云陽機械密封的這三個功能一定要了解
機械(xie)(xie)密(mi)(mi)封(feng)包括壓力控制(zhi)、溫度控制(zhi)、流體替換(堵塞)和雜質去除系(xi)(xi)統(tong)。在機械(xie)(xie)密(mi)(mi)封(feng)系(xi)(xi)統(tong)中,上述系(xi)(xi)統(tong)并不同時包括在內。密(mi)(mi)封(feng)系(xi)(xi)統(tong)的選擇主要取決于主密(mi)(mi)封(feng)件的應用范(fan)圍。例如,如...

雙端面(mian)小彈(dan)簧平(ping)衡(heng)型(xing)密封所用(yong)摩擦副材料(liao)由動環(huan)和(he)靜(jing)環(huan)所組成(cheng)的(de)(de)摩擦副是(shi)機(ji)械(xie)密封重要的(de)(de)零(ling)件(jian),從理(li)論上講,為了減少機(ji)械(xie)密封的(de)(de)磨(mo)損量,應該在合理(li)的(de)(de)動力流體(ti)潤滑條件(jian)下工作(zuo)運轉...
我們使用(yong)泵過程中(zhong)總會遇(yu)到密(mi)封(feng)膠圈損(sun)(sun)壞的情況,一旦損(sun)(sun)壞就要進(jin)行更換,作為一個工程技術(shu)人員首先要分辨自己的泵到底是(shi)哪種型(xing)號,才(cai)能購(gou)買到相應口徑的機(ji)械密(mi)封(feng),由(you)于在(zai)市場...
在使(shi)用過程中,大多數機械(xie)密(mi)(mi)(mi)(mi)(mi)封都屬(shu)于接(jie)觸式密(mi)(mi)(mi)(mi)(mi)封,其(qi)機理是靠動密(mi)(mi)(mi)(mi)(mi)封環(huan)與靜密(mi)(mi)(mi)(mi)(mi)封環(huan)的接(jie)觸端面在密(mi)(mi)(mi)(mi)(mi)封流體(ti)壓(ya)力和彈(dan)性元件壓(ya)緊力的作用下緊密(mi)(mi)(mi)(mi)(mi)貼合,并相(xiang)對滑(hua)動而達到密(mi)(mi)(mi)(mi)(mi)封。工作時...
機(ji)械密封利(li)用機(ji)械方式傳(chuan)(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong),機(ji)械傳(chuan)(chuan)動(dong)(dong)(dong)在機(ji)械工程中應用非常廣泛,有多種(zhong)形式,主要包括皮帶傳(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪傳(chuan)(chuan)動(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)動(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)(chuan)動(dong)(dong)(dong)和螺旋傳(chuan)(chuan)動(dong)(dong)(dong)...
由(you)于(yu)(yu)有氣(qi)囊的存在,氮氣(qi)與隔離(li)液(ye)完全(quan)不接觸,避免了加壓氣(qi)體被隔離(li)液(ye)吸收,使填料改集式密封可以用于(yu)(yu)液(ye)力透平等高壓操作工(gong)況,但是(shi)(shi)由(you)于(yu)(yu)隔離(li)液(ye)是(shi)(shi)在換熱器的盤管(guan)中流(liu)動,因此(ci)...
