Common troubleshooting method for single-phase energy-saving water pump unit

1. The pump does not work. If the mechanical part is stuck, the assembly clearance should be adjusted to make it flexible; if the line fails, the circuit should be repaired.

2. The flow rate is reduced. If the head is too high, the head should be adjusted; if the bottom valve or impeller is blocked, the blockage should be removed; if the line is too long, the degree of curvature is too small, the pipe should be shortened and the bending angle should be changed.

3. The pump does not produce water. If the suction pipe is not tight and the pipe joint leaks, the joints should be repaired and sealed; if the air is not exhausted, the exhaust bolts should be unscrewed to drain the air; if the water in the pump is not filled, Fill the pump with water; if the seal leaks and the pump shaft leaks, replace the seal.

4. The motor is overheated. If the power cord is too long and the diameter is small, the line should be shortened and the power cord with a large diameter should be replaced. If the lift of the pump is too low, the working time should be shortened; if mechanical friction is used, the gap should be adjusted to eliminate friction.
