柱塞泵A10VSO28DFR1/31R-PPA12N00 現(xiàn)貨

REXROTH柱塞泵往復(fù)運(yùn)動(dòng)的總行程L是常數(shù)，由凸輪的升程決定。柱塞每個(gè)循環(huán)的供油量不受凸輪軸控制，取決于可變供油行程。供油行程的變化不會(huì)改變供油開(kāi)始時(shí)間。當(dāng)柱塞轉(zhuǎn)動(dòng)時(shí)，加油結(jié)束時(shí)間發(fā)生變化，加油量發(fā)生變化。當(dāng)REXROTH柱塞泵啟動(dòng)時(shí)，噴油泵的凸輪軸凸輪和柱塞彈簧作用，使柱塞上下往復(fù)運(yùn)動(dòng)，完成抽油任務(wù)。

REXROTH柱塞泵有兩個(gè)方向相反的止回閥。當(dāng)柱塞向一個(gè)方向移動(dòng)時(shí)，在氣缸中產(chǎn)生負(fù)壓并完成一項(xiàng)壓縮后閥門(mén)打開(kāi)。當(dāng)液體被吸入氣缸，柱塞向相反方向移動(dòng)時(shí)，液體被壓縮后另一個(gè)單向閥打開(kāi)，吸入氣缸的液體被排出。在這種工作方式下連續(xù)運(yùn)動(dòng)后，形成連續(xù)供油。

柱塞泵有兩個(gè)單向的閥門(mén)，且呈相反的方向；是屬于液壓系統(tǒng)的重要裝置，工作的原理是依靠柱塞在缸體進(jìn)行的往復(fù)運(yùn)動(dòng)，使泵在密封工作時(shí)容腔里的容積產(chǎn)生變化，來(lái)完成吸油、壓油的過(guò)程，依靠泵軸的偏心轉(zhuǎn)動(dòng)驅(qū)動(dòng)，進(jìn)而實(shí)現(xiàn)往復(fù)運(yùn)動(dòng)過(guò)程；當(dāng)柱塞向外運(yùn)動(dòng)時(shí)，缸內(nèi)會(huì)呈現(xiàn)負(fù)壓狀態(tài)，與之同時(shí)其中的一個(gè)單向閥門(mén)打開(kāi)，液體被吸入缸內(nèi)；當(dāng)柱塞向內(nèi)運(yùn)動(dòng)，合上時(shí)缸內(nèi)壓力增強(qiáng)，此時(shí)另一個(gè)單向閥門(mén)打開(kāi)，吸入缸內(nèi)的液體排出；泵軸的偏心轉(zhuǎn)動(dòng)不停的驅(qū)動(dòng)柱塞內(nèi)外往復(fù)，達(dá)到完成吸油和排油的目的，這個(gè)過(guò)程有點(diǎn)像兒時(shí)玩過(guò)的注射器，只是注射器進(jìn)出都是一個(gè)閥口，柱塞泵將其分開(kāi)，原理很相似，非常好理解。

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減少。
