柱塞泵A10VSO28DFR1/31R-PPA12N00 現貨

REXROTH柱塞泵往復運動的總行程L是常數，由凸輪的升程決定。柱塞每個循環(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改變供油開始時間。當柱塞轉動時，加油結束時間發(fā)生變化，加油量發(fā)生變化。當REXROTH柱塞泵啟動時，噴油泵的凸輪軸凸輪和柱塞彈簧作用，使柱塞上下往復運動，完成抽油任務。

REXROTH柱塞泵有兩個方向相反的止回閥。當柱塞向一個方向移動時，在氣缸中產生負壓并完成一項壓縮后閥門打開。當液體被吸入氣缸，柱塞向相反方向移動時，液體被壓縮后另一個單向閥打開，吸入氣缸的液體被排出。在這種工作方式下連續(xù)運動后，形成連續(xù)供油。

柱塞泵有兩個單向的閥門，且呈相反的方向；是屬于液壓系統的重要裝置，工作的原理是依靠柱塞在缸體進行的往復運動，使泵在密封工作時容腔里的容積產生變化，來完成吸油、壓油的過程，依靠泵軸的偏心轉動驅動，進而實現往復運動過程；當柱塞向外運動時，缸內會呈現負壓狀態(tài)，與之同時其中的一個單向閥門打開，液體被吸入缸內；當柱塞向內運動，合上時缸內壓力增強，此時另一個單向閥門打開，吸入缸內的液體排出；泵軸的偏心轉動不停的驅動柱塞內外往復，達到完成吸油和排油的目的，這個過程有點像兒時玩過的注射器，只是注射器進出都是一個閥口，柱塞泵將其分開，原理很相似，非常好理解。

rexroth油泵是液壓系統的動力機構，它將原動機（電動機、內燃機等）的機械能轉變?yōu)橐后w的壓力能。力士樂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

速旋轉的葉輪使進口產生真空吸入液體，并在出口連續(xù)輸出壓力液體。這種泵進口與出口相通，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。
