1. How to choose a self-cleaning filter?
Selecting a good self-cleaning filter to effectively filter the treated medium and ensure it meets the process requirements can protect the safe operation of the lower-end equipment and also guarantee the continuous and efficient operation of the system.
Before choosing a self-cleaning filter, it is necessary to know the system processing capacity, the diameter of the system pipeline, the system pressure, and most importantly, the filtration accuracy. It can also provide the temperature and whether the filter medium is corrosive, viscosity, etc. With these parameters, you can refer to the manufacturer's samples to select the corresponding specifications and models. Also, check if the manufacturer has produced equipment that has been used in the same working conditions and similar industries before. You can make a comparison and reference. In this way, the self-cleaning filter you purchase can ensure that it meets the usage requirements.

2. Features of self-cleaning filters?
Self-cleaning filters are the new generation of fully automatic filtration equipment, which can effectively filter suspended substances in all medium and high viscosity liquids. It adopts a reverse flushing and brush drainage structure, which endows it with the advantages of large filtration area, small equipment volume, compact structure, high filtration efficiency, thorough flushing and low water consumption. Moreover, filtration and drainage are carried out simultaneously, without affecting or interrupting the normal operation of the system. This product can be widely applied in fields such as petroleum, steel, food, chemical engineering, machinery, pharmaceuticals, power, agricultural sprinkler irrigation, municipal works, mining and sewage treatment.

1. It has a large processing capacity and can be used in parallel. The maximum processing capacity of a single machine can reach 1200 m ³ /H. 2. The filtration accuracy can reach up to 50 microns, with a large filtration area and high dirt-holding capacity. 3. The filter unit is designed to be sturdy and durable.
4. The unique cleaning design enables ground load, low water head and uniform sewage discharge functions. 5. It is equipped with motor overload protection, which can effectively protect the motor. 6. It occupies a small area and is equipped with a hoisting unit for convenient maintenance. 7. The connection method with the user's pipeline is flange connection, which is highly versatile. 8. It is suitable for places with high impurity content and harsh working environments. 9. It has strong maintainability and is easy to install and disassemble.
10. The product itself is small in size, low in cost, requires no filter material and has a low maintenance volume. The filter screen cylinder has a long service life and high reliability.
11. It has a high degree of automation, is easy to manage, and can operate unattended for a long time. 12. It has low pressure loss, is energy-saving, and uses water pressure from the main pipeline for backwashing without the need to set up a reverse water source. 13. It is a practical, simple and reliable method that is widely applied to ensure the safe operation of water-using equipment. During any backwashing process, it can maintain an uninterrupted normal operating state.

3. What makes a good self-cleaning filter
The filtration accuracy, capacity and strength of the filter element of the filter should meet the design requirements. When the filter is running under no-load and load conditions, the oil temperature of the reducer should not exceed 65 degrees. The temperature rise does not exceed 30 degrees
When the filter is operating under no-load and load conditions, the noise does not exceed 78B
Under normal circumstances, the average working time of the filter, after deducting the time for replacing vulnerable parts, shall be no less than 8,000 hours

4. Standards for self-cleaning filters
The standard of Wanda Engineering's self-cleaning filter is in accordance with "JB/T10410-2004 Automatic Backwashing Filter for Industrial Water", and it is specially designed and manufactured according to the special requirements of customers.

5. Application of self-cleaning filters
Self-cleaning filters are widely used in the fields of metallurgy, chemical engineering, petroleum, papermaking, medicine, food, mining, power, and urban water supply. Such as: cooling towers, supplementary water systems, air conditioning systems, DC system water filtration, reducing the formation of sediment in heat exchangers, and maintaining cooling effect. Filter surface river water, lake water, sea water, reservoir water, well water and groundwater to remove sand, bacteria, algae, organic matter, etc. The high-pressure water descaling system for hot rolling is an advanced, efficient and easy-to-operate fully automatic filtration device, which is suitable for high-flow water sources with high impurity content, agricultural irrigation, sprinkler irrigation in parks, golf courses, turf watering, as well as filtration of industrial wastewater and circulating water, regeneration of emulsions, waste oil filtration treatment, continuous casting water systems and blast furnace water systems in the metallurgical industry, and high-pressure water descaling system for hot rolling.

6. Precautions for using Self-cleaning filters
The fully automatic self-cleaning filter equipment has been debugged before leaving the factory. Users can directly run it when using the fully automatic self-cleaning filter. When the operating parameters of the fully automatic self-cleaning filter equipment fail to meet the user's requirements, the user can adjust each parameter according to the actual working conditions and accordingly select manual control or automatic control modes for operation. When running for the first time, the following steps should be followed
Check whether the fully automatic self-cleaning filter is in a normal working condition: Observe whether all connections of the fully automatic self-cleaning filter are firm. Check that the electrical control box part of the fully automatic self-cleaning filter is dry.
When the power is connected and the green power indicator light is on, it indicates that the electrical control part of the filter is in a normal working state and the equipment can be put into trial operation.
Note: When plugging in the power supply, make sure to keep your hands dry. Meanwhile, during the operation of the filter, keep the electronic control part dry and prevent water from entering the interior of the electronic control.
