General characteristics of centrifugal pump (1) The flow direction of water along the centrifugal pump is axial suction along the impeller, perpendicular to the axial outflow, that is, the flow direction in and out of 90°. (2) Because the centrifugal pump forms vacuum water absorption by the inlet of the impeller, it is necessary to inject water into the pump and the suction tube before starting, or pump air to discharge the air to form a vacuum, and the pump shell and suction pipe must be strictly sealed, no air leakage, otherwise no vacuum is formed, it will not suck water. (3) Because the inlet of the impeller cannot form an absolute vacuum, the suction height of the centrifugal pump cannot exceed 10 meters, and the loss along the water flow through the suction pipe, the actual allowable installation height (the height of the pump axis from the suction water surface) is far less than 10 meters. If the installation is too high, it will not absorb water; In addition, because the mountain area than the plain atmospheric pressure is low, so the same pump in the mountain area, especially in the high mountain installation, its installation height should be reduced, otherwise it can not suck water. |
