Liaoning Star Pump Co., Ltd. after many years of experience gained experience to share with you: the key technology of centrifugal pump installation is to determine the pump installation height. The installation height refers to the vertical distance from the water surface of the water source to the center line of the pump impeller. It can not be confused with the allowable suction height and is measured at 1 standard atmospheric pressure and at a water temperature of 20 degrees Celsius. It does not consider the condition of the water flow after the water supply pipe is matched. The pump installation height should be allowed to suck vacuum height deducted after the head of the suction pipe loss, the remaining part of the value, it is necessary to overcome the actual terrain water absorption height. Pump installation height can not exceed the calculated value, otherwise, the pump will not pump water. In addition, the impact of the calculated value is the size of the suction pipe lift loss lift, it is appropriate to use the shortest pipe layout, and try to install less elbow and other accessories, but also consider the appropriate with some larger diameter pipes to reduce the flow rate within the pipe. It should be noted that the pump installation site height and water temperature is different from the test conditions, such as the local altitude of 300 meters or more than the pumping water temperature exceeds 20 degrees Celsius, the calculated value to be amended. Ie atmospheric pressure at different elevations and saturated vapor pressure above 20 degrees Celsius. However, when the water temperature is below 20 degrees Celsius, the saturated steam pressure is negligible. From the pipe installation technology, the suction pipe requires strict sealing, can not leak, leakage, otherwise it will undermine the pump inlet of the vacuum, so that the water pump to reduce the amount of water is not even pumping in serious cases. Therefore, we should conscientiously do the work of the interface of the pipeline to ensure the construction quality of pipeline connection.
