Firs :tSummary of daily maintenance work of swimming pool pumps
1. Check frequently and clean the dirt basket regularly. When cleaning, do not knock the dirt basket. If the dirty basket is damaged, it should be replaced in time.
2. Regularly check the pump head cover sealing ring. If it is damaged, please replace it in time.
3. Keep the motor clean and keep the motor air outlet unobstructed.
4. Occasionally, the shaft sealing ring of the motor will be worn out and should be replaced in time.
5. In winter, the water in the pump head should be removed, the inside and outside of the pump should be cleaned, and the pump should be stored in a dry and well-ventilated room.
TWO:The water pump cannot pump water normally
1. Check whether the pump head has been filled with water, whether the O-ring of the pump head cover is clean, whether the installation position is correct, and the pump head cover has been closed and locked.
2. Check whether all suction and outlet valves are open and not blocked, and the water level is higher than all suction ports.
3. Block the suction port closest to the water pump and check whether the water pump produces suction.
3. If the pump does not produce suction, and the pump has injected enough water
1. Tighten all connectors.
2. Check the voltage to ensure the speed of the water pump.
3. Turn on the water pump to check whether the motor main shaft or water wheel is blocked or jammed.
Fourth:the pump makes an abnormal noise when it is working
1. Check if the suction pipe is leaking, causing the pump to rang.
2. Check whether the suction pipe is blocked or the suction pipe is too small or the outlet pipe is too large. If necessary, increase the suction pipe or use a valve to control the amount of water from the outlet pipe.
3. Check if there is vibration caused by improper installation of the pump.
4. There is a foreign body in the water pump head.
5. Motor bearings are damaged due to wear, corrosion or long-term overheating.
Five: the motor cannot start normally
1. Check whether the wiring of the power cord is correct or loose, whether the switch and relay are turned on, and whether the leakage protection switch and the fuse are blown.
2. Check whether the rotation of the motor spindle is smooth.
3. Check whether the centrifugal switch is stuck in the "on" position.
SIX:The motor suddenly stops running
1. Check the circuit and wire interface, etc.
2. Check whether the voltage delivered to the motor is too low (usually the current is insufficient due to the small power cord).
