Hbzhan content introduction: It is the use of suction equipment to extract the air in the centrifugal pump and suction pipe, the liquid sucked up. Pumping equipment can be used hand presses and motorized vacuum pumps (usually water ring vacuum pump), vacuum pump suction port really connected to the highest part of the pump or drain tube can pump all the gas.
<br> <br> downstream centrifugal pump unit 1. Water filling method filling method using this method in many cases, as long as it is lower than the position of the pump suction sump (groove) level, called reperfusion. Because the liquid is always stored in the pump during installation, the pump does not need to be filled separately. When in use, inhale the pipeline to install the valve for the overhaul of the pump. This valve should use a small resistance valve, cocks, etc., at the same time do not forget to open the water filling method 2. It <br> <br> centrifugal pump for less demanding quality, with tap water or irrigation pump before the pump delivery start Other material liquid pumps with little influence on the medium can be filled with tap water, which is very convenient.
3. Method <br> <br> evacuation sucking suction device which is the use of a centrifugal pump and an air intake in the tube deprived, sucking up the liquid. Air extraction equipment can be used hand presses and motorized vacuum pumps (usually water ring vacuum pump), vacuum pump suction port is really connected to the highest part of the pump or the drain tube can pump all the gas in the pump. For the water quality requirements of the centrifugal pump is not high , Or other liquid pumps with tap water irrigation pump that have little effect on the transmission medium, can be filled with tap water, very convenient.
4. <br> <br> back filling method using reverse flow filling system liquid reservoir discharge side of the header tank proceeds to back filling, when using this method, starting the first start doing job quasi pump
