rexroth力士樂柚向柱塞泵rexroth力士樂柚向柱塞泵斜盤軸線與缸體軸線傾斜一角度,柱塞靠機械裝置或在低壓油作用下壓緊在斜盤上(圖中為彈簧),配油盤2和斜盤4固定不轉(zhuǎn),當原動機通過傳動軸使缸體轉(zhuǎn)動時,由于斜盤的作用,迫使柱塞在缸體內(nèi)作往復運動,并通過配油盤的配油窗口進行吸油和壓油。如圖3-23中所示回轉(zhuǎn)方向,當缸體轉(zhuǎn)角在π~2π范圍內(nèi),柱塞向外伸出,柱塞底部缸孔的密封工作容積增大,通過配油盤的吸油窗口吸油;在0~π范圍內(nèi),柱塞被斜盤推入缸體,使缸孔容積減小,通過配油盤的壓油窗口壓油。缸體每轉(zhuǎn)一周,每個柱塞各完成吸、壓油一次,如改變斜盤傾角,就能改變柱塞行程的長度,即改變液壓泵的排量,改變斜盤傾角方向,就能改變吸油和壓油的方向,即成為雙向變量泵。
rexroth力士樂軸向柱塞泵的優(yōu)缺點簡介力士樂Rexroth柱塞泵的優(yōu)點
1. 參數(shù)高:額定壓力高,轉(zhuǎn)速高,力士樂油泵的驅(qū)動功率大
2. 效率高,容積效率為95%左右,總效率為90%左右
3. 壽命長
4. 變量方便,形式多
5. 單位功率的重量輕
6. 力士樂柱塞泵主要零件均受壓應(yīng)力,材料強度性能可得以充分利用力士樂rexroth柱塞泵的缺點適用于開式回路液壓驅(qū)動
