The pump is one of the indispensable and important equipments of the enterprise. Due to the working conditions, corrosion, cavitation, erosion, wear and other phenomena often occur, resulting in equipment failure. Enterprises can only invest a lot of money to buy new pumps, and pay a large number of parts, resulting in a lot of money wasted. The design and manufacture of domestic pumps is basically based on the "metal" concept. Stainless steel and carbon steel are used as the main pump materials. In the face of high corrosion and strong erosion, high nickel alloys and even titanium are needed. Zirconium, niobium and other excellent corrosion-resistant materials, these rare metal materials are expensive and expensive, and the high manufacturing costs and complicated manufacturing processes cause such pumps to be expensive, generally ranging from tens of thousands to several millions. This results in high procurement costs for such pumps. With the development of international advanced pump research and the application of new material pumps, domestic research institutes draw lessons from the development of pump research in Western developed countries. A few domestic companies have started to develop inorganic non-metallic materials such as ceramics, glass steel, graphite and carbon. Plain products and synthetic organic polymer materials such as plastic, glass fiber or carbon fiber reinforced engineering plastics. The development trend of these domestic pumps caters to international trends and soon achieved good results at home.
It is through the effective resolution of such detailed issues that it has realized the advantages of low production costs and strong competitiveness for European, American, Japanese and Korean companies. While domestic companies continue to introduce advanced equipment and employ high-paying management personnel, they ignore the details of such daily equipment management. They only unilaterally reduce labor costs and reduce welfare benefits, resulting in low labor enthusiasm and management confusion. The situation is inevitable.
Obviously, the use of such materials greatly reduces production costs, does not require the purchase of high-value metals, does not require special equipment and professionals, and it works well, has a longer life, and is simpler to repair. Its great advantage is by no means a traditional pump material. Can compare. The application of new materials for the pump body has greatly reduced the cost of the pump material and maintenance and repair costs.
