Side can be started. Pump commissioning should meet the following requirements: The pump should be in the specified speed and operating range of operation, continuous commissioning time should not be less than 30min, the pump water supply should be normal, water temperature and water supply pressure should be in line with the requirements of the manufacturer; The temperature rise of the bearing should not be higher than 30 ℃, and the connection should be strict. 4 No leakage phenomenon, there should be no abnormal sound and vibration in operation, after the commissioning, should be released in the pump water, and then use water to rinse the pump clean. S series of open pumps can be basically supplied to factories, cities, power stations, water conservancy projects and so on can be used as drainage or feed pumps, but also for farmland irrigation. For the transport of water without solid particles or physical, chemical properties similar to water other liquids, the transmission of the medium temperature of 0℃~80℃, allowing the import pressure. In the water treatment industry, the S-series Open pump is an extremely important equipment. The Operation safety of the open pump in the S series directly affects the normal operation of the water treatment process.

故效率總是小于1的。目前國內中開泵中多數型號的效率一般在70-80％左右，少數大流量型號的效率在90%左右。影響中開泵效率的主要原因在于泵內存在的能量損失，這些損失主要是機械損失，水力損失和容積損失。機械損失主要是葉輪外表面與液體的磨擦損失（即圓盤摩擦損失）以及離心泵軸承，軸封上的摩擦損失，水力損失主要是液體在泵內運動速度和方向的變化引起的沖擊損失。中開泵效率是指泵的有效功率和軸功率的比值旋渦損失等，液體與泵內各流道壁面的磨擦損失以及液體運動的內部磨擦損失，容積損失主要是泵內高壓液體向低壓區泄露回流造成的損失，包括密封環泄漏損失，平衡機構泄漏損失和級間泄漏損失。通過不同可以使中開泵的效率和汽蝕性能得到很好的提升當然在進行效率和汽蝕性能改造的同時。
