德國Rexroth力士樂葉片泵原理簡介
Rexroth力士樂雙作用泵工作原理:它由定子、轉(zhuǎn)子、葉片和配油盤等組成。定子內(nèi)壁近似橢圓形。葉片安裝在轉(zhuǎn)子徑向槽內(nèi)并可沿槽滑動,轉(zhuǎn)子與定子同心安裝。當(dāng)轉(zhuǎn)子轉(zhuǎn)動時,葉片在離心力的作用下壓向定子內(nèi)表面,并隨定子內(nèi)表面曲線的變化而被迫在轉(zhuǎn)子槽內(nèi)往復(fù)滑動,相鄰兩葉片間的密封工作腔就發(fā)生增大和縮小的變化。葉片由小半徑圓弧向大半徑圓弧處滑移時,密封工作腔隨之逐漸增大形成局部真空,于是油箱中油液通過配油盤上吸油腔吸入;反之將油壓出。轉(zhuǎn)子每轉(zhuǎn)一周,葉片在槽內(nèi)往復(fù)滑移2次,完成2次吸油和2次壓油,并且油壓所產(chǎn)生的徑向力是平衡的,故稱雙作用式,也稱平衡式。
單作用式葉片泵工作原理:主要由定子、轉(zhuǎn)子、葉片和配油盤等組成。定子的內(nèi)表面是一個圓柱形,轉(zhuǎn)子偏心安裝在定子中,即有一個偏心距e,葉片裝在轉(zhuǎn)子徑向滑槽中,并可在槽內(nèi)徑向滑動。轉(zhuǎn)子轉(zhuǎn)動時,在離心力和葉片根部壓力油的作用下,葉片緊貼在定子內(nèi)表面上,這樣相鄰兩片葉片間就形成了密封工作腔。在其中一邊,葉片逐漸伸出,密封工作腔逐漸增大,形成局部真空,形成吸油;反之,另一邊,形成壓油。轉(zhuǎn)子每轉(zhuǎn)一周,葉片在滑槽內(nèi)往復(fù)滑移1次,完成1次吸油1次壓油。油壓所產(chǎn)生的徑向力是不平衡的,故稱單作用式,也稱不平衡式葉片泵。
