Feed pump of filter press is a common equipment in industry, but the protection technology of feed pump of filter press needs to be improved. Stainless steel and carbon steel are still used as main pump body materials in domestic pump design and manufacture. Facing the environment of high corrosion and strong erosion, high nickel alloy is needed, and even excellent corrosion resistant materials such as titanium, zirconium and tantalum are used. These rare metal materials are expensive and their prices fluctuate greatly, and the manufacturing cost is high and the manufacturing process is complex, which cause corrosion resistance. The high price of filter press pumps results in the high cost of purchasing such pumps.
Corrosion Resistant Pressure Filter Feed Pump
With the development of science and technology, polymer composites are widely used in pump and valve industry. Compared with rare metal materials, they greatly reduce production costs, and have better use effect, no less than other materials. With the development of science and technology, it will not remain in the existing technical situation. It is believed that the anti-wear technology of corrosion-resistant pumps will continue to develop.
Pump corrosion not only reduces production efficiency, but also wastes a lot of money. With the development of international advanced pump body research and the application of new material pump body, domestic scientific research institutions draw lessons from the development ideas of western developed countries on pump body research. A few domestic enterprises and institutions begin to develop inorganic non-metallic materials such as ceramics, glass fiber, graphite and carbon products, and synthetic organic polymer materials such as plastics, glass fiber or carbon fiber reinforced engineering plastics. These domestic development trends of corrosion-resistant pumps cater to the international trend, and soon achieved good results in domestic use.
