寧遠機械密封的這三個功能一定要了解
機械密(mi)封(feng)包括壓(ya)力控(kong)制、溫度控(kong)制、流(liu)體替換(堵塞)和雜質去除系統(tong)。在(zai)(zai)機械密(mi)封(feng)系統(tong)中(zhong),上述系統(tong)并不(bu)同時包括在(zai)(zai)內(nei)。密(mi)封(feng)系統(tong)的選(xuan)擇主要取決于主密(mi)封(feng)件的應用(yong)范(fan)圍。例如(ru),如(ru)...

雙端面小彈簧平衡型密(mi)封(feng)所用摩擦副材料由(you)動環和靜環所組(zu)成的摩擦副是機(ji)械密(mi)封(feng)重要的零件,從理(li)論(lun)上講(jiang),為了減少機(ji)械密(mi)封(feng)的磨損量,應(ying)該在合理(li)的動力(li)流體(ti)潤滑條件下工(gong)作(zuo)運轉(zhuan)...
我們(men)使用泵過程中總會遇到(dao)密封(feng)膠圈損(sun)壞的情況,一旦損(sun)壞就要(yao)進(jin)行更換,作(zuo)為(wei)一個工程技術(shu)人(ren)員首先要(yao)分(fen)辨自己的泵到(dao)底是哪種(zhong)型號,才能購買到(dao)相應口徑的機械密封(feng),由于(yu)在市場...
在(zai)(zai)使(shi)用(yong)(yong)過程中,大多數機械密(mi)(mi)封都(dou)屬于接(jie)觸式密(mi)(mi)封,其(qi)機理是靠(kao)動密(mi)(mi)封環(huan)與靜(jing)密(mi)(mi)封環(huan)的(de)接(jie)觸端面在(zai)(zai)密(mi)(mi)封流體壓力和彈性元件壓緊(jin)力的(de)作用(yong)(yong)下緊(jin)密(mi)(mi)貼(tie)合,并(bing)相對滑動而達到密(mi)(mi)封。工(gong)作時...
