廣安機械密封的這三個功能一定要了解
機械密(mi)封包括壓力控制、溫度(du)控制、流體替換(堵塞)和雜質去除系(xi)統(tong)。在(zai)機械密(mi)封系(xi)統(tong)中(zhong),上述系(xi)統(tong)并不同時(shi)包括在(zai)內(nei)。密(mi)封系(xi)統(tong)的選擇主(zhu)(zhu)要取(qu)決于主(zhu)(zhu)密(mi)封件(jian)的應用范圍。例如,如...

雙端(duan)面小彈(dan)簧平衡(heng)型密(mi)封(feng)所用摩(mo)擦副材料(liao)由動(dong)環和靜環所組成的摩(mo)擦副是(shi)機械密(mi)封(feng)重要的零件,從理論(lun)上講(jiang),為了減(jian)少(shao)機械密(mi)封(feng)的磨損(sun)量,應該在合(he)理的動(dong)力流體(ti)潤(run)滑條件下工作運轉...
我們使用泵(beng)過(guo)程中總會遇到(dao)(dao)密封(feng)膠圈損壞的(de)情況,一旦損壞就要(yao)進行(xing)更(geng)換,作為一個工程技術人(ren)員首先要(yao)分(fen)辨自己的(de)泵(beng)到(dao)(dao)底是哪種型號(hao),才能購買到(dao)(dao)相應(ying)口徑的(de)機械密封(feng),由于在(zai)市場...
在使(shi)用過程中,大多數機械密(mi)(mi)封(feng)(feng)都屬于接觸式密(mi)(mi)封(feng)(feng),其機理是靠(kao)動(dong)密(mi)(mi)封(feng)(feng)環(huan)與(yu)靜密(mi)(mi)封(feng)(feng)環(huan)的接觸端面在密(mi)(mi)封(feng)(feng)流體(ti)壓力(li)和彈性元件壓緊力(li)的作(zuo)用下(xia)緊密(mi)(mi)貼合,并相對滑動(dong)而(er)達(da)到密(mi)(mi)封(feng)(feng)。工(gong)作(zuo)時...
