富順機械密封的這三個功能一定要了解
機(ji)械(xie)密封包(bao)括壓(ya)力控制、溫度控制、流(liu)體(ti)替換(堵塞)和雜質去(qu)除系統(tong)。在機(ji)械(xie)密封系統(tong)中(zhong),上述(shu)系統(tong)并不同(tong)時(shi)包(bao)括在內。密封系統(tong)的選擇主要取決于主密封件的應用范(fan)圍。例如,如...

雙端(duan)面(mian)小彈簧平衡型密封(feng)(feng)所用(yong)摩擦(ca)副材料由(you)動環和靜(jing)環所組成(cheng)的摩擦(ca)副是機械(xie)密封(feng)(feng)重要(yao)的零件(jian)(jian),從理論上講,為了減少機械(xie)密封(feng)(feng)的磨(mo)損量,應(ying)該在合(he)理的動力流體潤(run)滑條件(jian)(jian)下工作運(yun)轉...
我們使用泵過(guo)程(cheng)中(zhong)總(zong)會遇到密封膠圈損壞的情況,一(yi)旦損壞就要進行更換,作為(wei)一(yi)個工程(cheng)技術人員首先要分(fen)辨自己(ji)的泵到底(di)是(shi)哪種(zhong)型號,才(cai)能(neng)購(gou)買到相應口徑(jing)的機械密封,由(you)于在市場(chang)...
在(zai)使用過程中,大多數機(ji)械密(mi)(mi)封(feng)(feng)都(dou)屬于接觸式密(mi)(mi)封(feng)(feng),其機(ji)理是靠動密(mi)(mi)封(feng)(feng)環與(yu)靜密(mi)(mi)封(feng)(feng)環的接觸端(duan)面(mian)在(zai)密(mi)(mi)封(feng)(feng)流體壓(ya)力(li)和(he)彈(dan)性元件壓(ya)緊力(li)的作用下(xia)緊密(mi)(mi)貼合,并相對滑(hua)動而達到密(mi)(mi)封(feng)(feng)。工(gong)作時...
機(ji)械(xie)(xie)密封利用機(ji)械(xie)(xie)方式傳(chuan)(chuan)遞動(dong)(dong)力和運(yun)動(dong)(dong)的傳(chuan)(chuan)動(dong)(dong),機(ji)械(xie)(xie)傳(chuan)(chuan)動(dong)(dong)在機(ji)械(xie)(xie)工程中應用非常廣泛,有(you)多(duo)種形式,主要包括皮帶傳(chuan)(chuan)動(dong)(dong)、齒(chi)輪傳(chuan)(chuan)動(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)動(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)(chuan)動(dong)(dong)和螺旋傳(chuan)(chuan)動(dong)(dong)...
由于有(you)氣(qi)囊的存在,氮氣(qi)與(yu)隔(ge)離液完全不接(jie)觸(chu),避免了加(jia)壓氣(qi)體被隔(ge)離液吸收,使填料改集(ji)式密(mi)封可以用(yong)于液力透平(ping)等高(gao)壓操作工(gong)況,但是(shi)由于隔(ge)離液是(shi)在換熱(re)器的盤管中(zhong)流動,因此...
