rexroth油泵是液壓系統(tǒng)的動(dòng)力機(jī)構(gòu),它將原動(dòng)機(jī)(電動(dòng)機(jī)、內(nèi)燃機(jī)等)的機(jī)械能轉(zhuǎn)變?yōu)橐后w的壓力能。
力士樂(lè)油泵可以分為容積式和非容積室(蝸輪式)兩種。非容積式有離心泵、軸流泵等,利用高速旋轉(zhuǎn)的葉輪使進(jìn)口產(chǎn)生真空吸入液體,并在出口連續(xù)輸出壓力液體。這種泵進(jìn)口與出口相通,效率隨液體粘度增加而降低,并且輸出液體量隨出口壓力升高而顯著減少。
容積式泵是通過(guò)一個(gè)封閉的空間容積的變化來(lái)實(shí)現(xiàn)吸油和壓油的。當(dāng)這個(gè)封閉容積由小變大時(shí)進(jìn)行吸油,由大變小時(shí)進(jìn)行壓油。典型的為力士樂(lè)柱塞泵,柱塞從缸孔中拉出時(shí)吸油,壓進(jìn)時(shí)壓油。這種泵進(jìn)口與出口是被隔開(kāi)的,效率取決于隔開(kāi)吸壓油腔的各對(duì)運(yùn)動(dòng)零件間的結(jié)構(gòu)工藝間隙及油液的粘度等。粘度越高效率越高,輸油量幾乎保持不變(因效率略有影響,另外壓力升高至18MPa,油液會(huì)被壓縮1%)。
