缸體加溫?zé)嵫b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。
(2)熔燒結(jié)合方式的缸體與銅套,修復(fù)方法如下:
(a)采用研磨棒,手工或機械方法研磨修復(fù)缸孔;
(b)采用座標鏜床,重新鏜缸體孔;
(c)采用鉸刀修復(fù)缸體孔。

REXROTH柱塞泵上供油,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(guān)閉,停止供油。此后柱塞還要上行,當凸輪的凸起部分轉(zhuǎn)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(huán)。 結(jié)論:通過上述討論,得出下列結(jié)論
① 柱塞往復(fù)運動總行程L是不變的,由凸輪的升程決定。
② 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。
③ 供油開始時刻不隨供油行程的變化而變化。
④ 轉(zhuǎn)動柱塞可改變供油終了時刻,從而改變供油量。
