进口高压锅炉给水泵(欧美进口十大品牌)

英国GRIMM格林进口高压锅炉给水泵 UK GRIMM Imported high pressure boiler feed pump

英国GRIMM格林进口高压锅炉给水泵概述：
          进口高压锅炉给水泵源于英国格林先进技术，主要为200～1200MW火力发电机组配套，输送介质温度≤210℃；泵组配套使用，调整运行，效率高、可靠性好，保证寿命40年。

英国GRIMM格林进口高压锅炉给水泵结构特点：

          进口高压锅炉给水泵为双壳体卧式多级离心泵，刚性转子，临界转速11000r/min；外壳体水平中心支撑，过流部位和配合面堆焊奥氏体不锈钢，提高寿命；内壳体径向部分，采用双平衡鼓对轴向力水力平衡，容积损失较小。
          泵采用径向滑动轴承支撑，双向推力滑动轴承可平衡瞬态残余轴向力；稀油强制润滑。径向轴承均为机加工成型的四油轴承或圆柱轴承，工作状态极佳。润滑油由驱动汽轮机、调整装置(液力偶合器/齿轮箱等)或稀油站提供。
          轴封为流体动力型机械密封，有快装可选。介质自循环经冷却和过滤后冲洗密封动静部分，外设二次回路其冷却。

UK GRIMM Imported high pressure boiler feed pump summary:

           High pressure boiler feed water pump from the British Green advanced technology, mainly for supporting the 200 ~ 1200MW thermal power generating units, transmission medium temperature less than 210 DEG C; pump group matched adjustment operation, high efficiency, good reliability, assurance of 40 years of life.

UK GRIMM Imported high pressure boiler feed pump structure characteristics:       

           High pressure boiler feed pump is a double shell horizontal multistage centrifugal pump, rigid rotor, critical speed 11000r/min; shell level center support, flow area and with the surface welding of austenitic stainless steel, improve the life of the inner shell; radial part adopts the double balanced drum on the axial force of hydraulic balance, small volume loss.

        The pump is supported by radial sliding bearings, and bidirectional thrust bearings can balance the transient residual axial forces. Radial bearings are machined four oil bearings or cylindrical bearings, in excellent working condition. The lubricating oil is supplied by a drive turbine, an adjustment device (hydraulic coupling / gearbox, etc.) or a thin oil station.

        Shaft seal is fluid power type, mechanical seal, quick installation optional. The medium self circulation, after cooling and filtering, seals the static and dynamic parts, and the peripheral two circuit is cooled.
