b.后退電磁(ci)鐵通電，油(you)泵輸出(chu)的(de)工作油(you)經(jing)單向(xiang)閥在溢(yi)流閥調定壓(ya)力下經(jing)插(cha)裝(zhuang)閥進(jin)人推料油(you)缸的(de)前腔(qiang)，推料油(you)缸后腔(qiang)的(de)油(you)經(jing)插(cha)裝(zhuang)閥回人油(you)箱，推料油(you)缸后退回程。

⑤壓(ya)料油缸壓(ya)料和回程

①壓(ya)(ya)料電(dian)磁鐵通電(dian)，油(you)泵輸出的(de)(de)工(gong)作油(you)經單(dan)向閥(fa)在溢流閥(fa)調定壓(ya)(ya)力下經插裝閥(fa)進人(ren)壓(ya)(ya)料油(you)缸的(de)(de)后腔(qiang)，壓(ya)(ya)料油(you)缸前腔(qiang)的(de)(de)油(you)經插裝閥(fa)回人(ren)油(you)箱(xiang)，壓(ya)(ya)料油(you)缸前進壓(ya)(ya)料。

②回程(cheng)電磁鐵通(tong)電，油(you)泵輸出(chu)的工作油(you)經單向閥在(zai)溢流閥調定壓力(li)下(xia)經插裝閥進人壓料油(you)缸(gang)的前腔，壓料油(you)缸(gang)后腔的油(you)經插裝閥回入油(you)箱，壓料油(you)缸(gang)后退回程(cheng)。
