What is About Centrifugal Pump?

Centrifugal pump is a kind of machinery used for pumping water through the 
centrifugal movement, which is composed of pump casing, impeller, shaft, pump frame and other components. The pump should be filled with water before starting it, then  the impeller can whirl the water in the pump at high speed, which will drive the  water make centrifugal movement , and at the same time throw out the water and is pressed into the pipes. After the water being thrown out, he pressure will decrease near the impeller, which cause a low pressure area from around the shaft.

The pressure formed here is lower than the atmosphere pressure, so the water outside can rush to open the bottom valve and flow into the pump through the inlet.  However, the water that has flown into pump will be thrown out again with whirling  impeller and pressed into outlet pipe. As long as the impeller can be driven at high speed by power, the water will be pumped from the lower area to the high area  continuously.

Comparing with other pumps, centrifugal pump has many distinctive advantages: High speed, small size, light weight, high efficiency, high traffic flow, simple 
structure, stable performance, easy operation and maintenance; The only one 
disadvantage of the pump is that the liquid must be filled with pump before starting it.

After finding out its working principles and features, the next step is to know how to operate it. There are some important points that you should keep in your mind  when operating it: prohibit running without water and don't reduce flow rate by adjusting inlet; Do not use too much lubricant; Keep maintenances on it every six months.
