眉縣機械密封的這三個功能一定要了解
機械(xie)密(mi)封包括壓力控制、溫度控制、流體替換(huan)(堵塞)和雜質去除系(xi)(xi)統(tong)(tong)。在(zai)機械(xie)密(mi)封系(xi)(xi)統(tong)(tong)中,上(shang)述系(xi)(xi)統(tong)(tong)并(bing)不同時包括在(zai)內。密(mi)封系(xi)(xi)統(tong)(tong)的選擇主要取決于主密(mi)封件的應(ying)用范(fan)圍。例如,如...

雙端面小彈簧平衡型密封(feng)所用摩擦副材(cai)料由動(dong)環和靜環所組(zu)成的(de)摩擦副是機械密封(feng)重(zhong)要(yao)的(de)零件(jian),從理論上講,為了減(jian)少機械密封(feng)的(de)磨(mo)損量,應該(gai)在合理的(de)動(dong)力流體潤滑條件(jian)下工作運轉...
我(wo)們使用(yong)泵(beng)(beng)過程(cheng)中總會遇到(dao)密(mi)封(feng)(feng)膠圈(quan)損壞的情況,一(yi)旦損壞就要(yao)進行更換,作為一(yi)個工程(cheng)技術人員首先要(yao)分辨自己的泵(beng)(beng)到(dao)底是(shi)哪種型(xing)號(hao),才能購買到(dao)相(xiang)應(ying)口徑(jing)的機械(xie)密(mi)封(feng)(feng),由(you)于在(zai)市場...
在(zai)使(shi)用過程中,大多(duo)數機械密(mi)(mi)(mi)封(feng)(feng)都屬于接觸式(shi)密(mi)(mi)(mi)封(feng)(feng),其機理(li)是靠(kao)動(dong)密(mi)(mi)(mi)封(feng)(feng)環(huan)與靜密(mi)(mi)(mi)封(feng)(feng)環(huan)的接觸端面在(zai)密(mi)(mi)(mi)封(feng)(feng)流體壓(ya)力(li)和彈性元件壓(ya)緊(jin)力(li)的作(zuo)用下(xia)緊(jin)密(mi)(mi)(mi)貼合,并相對滑動(dong)而(er)達(da)到(dao)密(mi)(mi)(mi)封(feng)(feng)。工作(zuo)時...
機械密封利用(yong)機械方式傳(chuan)遞動(dong)(dong)(dong)(dong)力和運動(dong)(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong)(dong),機械傳(chuan)動(dong)(dong)(dong)(dong)在機械工程中應用(yong)非常(chang)廣泛,有(you)多種(zhong)形(xing)式,主要(yao)包括皮帶傳(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)動(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)齒條(tiao)傳(chuan)動(dong)(dong)(dong)(dong)和螺旋(xuan)傳(chuan)動(dong)(dong)(dong)(dong)...
由(you)于(yu)有氣囊(nang)的(de)存(cun)在(zai),氮氣與(yu)隔離液完全不接觸,避免(mian)了加壓(ya)氣體被隔離液吸收,使填料改(gai)集式密封可以(yi)用于(yu)液力透平等高壓(ya)操(cao)作工況,但是(shi)由(you)于(yu)隔離液是(shi)在(zai)換熱(re)器(qi)的(de)盤(pan)管(guan)中(zhong)流動,因(yin)此...
