Summary
Qpg type full-automatic blowdown filter is a kind of filter which uses the pressure difference between the incoming and outgoing water flow to automatically control and remove the impurities in the filter screen through the differential pressure controller and discharge the impurities. It is mainly composed of the shell, filter screen, differential pressure controller, blowdown valve, electric speed reducer, decontamination mechanism and so on. It can be widely used in air conditioning pipeline system, water supply and drainage system and various workers Industrial process system.

working principle
The water enters from the water inlet and flows out from the water outlet after being filtered by the filter cartridge. The filtered sundries stay in the filter cartridge or stick to the filter net. When the dirt accumulates to a certain program, the filter net hole is gradually blocked, and the pressure difference between the front and the back of the filter net increases. When the pressure difference increases to the set value on the differential pressure controller, the differential pressure controller will automatically start the motor and start the blowdown The valve and motor drive the steel brush to rotate to remove the sundries on the filter drum net. The water flow flushes and discharges the impurities and dirties from the drain outlet. The water pressure difference before and after the filter screen reduces and returns to the original state. The differential pressure controller automatically closes the motor and the drain valve and returns to the normal working state.

Use characteristics
1. The filter has high degree of automation, automatic operation in the whole process, and can be unattended.
2. The filter can work under the full flow, which not only keeps the high flow rate, but also has the low pressure drop, avoiding the surface stains caused by the low flow rate.
3. When installing, pay attention to the arrow on the shell must be consistent with the flow direction of the medium.
4. The outlet of the filter shall be kept a certain distance from the measuring element or actuator, generally 6 to 10 times of the pipe diameter.
