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.

故效率总是小于1的。目前国内中开泵中多数型号的效率一般在70-80％左右，少数大流量型号的效率在90%左右。影响中开泵效率的主要原因在于泵内存在的能量损失，这些损失主要是机械损失，水力损失和容积损失。机械损失主要是叶轮外表面与液体的磨擦损失（即圆盘摩擦损失）以及离心泵轴承，轴封上的摩擦损失，水力损失主要是液体在泵内运动速度和方向的变化引起的冲击损失。中开泵效率是指泵的有效功率和轴功率的比值旋涡损失等，液体与泵内各流道壁面的磨擦损失以及液体运动的内部磨擦损失，容积损失主要是泵内高压液体向低压区泄露回流造成的损失，包括密封环泄漏损失，平衡机构泄漏损失和级间泄漏损失。通过不同可以使中开泵的效率和汽蚀性能得到很好的提升当然在进行效率和汽蚀性能改造的同时。
