達川機械密封的這三個功能一定要了解
機(ji)械密(mi)(mi)封包括(kuo)壓力控(kong)制、溫度控(kong)制、流體(ti)替換(堵塞)和(he)雜質去(qu)除系(xi)統(tong)。在機(ji)械密(mi)(mi)封系(xi)統(tong)中,上述系(xi)統(tong)并(bing)不同時(shi)包括(kuo)在內(nei)。密(mi)(mi)封系(xi)統(tong)的選擇(ze)主要取(qu)決于主密(mi)(mi)封件的應用范圍。例如(ru),如(ru)...

雙端面小彈(dan)簧平衡型密封(feng)(feng)所用(yong)摩擦(ca)副(fu)材(cai)料(liao)由動環和靜(jing)環所組(zu)成的摩擦(ca)副(fu)是機械密封(feng)(feng)重要(yao)的零件(jian),從理論上(shang)講,為了減少(shao)機械密封(feng)(feng)的磨損(sun)量,應該在合(he)理的動力(li)流體(ti)潤(run)滑條件(jian)下(xia)工(gong)作運轉...
我們使用泵過程(cheng)中總會遇到密封(feng)膠圈損(sun)壞的(de)(de)情況,一(yi)(yi)旦(dan)損(sun)壞就要進行更換,作為一(yi)(yi)個工(gong)程(cheng)技術人(ren)員首先(xian)要分(fen)辨自己的(de)(de)泵到底是(shi)哪種(zhong)型(xing)號,才能購(gou)買到相應口(kou)徑的(de)(de)機(ji)械(xie)密封(feng),由于(yu)在市場...
在使(shi)用(yong)過(guo)程中,大多數機械密封都屬(shu)于接(jie)(jie)觸式(shi)密封,其機理是靠動密封環與(yu)靜密封環的接(jie)(jie)觸端面在密封流(liu)體壓(ya)力(li)和彈性元件壓(ya)緊力(li)的作用(yong)下緊密貼合,并相對滑動而達到密封。工作時...
