美國VICKERS@威格士柱塞泵柱塞往復(fù)運(yùn)動(dòng)總行程L是不變的，由凸輪的升程決定。VICKERS柱塞每循環(huán)的供油量大小取決于供油行程,供油行程不受凸輪軸控制是可變的。供油開始時(shí)刻不隨供油行程的變化而變化。轉(zhuǎn)動(dòng)柱塞可改變供油終了時(shí)刻，從而改變供油量。柱塞泵工作時(shí)，在噴油泵凸輪軸上的凸輪與柱塞彈簧的作用下，迫使柱塞作上、下往復(fù)運(yùn)動(dòng)，從而完成泵油任務(wù)。
威格士柱塞泵過熱 液壓泵過度發(fā)熱有兩個(gè)原因，一是機(jī)械摩擦生熱。由于運(yùn)動(dòng)表面處于干摩擦或半干摩擦狀態(tài)，運(yùn)動(dòng)部件相互摩擦生熱。二是液體摩擦生熱。高壓油通過各種縫隙泄漏到低壓腔，大量的液壓能損失轉(zhuǎn)為熱能。所以正確選擇運(yùn)動(dòng)部件之間的間隙、油箱容積和冷卻器，可以杜絕泵的過度發(fā)熱和油溫過高的現(xiàn)象。另外，回油過濾器堵塞造成回油背壓過高，也會(huì)引起油溫過高和泵體過熱。
