Routine maintenance and overhaul of the magnetic pump method: five maintenance instructions magnetic pump: 1, the shaft off: magnetic pump shaft material is 99% alumina ceramic, the main reason for the shaft is broken, because the pump is running empty , Dry shaft bearing shaft twist off. Open the pump inspection can be seen when the bearing has been seriously damaged to prevent the pump broken off the main method is to avoid the air pump running. 2, bearing damage: Magnetic pump bearings are made of high-density carbon material, in case of pump water or pump impurities, it will cause the bearing damage. Cylindrical shaft coupling inside and outside the rotor between the coaxial requirements if not guaranteed, will also directly affect the bearing life. 3, Lack of Head: The reasons for this failure include: there is air in the transmission medium, the impeller is damaged, the speed is not enough, the proportion of liquid to be transported is too large, and the flow rate is too large. 4, the lack of flow: the main reasons for lack of flow caused by: impeller damage, speed is not enough, the lift is too high, there are clogged tubes, etc. 5, the magnetic pump can not play the liquid: magnetic pump can not play the liquid is the most prone to pump Fault, the reason is more. First of all, check whether the pump suction pipe leaks, check the suction pipe air is exhausted, the amount of liquid filled in the magnetic pump is sufficient, inhalation tube whether there is debris clogging, check whether the pump is reversed (Especially after changing the motor or overhauling the power supply line), you should also pay attention to whether the suction height of the pump is too high. If the above inspection still can not be solved, the pump can be disassembled and checked to see if the pump shaft is broken. Check whether the moving ring and the static ring of the pump are intact, and whether the entire rotor can move in a small amount. If the axial movement difficulties, can check whether the carbon bearing with the pump shaft is too close.
