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,當原動機通過傳動軸使缸體轉動時,由于斜盤的作用,迫使柱塞在缸體內作往復運動,并通過配油盤的配油窗口進行吸油和壓油。如圖3-23中所示回轉方向,當缸體轉角在π~2π范圍內,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,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缺點簡介力士樂Rexroth柱塞泵的優點
