延吉機械密封的這三個功能一定要了解
機械密封包(bao)括(kuo)壓力控制、溫度(du)控制、流體替換(堵塞)和(he)雜質去除(chu)系統(tong)(tong)。在機械密封系統(tong)(tong)中,上述系統(tong)(tong)并不同(tong)時包(bao)括(kuo)在內。密封系統(tong)(tong)的選擇主要取決于主密封件的應用(yong)范圍。例如,如...

雙(shuang)端面小(xiao)彈簧(huang)平衡(heng)型(xing)密(mi)(mi)封所用摩(mo)擦(ca)副材料由動環(huan)和靜(jing)環(huan)所組成(cheng)的(de)摩(mo)擦(ca)副是機械密(mi)(mi)封重要(yao)的(de)零(ling)件(jian),從理論上講,為了(le)減少機械密(mi)(mi)封的(de)磨損量,應該在合(he)理的(de)動力流體潤滑條件(jian)下工(gong)作運轉(zhuan)...
我(wo)們使用泵(beng)過(guo)程(cheng)中總會遇到(dao)密(mi)封(feng)膠圈(quan)損壞的情(qing)況,一旦損壞就(jiu)要(yao)進(jin)行更換,作為一個工(gong)程(cheng)技術人員首(shou)先要(yao)分辨自己的泵(beng)到(dao)底是哪種(zhong)型號,才(cai)能購買到(dao)相應口徑(jing)的機(ji)械(xie)密(mi)封(feng),由于在市(shi)場...
在使(shi)用過程(cheng)中(zhong),大多數機(ji)械密(mi)封(feng)(feng)都屬(shu)于接觸式密(mi)封(feng)(feng),其(qi)機(ji)理是靠動密(mi)封(feng)(feng)環與靜密(mi)封(feng)(feng)環的接觸端面(mian)在密(mi)封(feng)(feng)流體壓力(li)和彈性元(yuan)件壓緊(jin)力(li)的作用下緊(jin)密(mi)貼(tie)合,并相對滑動而(er)達(da)到密(mi)封(feng)(feng)。工作時...
機(ji)(ji)(ji)械(xie)密封利用機(ji)(ji)(ji)械(xie)方式傳(chuan)(chuan)遞(di)動(dong)(dong)力和運動(dong)(dong)的傳(chuan)(chuan)動(dong)(dong),機(ji)(ji)(ji)械(xie)傳(chuan)(chuan)動(dong)(dong)在機(ji)(ji)(ji)械(xie)工程中應用非(fei)常廣(guang)泛,有多種形式,主要包(bao)括皮帶傳(chuan)(chuan)動(dong)(dong)、齒輪(lun)傳(chuan)(chuan)動(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)、蝸(gua)桿(gan)蝸(gua)輪(lun)傳(chuan)(chuan)動(dong)(dong)、齒輪(lun)齒條(tiao)傳(chuan)(chuan)動(dong)(dong)和螺旋傳(chuan)(chuan)動(dong)(dong)...
由于有氣囊(nang)的(de)存在,氮氣與隔離(li)液(ye)完全(quan)不接觸,避免(mian)了加壓(ya)氣體被隔離(li)液(ye)吸收,使(shi)填(tian)料(liao)改集式密封(feng)可以(yi)用于液(ye)力透平等(deng)高壓(ya)操作工況,但是由于隔離(li)液(ye)是在換(huan)熱器的(de)盤管中流動(dong),因此...
