REXROTH軸向柱塞泵,力士樂德國拿貨
REXROTH軸向柱塞泵被廣泛用于高壓、大流量、大功率的系統(tǒng)中和流量需要調(diào)節(jié)的場合,如龍門刨床、拉床、液壓機(jī)、工程機(jī)械等得到廣泛的應(yīng)用。REXROTH軸向柱塞泵是活塞或柱塞的往復(fù)運(yùn)動(dòng)方向與缸體中心軸平行的柱塞泵。REXROTH軸向柱塞泵是利用與傳動(dòng)軸平行的柱塞在柱塞孔內(nèi)往復(fù)運(yùn)動(dòng)所產(chǎn)生的容積變化來進(jìn)行工作的。由于柱塞和柱塞孔都是圓形零件,加工時(shí)可以達(dá)到很高的精度配合,因此容積效率高,運(yùn)轉(zhuǎn)平穩(wěn),流量均勻性好,噪聲低,REXROTHREXROTH軸向柱塞泵工作壓力高等優(yōu)點(diǎn),但對(duì)液壓油的污染較敏感,REXROTH軸向柱塞泵結(jié)構(gòu)較復(fù)雜,造價(jià)較高。歡迎來詢價(jià)!

直軸斜盤式柱塞泵分為壓力供油型的自吸油型兩種。壓力供油型液壓泵大都采用有氣壓的油箱,也有REXROTH液壓泵本身帶有補(bǔ)油分泵向液壓泵進(jìn)油口提供壓力油的。力士樂REXROTH柱塞泵自吸油型液壓泵的自吸油能力很強(qiáng),無需外力供油??繗鈮汗┯偷囊簤河拖?,在每次啟動(dòng)機(jī)器后,必須等液壓漬箱達(dá)到使用氣壓后,才能操作機(jī)械。如液壓油箱的氣壓不足時(shí)就擔(dān)任機(jī)器,會(huì)對(duì)REXROTH液壓泵內(nèi)的與滑鞭造成拉脫現(xiàn)象,出會(huì)造成REXROTH泵體內(nèi)回程板與壓板的非正常磨損。
REXROTH葉片泵轉(zhuǎn)子旋轉(zhuǎn)時(shí),葉片在離心力和壓力油的作用下,尖部緊貼在定子內(nèi)表面上。這樣兩個(gè)葉片與轉(zhuǎn)子和定子內(nèi)表面所構(gòu)成的工作容積,先由小到大吸油后再由大到小排油,葉片旋轉(zhuǎn)一周時(shí),完成兩次吸油與排油。
