[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.
