Common Methods Of Diverting Water From Multistage Centrifugal Pumps

Released on Jan. 28, 2019

Multistage Centrifugal Pump should be filled with water in the pump and intake pipe before starting, otherwise the pump can not lift water. When a multistage centrifugal pump starts, it will not be able to produce water, which is often caused by the fact that the air in the pump is not discharged and the water is not filled. Then, what are the common methods of diverting water by multi-stage centrifugal pumps? See the details.

Common methods of multi-stage centrifugal pump irrigation and water diversion:

1. Water Filling and Irrigation Method

For multi-stage centrifugal pumps with low water quality requirements, or other material-liquid pumps with little influence on the transport medium, tap water can be used to fill and irrigate, which is very convenient.

2. Suction sucking method

This method mainly uses the pumping equipment to suck up the liquid by sucking out the air in the multi-stage centrifugal pump and suction tube. The pumping equipment can be operated by hand press and motor vacuum pump (usually water ring vacuum pump). The suction port of the vacuum pump is well connected to the highest part of the pump or the drainage pipe in order to extract all the gas in the pump.

3. Backflow Filling and Irrigation Method

The backflow filling system uses the accumulated liquid in the high trough on the discharge side to recharge. When this method is adopted, the artificial quasi-pump is used to start the first time.

4. Manual Pump Filling Method

As one of the reciprocating volume pumps, manual pumps are widely used in rural areas of China. Farmers can use their own manual pumps as vacuum pumps to fill centrifugal pumps, which is convenient and economical.

The most common usage is to install the manual pump on the pumping hole of the Centrifugal Pump or on the intake pipeline near the pump for pumping air and water, so as to make it a tool for filling water when the centrifugal pump is turned on, thus saving the bottom valve of the intake pipeline of the pump, reducing energy consumption and improving the efficiency of the pump device.
