Automatic Self Cleaning Filter for Irrigation System
Structure and principle
Automatic brush filter, whose internal structure is composed by 304 stainless steel brush, stainless steel strainer cleaning and other main structure parts. The drive motor and the electric valve automatically finish cleaning and sewage discharging, The operation mode is automatically (or manual operation),with the functions of pressure difference and automatic blow down .The automation component adopts nowadays the most advanced and reliable PLC programmable controller in the world .
When water flows through the filter ,mechanical impurities in water will be intercepted by filtration screen ,when the poly impurity on filter surface area increases and the pressure reaches 0.04MPa,pressure difference switch will send a signal,At the same time, PLC will send out instruction,driving motor start and sewage valve open, Discharge valve to open, is deposited on the filter of impurities are rotating brush down,From pollution discharge outlet,The scrubbing sewage process without the operator, without stopping.meanwhile,The device is also provided with a timing cleaning sewage and manual cleaning draining function,Ensure that in any case the water safety.
