REXROTH軸向柱塞泵,力士樂德國拿貨
【產(chǎn)品簡介】
【詳細說明】
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、工程機械等得到廣泛的應用。REXROTH軸向柱塞泵是活塞或柱塞的往復運動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軸平行的柱塞在柱塞孔內(nèi)往復運動所產(chǎn)生的容積變化來進行工作的。由于柱塞和柱塞孔都是圓形零件,加工時可以達到很高的精度配合,因此容積效率高,運轉(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,但對液壓油的污染較敏感,REXROTH軸向柱塞泵結(jié)構(gòu)較復雜,造價較高。歡迎來詢價!

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液壓泵本身帶有補油分泵向液壓泵進油口提供壓力油的。力士樂REXROTH柱塞泵自吸油型液壓泵的自吸油能力很強,無需外力供油??繗鈮汗┯偷囊簤河拖洌诿看螁訖C器后,必須等液壓漬箱達到使用氣壓后,才能操作機械。如液壓油箱的氣壓不足時就擔任機器,會對REXROTH液壓泵內(nèi)的與滑鞭造成拉脫現(xiàn)象,出會造成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,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,完成兩次吸油與排油。
