建水液壓密封件形式與材料的選擇
在(zai)液壓(ya)系統中,常見(jian)的密封(feng)(feng)(feng)形(xing)式有擠壓(ya)型O形(xing)密封(feng)(feng)(feng)圈(quan)、Y形(xing)圈(quan)、V形(xing)圈(quan)、U形(xing)圈(quan)唇形(xing)密封(feng)(feng)(feng)。唇形(xing)密封(feng)(feng)(feng)圈(quan)主要用(yong)于往復(fu)動密封(feng)(feng)(feng),與O形(xing)圈(quan)等擠壓(ya)密封(feng)(feng)(feng)相比(bi),往復(fu)動密封(feng)(feng)(feng)使用(yong)唇形(xing)密封(feng)(feng)(feng)圈(quan)具(ju)...
