell is not tightly sealed, resulting in water leakage and wet air entering. The compressed air used for backblowing and dust removal is not clean, and the cold compressed air used for dust removal, etc., will cause the dust filter to become damp and clogged.   After the cartridge dust collector is shut down, if there is condensed water on the surface of the filter, it will be turned on again. When a large amount of dust-laden air enters and high humidity is added, the surface of the filter will become turbid and clogged. When the machine is started at a dew point, a large amount of dust-laden air will enter, and high humidity will cause the surface of the filter to be clogged. If there is no insulation measure or the effect is not good, when there is a large temperature difference between the outside air temperature and the internal temperature of the equipment, condensation will occur in the dust collector, causing the filter to be clogged.   If you need industrial cartridge filter dust collector,Self cleaning air filter ,Bag house dust collectors,dust filter cartridge,Automatic Filter,Bag Filter,Multi Media Filter,Cartridge Filter for  water treatment ,welcome to contact HUATAO.   Your needes,My pursuit!            

Fully automatic self-cleaning filters are widely used in the water treatment industry. Its simple design and good performance enable sewage to achieve better filtering effects. Lijin automatic self-cleaning filters play a very important role in industrial production, and every maintenance accident will affect the production of the factory. Therefore, it is particularly important to improve the service life of the self-cleaning filter and reduce maintenance accidents. So how to improve the service life of the automatic self-cleaning filter element?   First, make sure that the automatic self-cleaning filter is at the correct water level. If the water level is insufficient, the self-cleaning filter will not only fail to play its due role, but also damage the motor system, resulting in failure to work properly. Secondly, the filter screen should be maintained regularly. After a period of use, the fully automatic self-cleaning filter will have impurities accumulated, and the impurities need to be cleaned to improve work efficiency. It is also necessary to regularly check the various components of the filter, especially the filter paper. Once any component is found to be damaged, it needs to be replaced in time.   Fully automatic self-cleaning filter cleaning process:   When the filter inlet and outlet pressure difference reaches the preset value (﹙0.5bar﹚) or the time setting value, the filter will start the self-cleaning process. The whole self-cleaning process includes two steps: opening the diaphragm drain valve located on the upper end cover of the filter; the motor drives the stainless steel brush in the filter to rotate, so that the impurities trapped by the filter are brushed off by the steel brush and discharged from the drain valve. The whole cleaning process takes about 15-30 seconds. During cleaning, the system keeps flowing, and the whole operation process of the filter is controlled by the control box provided with the machine.   If you need self cleaning filter,Automatic Filter,Self Cleaning Filter,Inner Scraper Self Cleaning Filter External Scraper Self-Cleaning Filter ,Basket Filter,Automatic Back Wash Cleaning Filter or others,welcome to contact us freely.
