孝感機械密封的這三個功能一定要了解
機械(xie)密封包括壓力控(kong)制、溫度控(kong)制、流體替換(堵塞)和雜質去除系(xi)(xi)統(tong)(tong)。在機械(xie)密封系(xi)(xi)統(tong)(tong)中，上(shang)述系(xi)(xi)統(tong)(tong)并不(bu)同時包括在內。密封系(xi)(xi)統(tong)(tong)的選擇主要取決于主密封件的應用范(fan)圍。例如，如...

雙端面小(xiao)彈簧平衡型密(mi)封所用摩(mo)擦副材料由(you)動(dong)環(huan)和靜環(huan)所組(zu)成的摩(mo)擦副是(shi)機械密(mi)封重要(yao)的零件，從理(li)論(lun)上(shang)講，為了減少機械密(mi)封的磨損量(liang)，應該在合理(li)的動(dong)力流體潤滑條件下(xia)工作運轉...
我(wo)們使(shi)用泵過程(cheng)中(zhong)總會遇到(dao)密(mi)封膠(jiao)圈損壞的情況，一旦損壞就要進行(xing)更(geng)換，作(zuo)為一個工程(cheng)技術人員首(shou)先(xian)要分辨自(zi)己的泵到(dao)底是哪種型號，才能購買到(dao)相應口徑的機械密(mi)封，由于(yu)在市(shi)場(chang)...
在使(shi)用(yong)過程中，大多(duo)數機(ji)械密(mi)封(feng)都(dou)屬(shu)于接(jie)觸式密(mi)封(feng)，其機(ji)理是靠動密(mi)封(feng)環(huan)與靜密(mi)封(feng)環(huan)的(de)(de)接(jie)觸端面在密(mi)封(feng)流體壓力和彈性元件(jian)壓緊力的(de)(de)作用(yong)下(xia)緊密(mi)貼(tie)合，并相對滑(hua)動而達到密(mi)封(feng)。工(gong)作時(shi)...
機械密封利用機械方式傳(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong)(dong)，機械傳(chuan)(chuan)動(dong)(dong)(dong)(dong)在機械工程中應(ying)用非常廣泛，有多種形式，主(zhu)要(yao)包括皮帶傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)動(dong)(dong)(dong)(dong)...
由(you)于(yu)(yu)有氣(qi)囊的存(cun)在，氮氣(qi)與隔(ge)離液完全不接觸，避(bi)免了加壓(ya)氣(qi)體被(bei)隔(ge)離液吸(xi)收，使填料(liao)改集式密(mi)封可以用于(yu)(yu)液力透平等高(gao)壓(ya)操作工況(kuang)，但是(shi)(shi)由(you)于(yu)(yu)隔(ge)離液是(shi)(shi)在換熱器(qi)的盤(pan)管(guan)中流動，因此...
