碾子山機械密封的這三個功能一定要了解
機械密(mi)封(feng)包(bao)括(kuo)壓力控制、溫度控制、流體替換(huan)(堵(du)塞)和雜質去除系(xi)統(tong)。在機械密(mi)封(feng)系(xi)統(tong)中，上述系(xi)統(tong)并不同(tong)時包(bao)括(kuo)在內。密(mi)封(feng)系(xi)統(tong)的選擇主要取決于主密(mi)封(feng)件的應用(yong)范圍。例如，如...

雙端面小彈簧(huang)平衡型(xing)密(mi)封(feng)(feng)所(suo)用摩(mo)(mo)擦副材料由動(dong)環和(he)靜(jing)環所(suo)組成的(de)摩(mo)(mo)擦副是(shi)機(ji)械密(mi)封(feng)(feng)重要的(de)零(ling)件，從理(li)論上講，為了減(jian)少(shao)機(ji)械密(mi)封(feng)(feng)的(de)磨損量，應該在合理(li)的(de)動(dong)力流體潤滑條件下(xia)工作運(yun)轉...
我們(men)使(shi)用泵(beng)過(guo)程(cheng)中總會遇到(dao)密封膠(jiao)圈損壞的情況，一旦損壞就要進行更(geng)換，作為一個工程(cheng)技術(shu)人員首先要分辨(bian)自己(ji)的泵(beng)到(dao)底是(shi)哪種(zhong)型號，才能購買到(dao)相應口徑的機械密封，由于(yu)在市(shi)場...
在(zai)使用過程(cheng)中，大多(duo)數機械密(mi)封(feng)都屬于接觸式密(mi)封(feng)，其(qi)機理是靠動(dong)密(mi)封(feng)環(huan)與靜密(mi)封(feng)環(huan)的(de)接觸端面在(zai)密(mi)封(feng)流體壓力(li)(li)和彈性(xing)元(yuan)件壓緊力(li)(li)的(de)作用下緊密(mi)貼合，并相對(dui)滑動(dong)而達到密(mi)封(feng)。工作時...
機(ji)(ji)械(xie)密封利用(yong)(yong)機(ji)(ji)械(xie)方式傳(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機(ji)(ji)械(xie)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在(zai)機(ji)(ji)械(xie)工程中應用(yong)(yong)非常廣泛，有多(duo)種形式，主要(yao)包括皮帶傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)齒(chi)(chi)條傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)螺(luo)旋傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)...
由于(yu)有(you)氣囊的存(cun)在(zai)，氮氣與隔離液完全不(bu)接觸，避免了(le)加(jia)壓氣體被隔離液吸收(shou)，使填料改集式密封可以用于(yu)液力透平等(deng)高壓操作工(gong)況，但是(shi)由于(yu)隔離液是(shi)在(zai)換熱(re)器(qi)的盤管中流動(dong)，因此...
