The filter is an indispensable device on the transmission medium pipeline and is usually installed on the inlet side equipment of pressure reducing valve, pressure relief valve, constant water level valve, and other equipment of the Fanggong filter. The filter consists of a barrel, a stainless steel filter, a drainage part, a transmission and an electrical control part. After the water to be treated passes through the filter cartridge of the filter screen, impurities are blocked. When the cleaning is required, the removable filter cartridge can be removed and reinstalled after processing. Therefore, the use and maintenance are extremely convenient.
When the filter is working, the water to be filtered enters through the nozzle and flows through the screen.
Through the export of the user into the pipeline required for the process cycle, the particles in the water are trapped inside the filter. As a result of this continuous cycle, more and more particles are being trapped, the filtration rate is getting slower and slower, and the imported sewage still enters incessantly, and the filter pores will become smaller and smaller, which will create pressure between the inlet and outlet. Poor, when the degree difference reaches the set value, the differential pressure transmitter transmits the electrical signal to the controller, and the control system starts the drive motor to drive the shaft through the transmission assembly, and the sewage outlet is opened and discharged from the sewage outlet. After the cleaning is completed, the pressure difference is reduced to the minimum value, the system returns to the initial filter state, and the system operates normally.
