Magnetic pump five maintenance instructions:
1, the shaft breaks
Magnetic pump shaft material used is 99% of the alumina porcelain, the main reason for the shaft is broken, because the pump runs dry, bearing dry grinding and the 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 coupling inside and outside the rotor between the coaxial requirements if not guaranteed, it will directly affect the bearing life.
3, lack of lift
The reasons for this failure are: transmission medium air, impeller damage, speed is not enough, the proportion of liquid transport is too large, the flow is too large.
4, lack of traffic
The main reasons for the lack of flow are: impeller damage, speed is not enough, the lift is too high, the tube is clogged with debris
5, magnetic pump can not hit the liquid.
Magnetic pump can not play the liquid pump is the most prone to failure, its reasons are 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 to check whether the pump shaft is broken or not. 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 of axial direction. If the axial movement difficulties, can check whether the carbon bearing with the pump shaft is too close.

According to the different production methods of calcium carbonate, calcium carbonate can be divided into Heavy Calcium Carbonate, light calcium carbonate, colloidal calcium carbonate and crystalline calcium carbonate. White solid, tasteless and odorless. There are two forms of amorphous and crystalline. The crystal type can be divided into orthorhombic crystal system and hexagonal crystal system, which are columnar or diamond-shaped.
Calcium carbonate is widely used in filling polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), acrylonitrile butadiene-styrene copolymer (ABS) and other resins. The addition of calcium carbonate has a certain effect on improving certain properties of plastic products and expanding their application range. In plastic processing, they can reduce resin shrinkage, improve rheology, and control viscosity. It can also play the following roles:
(1) Improve the dimensional stability of plastic products;
(2) Improve the hardness and rigidity of plastic products;
(3) Improve plastic processing performance;
(4) Improve the heat resistance of plastic products;
(5) Improve the astigmatism of plastics;
(6) It can make the product have some special properties;
(7) Reduce the cost of plastic products.
