When we choose a pipe centrifugal pump corresponding to the working conditions, but the installation process can not be ignored, the installation will directly affect the efficiency of the pipeline centrifugal pump. Now I will introduce the key technology of pipeline centrifugal pump installation. 1, the pipeline centrifugal pump installation technology is the key to determine the installation of the pump height (suction). This height refers to the vertical distance from the water surface of the water source to the center of the pump impeller, which can not be confused with allowing the vacuum to be sucked up. Pump product manual or nameplate marked on the suction allows the vacuum height refers to the pump inlet section of the vacuum value, but also at 1 standard atmospheric pressure, the water temperature of 20 degrees Celsius, the test was measured and determined. 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 loss of suction pipe head, 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. 2, Pipeline centrifugal pump installation site elevations and water temperature is different from the test conditions, such as the local elevation of 300 meters above 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. 3, from the pipe installation technically, the suction pipe requires strict sealing, can not leak, leakage, otherwise it will undermine the pump inlet 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. When we install the pipeline centrifugal pump, we should take full account of various factors, according to different environments for different adjustments, the only way to better improve the efficiency of pipeline centrifugal pump. Achieve the desired effect.
concentric reducer: the center of the size is on the same line. forming process: suppress necking, expanding suppress or necking plus expanding repression. some sizes can also be stamping. Forming process: suppress necking, expanding suppress or necking plus expanding repression, stamping.
