欽州機械密封的這三個功能一定要了解
機械密封包括(kuo)壓力控制(zhi)、溫度控制(zhi)、流體替換(堵(du)塞(sai))和雜質去除系(xi)(xi)統(tong)。在(zai)機械密封系(xi)(xi)統(tong)中,上(shang)述系(xi)(xi)統(tong)并(bing)不同時包括(kuo)在(zai)內。密封系(xi)(xi)統(tong)的選擇主要(yao)取(qu)決于主密封件的應用范圍。例如,如...

機(ji)械(xie)密封利用機(ji)械(xie)方式傳(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong)(dong),機(ji)械(xie)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)在機(ji)械(xie)工程(cheng)中應用非常廣泛,有多種形式,主要包括皮(pi)帶(dai)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條(tiao)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)螺(luo)旋傳(chuan)(chuan)動(dong)(dong)(dong)(dong)...
機械密(mi)封是靠彈性元件(繃簧(huang)、波紋管等(deng)) 和(he)密(mi)封液體壓(ya)力(li)在相對運動的動環和(he)靜環的接觸面(mian)(端面(mian))上(shang)發作一恰當的壓(ya)緊(jin)力(li)(比(bi)壓(ya))使(shi)兩個亮光、 平直的端面(mian)緊(jin)密(mi)貼(tie)合;端面(mian)間...
機械密(mi)(mi)封(feng)是(shi)一種依靠彈性元(yuan)件對(dui)動、靜環(huan)端面(mian)(mian)密(mi)(mi)封(feng)副的(de)(de)預緊和介質壓力與(yu)彈性元(yuan)件壓力的(de)(de)壓緊而達到(dao)密(mi)(mi)封(feng)的(de)(de)軸向端面(mian)(mian)密(mi)(mi)封(feng)裝置。動環(huan)和靜環(huan)的(de)(de)端面(mian)(mian)組成一對(dui)摩擦副,動環(huan)靠密(mi)(mi)封(feng)室(shi)中液...
熱水泵(beng)集式機械密封是指安裝運行在泵(beng)類設備中起動態密封作用的裝置,避免(mian)水泵(beng)蝸殼中的流體(ti)介質通過(guo)泵(beng)軸流出。由于水泵(beng)多(duo)為輸送流體(ti)介質,具有水平安裝、高轉速(su)、高壓力、帶(dai)...
反壓狀態(tai)是不良的(de)(de)工作狀態(tai),介質中(zhong)的(de)(de)顆粒、雜質很容(rong)易進入(ru)密封面,使密封失效。磨軸的(de)(de)主要(yao)件為橡(xiang)膠波紋管,且(qie)由于上(shang)端密封面處于不良潤滑狀態(tai),動靜環之間(jian)的(de)(de)摩擦力矩大于橡(xiang)...
