Chemical centrifugal pump working principle is filled with water in the pump case, the centrifugal force produced by the rotation of the impeller, the impeller, the water in under the action of centrifugal force to jilt to peripheral flow into the pump shell, so the impeller center reduced pressure, the pressure is lower than the water tube, under the action of water on the pressure difference by suction tank into the impeller. In this way, the pump can continuously absorb water and continuously supply water.
Besides the role of impeller in chemical centrifugal pump, the role of spiral pump shell is also very important. The fluid from the impeller has a larger function when it comes out of the impeller, which is collected in the spiral pump shell and turns kinetic energy into pressure energy in the subsequent diffusion tube. Health level self-priming pump.
Compared with other types of pump, chemical centrifugal pump has simple structure, is not easy to wear, stable operation, low noise, uniform water, convenient adjustment, high efficiency, etc. So the chemical centrifugal pump has been widely used.
Chemical centrifugal pump can adapt to the chemical process needs, there are many kinds of development so far, different functions, such as ceramic pump, acid pump and other kinds of pump products. Because chemical pump is applied in chemical industry, it is necessary to convey corrosive chemical medium, and the flow and lift of centrifugal pump should be stable to ensure efficient and reliable operation of the pump.
The chemical centrifugal pump can transport the critical state of the liquid. A liquid in a critical state usually vaporizes when the temperature increases or the pressure decreases. In order to avoid the failure of mechanical seal, packing seal, labyrinth seal and other dry friction due to the vaporization of the liquid, such chemical pump must have a structure that fully eliminates the gas that occurs in the pump.
Corrosion - resistant chemical pump delivery medium, including raw materials, reaction intermediates are often more corrosive media. This requires the material of the pump to choose proper and reasonable, ensure the safe, stable, long life operation of the pump. Chemical centrifugal pump can transport high temperature, low temperature medium, if the material selection of the pump wear resistant manganese steel, ceramics, cast iron, etc., and selects the scour resistance of titanium, manganese steel, etc. Also has the characteristics of wear resistance, resistance to erosion.
The chemical centrifugal pump is reliable, and the long period operation is stable. The reliability of operation is critical to chemical production. If the pump frequently fails, it will not only cause frequent production shutdown, but also affect the production and economic benefits, and sometimes may cause accidents in chemical systems. For chemical pump is the most important is no leak, mostly chemical pump medium inflammable, explosive, poisonous and harmful liquid, once the leak will seriously pollute the environment, endanger personal safety and health of body and mind of the worker.
It can be seen that there are many types of chemical pumps, different materials and different structures of pumps are different for use, and chemical centrifugal pumps can adapt to the chemical process needs. Therefore, you should choose the appropriate chemical pump according to the actual situation and reduce the problems in operation.
