1. The key to the installation technology of fluoroplastic centrifugal pump is to determine the installation height (suction distance) of fluoroplastic centrifugal pump, which refers to the vertical distance between the water source surface and the center line of chemical centrifugal pump impeller, which should not be confused with the allowable vacuum suction height. The allowable vacuu...

Before starting the centrifugal pump, it should first be filled with water to discharge the air from the pump shell. From the working principle of the centrifugal pump, when the impeller rotates, the water is thrown to the outer edge of the impeller by the centrifugal force, the vacuum is formed at the center of the impeller, and the water is sucked into, forming the continuous working proces...

In the chemical industry, the use of centrifugal pumps is very common. Centrifugal pump generally uses motor to drive operation, which is easy to use, safe, fast and so on. It is an indispensable and important power provider in everyone's production and work. In the process of using, a lot of motors will have serious heating phenomenon, but often do not know how to solve it, and what is more serio...

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...

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...

What is the function of the leakage reducing ring of the centrifugal pump? There is a rotating gap at the joint between the outer edge of the suction inlet of the centrifugal pump impeller and the inner wall of the pump shell, and there is a high and low pressure area on both sides of the gap. If the clearance is too large, the high-pressure water in the pump housing will leak into the l...

When the stainless steel centrifugal pump starts up, if there is gas in the pump, because the density of the air is small, the centrifugal force produced is also relatively small, at this time the center of the centrifugal impeller can only produce a relatively small negative pressure, and can not absorb the liquid, it will produce the centrifugal impeller idling, destroying the stainless steel ce...

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...
