           如今，在烟气净化、气体洗涤或表面清洁的应用中，对立式潜水泵的需求越来越高。为确保可靠的运行以及更快速的清洗过程，这些类型的泵是不可缺少的。

　　　　然而，由于材料的技术特点不同，应用于金属泵的领先技术无法简单的、一尘不变地应用于塑料泵的设计。由于塑料的热弹性有限，离心泵 塑料泵无法和金属泵一样，承受同样高的轴承荷载。

　　　　由于叶轮尺寸的增加，当浸没深度大于2000毫米的单级泵的主轴承和中间轴承要平衡由高速作运的泵产生的高径向力时，试压泵湫枨笠苍黾恿恕Ｕ獗惚┞读巳人懿牧系南拗菩浴?BR>　　　　为此，为研发额定转速1,450转/分钟，即使在连续作业的情况下也能满足操作安全和系统可用性的两级泵系列产品而采用了模块化系统。卫生泵产品采用两个叶轮，排列方式为一个叶轮在另一个后面，如此使得水泵扬程达到了85米。当用于泵送含有固体或具有低润滑特性的液体时，两级泵的轴承耐磨性明显好于快速运转的单级泵。

　　　　另一个重要的优点在于其安装尺寸要小得多—— 深井泵工厂工程的一个重要方面。由于使用了四极驱动系统，该泵运行产生的噪音也极小。　　该两级离心泵的流量可达280立方米/小时，扬程达85米。根据选择材料的不同，适用温度范围从摄氏零下10度到摄氏90度。该泵浸没深度可达4,000毫米。干气密封用于保护轴承，马达安装作为大气轴封。该轴也可通过单动式标准平衡机械密封件来密封。　　轴向力被脂/油浸润滚动轴承所吸收。计量泵多余的径向力被宽大的主轴承所吸收，主轴承由聚四氟乙烯石墨复合材料/陶瓷（PTFE-GF/ceramic）或碳化硅纤维增韧碳化硅（SiC/SiC）制成，取决于泵送介质的情况。

　　　　该泵外壳采用聚丙烯以及聚偏氟乙烯制造。采用玻璃纤维增强或涂层聚丙烯材料的适用于高温应用。　　B80KGKG3两级泵系列为塑料离心泵产品树立了新的标准，为工厂的工程师和操作员进行可靠安全的操作开启了新的局面。

         Now, in the flue gas purification, gas scrubbing or surface cleaning applications, the vertical growing demand for submersible pumps. To ensure reliable operation and faster cleaning process, these types of pumps is indispensable. However, due to the technical characteristics of different materials, leading-edge technology applied to metal pumps Magnetic pumpscan not be simple, Yichen same applied to the plastic pump design. Because the thermal elastic plastic finite, plastic and metal pumps can not pump as high bearing load to bear the same. As the impeller size increase, when the immersion depth of greater than 2000 mm, single-stage pump bearings main bearingsScrew pumps and the middle to balance the high-speed operation of the pump to generate high radial force, the marsh doorpost Li-Cang Shu U unruly strider incite the muddled ┞ Reading had people Yi Mu Nan Ao Bodhisattva bath? BR> To this end, R & D rated speed 1,450 r / min, continuous Zuoye situation even Zai Xia Yenengmanzu operating system security and availability of the two pump series products Er using the modular system. Product uses two impellers, impeller arrangement for a behind in another, so make the water head reached 85 meters. When used for pumping solids or Self-priming pumpsliquids with low lubricating properties, the two pump bearing wear is better than fast running single-stage pump. Another important advantage is its size is much smaller installation - an important aspect of plant engineering. Using a four-pole drive system, the pump running noise is also minimal. The two pump flows up to 280 cubic meters / hour, Suber-water pumpslift up to 85 meters. Select materials according to different application temperature ranging from minus 10 degrees Celsius to 90 degrees Celsius. Immersion depth of the pump up to 4,000 mm. Dry gas seal used to protect the bearings, motor shaft seal installed as the atmosphere. The shaft can be balanced by the standard single-action mechanical seals to seal. Axial force is grease / oil infiltration Rolling absorbed. Extra large radial force is absorbed by the main bearing, main Chemical pumpsbearing graphite composite PTFE / ceramic (PTFE-GF/ceramic) or silicon carbide fiber-reinforced silicon carbide (SiC / SiC) is made, depending on pumping media situation. The pump housing with polypropylene and polyvinylidene fluoride manufacturing. Or coated with glass fiber reinforced polypropylene material for high temperature applications. B80KGKG3 two plastic centrifugal pump series sets a new standard products for plant engineers and operators for reliable and secure operation of opening a new situation.
