When the pump is working, the liquid will produce vapors at the inlet of the impeller due to a certain vacuum pressure, and the vaporized bubbles will exfoliate the impeller and other metal surfaces under the impact movement of the liquid particles, thus destroying the impeller and other metals, at this time the vacuum pressure is called vaporization pressure, and the cavitation margin refers to t...

There are many classifications of centrifugal pumps, which are divided according to different structural characteristics. The specific classification of centrifugal pumps is as follows: Classify according to the number of working impellers. 1. Single-stage pump: that is, there is only one impeller on the pump shaft. 2. Multi-stage pump: that is, there are two or more impellers on the pump shaft, a...

In the process of converting mechanical energy into liquid energy, the centrifugal pump is accompanied by various losses, which are expressed by the corresponding efficiency. The internal loss of centrifugal pump can be divided into mechanical loss, volume loss and hydraulic loss, and the corresponding pump efficiency can also be divided into mechanical efficiency, volumetric efficiency and h...

The speed ratio of a centrifugal pump refers to the frequency at which the pump shaft rotates in a unit time. Public n stands for Enterprise:r/min. The usual centrifugal pump has the increase of 2900r/min or 1450r/min, while the large centrifugal pump has 970r/min or 730r/min. When the speed ratio is fixed, the total flow rate, pump head and output power are all fixed. The speed ratio of centrifug...

What is the working principle of centrifugal pump. Centrifugal pump is widely used in chemical production. Room temperature liquids such as ethylene glycol and water are transported by centrifugal pump. The centrifugal pump is driven by an electric motor, the pump body and the suction pipe are filled with liquid, the motor drives the impeller to rotate at a high speed, and the impeller drives...
