1. Chemical centrifugal pump installation technology is the key to determine the installation of chemical centrifugal pump height (ie suction). This height refers to the vertical distance from the water surface of the water source to the centerline of the chemical centrifugal pump impeller. It can not be confused with the allowable suction vacuum height. The allowable suction vacuum height indicated on the product manual or nameplate of the chemical centrifugal pump means the chemical centrifugal pump intake cross section On the vacuum value, but also at 1 standard atmospheric pressure, the water temperature of 20 degrees Celsius, the test was measured and measured. It does not consider the condition of the water flow after the water supply pipe is matched. The chemical centrifugal pump installation height should be allowed to suck the vacuum height deducted after the loss of suction pipe lift, the remaining part of the value, it is necessary to overcome the actual topography absorbent height. Chemical centrifugal pump installation height can not exceed the calculated value, otherwise, the chemical centrifugal pump will not pump water.
2. The impact of the calculated value is the size of the suction pipe lift loss lift, it is appropriate to use the shortest piping layout, and try to install elbows and other accessories, but also consider the appropriate larger diameter pipes to reduce the flow rate within the tube.
3. It should be noted that the chemical centrifugal pump installation site elevation and water temperature is different from the test conditions, such as the local elevation of 300 meters or 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.
4. From the pipeline installation technology, water pipes require strict sealing, can not leak, leakage, otherwise it will undermine the chemical centrifugal pump intake at the vacuum, the chemical centrifugal pump to reduce the amount of water, even in severe pumping Sheung Shui. Therefore, we should conscientiously do the work of the interface of the pipeline to ensure the construction quality of pipeline connection.
