喀什機械密封的這三個功能一定要了解
機械密(mi)封(feng)包括壓力控(kong)(kong)制、溫(wen)度控(kong)(kong)制、流體替換(堵塞)和雜(za)質去除系(xi)統。在(zai)(zai)機械密(mi)封(feng)系(xi)統中(zhong),上述系(xi)統并不同(tong)時包括在(zai)(zai)內。密(mi)封(feng)系(xi)統的選擇主要取決于主密(mi)封(feng)件的應用范圍。例(li)如(ru),如(ru)...

機(ji)械(xie)密封利(li)用機(ji)械(xie)方式傳(chuan)(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong),機(ji)械(xie)傳(chuan)(chuan)動(dong)(dong)(dong)在機(ji)械(xie)工程中應用非常廣泛,有多種形式,主要包括皮(pi)帶傳(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)動(dong)(dong)(dong)和螺旋傳(chuan)(chuan)動(dong)(dong)(dong)...
機械密(mi)封是靠彈性元(yuan)件(繃簧、波紋管等) 和密(mi)封液體壓力(li)在相對運(yun)動的(de)動環和靜環的(de)接觸(chu)面(mian)(端(duan)(duan)面(mian))上發作一(yi)恰當(dang)的(de)壓緊(jin)力(li)(比壓)使(shi)兩個(ge)亮(liang)光、 平直(zhi)的(de)端(duan)(duan)面(mian)緊(jin)密(mi)貼合;端(duan)(duan)面(mian)間(jian)...
機械(xie)密封(feng)是一種依靠彈(dan)性元(yuan)件對動、靜(jing)環(huan)(huan)端(duan)面密封(feng)副的(de)預緊(jin)和介(jie)質壓力與彈(dan)性元(yuan)件壓力的(de)壓緊(jin)而達到密封(feng)的(de)軸向(xiang)端(duan)面密封(feng)裝置。動環(huan)(huan)和靜(jing)環(huan)(huan)的(de)端(duan)面組成一對摩擦副,動環(huan)(huan)靠密封(feng)室(shi)中液(ye)...
熱水泵(beng)集式機(ji)械密封是(shi)指安裝(zhuang)運行在泵(beng)類(lei)設(she)備中起動態密封作用的裝(zhuang)置,避(bi)免水泵(beng)蝸殼(ke)中的流體(ti)介質(zhi)通過泵(beng)軸流出。由(you)于(yu)水泵(beng)多(duo)為輸送流體(ti)介質(zhi),具有水平安裝(zhuang)、高(gao)轉速、高(gao)壓力(li)、帶...
反壓狀(zhuang)態(tai)是不良的(de)(de)工作狀(zhuang)態(tai),介質中(zhong)的(de)(de)顆(ke)粒、雜質很容易進入密封(feng)面(mian),使密封(feng)失效。磨(mo)軸(zhou)的(de)(de)主要件為(wei)橡(xiang)膠波紋管,且(qie)由(you)于(yu)上端(duan)密封(feng)面(mian)處(chu)于(yu)不良潤滑狀(zhuang)態(tai),動靜環之間的(de)(de)摩擦力矩(ju)大于(yu)橡(xiang)...
