柱塞泵機械原理

    柱塞泵機械原理

    概述

    柱塞泵柱塞往複運動總行程L是不變的，由凸輪的升程決議。柱塞每循環的供油量大小取決於供油行程,gongyouxingchengbushoutulunzhoukongzhishikebiande。gongyoukaiduanshichenbusuigongyouxingchengdebianhuaerbianhua。zhuandongzhusaikegaidonggongyouzhongleshichen，congergaidonggongyouliang。zhusaibenggongzuoshi，zaipenyoubengtulunzhoushangdetulunyuzhusaidanhuangdezuoyongxia，poshizhusaizuoshang
、下往複運動，從而完成泵油任務，泵油過程可分為以下兩個階段。

    進油過程

    當凸輪的凸起局部轉過去後
，在彈簧力的作用下，柱塞向下運動
