羅平機械密封的這三個功能一定要了解
機械密封(feng)包括壓力控制、溫度控制、流體替換(huan)(堵(du)塞)和雜質去除系統(tong)(tong)(tong)。在(zai)機械密封(feng)系統(tong)(tong)(tong)中,上述(shu)系統(tong)(tong)(tong)并不(bu)同時包括在(zai)內。密封(feng)系統(tong)(tong)(tong)的選擇主要取(qu)決于主密封(feng)件的應用(yong)范圍。例如,如...

雙(shuang)端面(mian)小彈簧平(ping)衡型密(mi)封所用摩擦副材料(liao)由動環(huan)和(he)靜環(huan)所組成的(de)(de)摩擦副是機(ji)械(xie)(xie)密(mi)封重要的(de)(de)零件,從理(li)論上(shang)講,為(wei)了減少機(ji)械(xie)(xie)密(mi)封的(de)(de)磨(mo)損量,應(ying)該在合(he)理(li)的(de)(de)動力流體潤滑條件下工作運轉(zhuan)...
我(wo)們(men)使(shi)用泵過程(cheng)中總會遇到密(mi)封(feng)膠(jiao)圈(quan)損(sun)壞(huai)的情況,一旦(dan)損(sun)壞(huai)就要(yao)進行更(geng)換,作為一個工程(cheng)技術人員首先要(yao)分辨自己的泵到底是哪(na)種型號,才能購買(mai)到相(xiang)應口徑的機械密(mi)封(feng),由于在(zai)市場...
在使(shi)用(yong)(yong)過程中,大多數機械密(mi)封(feng)都屬(shu)于接觸式密(mi)封(feng),其機理(li)是(shi)靠動密(mi)封(feng)環與靜密(mi)封(feng)環的接觸端面(mian)在密(mi)封(feng)流(liu)體壓力(li)和彈性元件壓緊力(li)的作(zuo)用(yong)(yong)下緊密(mi)貼合,并(bing)相對(dui)滑動而達到(dao)密(mi)封(feng)。工作(zuo)時...
機(ji)械密(mi)封(feng)利用機(ji)械方式傳遞動(dong)(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)(dong)的傳動(dong)(dong)(dong)(dong)(dong),機(ji)械傳動(dong)(dong)(dong)(dong)(dong)在(zai)機(ji)械工程中應用非常廣泛,有(you)多種形式,主(zhu)要包括皮帶(dai)傳動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪傳動(dong)(dong)(dong)(dong)(dong)、鏈傳動(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪傳動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪齒(chi)條(tiao)傳動(dong)(dong)(dong)(dong)(dong)和螺旋傳動(dong)(dong)(dong)(dong)(dong)...
由于有氣(qi)囊(nang)的(de)存在(zai),氮氣(qi)與(yu)隔離(li)液完全不接觸(chu),避免了加壓氣(qi)體(ti)被隔離(li)液吸收,使(shi)填(tian)料改集式密(mi)封可以(yi)用(yong)于液力(li)透平等高壓操作工況,但是由于隔離(li)液是在(zai)換(huan)熱(re)器(qi)的(de)盤管中流(liu)動(dong),因此...
