REXROTH液壓泵是一種葉(xie)(xie)片(pian)泵，依靠(kao)旋轉的(de)葉(xie)(xie)輪(lun)在旋轉過程中，由于葉(xie)(xie)片(pian)和液體的(de)相互作用，葉(xie)(xie)片(pian)將(jiang)機械能傳給液體，使液體的(de)壓力能增(zeng)加，達到(dao)輸送液體的(de)目的(de)。REXROTH液壓泵的(de)啟動要注意四(si)點：

　　①REXROTH液(ye)壓(ya)泵在(zai)一(yi)定(ding)(ding)轉速下所產生(sheng)的揚(yang)(yang)程(cheng)有一(yi)限定(ding)(ding)值。工(gong)作點(dian)流量(liang)和軸功率取決(jue)于與泵連接的裝(zhuang)置系統(tong)的情(qing)況(位(wei)差、壓(ya)力差和管路損失(shi))。揚(yang)(yang)程(cheng)隨流量(liang)而改變(bian)。

　　②工作穩定，輸(shu)送(song)連(lian)續,流量和壓(ya)力無脈動。

　　③一般(ban)無自吸能力,需要將泵(beng)先灌滿(man)液(ye)體或將管路抽成真空后(hou)才能開(kai)始(shi)工作。

　　④REXROTH液壓泵在(zai)排出管路閥(fa)門(men)(men)關閉狀態下(xia)(xia)啟動，旋渦泵和軸流(liu)泵在(zai)閥(fa)門(men)(men)全開狀態下(xia)(xia)啟動，以減少啟動功(gong)率(lv)。

　　輸送(song)高(gao)溫(wen)(wen)液(ye)體(ti)(ti)的(de)多級REXROTH液(ye)壓泵(beng)，如電廠(chang)的(de)鍋爐給(gei)水泵(beng)，在啟(qi)動前必須先暖泵(beng)。這是因為給(gei)水泵(beng)在啟(qi)動時，高(gao)溫(wen)(wen)給(gei)水流過泵(beng)內，使泵(beng)體(ti)(ti)溫(wen)(wen)度從常溫(wen)(wen)很快升高(gao)到100～200℃，這會引起泵(beng)內外和(he)各(ge)部(bu)件之間的(de)溫(wen)(wen)差，若沒有足(zu)夠長(chang)的(de)傳熱時間和(he)適當控(kong)制(zhi)溫(wen)(wen)升的(de)措施，會使泵(beng)各(ge)處膨脹不均，造(zao)成泵(beng)體(ti)(ti)各(ge)部(bu)分變形、磨損、振動和(he)軸(zhou)承抱軸(zhou)事故。
