Self cleaning filter is a kind of automatic precision equipment that uses the filter screen to directly intercept the impurities in the water, remove the suspended solids and particulate matter in the water body, and purify the water quality. It can reduce the generation of system fouling, bacteria and algae, and rust, so as to protect the normal operation of other equipment in the system.
Yuwei self cleaning filter overcomes many shortcomings of traditional filtration products, such as small processing capacity, frequent cleaning of filter bags and filter elements, filtration parts need to be disassembled and cleaned, and the filter status cannot be monitored. It can filter raw water and automatically filter the filter. The net is used to clean and discharge the sewage, and the system filters continuously during the cleaning and discharge, which can monitor the working status of the filter, and the degree of automation is high. It covers the needs of various filtration precisions from 50um to 800um.

The liquid enters the filter from the water inlet, the impurities in the material are filtered out through the filter screen, and then intercepted to the inner wall of the filter screen, and the filtered liquid is discharged from the outlet.
During the filtration process, the impurities in the inner layer of the filter screen gradually accumulate. When the sewage discharge condition is reached, the brush motor and the sewage outlet valve are automatically opened, and the accumulated impurities are cleaned by the brush and then discharged from the sewage outlet.
Discharge Condition
During the filtration process, the impurities in the inner layer of the filter screen gradually accumulate. When the sewage discharge condition is reached, the brush motor and the sewage outlet valve are automatically opened, and the accumulated impurities are cleaned by the brush and then discharged from the sewage outlet.
Filters with various pressure ranges can be designed and produced according to user needs; filters with temperatures up to 95C are produced through special processes. For filters that need to work in cold conditions, a special filtration control system will be used; for seawater corrosion Special materials such as nickel and titanium alloys are selected, and the filter is specially processed; according to the specific working conditions and requirements of users, targeted solutions can be provided.
The self-cleaning water filter is an automatic precision equipment designed to directly intercept impurities, suspended solids, and particulate matter in water. Its main advantage is that it automatically cleans and discharges sewage without interrupting the water filtration process. It overcomes the shortcomings of traditional filters, such as the need to frequently disassemble and clean filter bags or elements, and it features a high degree of automation with an intelligent PLC control system.
As liquid passes through the stainless-steel wedge screen, impurities are trapped on the inner wall. When the accumulated impurities create a predetermined pressure difference, or when a set timer is reached, the automatic cleaning cycle begins. The brush motor activates to rotate the 316L stainless steel brushes, which scrub the inner screen. Simultaneously, the electric drain valve opens, discharging the brushed impurities out of the sewage outlet. The cleaning cycle typically takes only 10 to 60 seconds.
The filter is manufactured from stainless steel or carbon steel and can handle capacities ranging from 20 to 2,350 m³/h depending on the model (e.g., YWQX-2 to YWQX-24). It operates at a maximum pressure of 0.1 to 1.6 MPa and a maximum temperature of 95°C. The filtering precision ranges from 100 to 3000 μm, and the cleaning can be controlled via pressure difference, a screw switch, or a button switch.
This versatile equipment is widely utilized in multiple industries. It is heavily used in the iron and steel industry (for cooling water and high-pressure descaling), the automotive industry (coating lines and engine manufacturing), power plants (boiler high-purity water pretreatment), petrochemicals, agricultural irrigation, papermaking, and mining. It is also an essential component for municipal water supply and general industrial wastewater and circulating water treatment.
Yes. The manufacturer can design filters for various pressure ranges or extreme conditions. For applications involving cold weather, a specialized filtration control system can be installed. For highly corrosive environments like seawater treatment, the filter can be specially manufactured using anti-corrosive materials such as nickel and titanium alloys to ensure durability and optimal performance.
