1. Downstream filling method tap water filling method
Centrifugal pump device in many occasions the use of this method, it as long as the pump is positioned below the suction tank liquid level, the so-called perfusion. Because this installation has been preserved in the pump liquid, so no need to fill the pump when the pump. When used in the pipeline must be installed in the valve, so that the pump overhaul. This valve should be selected valve, cock small resistance, at the same time do not forget in the pump before starting to open it
2. Tap water filling method
For the water quality requirements are not high centrifugal pump, or with tap water pump on the delivery of the medium has little effect on the other liquid pump, can be used for water filling, very convenient.
3. Suction suction method
It is the use of pumping equipment will be the centrifugal pump and suction pipe in the air pumping out, the liquid suck up. Pumping gas equipment available hand press and mechanical vacuum pump (often for water ring vacuum pump), vacuum pump pumping port good connection in the highest parts of the pump or drain pipe to smoke to the gas within the pump
The water quality requirements are not high centrifugal pump, or with the tap water pump on the transport medium has little effect on other material liquid pump, can be used for water filling, very convenient.
4. Back filling method
Backflow filling irrigation system by using the discharged liquid accumulated in the high side groove to back filling, using this method when first starting to use artificial quasi pump it.
