額敏機械密封的這三個功能一定要了解
機械(xie)密封包(bao)括壓力(li)控制(zhi)、溫度控制(zhi)、流體(ti)替(ti)換(huan)(堵塞(sai))和雜(za)質去除系(xi)統(tong)(tong)。在機械(xie)密封系(xi)統(tong)(tong)中，上述(shu)系(xi)統(tong)(tong)并不同(tong)時包(bao)括在內。密封系(xi)統(tong)(tong)的選擇主(zhu)要取決于主(zhu)密封件的應用范圍。例(li)如，如...

雙端面小彈簧平衡型密(mi)封(feng)所用摩擦副材(cai)料由動環和靜(jing)環所組成的摩擦副是機械密(mi)封(feng)重要的零件，從(cong)理論(lun)上講，為了減少機械密(mi)封(feng)的磨損量，應(ying)該在合理的動力(li)流體潤滑條件下工作運(yun)轉...
我們使用泵過程中總會(hui)遇到密(mi)封(feng)膠圈損壞的情(qing)況，一(yi)旦損壞就(jiu)要進行更換，作為一(yi)個工程技術人(ren)員首先(xian)要分(fen)辨自己(ji)的泵到底是(shi)哪種型號，才能購買(mai)到相應口徑的機(ji)械密(mi)封(feng)，由于(yu)在市場(chang)...
在(zai)使用(yong)過程中，大多數機械密(mi)(mi)封(feng)(feng)都屬(shu)于接觸(chu)式密(mi)(mi)封(feng)(feng)，其機理(li)是靠(kao)動密(mi)(mi)封(feng)(feng)環(huan)與靜密(mi)(mi)封(feng)(feng)環(huan)的接觸(chu)端面在(zai)密(mi)(mi)封(feng)(feng)流體壓力和彈(dan)性元件壓緊力的作用(yong)下緊密(mi)(mi)貼合，并(bing)相(xiang)對滑動而達(da)到(dao)密(mi)(mi)封(feng)(feng)。工作時...
機(ji)械密封利用機(ji)械方式傳(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和運動(dong)(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong)(dong)，機(ji)械傳(chuan)(chuan)動(dong)(dong)(dong)(dong)在(zai)機(ji)械工程中應用非常廣泛，有多種形式，主要(yao)包括(kuo)皮帶傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)(chuan)動(dong)(dong)(dong)(dong)和螺旋傳(chuan)(chuan)動(dong)(dong)(dong)(dong)...
由于(yu)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(bi)免了加壓(ya)(ya)氣(qi)體被隔(ge)離液吸收，使填料改集(ji)式密封可以用(yong)于(yu)液力透平等高壓(ya)(ya)操作工況，但(dan)是(shi)由于(yu)隔(ge)離液是(shi)在換熱器的盤管(guan)中流動，因此(ci)...
