详细介绍高压50bar多级离心泵叶轮雷竞技官网最新版

人们所说的多级离心泵就是有多个叶轮的离心泵。雷竞技官网最新版叶轮的主要作用是增加水压。等待气体从真空泵中吸出后，整个工作环境就变成真空。雷竞技官网最新版多级泵依靠容积变化来实现吸入、压雷竞技官网最新版缩和排气，所以它是一种可变化的离心泵。

它的作用是收集叶轮甩出的液体，降低液体的流量，并将部分速度能头转换为压力能头，然后均匀地引入下一级或通过扩散器排出。

　　The role of the guide vane is the same as that of the volute, and it is mostly used in segmented multi-stage pumps. In a multi-stage centrifugal pump, the guide vane is installed in the middle section with a partition.

　　 guide vanes can be divided into radial guide vanes and flow channel guide vanes according to their structure. The forward guide vane and the reverse guide vane of the flow channel guide vane are cast together, and there is a continuous flow channel in the middle, so that the liquid can flow in the continuous flow channel, which is not easy to form dead angles and sudden diffusion, the speed change is relatively uniform, and the hydraulic performance is better. , But the structure is complex and the manufacturing process is poor.

　　 The guide vanes are mostly used in the reverse flow of hydraulic machinery, such as movable guide vanes of hydraulic turbines, fixed guide vanes, and guide vanes in water pumps. Their role is to produce return (note: fixed guide vanes can also produce partial return), and many academic circles may not accept this function of fixed guide vanes.
