Installing technical key
Centrifugal pump installation technology key is sure pump installation height. This height refers to water pump impeller water to the centerline of the vertical distance, it can not confuse with allowed vacuum suction pump height, water pump nameplate or product manuals on labeled allowed smoke vacuum pump inlet section height refers to the vacuum values and under 1 standard atmospheric pressure. 20 degrees Celsius temperature circumstance, test and measurement. It does not take into consideration of the suction piping supporting water conditions. And the pump mounting height should be allowed on vacuum suction height deducting suction piping loss head later, that part of the remnant numerical, it must overcome terrain bibulous height. Pump installation height cannot exceed calculation values, otherwise, the pump will not pump water. In addition, affect the size of the calculated value is bibulous pipeline resistance losses head, therefore, appropriate using the shortest piping layout, and try to short-ship elbow and other accessories, also can consider appropriate with larger diameter pipes, in order to reduce tube velocity.
It should be pointed out that the pump installation site elevation and water temperature is different from the test conditions, such as local altitude 300 meters above or pumping water more than 20 degrees Celsius, the calculated value needs to amend. Namely different elevations elevation in atmospheric pressure and higher than 20 Celsius temperature of saturated steam pressure. However, water temperature is below 20 degrees, the saturated steam pressure is negligible. Centrifugal pump installation technology key is sure pump installation height.

From piping installation technology, suction piping requirements have strict sealing, cannot leak gas, leak water, otherwise will damage the vacuum pump inlet place, make water pump water yield decreased, serious even can not pump water. Therefore, careful doing pipeline interfaces, guaranteeing the quality of the construction of the pipe connection.
