REXROTH軸向柱塞泵,泵體結(jié)構分析
德國REXROTH力士樂直軸斜盤式柱塞泵:
直軸斜盤式柱塞泵分為壓力供油型和自吸油型兩種。壓力供油型液壓泵大都是采用有氣壓的油箱,靠氣壓供油的液壓油箱,在每次啟動機器之后,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啟動機器,會對液壓泵內(nèi)的與滑靴造成拉脫現(xiàn)象,出會造成泵體內(nèi)回程板與壓板的非正常磨損。
REXROTH力士樂徑向式柱塞泵:
徑向柱塞泵可分為閥配流與軸配流兩大類。閥配流徑向柱塞泵存在故障率高、效率低等缺點。上70、80年代發(fā)展的軸配流徑向柱塞泵克服了閥配流徑向柱塞泵的不足。由于徑向泵結(jié)構上的特點,固定了軸配流徑向柱塞泵比軸向柱塞泵耐沖擊、壽命長、控制精度高。變量行程短泵的變量是在變量柱塞和限位柱塞作用下,改變定子的偏心距實現(xiàn)的,而定于的zui大偏心距為 5—9mm(根據(jù)排量大小不同),變量行程很短。且變量機構設計為高壓操縱,由控制閥進行控制。故該泵的響應速度快。徑向結(jié)構設計克服了如軸向柱塞泵滑靴偏磨的問題。使其抗沖擊能力大幅度提高。
