[answer] acid resistant pump is a kind of machine that can lift liquid, transport liquid or increase the pressure of liquid, that is, turn the original mechanical energy into liquid energy. The acid resistant pump is a pump developed and produced by using acid resistant materials on the basis of the pump. The main reason why most acid resistant pumps can resist acid is the material of the pump. Generally, acid resistant pumps use non-metallic materials as the flow passage component materials of the pump, such as "polyethylene, polypropylene, polyfluoroethylene propylene, etc." among them, polyfluoroethylene propylene is one of the best acid resistant materials, which can basically resist the corrosion of any acid medium, and is called the king of plastics. The acid resistant pump product is suitable for transporting various corrosive media under the temperature of -20 ℃ ~ +120 ℃. Its overflow part is all made of plastic alloy (polytetrafluoroethylene, perfluoroethylene propylene and other materials) through reasonable formulation, molding and processing. The acid resistant pump integrates the advantages of a variety of plastics, has strong corrosion resistance, and has the advantages of high mechanical strength, no aging, no toxin decomposition, etc., and is used to transport various strong Ideal equipment for weak acid. For a long time, the selection of acid resistant pump has been one of the most headache problems for chemical industry practitioners. A little carelessness may damage the equipment, or cause accidents or even disasters. According to relevant statistics, about 60% of the damage of chemical equipment is caused by corrosion. Therefore, when selecting chemical pumps, we should first pay attention to the scientificity of material selection. There is usually a misunderstanding that stainless steel is a "universal material". It is very dangerous to hold stainless steel regardless of medium and environmental conditions. Therefore, it is necessary for factory operation and chemical production to reasonably select acid resistant materials. In the future, with the rapid development of science and technology, acid resistant pumps will play a more and more important role in chemical, metallurgical, electric power, papermaking, food, pharmaceutical, synthetic fiber and other industries. At the same time, there will be higher requirements for pump equipment. And the design requirements are more reasonable, the structure is simple, and the use is convenient. It will have good application and development prospects in the future.
