寶坻機械密封的這三個功能一定要了解
機(ji)械(xie)密(mi)封包括壓力控制、溫度(du)控制、流體(ti)替換(堵(du)塞)和雜質去除系(xi)(xi)統(tong)。在機(ji)械(xie)密(mi)封系(xi)(xi)統(tong)中,上述系(xi)(xi)統(tong)并不(bu)同(tong)時包括在內。密(mi)封系(xi)(xi)統(tong)的選擇(ze)主要(yao)取決于(yu)主密(mi)封件的應用范圍。例如,如...

雙端面小(xiao)彈簧平衡(heng)型密封(feng)(feng)(feng)所用(yong)摩擦副材料由動環(huan)和靜環(huan)所組(zu)成的(de)摩擦副是機械密封(feng)(feng)(feng)重要的(de)零件,從理論(lun)上講,為(wei)了減少(shao)機械密封(feng)(feng)(feng)的(de)磨損量,應該(gai)在合(he)理的(de)動力流體潤滑(hua)條件下(xia)工作運轉(zhuan)...
我們使用(yong)泵(beng)過程中總會遇到(dao)密封膠(jiao)圈損壞的情況,一旦損壞就要進行更換,作為一個工程技術人員首先要分辨自己的泵(beng)到(dao)底是(shi)哪(na)種型號,才能購買到(dao)相(xiang)應口(kou)徑(jing)的機械(xie)密封,由于在市場...
在使(shi)用過程中,大多數(shu)機械密(mi)封(feng)都屬于接(jie)觸式密(mi)封(feng),其(qi)機理是靠(kao)動密(mi)封(feng)環與靜密(mi)封(feng)環的接(jie)觸端(duan)面在密(mi)封(feng)流體壓力和彈性元(yuan)件(jian)壓緊(jin)力的作(zuo)用下緊(jin)密(mi)貼合,并相對滑動而達到密(mi)封(feng)。工作(zuo)時...
機械密封利用(yong)機械方式(shi)傳(chuan)(chuan)遞(di)動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong),機械傳(chuan)(chuan)動(dong)(dong)(dong)在(zai)機械工(gong)程中應用(yong)非(fei)常廣泛,有多種形式(shi),主要包括(kuo)皮帶傳(chuan)(chuan)動(dong)(dong)(dong)、齒輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)、齒輪(lun)齒條傳(chuan)(chuan)動(dong)(dong)(dong)和螺旋(xuan)傳(chuan)(chuan)動(dong)(dong)(dong)...
由(you)于(yu)(yu)(yu)有(you)氣囊的存(cun)在(zai),氮氣與隔離(li)液完全不接觸,避免了加壓氣體被隔離(li)液吸收,使填料改集式密(mi)封可以用于(yu)(yu)(yu)液力透平等(deng)高(gao)壓操作(zuo)工況,但是由(you)于(yu)(yu)(yu)隔離(li)液是在(zai)換熱器的盤管中流動,因此(ci)...
