祁縣機械密封的這三個功能一定要了解
機械密封包括壓力(li)控(kong)制(zhi)、溫度控(kong)制(zhi)、流(liu)體替換(堵塞)和雜質去(qu)除系(xi)統(tong)(tong)。在(zai)機械密封系(xi)統(tong)(tong)中,上述系(xi)統(tong)(tong)并不同時包括在(zai)內。密封系(xi)統(tong)(tong)的(de)(de)選擇主要取決于(yu)主密封件的(de)(de)應用范圍。例如,如...

雙端面小彈(dan)簧平衡型(xing)密封所用摩擦副(fu)(fu)材料由(you)動環和(he)靜環所組成的摩擦副(fu)(fu)是機械密封重要的零件,從理論(lun)上講,為了減少機械密封的磨(mo)損量,應該在(zai)合理的動力流體潤滑條件下工作運轉...
我們使用泵(beng)過程中總會遇(yu)到(dao)密封膠圈損(sun)壞的(de)情況,一(yi)旦(dan)損(sun)壞就要(yao)進行(xing)更換(huan),作為一(yi)個工程技術人員首先(xian)要(yao)分辨自己(ji)的(de)泵(beng)到(dao)底(di)是哪種型號,才能購買(mai)到(dao)相應(ying)口徑的(de)機械密封,由于在(zai)市場...
在使用過程中,大多數機械(xie)密(mi)(mi)(mi)封(feng)(feng)(feng)都(dou)屬于接觸式密(mi)(mi)(mi)封(feng)(feng)(feng),其機理是靠動(dong)密(mi)(mi)(mi)封(feng)(feng)(feng)環與靜密(mi)(mi)(mi)封(feng)(feng)(feng)環的(de)接觸端面(mian)在密(mi)(mi)(mi)封(feng)(feng)(feng)流(liu)體壓(ya)力(li)和彈性元(yuan)件(jian)壓(ya)緊(jin)力(li)的(de)作用下緊(jin)密(mi)(mi)(mi)貼(tie)合,并(bing)相對(dui)滑(hua)動(dong)而(er)達到密(mi)(mi)(mi)封(feng)(feng)(feng)。工作時...
機(ji)械(xie)(xie)密封(feng)利用機(ji)械(xie)(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)(xie)傳(chuan)動(dong)(dong)(dong)在機(ji)械(xie)(xie)工程(cheng)中應用非常廣泛,有多種形式,主要包括(kuo)皮帶(dai)傳(chuan)動(dong)(dong)(dong)、齒輪(lun)(lun)傳(chuan)動(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)、蝸桿蝸輪(lun)(lun)傳(chuan)動(dong)(dong)(dong)、齒輪(lun)(lun)齒條傳(chuan)動(dong)(dong)(dong)和螺旋傳(chuan)動(dong)(dong)(dong)...
由(you)于(yu)有(you)氣囊(nang)的(de)存(cun)在(zai),氮氣與(yu)隔離(li)(li)液(ye)(ye)完全不(bu)接觸,避(bi)免(mian)了加壓氣體被隔離(li)(li)液(ye)(ye)吸收(shou),使填料改集式密封可(ke)以用于(yu)液(ye)(ye)力透平等高壓操作工況(kuang),但是由(you)于(yu)隔離(li)(li)液(ye)(ye)是在(zai)換熱(re)器的(de)盤管(guan)中流(liu)動(dong),因此...
