Hand brush type /P sewage filter backwash
Hand brush type /P structure and principle of sewage filter backwashing
A filter structure is composed of brush bristles (bone and nylon brush than more with high strength and high temperature resistance, corrosion resistance and aging properties) and stainless steel parts, stainless steel screen brush device is installed on the inside. A simple handle is arranged outside the filter cover, and a handle is only needed to be rotated gently, which can be removed from the filter screen and is discharged through the discharge port. In the process of brushing the water without interruption, does not need to stop and remove filter cleaning filters, high quality carbon steel cylinder shell.
P type recoil sewage filter is mainly composed of high quality carbon steel tube, special structure of stainless steel composite filter net, butterfly valve and drainage device. When the filter works, the butterfly valve is in the open state, the water flow from the inlet into the filter, through the filter to the outlet. When the filter needs sewage, close the valve, open the drain valve, water filter through the first half of the filter, some water into the system by exports, the remaining water from the filter into the inside of the outer half, the sewage outfall discharge, to reverse automatic flushing ears filter function. The whole process system can be run normally, no need to stop.
Hand brush type /P sewage filter backwash specifications and dimensions
Working pressure 1.0MPa (indicating the pressure more than this, please when ordering) working temperature are less than 150 pressure loss less than 0.015MPa filtering accuracy of d=1.2mm. Filter accuracy and size can be customized according to user requirements, the flange connection by GB-9119.8-8.8 standard.
Hand brush type /P sewage filter backwash installation
Hand brush filter can be installed horizontally or vertically, but should pay attention to the flow direction and the shell of the arrow must be the same. Vertical installation requires that the direction of flow is from top to bottom.
When the pressure difference between import and export to 0.04MPa, to open the drain valve, manual gently turn the handle scrubbing filter, until the water quality of the effluent outfall clear after stopping cleaning and sewage, the sewage system during normal operation, no downtime.
P type automatic sewage filter should be horizontal or vertical installation, when installed vertically, the flow direction should be from top to bottom, the installation should pay attention to the direction of the arrow on the shell must be consistent with the direction of flow, during normal operation, the butterfly valve is open, when you need to discharge, closed butterfly valve, open the drain valve until the discharge water to clear so far. Close the sewage valve, open the butterfly valve, that is, the completion of the sewage process, equipment to enter the normal operation state.
