Pump is an indispensable enterprise one of the important equipment, affected by the working conditions, often corrosion, cavitation, erosion, wear and other phenomena, leading to equipment failure. Enterprises can only invest a lot of money to buy a new pump, and pay a large number of parts, resulting in a lot of money wasted. Domestic pump design and manufacturing basically follow the "metal" idea, that is, stainless steel, carbon steel as the main pump material, the face of high corrosion, strong scouring environment, you need high nickel alloys, and even the use of titanium, Zirconium, tantalum and other fine corrosion-resistant materials, these rare metals and expensive price fluctuations and large, and high manufacturing costs and manufacturing processes and other complex causes of such pumps are expensive, generally tens of thousands to millions of dollars, but also This has resulted in high procurement costs for such pumps. With the development of international advanced pump research and the application of new material pump body, domestic scientific research institutions draw on the development ideas of pump research in western developed countries. A few domestic enterprises start to develop inorganic non-metallic materials such as ceramics, fiberglass, graphite and carbon Synthetic products and synthetic organic polymer materials such as plastic, glass fiber or carbon fiber reinforced engineering plastics. The development trend of these domestic pumps to meet the international trend, and soon achieved good results in the country. read more:
