汶川液壓密封件形式與材料的選擇
在液壓(ya)(ya)系統中，常(chang)見的密(mi)(mi)(mi)(mi)封(feng)(feng)形(xing)(xing)(xing)式有擠壓(ya)(ya)型O形(xing)(xing)(xing)密(mi)(mi)(mi)(mi)封(feng)(feng)圈(quan)、Y形(xing)(xing)(xing)圈(quan)、V形(xing)(xing)(xing)圈(quan)、U形(xing)(xing)(xing)圈(quan)唇形(xing)(xing)(xing)密(mi)(mi)(mi)(mi)封(feng)(feng)。唇形(xing)(xing)(xing)密(mi)(mi)(mi)(mi)封(feng)(feng)圈(quan)主要用于往復(fu)動(dong)密(mi)(mi)(mi)(mi)封(feng)(feng)，與O形(xing)(xing)(xing)圈(quan)等(deng)擠壓(ya)(ya)密(mi)(mi)(mi)(mi)封(feng)(feng)相比，往復(fu)動(dong)密(mi)(mi)(mi)(mi)封(feng)(feng)使(shi)用唇形(xing)(xing)(xing)密(mi)(mi)(mi)(mi)封(feng)(feng)圈(quan)具...
