In the event of a major failure, the entire water treatment process will be paralyzed, bringing great inconvenience to the people's lives and production. According to the current analysis of the operation of the pump in the S series, the common faults are: The impeller has been subjected to surface corrosion in the sewage for a long time, the early fatigue fracture of the blades, the wear of the pump body overflow parts, the bending of the pump shaft, the burnout of the motor and the bearing, etc. It is very important to study the operation Safety, through the research of this content, not only improve the safety of the pump, but also improve its service life. And in the process of water treatment work, the use of the system is often changed, if not in accordance with the needs to be met, will affect the normal operation of production, resulting in greater waste. In order to manage effectively, it is necessary to carry out remote monitoring and field control of production system, and in order to improve production efficiency and safety, it is also necessary to detect the key parts of the pump in the S series. Thus, the research of automatic control technology is an important technology development trend.

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。
