隨州機械密封的這三個功能一定要了解
機械密封(feng)(feng)包括壓力控制、溫度(du)控制、流(liu)體替(ti)換(堵塞)和雜質去除系(xi)統。在機械密封(feng)(feng)系(xi)統中,上述(shu)系(xi)統并(bing)不同時包括在內。密封(feng)(feng)系(xi)統的選擇(ze)主(zhu)要取決于主(zhu)密封(feng)(feng)件的應用范圍。例如(ru),如(ru)...

雙端面小彈簧(huang)平衡(heng)型密封(feng)所用摩擦副材料由動(dong)環(huan)和靜環(huan)所組成的(de)摩擦副是機械密封(feng)重要的(de)零件,從理(li)(li)論(lun)上講,為了減少(shao)機械密封(feng)的(de)磨損量,應該在合理(li)(li)的(de)動(dong)力流體潤滑條件下工作(zuo)運轉...
我們使(shi)用(yong)泵過程(cheng)中總(zong)會遇(yu)到(dao)密封膠圈(quan)損(sun)壞的情況(kuang),一旦損(sun)壞就要(yao)進(jin)行更換,作(zuo)為一個工程(cheng)技術(shu)人員首先要(yao)分辨(bian)自己的泵到(dao)底是哪種型號,才能購買到(dao)相應口徑的機械密封,由(you)于在市場...
在使用過程中,大多數機(ji)械密(mi)封(feng)(feng)都屬于(yu)接觸式密(mi)封(feng)(feng),其機(ji)理是靠動密(mi)封(feng)(feng)環(huan)與靜密(mi)封(feng)(feng)環(huan)的(de)(de)接觸端面在密(mi)封(feng)(feng)流(liu)體壓力和彈性(xing)元(yuan)件壓緊(jin)力的(de)(de)作(zuo)用下緊(jin)密(mi)貼合,并相(xiang)對滑動而達到(dao)密(mi)封(feng)(feng)。工作(zuo)時...
機(ji)(ji)械(xie)(xie)密封利(li)用機(ji)(ji)械(xie)(xie)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(ji)(ji)械(xie)(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)在機(ji)(ji)械(xie)(xie)工程中應用非常(chang)廣泛,有多種形式,主(zhu)要包括皮(pi)帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)(chi)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(chi)(chi)輪(lun)齒(chi)(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)和螺(luo)旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)...
由于(yu)有氣(qi)囊的存在,氮氣(qi)與隔(ge)離液完(wan)全不(bu)接觸,避免了加壓氣(qi)體被(bei)隔(ge)離液吸(xi)收(shou),使填料(liao)改集式密封可以用于(yu)液力透平等高壓操作(zuo)工(gong)況(kuang),但是(shi)由于(yu)隔(ge)離液是(shi)在換(huan)熱器的盤(pan)管中流動,因此...
