In the previous article, Xiaobian introduced the screw vacuum pump to you, and today Xiaobian introduced it to youCentrifugal vacuum pumpWhat is？What are the advantages and disadvantages of centrifugal vacuum pumps？

First, what is a centrifugal vacuum pump？

When the pump shell is filled with liquid, the impeller rotates at high speed, and the liquid produces high speed under the action of centrifugal force。The high-speed liquid passes through the gradually expanding pump housing channel, and the dynamic pressure head is converted into the static pressure head。Care should be taken to prevent cavitation and gas bonding。

Two, the advantages of centrifugal vacuum pump

Compared with the reciprocating pump with the same index, the centrifugal vacuum pump has a simple and compact structure, small size, light weight, fewer parts, convenient manufacturing, low cost, small footprint, so its equipment and maintenance costs are low。

Easy to operate and reliable, easy to adjust and maintain, easy to automate and remote operation。

The maximum flow range of centrifugal vacuum pump is large, and the flow and pressure are stable without fluctuation。

Centrifugal vacuum pump speed is high, can be directly connected with the motor and steam turbine, the transmission mechanism is simple and compact。

Three, the disadvantages of centrifugal vacuum pump

The viscosity of the liquid has a great influence on the performance of the pump。When the viscosity of the liquid increases, the flow rate, head, suction and efficiency of the pump will decrease significantly。

The application of centrifugal vacuum pump is limited under the condition of low flow and high lift。Because the flow channel of the small flow centrifugal pump is very narrow, it is difficult to manufacture and the efficiency is very low。

Before starting the centrifugal vacuum pump, the pump is pumped or the air in the pump is extracted by the vacuum pump。Although it is not necessary to pump self-priming centrifugal pumps before starting, there are still certain limitations in their current use。
