力士樂柱塞泵A10VSO28DFR/31R-PSA12N00天津總經(jīng)銷

力士樂柱塞泵是液壓系統(tǒng)的一個重要裝置，它依靠柱塞在缸體中往復(fù)運動，使密封工作容腔的容積發(fā)生變化來實現(xiàn)吸油、壓油。柱塞泵具有額定壓力高、結(jié)構(gòu)緊湊、效率高和流量調(diào)節(jié)方便等優(yōu)點。直軸斜盤式柱塞泵分為壓力供油型和自吸油型兩種。柱塞往復(fù)運動總行程L是不變的，由凸輪的升程決定。缸體上均布有若干個（7或9個）軸向排列的柱塞，柱塞與缸體孔以很精密的間隙配合，一端頂在斜盤上，當(dāng)齒輪泵泵軸與缸體固連在一起旋轉(zhuǎn)時，柱塞既能隨缸體在泵軸的帶動下一起轉(zhuǎn)動，又能在缸體的孔內(nèi)靈活往復(fù)移動，柱塞在缸體內(nèi)自下而上旋轉(zhuǎn)的左上半周內(nèi)逐漸向左伸出，使缸體孔右端的T作腔體積不斷增加，產(chǎn)生局部真空，油液經(jīng)配油盤上吸油腔被吸進來。反之，當(dāng)柱塞在其自上而下回轉(zhuǎn)的右下半周內(nèi)逐漸向右縮回缸內(nèi)，使密封工作腔體積不斷減小，將油從配油盤上的排油膠向外壞出。缸體每轉(zhuǎn)一轉(zhuǎn)，每個柱塞往復(fù)運動一次，完成一次壓油和一次吸油。缸體連續(xù)旋轉(zhuǎn)，則每個柱塞不斷吸油和壓油，給液壓系統(tǒng)提供連續(xù)的壓力油。
