聯系人：白建新  力士樂柱塞泵A10VSO71DR/31R-PPA12N00 柱塞泵是液壓系統的一個重要裝置。它依靠柱塞在缸體中往復運動，使密封工作容腔的容積發生變化來實現吸油、壓油。柱塞泵具有額定壓力高、結構緊湊、效率高和流量調節方便等優點。柱塞泵被廣泛應用于高壓、大流量和流量需要調節的場合，諸如液壓機、工程機械和船舶中

回油過程

柱塞向上供油，當上行到柱塞上的斜槽（停供邊）與套筒上的回油孔相通時，泵油室低壓油路便與柱塞頭部的中孔和徑向孔及斜槽溝通，油壓驟然下降，出油閥在彈簧力的作用下迅速關閉，停止供油。此后柱塞還要上行，當凸輪的凸起部分轉過去后，在彈簧的作用下，柱塞又下行。此時便開始了下一個循環。柱塞泵以一個柱塞為原理介紹，一個柱塞泵上有兩個單向閥，并且方向相反，柱塞向一個方向運動時缸內出現負壓，這時一個單向閥打開液體被吸入缸內，柱塞向另一個方向運動時，將液體壓縮后另一個單向閥被打開，被吸入缸內的液體被排出。這種工作方式連續運動后就形成了連續供油 。 [1] 

機械使用

編輯柱塞泵缸體鑲裝銅套的，可以采用更換銅套的方法安裝。首先把一組柱塞桿外徑修整到統一尺寸，再用1000#以上的砂紙拋光外徑。缸體安裝銅套的三種方法：（a）缸體加溫熱裝或銅套低溫冷凍擠壓，過盈裝配；（b）采有樂泰膠粘著裝配，這咱方法要求銅外套外徑表面有溝槽；（c）缸孔攻絲，銅套外徑加工螺紋，涂樂泰膠后，旋入裝配。 [1] 熔燒結合方式的缸體與銅套，安裝方法如下：（a）采用研磨棒，手工或機械方法研磨修復缸孔；（b）采用坐標鏜床，重新鏜缸體孔；（c）采用鉸刀修復缸體孔。 [1] 采用“表面工程技術”，方法如下：（a）電鍍技術：在柱塞表面鍍一層硬鉻；（b）電刷鍍技術：在柱塞表面刷鍍耐磨材料；（c）熱噴涂或電弧噴涂或電噴涂：噴涂高碳馬氏體耐磨材料；（d）激光熔敷：在柱塞表面熔敷高硬度耐磨合金粉末。（4）缸體孔無銅套的缸體材料大都是球墨鑄鐵的，在缸體內壁上制備非晶態薄膜或涂層。因為缸體孔內壁有了這種特殊物質，所以才能組成硬—硬配對的磨擦副
