Electric brush-type self-cleaning filter

　　Product introduction

　　The electric brush-type self-cleaning filter produced by our company is divided into three types: JFDFW, JFDFY and JFDFL. It is a kind of precise equipment that directly intercepts the impurities in the water with a filter screen, removes suspended matter and particulate matter in the water, reduces turbidity, purifies the water quality, reduces the production of system dirt, bacteria，algae, rust and so on, purifies the water quality and protects other equipment of the system to work normally. Water enters the body of the self-cleaning filter from the water inlet. The motor drives the bull stick. The cleaning brush connected to the bull stick is used as the cleaning mechanism. The impurities accumulated on the filter screen are brushed off and driven out by the water flow. Because of Intelligent (PLC, PAC) design, the system can identify the degree of impurity deposition automatically, and Signal the drain valve to discharge automatically.

　　operating principle

　　When the water enters the filter screen from the inlet, impurities are trapped on the inner wall of the filter screen, the filtered clean water flows out from the outlet. When the impurities on the inner wall of the filter screen accumulate more, the pressure difference between the inlet and outlet of the self-cleaning filter reaches the set value or the cleaning time, the filter will start the self-cleaning process. The entire self-cleaning process consists of two steps: the automatic drain valve located on the self-cleaning filter opens; The motor drives the cleaning brush in the filter screen of the self-cleaning filter to rotate, and the impurities intercepted by the filter screen are cleaned and brushed down and discharged from the drain valve. The system continuously flows during cleaning, and the entire operation process of the self-cleaning filter is controlled by an intelligent control box. Control is realized by PLC. There are three control modes: pressure difference, time and manual, which can be set arbitrarily.
