1. Disconnect the power supply and check that the rack of the control cabinet has a reliable grounding and that the grounding resistance is not more than 4Ω.

2. The control cabinet has different voltages (DC 110V; AC single-phase 220V; three-phase AC), the circuit must be clearly identified during maintenance to prevent short-circuit accidents.

3. All electrical switches on the control cabinet should be flexible and reliable, with no significant noise. There should be no looseness at the junction and the terminal of the connecting wire. The wire at the junction of the moving contact cable should be free of breakage.

4. Use a soft brush or blower to remove the dust from the panel insert and all the electromagnetic switch parts, and check the status of the electrical switch contacts in the control cabinet, the contact conditions, the insulation of the coil appearance and the action of the mechanical components.

5. When replacing the fuse, the fuse current should match the current of the loop.

Basic role

The control cabinet is mainly used for high-rise buildings without tower water supply, fire-fighting deep well pump constant pressure water supply, etc. According to the real-time water working conditions, the closed-loop adjustment of the pump speed is required. The well-known brand inverter, intelligent controller, pressure sensor and water pump are used to form a closed-loop control system. .

Multi-pump control, stable pipe network pressure, improved water supply quality, reduced secondary pollution, high power saving efficiency, can achieve unattended automatic control system without tower water supply.
