樂至機械密封的這三個功能一定要了解
機械密封包(bao)括壓力控(kong)制、溫度控(kong)制、流(liu)體替換(堵(du)塞)和雜質去除(chu)系(xi)(xi)統。在機械密封系(xi)(xi)統中，上述(shu)系(xi)(xi)統并不(bu)同(tong)時包(bao)括在內。密封系(xi)(xi)統的選擇主要取決于主密封件的應用范圍。例如，如...

機(ji)械密封(feng)利用機(ji)械方式傳(chuan)遞動(dong)(dong)(dong)(dong)力和運(yun)動(dong)(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong)(dong)，機(ji)械傳(chuan)動(dong)(dong)(dong)(dong)在機(ji)械工程中應用非常廣泛，有多種形式，主要包括(kuo)皮(pi)帶傳(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)齒條(tiao)傳(chuan)動(dong)(dong)(dong)(dong)和螺(luo)旋傳(chuan)動(dong)(dong)(dong)(dong)...
機(ji)械密封(feng)是靠(kao)彈性元(yuan)件(jian)(繃簧、波紋(wen)管(guan)等) 和密封(feng)液(ye)體壓(ya)(ya)力在相對運動(dong)的動(dong)環(huan)和靜(jing)環(huan)的接觸面(mian)(端(duan)面(mian))上發作一恰當的壓(ya)(ya)緊力(比壓(ya)(ya))使兩(liang)個(ge)亮光、 平(ping)直(zhi)的端(duan)面(mian)緊密貼合(he)；端(duan)面(mian)間...
機械密(mi)封(feng)是一種依靠彈性(xing)元件(jian)對(dui)動、靜環端面(mian)密(mi)封(feng)副的預緊(jin)和介質壓力與(yu)彈性(xing)元件(jian)壓力的壓緊(jin)而達到密(mi)封(feng)的軸向端面(mian)密(mi)封(feng)裝置。動環和靜環的端面(mian)組成(cheng)一對(dui)摩擦副，動環靠密(mi)封(feng)室(shi)中液(ye)...
熱水泵集(ji)式(shi)機械密(mi)封是指安(an)裝(zhuang)運行在(zai)泵類設備中起動態密(mi)封作用(yong)的裝(zhuang)置(zhi)，避免水泵蝸(gua)殼中的流體(ti)介質通過泵軸(zhou)流出。由于水泵多為輸送流體(ti)介質，具有水平安(an)裝(zhuang)、高轉速、高壓力(li)、帶(dai)...
反壓狀(zhuang)(zhuang)態是不(bu)良(liang)的工作狀(zhuang)(zhuang)態，介質中(zhong)的顆粒、雜質很(hen)容易(yi)進入密(mi)封面(mian)(mian)，使(shi)密(mi)封失效。磨軸(zhou)的主要件(jian)為橡(xiang)膠波紋(wen)管，且由于上端密(mi)封面(mian)(mian)處于不(bu)良(liang)潤(run)滑(hua)狀(zhuang)(zhuang)態，動靜環之間的摩擦力(li)矩大于橡(xiang)...
