我国农村幅原广阔，每年农村都需要大量的泵，一般来说农用泵占泵总产量一半以上。中开泵在建筑领域提供楼宇自动给排水，增压锅炉给水，疏竣，无负压给水，暖通空调，消防设备及其它通用设备。电力领域提供灌溉，排水，引水工程，自来水工程，发电厂除灰，冷凝水，循环水，锅炉供水等设备配套服务。卧式双吸中开泵在环保领域中提供污水处理，绿化灌溉，引水，配水，土壤改良或排洪水等。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。双吸中开泵在水利。由于泵内的各种损失泵的有效功率总是小于轴功率。

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

If you spray oil outward, you should stop and check immediaby. The purchase of mechanical seals at different prices has a significant impact on their quality. Take quality control measures mechanical seal before leaving the factory must do sealing perbance test, and have a certificate. Mechanical seal after long-term operation, so that the dynamic ring and static ring wear, spring and shaft rust wear, sealant ring wear, aging, debation, etc., can cause sealing leakage, must repair or replace new parts. The sealing surface of the dynamic ring and static ring shall not have cracks, corners, scratches, hemp points, flying edges and partial grinding, scratches, hemp points can not run through the entire sealing end surface. If the fixed static and dynamic ring is used, the height of the convex of the static and dynamic ring is not less than 3mm, and the height of a single convex is not less than lmm, so as not to affect the heat dissipation. 3 Dynamic ring After installation should be guaranteed to move flexibly on the shaft, the dynamic ring pressure on the spring should be able to bounce back freely, to maintain the vertical and parallel of the static and dynamic ring. Reasonable selection of medium-open pump, is to consider the pump unit and pumping station investment and operating costs, such as comprehensive technical and economic indicators.

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
