河曲機械密封的這三個功能一定要了解
機(ji)械(xie)密(mi)封(feng)包(bao)括壓(ya)力控制、溫度控制、流體替(ti)換(堵塞)和(he)雜質去除系(xi)統。在機(ji)械(xie)密(mi)封(feng)系(xi)統中(zhong),上述系(xi)統并不同(tong)時(shi)包(bao)括在內。密(mi)封(feng)系(xi)統的選(xuan)擇(ze)主要取決于主密(mi)封(feng)件的應用范(fan)圍。例(li)如,如...

雙端面小(xiao)彈(dan)簧平(ping)衡型(xing)密(mi)封所用摩擦副(fu)材料(liao)由(you)動環(huan)和靜(jing)環(huan)所組成的摩擦副(fu)是機械密(mi)封重(zhong)要的零件,從(cong)理(li)論上(shang)講,為了減(jian)少(shao)機械密(mi)封的磨損(sun)量,應該(gai)在合理(li)的動力流體潤滑(hua)條件下工作運轉...
我們使用泵(beng)過程中總(zong)會遇(yu)到密封膠圈損壞(huai)的(de)情況,一旦損壞(huai)就要進行更換,作為一個工程技術人(ren)員首先要分辨自己的(de)泵(beng)到底(di)是哪(na)種(zhong)型號(hao),才能(neng)購買到相應口(kou)徑的(de)機械密封,由(you)于在(zai)市場...
在使(shi)用過程中,大多數機(ji)(ji)械密封都屬(shu)于接(jie)觸(chu)式密封,其(qi)機(ji)(ji)理是靠動(dong)密封環與靜(jing)密封環的(de)(de)接(jie)觸(chu)端面在密封流體(ti)壓(ya)(ya)力和彈(dan)性(xing)元件(jian)壓(ya)(ya)緊力的(de)(de)作用下緊密貼合,并相對滑動(dong)而達(da)到密封。工(gong)作時...
