英國(guó)GRIMM格林進(jìn)口高壓鍋爐給水泵 UK GRIMM Imported high pressure boiler feed pump

英國(guó)GRIMM格林進(jìn)口高壓鍋爐給水泵概述：
          進(jìn)口高壓鍋爐給水泵源于英國(guó)格林先進(jìn)技術(shù)，主要為200～1200MW火力發(fā)電機(jī)組配套，輸送介質(zhì)溫度≤210℃；泵組配套使用，調(diào)整運(yùn)行，效率高、可靠性好，保證壽命40年。

英國(guó)GRIMM格林進(jìn)口高壓鍋爐給水泵結(jié)構(gòu)特點(diǎn)：

          進(jìn)口高壓鍋爐給水泵為雙殼體臥式多級(jí)離心泵，剛性轉(zhuǎn)子，臨界轉(zhuǎn)速11000r/min；外殼體水平中心支撐，過(guò)流部位和配合面堆焊奧氏體不銹鋼，提高壽命；內(nèi)殼體徑向部分，采用雙平衡鼓對(duì)軸向力水力平衡，容積損失較小。
          泵采用徑向滑動(dòng)軸承支撐，雙向推力滑動(dòng)軸承可平衡瞬態(tài)殘余軸向力；稀油強(qiáng)制潤(rùn)滑。徑向軸承均為機(jī)加工成型的四油軸承或圓柱軸承，工作狀態(tài)極佳。潤(rùn)滑油由驅(qū)動(dòng)汽輪機(jī)、調(diào)整裝置(液力偶合器/齒輪箱等)或稀油站提供。
          軸封為流體動(dòng)力型機(jī)械密封，有快裝可選。介質(zhì)自循環(huán)經(jīng)冷卻和過(guò)濾后沖洗密封動(dòng)靜部分，外設(shè)二次回路其冷卻。

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.
