The general characteristics of the centrifugal pump

The general characteristics of the centrifugal pump


(1) The direction of water flowing along the centrifugal pump is sucked in the axial direction of the impeller and flows out perpendicularly to the axial direction, that is, the direction of the inflow and outflow flows at 90° to each other.
(2) Since the centrifugal pump forms vacuum suction through the inlet of the impeller, it is necessary to inject water into the pump and the suction pipe before starting or pumping with a vacuum pump to discharge air to form a vacuum, and the pump casing and the suction pipe must be tightly sealed. Do not leak. Otherwise, it will not form a vacuum. It will not be able to absorb water.
(3) Since the impeller inlet cannot form an absolute vacuum, the water absorption height of the centrifugal pump should not exceed 10 meters, plus the loss of water flowing through the suction pipe, the actual allowable installation height (the height of the pump axis from the suction surface) is much smaller than 10 m. If the installation is too high, it will not absorb water; in addition, because the mountain area is lower than the plain atmospheric pressure, the installation height of the same pump should be reduced when installing in the mountainous area, especially in the high mountainous area. Otherwise, it will not be able to absorb water.
