The multi-stage pump is a kind of centrifugal pump. It also relies on the rotation of the impeller to obtain the centripetal force, thus the material. When the gas density reaches the working range of the mechanical vacuum pump, it is pumped out, so as to gradually obtain a high vacuum.
Multistage pump can be used in many industries such as petroleum, chemical industry, machinery, mine, light industry, medicine and food. In many processes of industrial consumption, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture return and vacuum degassing, multistage pumps are widely used. It can pump out inflammable and explosive gas as well as dust and water containing gas. Therefore, the application of water ring pump is increasing day by day.
Multistage pump is a kind of centrifugal pump which is composed of the inlet and outlet section and the middle section through the pull rod. Its output water pressure can be very large, and it also relies on the rotation of the impeller to obtain the centripetal force, thus the material. When the gas density reaches the working range of the mechanical vacuum pump, it is pumped out, so as to gradually obtain a high vacuum.
The multi-stage pump is a centrifugal pump which can change the volume of the pump cavity to complete suction, contraction and exhaust.
