柱塞在壓排結束時,柱塞底腔內仍舊會殘存一些為出口壓力 的油液,在柱塞進入吸入行程時,首先開始膨脹,壓力降至吸入壓力 ,這樣便損失一部分吸入容積。因此采用了充填尼龍的柱塞,可以有效的減少柱塞底腔的殘留空間,從而減少油液壓彈性容積損失,提高容積效率。
傳統設計中缸套所使用的材料基本都是軸承鋼,從經濟的角度考慮來說是比普通鋼材要貴的,并且這種材料硬度高十分不好加工,所以我這次選用的是40Cr,即經濟又便于加工。一般泵的壽命與配油盤和柱塞與缸體之間的滑動部分的擦傷等是有關,所以給缸體增加缸套,如果有擦傷的情況發生,只需更換一個缸套就可以了,從而不用去更換一個新的缸體,這樣既經濟又方便,也延長了泵的使用壽命。
