Routine maintenance
1. Regularly check the remote pressure gauge. When it is found that the digital display of the cabinet and the remote pressure gauge mean that the readings of the parts used to indicate the corresponding time in the clock are inconsistent, they can be corrected by the pressure calibration potentiometer. If you find that the pointer of the watch slides, you can remove the front glass cover of the watch and fix it again.
2. Regularly check the running current of the pump motor. Its value should not exceed the rated output current of the inverter to avoid damage to the inverter. 由变频控制柜、无负压装置,自动化控制系统及远程监控系统、水泵机组、稳压补偿器、负压消除器、压力传感器、阀门、仪表和管路系统等组成。 Frequency conversion water supply equipment is composed of frequency conversion control cabinet, no negative pressure device, automatic control system and remote monitoring system, pump unit, voltage stabilizer compensator, negative pressure canceller, pressure sensor, valve, instrument and piping system. The pump motor should be maintained regularly.
3. The temperature in the frequency conversion control cabinet must not exceed 50 ° C, otherwise corresponding measures should be taken to reduce the temperature.
4. Regularly check whether the check valve of the water pump is malfunctioning. If it fails, repair it in time, otherwise there is a danger of damaging the inverter. Constant-pressure water supply equipment can maintain a constant water supply pressure, which can maintain a balance between water supply and water use, that is, when there is more water, there is more water, and when there is less water, it is less, thereby improving the quality of water supply.
5. Regularly inspect whether the screws of the electrical components in the cabinet are loose, and whether the contacts of the contactor are burned or damaged. The time should be no less than once every six months (power failure is required).
6. If the inverter fails, it should be checked carefully according to the inverter instruction manual. It cannot be powered on blindly.
7. During normal operation, do not randomly switch on the PLC controller.
8. If one of the water pumps is repaired, the water supply equipment can be operated in a single pump mode, and the operation pump can be selected.
