The main installation of pipeline centrifugal pump is to measure the installation height of the pump. This height refers to the vertical distance of the center line of the surface water pump impeller and should not be confused. The information on the pump product shows that vacuum suction is allowed. The vacuum height refers to the value of the inlet part of the vacuum pump and is measured under standard conditions. It does not consider whether the water pipe supports the future water environment and the allowable installation height of the pump, but it needs to consider that it excludes the rest of the value of the suction pipe head after the loss. The installation height of the pump cannot exceed the calculated value; otherwise, the pump cannot emerge. In addition, the value of the calculated value affects the head loss of the suction pipe resistance. Therefore, the shortest pipe layout should be adopted, and the elbow and other fittings should be minimized, and appropriate large-diameter pipes can also be considered to reduce the pipe flow rate.
It should be pointed out that the installation location of the pipeline centrifugal pump and the water temperature are different test conditions. For example, if the local altitude is 300 meters or the temperature of the injected water is more than 20 degrees Celsius, the calculated value will be modified. This is atmospheric pressure and saturated steam pressure at altitudes in excess of twenty degrees Celsius. However, when the water temperature is less than twenty degrees Celsius, the saturated vapor pressure can be ignored.
Suction piping From the point of view of pipeline installation technology, there is a strict stringency and no leakage of water and gas. Otherwise, the degree of vacuum at the suction inlet of the pump will be damaged. Reduce the amount of water pumped out and it will be occupied in serious cases. Therefore, we must conscientiously improve the pipeline interface and ensure the construction quality of pipeline connections.
Installation Note:
(1) The installed base surface must be smooth, clean and capable of withstanding the corresponding loads;
(2) Need a fixed place to use the anchor bolt;
(3) Install the pump vertically, the anchor bolt must have a certain degree of strength;
(4) To be installed vertically, it must be located above the water pump;
(5) Grasp the key technology of centrifugal pump installation when fixed on the wall;

Gas Confinement
When air enters the air pump housing, less centrifugal force will be generated because the air density is much less than the density of the liquid. Therefore, the above tank level and the pressure at the pump inlet cannot activate the pressure pump. The liquid will not have the ability to self-prime the centrifugal pump, so that the centrifugal pump can not transport the liquid in time. This phenomenon is called “gas restriction phenomenonâ€. . In order to fill the pump with liquid, a valve is usually installed at the bottom of the suction pipe installation area. This valve is used to cause solid material to enter the pump impeller to cause damage or interfere with the normal operation of the pump.
