The self-priming magnetic pump is a kind of non-contact torque transmission through the magnetic drive to replace the dynamic seal with a static seal, so that the pump can achieve the purpose of completely leak-free. It consists of a self-priming pump, a magnetic drive, and an electric motor. The key component, the magnetic drive, is composed of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation sleeve. It has many characteristics such as good internal sealing and lower energy consumption. When using it, attention should be paid to preventing particles from entering, dry friction and other matters and problems.
Faults, causes and solutions of self-priming magnetic pump
1. The vacuum gauge indicates a high vacuum, and the pump still does not absorb water.
Reason: The bottom valve is not opened or seriously blocked, the suction pipe has a large resistance, and the suction height is too high.
Solution: Check the flexibility of the bottom valve valve, remove the blockage, make the suction pipeline as simple as possible, and reduce the suction height.
2. The sound in the pump is abnormal, and the pump does not produce water.
Reason: The resistance of the inlet pipe is too large, the water absorption height is too large, air enters the water suction pipe, and the temperature of the conveyed liquid is too high.
Solution: Check whether the inlet pipeline is blocked, clean the bottom valve, lower the liquid temperature or lower the water absorption height.
3. The outlet pressure gauge indicates that there is pressure, and the pump produces little or no water.
Reason: The water outlet pipe has large resistance, the steering is wrong, the impeller is blocked, and the rotation speed is not enough.
Solution: reduce the pipe resistance, check the motor rotation, remove the impeller blockage, and increase the speed.
