西烏珠穆沁機械密封的這三個功能一定要了解
機(ji)械密封包括壓力控制、溫(wen)度控制、流體替換(堵塞(sai))和(he)雜質(zhi)去除系(xi)統。在(zai)機(ji)械密封系(xi)統中(zhong),上(shang)述系(xi)統并不同(tong)時包括在(zai)內。密封系(xi)統的選擇主要取(qu)決于主密封件的應用范(fan)圍。例如,如...

雙端面小彈(dan)簧平衡(heng)型密(mi)封(feng)所用摩(mo)擦副材料由動環(huan)和靜(jing)環(huan)所組成的摩(mo)擦副是(shi)機械密(mi)封(feng)重要的零件(jian),從理論上講,為了減少機械密(mi)封(feng)的磨損量,應該在合理的動力流體(ti)潤滑(hua)條件(jian)下工作運轉...
我們使用泵(beng)過(guo)程中總會遇到(dao)密封膠圈損壞的(de)情況,一旦(dan)損壞就(jiu)要進行更換(huan),作為一個工(gong)程技術(shu)人員首先要分(fen)辨(bian)自(zi)己的(de)泵(beng)到(dao)底是哪種型號,才(cai)能購買到(dao)相應口徑的(de)機械密封,由于在市場...
在(zai)使(shi)用過(guo)程(cheng)中,大多數(shu)機(ji)械密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)都屬于接(jie)觸式密(mi)(mi)(mi)(mi)封(feng)(feng)(feng),其機(ji)理是靠動密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)環與靜密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)環的(de)(de)接(jie)觸端面在(zai)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)流體(ti)壓力和彈性元件壓緊力的(de)(de)作(zuo)用下緊密(mi)(mi)(mi)(mi)貼合(he),并相對(dui)滑(hua)動而達到密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)。工(gong)作(zuo)時...
機(ji)械(xie)密封利用(yong)機(ji)械(xie)方式傳(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong),機(ji)械(xie)傳(chuan)動(dong)(dong)(dong)在機(ji)械(xie)工程中應用(yong)非常廣泛,有(you)多種形式,主要包(bao)括皮帶傳(chuan)動(dong)(dong)(dong)、齒(chi)輪傳(chuan)動(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)動(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)動(dong)(dong)(dong)和螺旋傳(chuan)動(dong)(dong)(dong)...
由于(yu)有氣囊的存在,氮(dan)氣與隔離液(ye)完(wan)全不接觸,避免了加壓(ya)氣體被隔離液(ye)吸收(shou),使(shi)填(tian)料改(gai)集式密封可以用于(yu)液(ye)力透平(ping)等(deng)高(gao)壓(ya)操作工(gong)況,但是(shi)由于(yu)隔離液(ye)是(shi)在換(huan)熱器的盤(pan)管中流動(dong),因此(ci)...
