Kopin Zezhou lingchuan Yangcheng rapid decontamination filter backwash Shijiazhuang Environmental Protection Equipment Co. earnings are insist on quality first, reputation first business principle, always full of enthusiasm and sincere attitude of cooperation, win-win business philosophy and dedication Welcome to the new and old customers. ◆ Yangcheng backwash filter works: 1, regular timing backwash sewage cleaning sewage, can set the time to 2-24 hours action. When the timer expires, the electric actuator to open the drain valve, filter sewage 30-60 seconds, then turn valve electric actuator will rotate 90 ° to stop the cartridge position, change the flow channels, backwash of sewage 30-60 seconds. Steering valve reset and continue to discharge 3-5 seconds, then close the outfall. 2, the pressure control sewage pressure controller action value can be set to 0.03-0.07MPa, before and after the filter when the pressure reaches the set point pressure controller, pressure controller action, the filter drain valve open, 30 -60 seconds at the end, turn valve reset and continue to discharge 3-5 seconds, close the drain valve. 3, manually controlled by the control box button, you can directly control the clean up sewage. ◆ Overview: YD type Yangcheng backwash filter is automatic backwash filter sewage on the basis of YD, made use of before and after the filter pressure difference (ie resistance) and rely on automation components and electric actuators, automatic completion of filtration, remediation, sewage filter the whole process. Yangcheng YD type filter backwash from the shell, stainless steel filter cartridge, impurities collect segment, electric impurities outfall, electric water valve turned, testing organizations, actuators and control box. By installation type and flow direction divided into two kinds of straight-angle formula. Yangcheng backwash filter performance characteristics and installation: YD-automatic backwash filter sewage except with YD automatic backwash filter sewage all the performance characteristics, but also the following unique characteristics: 1, YD Kim Chang-type filter backwash easy operation and management, high speed filtration, washing simple and reliable, strong backwash capability. 2, time or pressure control mode, fully automatic filter cleaning sewage, and to ensure the efficient use of filters. 3, the control box filters work status, cleaning status, and fault status indicators, and outputs a corresponding signal, easy to operate. 4, rinse, backwash time to adjust, emissions of less than 10% of the normal work flow. 5, the installation reference ZPG automatic backwash filter sewage.

Yangcheng backwash filter structure in the form of automatic sewage filter backwash from the shell, stainless steel mesh filter cartridges, impurities collect segment, impurities outlet and turn the water valve. By installation type and flow direction at right angles to the straight-divided into two. Information from both surplus water treatment company; xj
