The controller is a new generation of energy-saving water supply equipment, mainly used in high-rise buildings without water tower, fire pump constant pressure water supply, multi pump control, pipeline pressure stability, improve water quality, reduce two pollution, high efficiency, no tower water supply automatic control system can realize the unattended. Today, Xiao Bian talk about the control cabinet maintenance related matters!

1.disconnect the power supply, check whether the frame of the control cabinet has a reliable grounding, and make the grounding resistance not more than 4 ohms.

2.the control cabinet has different nature of the voltage (DC 110V, AC single-phase 220V, three-phase AC), in the maintenance of the circuit must be clear, to prevent short circuit accidents.

3.All the electrical switches on the control cabinet should be flexible and reliable, with no significant noise, and the connecting wires, terminals and terminals shall be free of looseness. The steel wire at the end of the contact wire of the movable contact shall be free of fracture.

4.with a soft brush or blowing dust removal plate plug and all parts of the electromagnetic switch, and check the control cabinet electric switch contact state, contact, coil insulation and mechanical components of the appearance of the action is reliable.

5.when fusing the fuse, the fusing current should be matched with the current of the circuit.
