Common faults of water pump controller

2022-05-27

I believe that everyone should have access to water pumps, especially now that there are many high-rise buildings. For high-rise residents, the water pressure is very low. If there is no pump, it cannot be used normally. The smart water pump has been used, so what are the common faults of the smart water pump controller?

1. The upper limit will not stop, that is, it will not stop when the pressure reaches high pressure;

2. The lower limit does not start, that is, the pressure reaches the lowest level, and the water pump still does not start;

3. Overload protection occurs, that is, the model of the motor and the controller do not match;

4. There is phase loss protection, and the inlet line of the water pump is loose.

Common faults and solutions of water pumps:

1. The work cannot be started. First, check whether the power supply of the power supply is normal, whether the connection of the power cord and the switch is wrong, and whether the fuse is burnt. If these conditions occur, it must be repaired in time.

2. Mechanical failure in the pump, such as too much packing, debris between the impeller and the pump body, which leads to blockage. This fault can be solved by loosening the packing and cleaning the debris in the pump body, or directly replace the pump with a new one. axis.

3. The pump body heats up, the bearing is damaged, the gap between the rolling bearing or the bracket is too small, etc., which will cause the pump body to heat up. It is very simple to solve this fault. First of all, if the bearing is seriously damaged, you can replace the new bearing, or appropriate Add a spacer between the bracket and the bearing, so that the gap will be narrowed, and the tightness of the tape can be properly adjusted to make the bearing rotate more smoothly.

4. The flow rate is small. The main reason is that the speed is not matched and the belt is slipping, which leads to a lower speed and a smaller water flow. You can reset the speed and return to normal, or clean the grease on the belt and the tightness of the condition.
