Centrifugal pump is one of the common and commonly used products in pump products. It uses the rotation of the impeller to make the water centrifugally move to work. There are many types. According to different classification methods, the types are also different. By nature, the centrifugal pumps commonly used in chemical production mainly include water pumps, corrosion-resistant pumps, oil pumps, submerged pumps, impurity pumps, and canned pumps. The following will introduce these types of centrifugal pumps in detail.
Among the above types of pumps, clean water pumps can be said to be the most widely used pump products, with simple structure and easy operation; corrosion-resistant pumps are mostly small pumps, which are mainly used to transport acid and alkali. Corrosive liquids such as concentrated ammonia water and concentrated ammonia water are also characterized by their corrosion resistance. Therefore, when transporting these corrosion-resistant items, a corrosion-resistant pump must be used; the oil pump is mainly used to transport petroleum products. Therefore, the oil pump The sealing performance must be good.
In chemical production, as a process pump (process pump), the submerged pump has a wide range of applications. The submerged pump is often installed in the liquid storage tank, and it can also transport various corrosive liquids. However, the submerged pump There is a disadvantage that the efficiency is relatively low; the impurity pump is mainly used to transport some suspensions containing solid particles, thick slurries and other items, which are not easy to block, easy to disassemble, wear-resistant and other characteristics. There are also many, including sewage pumps, sand pumps, mud pumps, etc.; canned pumps, also known as leak-free pumps and sealless pumps, are mainly used to transport flammable, explosive, highly toxic or radioactive substances, but their efficiency Also lower.
