Pump station: single pumping station system, including power supply, electric pump control automation, condition instrument, video monitoring, communication network and lighting electrical pumping station construction part two (control system) adopts our mature product KPS2000 series pumping station automatic control system.
The main function configuration of the control system:
The monitoring and protection of the submersible pump;
The monitoring and protection of the high voltage supply and use system;
金沙3983cc登录Monitoring and protection of auxiliary equipment;
Monitoring and protection of field working conditions.
金沙3983cc登录According to the characteristics of the submersible pump station, the control system can monitor and control the drainage system in the ground control room to the underground pumping station, pump unit and valve and so on. It can also operate locally in the underground pump room. And the control process can be fully automated, both in distance and in place.
