機(ji)械(xie)密(mi)封(feng)包(bao)括壓力控制、溫度控制、流(liu)體(ti)替(ti)換(huan)(堵塞)和(he)雜(za)質(zhi)去除系統(tong)。在機(ji)械(xie)密(mi)封(feng)系統(tong)中，上述(shu)系統(tong)并不同(tong)時(shi)包(bao)括在內(nei)。密(mi)封(feng)系統(tong)的選擇主(zhu)要取(qu)決于主(zhu)密(mi)封(feng)件的應用(yong)范圍。例(li)如(ru)，如(ru)...
雙端面小彈簧(huang)平衡(heng)型(xing)密(mi)封所用摩(mo)擦副(fu)材(cai)料由動環和靜環所組(zu)成的(de)摩(mo)擦副(fu)是機械密(mi)封重要的(de)零件，從理論上講(jiang)，為了減少機械密(mi)封的(de)磨損量，應該在合理的(de)動力流體潤滑條件下(xia)工作(zuo)運轉...
我們使用泵(beng)過(guo)程(cheng)中總會遇到(dao)密封膠圈損壞(huai)的(de)情況，一旦損壞(huai)就要(yao)進(jin)行更換(huan)，作為一個工(gong)程(cheng)技術人員(yuan)首先要(yao)分辨自(zi)己的(de)泵(beng)到(dao)底是哪(na)種型(xing)號，才(cai)能購買到(dao)相(xiang)應口徑的(de)機械密封，由于在市場...
在使用(yong)過程中(zhong)，大(da)多數機械密(mi)封(feng)(feng)都屬于接觸式(shi)密(mi)封(feng)(feng)，其機理是(shi)靠(kao)動密(mi)封(feng)(feng)環(huan)與靜密(mi)封(feng)(feng)環(huan)的接觸端面(mian)在密(mi)封(feng)(feng)流體壓力(li)和彈性(xing)元件壓緊(jin)力(li)的作用(yong)下緊(jin)密(mi)貼合(he)，并(bing)相對滑動而達到密(mi)封(feng)(feng)。工(gong)作時...
