朔城液壓密封件形式與材料的選擇
在液(ye)壓系統中,常見的密(mi)(mi)封(feng)(feng)形(xing)(xing)式有擠壓型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(yao)用于往復動(dong)密(mi)(mi)封(feng)(feng),與(yu)O形(xing)(xing)圈(quan)(quan)等擠壓密(mi)(mi)封(feng)(feng)相比,往復動(dong)密(mi)(mi)封(feng)(feng)使用唇形(xing)(xing)密(mi)(mi)封(feng)(feng)圈(quan)(quan)具(ju)...
