Structure and principle: 
 This filter is mainly composed of high-quality carbon steel or stainless steel Simplified, Johnson, filter, flow direction valve, differential pressure controller, electric control box and sewage devices. When the filters work, the flow direction valve is turned on, the flow from the inlet into the filter, and after a mesh filter into the export. This machine adopts pressure control, positioning control of the self-cleaning filters. When the import and export of filter differential pressure up to a set value or the timer reaches the preset time, the electric control box to send a signal to the drain valve is open (flow direction valve is turned on), water rinse sticky filter on the inner wall of the magazine is further flush discharge, when the flow direction valve is fully closed state, the water is forced to the outside to enter the filter from the filter inlet section of mesh, most of the net fluid outflow from the export, part of the net fluid and from the filter the outside of the filter internal (because the system will be in a relief state, the internal pressure of the filter is less than the outside pressure), which filter backwash, special equipment, Johnson network makes the jet effect inside the filter, any magazines from smooth on the inner wall washed away. When the filter pressure drop replies normal or timer setting time after the end of the electric drain valve closed, the flow direction valve to open. Throughout the process, the material flow, to achieve a continuous, automated production. 
 Features: 
 ① Fully automatic cleaning of electrical installations (2) filtration precision can be 3500 mm 200 mm ③ cleaning is simple ④ or according to the requirements made of seawater corrosion resistant shell or stainless steel body ⑤ backwash constant flow, minimal water consumption: not more than the total flow % 
 Technical parameters:
