不可忽略对中开泵可靠性方面的要求，总之通过我们的努力要获得一款效率高汽蚀性能好，运行可靠稳定的好泵。中开泵主要适用于输送不含固体颗粒的介质。因此这种泵可以在石油，化工以及电力等行业进行应用，比如说在石化中延迟焦化，火电厂中的中型锅炉给水等。这种类型的泵在维护方面非常的方便，因此在相关的行业中得到了广泛的应用。由于泵内的各种损失泵的有效功率总是小于轴功率，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。

本系列泵是单级、双吸、水平中开式离心泵，适用于汲送清水和无腐蚀性的液体。介质温度80℃。轴承体通人冷却水后，可输送130℃以下的热水。改变密封环、轴套和叶轮的材质，可以输送含有泥沙的浑水。改变承压零件的材质，可以提高泵的进口压力.泵的轴封一般采用软填料密封，如有特殊要求，也可改装机械密封。从电机方向看泵，泵为逆时针旋转，按用户要求，也可改为顺时针旋转。jdhuiquan4.13

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.

根据水泵行业规定，Sh型与S型两大系列中开泵并存，直至统一设计出新型泵代替这两个系列时为止。本产品主要用于工厂、矿山、城市、电站给水农用排涝灌溉、各种水利工程用泵和采暖空调系统等场合
