Automatic backwash sewage schematic overview: automatic backwash discharge is a low-quality water filter can use a filter, it has quickly ruled out impurities automatic backwash function, usually installed in the heat exchanger, air-conditioning system or executive body in front of the , occasional flush the impurities. 1, normal working condition manual butterfly valve open that valve plate and the cylinder axis parallel to the plane, (this time also with the cylinder axis parallel wrench) drain valve closed. At this point the water filter from the inlet tube directly into the interior, filtered through the filter from the outlet. 2, work status manually backwash valve closed, ie the valve plate and cylinder plane perpendicular to the axis (point wrench rotate 90 degrees and the cylinder axis vertical), open the drain valve, when the water enters the filter cartridge from the inlet end, because valve closed, the flow has been blocked by the valve plate can only be entered from the front mesh cartridge outside, most from the outlet port, and because of the sewage outfall open, cartridge water discharge pressure after posterior segment decreased, so part of the water and from the filter after mesh network segment recoil cylinder, so as to achieve from the filter external flush impurities adhered to the mesh cylinder walls purposes, impurities and sewage from the sewage discharge port. Automatic backwash sewage Features: ◆ without any support structure, save installation space ◆ need to set the bypass, saving investment costs ◆ can maintain the high flow, but also has low pressure drop ◆ Install flexible and can be mounted horizontally but also to adapt for vertical installation of automatic backwash discharge device selection: In order to be more applicable to the customer's water system, for optimum filtering effect, to provide customers energy saving, energy-saving, water-saving, environmental protection and the highest requirements, Meco valve industry as a leader in water filtration solutions provider, our engineers will use their best technical expertise, extensive operational experience, the best solution for you to make a choice. You choose automatic sewage filter, please consider the following parameters 1, the processing flow of two, three chemical properties of the filter medium, the concentration of suspended solids in the filter media 4, 5 required filtration, pressure filtration pipes comparison table : micrometers (μm) 10 25 30 40 50 80 100 120 150 200 400 800 1500 3000 mesh 1,500,650,550,400,300,200 150 120,100,804,020,105 automatic backwash sewage Technical parameters: Working pressure: 1.6MPa (special Customizable) -100 micron filtration from 3500 micron maximum flow rate of 10000m3 / h.

Automatic backwash discharge the installation and use: 1, automatic sewage filter body in accordance with the direction of the arrow tips connecting pipes 2, the installation should try to consider the sewage outfall in the lower part, easy to sundry emissions. 3, receiving the sewage outfall ditch, sewage pipes should not be too long. 4, the normal filtering, rotate the handle to the working position; sewage backwash when necessary, rotate the handle to the backwash position, open the drain valve. After backwash, the handle to the operating position, close the drain valve.
