潁上機械密封的這三個功能一定要了解
機(ji)械密(mi)封(feng)包(bao)括壓力控制、溫度控制、流體替換(堵塞(sai))和(he)雜質去除系(xi)統(tong)。在(zai)機(ji)械密(mi)封(feng)系(xi)統(tong)中,上述系(xi)統(tong)并不同時(shi)包(bao)括在(zai)內。密(mi)封(feng)系(xi)統(tong)的(de)選擇主要取決于主密(mi)封(feng)件的(de)應用范圍(wei)。例如(ru),如(ru)...

雙端面小彈簧平衡型(xing)密封(feng)所用摩(mo)擦(ca)副材料由動環(huan)和靜環(huan)所組成的摩(mo)擦(ca)副是機械密封(feng)重要(yao)的零件(jian),從(cong)理論(lun)上講,為了減少(shao)機械密封(feng)的磨(mo)損量,應該在合(he)理的動力流體潤滑(hua)條件(jian)下工(gong)作運轉...
我(wo)們使用泵過程中總(zong)會遇到(dao)(dao)密封膠圈損(sun)壞的情(qing)況,一旦損(sun)壞就要進行更換,作為一個工程技術人員首先要分辨自己的泵到(dao)(dao)底是(shi)哪種(zhong)型號,才能購買到(dao)(dao)相應口徑的機械(xie)密封,由于在市場...
在使用過程中,大多數機械密(mi)(mi)封(feng)(feng)都屬于接觸式(shi)密(mi)(mi)封(feng)(feng),其機理是(shi)靠動密(mi)(mi)封(feng)(feng)環與(yu)靜密(mi)(mi)封(feng)(feng)環的接觸端面在密(mi)(mi)封(feng)(feng)流體(ti)壓(ya)力和(he)彈性元(yuan)件壓(ya)緊(jin)(jin)力的作(zuo)用下緊(jin)(jin)密(mi)(mi)貼合,并相對滑(hua)動而達到密(mi)(mi)封(feng)(feng)。工作(zuo)時(shi)...
機械密封利用機械方式傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong),機械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)在機械工程中(zhong)應用非(fei)常廣(guang)泛,有(you)多種形(xing)式,主要包括(kuo)皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒輪(lun)齒條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)...
由于有氣(qi)囊的存在(zai),氮氣(qi)與(yu)隔(ge)離液(ye)完全不接觸,避免(mian)了加(jia)壓氣(qi)體(ti)被隔(ge)離液(ye)吸(xi)收,使填料(liao)改集式密封可以用于液(ye)力(li)透平(ping)等高壓操作(zuo)工況,但是(shi)由于隔(ge)離液(ye)是(shi)在(zai)換熱器的盤管中流動,因(yin)此...
