REXROTH液(ye)(ye)(ye)壓(ya)泵是一種葉片泵，依靠旋轉(zhuan)的(de)(de)葉輪在旋轉(zhuan)過程中，由于葉片和液(ye)(ye)(ye)體(ti)(ti)的(de)(de)相互(hu)作用，葉片將(jiang)機械能傳給液(ye)(ye)(ye)體(ti)(ti)，使液(ye)(ye)(ye)體(ti)(ti)的(de)(de)壓(ya)力能增加，達到輸送液(ye)(ye)(ye)體(ti)(ti)的(de)(de)目的(de)(de)。REXROTH液(ye)(ye)(ye)壓(ya)泵的(de)(de)啟動要注意四點：

　　①REXROTH液壓泵在一定轉速(su)下所產生(sheng)的(de)(de)揚(yang)程有一限定值。工作點(dian)流量和軸功率取(qu)決(jue)于(yu)與泵連接的(de)(de)裝置系統的(de)(de)情況(kuang)(位差、壓力差和管路損失)。揚(yang)程隨流量而改(gai)變。

　　②工作穩定(ding)，輸(shu)送連續(xu),流(liu)量和壓力(li)無脈(mo)動。

　　③一般無自(zi)吸(xi)能力,需要將(jiang)泵先(xian)灌滿(man)液體或將(jiang)管路抽成真空后才能開始工作。

　　④REXROTH液壓泵在排出(chu)管路(lu)閥門(men)關閉狀(zhuang)態(tai)下(xia)(xia)啟動，旋(xuan)渦泵和軸(zhou)流泵在閥門(men)全開狀(zhuang)態(tai)下(xia)(xia)啟動，以(yi)減少啟動功率。

REXROTH液壓泵暖泵

　　輸送高(gao)溫(wen)(wen)液體(ti)的(de)(de)多級REXROTH液壓泵(beng)，如電廠的(de)(de)鍋(guo)爐給(gei)水泵(beng)，在啟(qi)動(dong)(dong)前必須(xu)先暖泵(beng)。這(zhe)是(shi)因(yin)為給(gei)水泵(beng)在啟(qi)動(dong)(dong)時，高(gao)溫(wen)(wen)給(gei)水流過泵(beng)內，使泵(beng)體(ti)溫(wen)(wen)度從(cong)常溫(wen)(wen)很快升高(gao)到100～200℃，這(zhe)會引起泵(beng)內外和(he)各部件之(zhi)間的(de)(de)溫(wen)(wen)差，若沒有足夠(gou)長的(de)(de)傳熱時間和(he)適當(dang)控制溫(wen)(wen)升的(de)(de)措施，會使泵(beng)各處膨脹不均(jun)，造成泵(beng)體(ti)各部分變形、磨損、振動(dong)(dong)和(he)軸承抱軸事故(gu)。
