Magnetic pumps have been widely used in the transportation of various liquid chemicals. As a manufacturing enterprise, what kind of structure and configuration are used to produce magnetic pump products, and different structural forms and configurations will bring different uses to customers. effect.
The first aspect is the structure of the pump. As a magnetic pump product that transports chemical media, the main factors such as the reliability, safety and service life of the pump should be considered in the product design . These main factors are related to whether a pump can keep running for a long time without maintenance and less maintenance, as well as consumption costs, accessories costs and invisible environment and safety issues for users. Therefore, it is necessary to design and manufacture a magnetic pump that can ensure the stability of the dimensions of various components under different temperature, pressure, and load conditions, so as to achieve long-term pump operation without trouble. This is a product designer's thinking and idea. Should not be used to reduce product weight and product quality, achieve product cost reduction, low-cost, low-cost magnetic pump, delivered to users.
The second aspect is the configuration of the friction parts of the pump. As a magnetic pump product, the wearing parts of the pump are mainly parts that often rotate and rub in liquid, sliding bearings , thrust bearings, and bushings . The wear resistance of these parts will directly affect the service life of the pump and the cost of replacing the parts by the user. Internationally renowned magnetic pump manufacturers, whether metal or plastic magnetic pumps, sliding bearings, thrust bearings, and bushings are made of silicon carbide with excellent corrosion resistance and wear resistance. However, the bending strength of silicon carbide is only 451Mpa, the material is relatively brittle and the impact resistance is poor.
Therefore, if the corrosive conditions permit, you can choose a bending strength of 1471Mpa, which is more than three times higher than silicon carbide and good tungsten carbide. Compared with silicon carbide, tungsten carbide has the advantages of good toughness and good impact resistance. In the case of dry grinding of the pump, it will not be broken like silicon carbide material, which will cause the friction between the inner magnetic steel and the isolation sleeve and other parts, resulting in damage to the pump. The wearing parts of magnetic pump are made of silicon carbide and tungsten carbide, which can make the pump run for a long time without maintenance. The service life is much longer than that of PTFE, graphite, alumina, silicon nitride and other materials. It can reduce the cost of frequent replacement of consumables and other components in a short time due to factors such as non-wear resistance, poor strength and other factors, as well as environmental and safety costs.
