昌寧機械密封的這三個功能一定要了解
機(ji)械(xie)密(mi)封(feng)(feng)包括壓力控制、溫度控制、流體替換(huan)(堵塞)和雜質去除系統。在機(ji)械(xie)密(mi)封(feng)(feng)系統中,上述(shu)系統并不同時包括在內(nei)。密(mi)封(feng)(feng)系統的(de)選(xuan)擇主(zhu)要(yao)取決于主(zhu)密(mi)封(feng)(feng)件(jian)的(de)應用范圍。例如,如...

雙端面小彈簧平衡型密(mi)封所用摩擦(ca)副(fu)材(cai)料由動環和(he)靜(jing)環所組成的(de)(de)摩擦(ca)副(fu)是機(ji)械(xie)密(mi)封重要的(de)(de)零件(jian),從理論上講,為(wei)了(le)減少(shao)機(ji)械(xie)密(mi)封的(de)(de)磨損量,應該(gai)在合理的(de)(de)動力流(liu)體潤滑(hua)條件(jian)下工作運轉...
我們使用泵過程中總(zong)會遇到密封膠圈損壞的情況(kuang),一旦(dan)損壞就要進行更換,作為一個工程技術人員首(shou)先要分辨自己的泵到底是哪(na)種型號,才能購買到相應口徑的機械密封,由于在市場...
在使用過程中,大(da)多(duo)數機械密封(feng)(feng)都屬于接觸(chu)式密封(feng)(feng),其機理是(shi)靠動密封(feng)(feng)環與靜密封(feng)(feng)環的接觸(chu)端面在密封(feng)(feng)流體壓力(li)和彈性元件(jian)壓緊力(li)的作用下緊密貼合(he),并相(xiang)對(dui)滑動而達到密封(feng)(feng)。工作時...
機(ji)械密封利用(yong)機(ji)械方式傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong),機(ji)械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在機(ji)械工(gong)程(cheng)中應用(yong)非常廣泛,有多種(zhong)形式,主(zhu)要包括皮帶(dai)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)螺旋(xuan)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)...
由于(yu)(yu)有氣囊(nang)的存在(zai),氮氣與隔(ge)離(li)液(ye)完(wan)全不(bu)接(jie)觸,避免(mian)了加(jia)壓氣體被(bei)隔(ge)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(cao)作工況(kuang),但是(shi)由于(yu)(yu)隔(ge)離(li)液(ye)是(shi)在(zai)換熱(re)器的盤管中流動,因此...
