機(ji)械(xie)密(mi)封利用機(ji)械(xie)方式傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機(ji)械(xie)工(gong)程中應用非常廣泛，有多種形式，主要包括皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)(lun)齒(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)...
機械密封(feng)是靠彈性元件(繃簧、波紋管等(deng)) 和密封(feng)液體壓力(li)在相(xiang)對(dui)運動(dong)(dong)的(de)動(dong)(dong)環(huan)和靜環(huan)的(de)接觸面(mian)(端(duan)面(mian))上發作一恰當(dang)的(de)壓緊(jin)力(li)(比壓)使(shi)兩個亮光、 平直的(de)端(duan)面(mian)緊(jin)密貼(tie)合；端(duan)面(mian)間...
機械密封是一(yi)(yi)種(zhong)依靠彈性(xing)元件對動(dong)、靜環端(duan)面密封副的(de)預緊(jin)和(he)介質壓(ya)(ya)力與(yu)彈性(xing)元件壓(ya)(ya)力的(de)壓(ya)(ya)緊(jin)而達到密封的(de)軸向端(duan)面密封裝置。動(dong)環和(he)靜環的(de)端(duan)面組成一(yi)(yi)對摩擦副，動(dong)環靠密封室中液...
熱水(shui)泵(beng)集式機械密(mi)(mi)封(feng)是指安裝運行在泵(beng)類設備中(zhong)起動態(tai)密(mi)(mi)封(feng)作用的(de)裝置(zhi)，避免水(shui)泵(beng)蝸殼中(zhong)的(de)流(liu)體介質通(tong)過(guo)泵(beng)軸流(liu)出。由于水(shui)泵(beng)多為(wei)輸(shu)送流(liu)體介質，具(ju)有水(shui)平(ping)安裝、高轉速、高壓力、帶...
反壓狀態是不(bu)良的工(gong)作狀態，介(jie)質中的顆粒、雜質很(hen)容易進入密(mi)封(feng)面，使密(mi)封(feng)失效。磨軸的主要件為橡膠波紋管(guan)，且由于上(shang)端密(mi)封(feng)面處于不(bu)良潤(run)滑狀態，動靜環之間的摩擦力矩大于橡...
