清水灌溉泵@桥西清水灌溉泵@清水灌溉泵8SH-9

矿山，城市给排水，电站，农田排灌及各种水利工程。S系列中开泵工作原理：1，许用工作压力为，即泵入口压力+泵扬程≤。根据泵壳承受的zui大压力，泵体和泵盖材质采用灰口铸()。介质：温度≤105℃的清水或物理化学性质类似清水的其它液体(固体颗粒80mg/L)。采用油脂润滑的封闭式滚动轴承，维护简单，运行时间长。(2)，配备恒定油位的油杯，也可用稀油润滑。(3)，中开泵选用进口(SKF，NSK，NTN)高质量轴承，运行平稳，澡音低，使用寿命长。结构紧凑，稳定性好。该型泵为泵壳中开结构，进出口均在泵体上，检修时只需吊出泵盖，转子部件便可移出进行检修作业，而不需拆卸管路，十分方便。根据需要电动机(驱动机)可以在左端也可在右端。

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

清水灌溉泵@桥西清水灌溉泵@清水灌溉泵8SH-9

Thus the centrifugal force is generated, under the action of centrifugal force, the liquid is dumped along the Blade Runner to the impeller outlet, and the liquid is collected and fed into the discharge tube through the worm shell. The liquid obtains energy from the impeller, increasing the pressure energy and speed energy, and relies on this energy to transport the liquid to the place of work. When an impeller does not allow the liquid to obtain sufficient energy, multiple impellers can be used in series or in parallel to work on the fluid. At the same time that the liquid is dumped to the impeller outlet, a low pressure is formed at the center of the impeller Inlet, and the pressure difference is generated between the liquid in the suction tank and the center of the impeller, and the liquid in the suction tank is continuously operated into the impeller under the action of this pressure difference. In this way, the impeller in the rotation process, one side of the constant liquid, while constantly giving the liquid with a certain amount of energy, the liquid discharge, so that the centrifugal pump work continuously. The medium-open pump is mainly composed of pump body, pump cover, sealing ring and rotor parts. Rotor parts are mainly composed of shafts and impeller mounted on the shaft, impeller retaining sleeve.

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

[二]性能范围：
