德國REXROTH葉片泵信息
REXROTH葉片泵均為臥式、單泵殼構(gòu)造的離心泵。選用特殊的卡箍夾緊泵體與泵蓋，REXROTH泵的吐出口方向可在360度的任何一個方位，裝置使用方便。砂泵的軸承組件選用圓筒式構(gòu)造，便于調(diào)整葉輪與泵體之間的空隙，REXROTH修理時可全體撤除。軸承選用油脂光滑。砂泵的軸封方法有填料密封、付葉輪密封、機(jī)械密封。砂泵流道寬暢，REXROTH汽蝕性能好，效率高，耐磨蝕。傳動方法主要有V型三角帶傳動、彈性聯(lián)軸器傳動、輪減速箱傳動、REXROTH液力偶合器傳動、變頻驅(qū)動裝置，可控硅調(diào)速等。過流部件原料選用高硬度的耐磨合金鑄鐵。然后發(fā)動離心泵，葉輪疾速滾動，REXROTH葉輪的葉片唆使液體滾動，液體滾動時依托慣性向葉輪外緣流去，一起葉輪從吸入室吸進(jìn)液體，在這一過程中，REXROTH葉輪中的液體繞流葉片，在繞流運(yùn)動中液體效果一升力于葉片，反過來REXROTH葉片以一個與此升力大小相等、方向相反的力效果于液體，這個力對液體做功，使液體得到能量而流出葉輪，這時REXROTH液體的動能與壓能均增大。REXROTH葉片泵依托旋轉(zhuǎn)葉輪對液體的效果把原動機(jī)的機(jī)械能傳遞給液體。由于REXROTH離心泵的效果液體從葉輪進(jìn)口流向出口的過程中，其速度能和壓力能都得到添加，被REXROTH葉輪排出的液體通過壓出室，大部分速度能轉(zhuǎn)換成壓力能，然后沿排出管路運(yùn)送出去，這時，REXROTH葉輪進(jìn)口處因液體的排出而構(gòu)成真空或低壓，吸水池中的液體在液面壓力(大氣壓)的效果下，被壓入REXROTH葉輪的進(jìn)口，于是，旋轉(zhuǎn)著的REXROTH葉輪就連續(xù)不斷地吸入和排出液體.
