Select the magnetic pump to consider the different structure and configuration.
Magnetic pump has been widely used in a variety of liquid chemical transport, as a production enterprise, in what structure, configuration to produce magnetic pump products, different structure and configuration, will give customers a different use effect.
The first aspect is the pump structure, as a delivery of chemical media magnetic pump products, product design, the first should be considered is the pump reliability, safety, life and other major elements. These main elements are related to whether a pump can be maintained for a long time without maintenance and less maintenance, as well as to the user to bring the cost of consumption, spare parts and can not see the environment, security problems. Therefore, the need to design and manufacture a magnetic pump, in different temperature, under pressure, load conditions, to ensure the stability of the size of the components, in order to achieve long-term operation of the pump without fault, which is a product designer should have ideas and idea. Should not reduce the weight of products and product quality, to achieve lower product costs, low-cost magnetic pump, delivered to the user to use.
The second aspect is the configuration of the pump friction parts. As a magnetic pump product, the consumable parts of the pump are mainly parts that are often frictionally rotating in the liquid, sliding bearings, thrust bearings, bushings. These parts of the wear and tear of the good or bad, will directly affect the life of the pump and the user to replace the cost of parts. International famous magnetic pump production enterprises, regardless of metal or plastic magnetic pump, sliding bearings, thrust bearings, sleeve are used corrosion resistance, wear resistance of silicon carbide material. However, the bending strength of silicon carbide is only 451Mpa, the material is more brittle, impact resistance is poor.
Therefore, in the case of corrosive conditions permit, you can choose the bending strength of 1471 Mpa, more than three times the silicon carbide impact of good tungsten carbide material. Tungsten carbide compared with silicon carbide has good toughness, good impact resistance and so on. In case of pump dry grinding, unlike silicon carbide material will be broken, resulting in internal magnet and isolation sleeve and other parts of the collision, resulting in pump damage. Magnetic pump wear parts using silicon carbide, tungsten carbide material is the highest configuration, that can make the pump can run for a long time without maintenance. Life than the configuration of PTFE graphite, graphite, alumina, silicon nitride and other materials much longer. That can reduce the wearing parts due to wear and tear, poor strength and other factors, resulting in users in a short time often replace the wearing parts and other parts of the cost, as well as environmental, security and other expenses.
