河西液壓密封件形式與材料的選擇
在液壓(ya)系統中，常(chang)見的密(mi)(mi)封(feng)(feng)形(xing)(xing)式有擠(ji)壓(ya)型O形(xing)(xing)密(mi)(mi)封(feng)(feng)圈(quan)(quan)、Y形(xing)(xing)圈(quan)(quan)、V形(xing)(xing)圈(quan)(quan)、U形(xing)(xing)圈(quan)(quan)唇形(xing)(xing)密(mi)(mi)封(feng)(feng)。唇形(xing)(xing)密(mi)(mi)封(feng)(feng)圈(quan)(quan)主要用(yong)于往(wang)復動密(mi)(mi)封(feng)(feng)，與O形(xing)(xing)圈(quan)(quan)等擠(ji)壓(ya)密(mi)(mi)封(feng)(feng)相比，往(wang)復動密(mi)(mi)封(feng)(feng)使用(yong)唇形(xing)(xing)密(mi)(mi)封(feng)(feng)圈(quan)(quan)具...
