機械密(mi)封(feng)包(bao)括(kuo)壓力(li)控制、溫(wen)度控制、流(liu)體替(ti)換(堵塞)和雜質(zhi)去(qu)除系(xi)統(tong)(tong)。在機械密(mi)封(feng)系(xi)統(tong)(tong)中，上(shang)述系(xi)統(tong)(tong)并不同時包(bao)括(kuo)在內。密(mi)封(feng)系(xi)統(tong)(tong)的選(xuan)擇主要取決(jue)于主密(mi)封(feng)件(jian)的應用(yong)范圍。例如，如...
雙(shuang)端面(mian)小彈簧平衡型密封所用摩擦(ca)副材料由動(dong)環和(he)靜環所組成的(de)摩擦(ca)副是機(ji)械密封重要的(de)零件，從理(li)(li)論上(shang)講，為(wei)了減少機(ji)械密封的(de)磨損量，應該在合理(li)(li)的(de)動(dong)力(li)流體潤滑條(tiao)件下工作(zuo)運(yun)轉...
我們使用泵過程(cheng)中總會遇到密(mi)封膠圈損(sun)壞的(de)情(qing)況，一旦損(sun)壞就要進行更換，作為(wei)一個工(gong)程(cheng)技(ji)術人(ren)員首先要分(fen)辨自己的(de)泵到底(di)是哪(na)種(zhong)型(xing)號(hao)，才能購買到相應口(kou)徑的(de)機械(xie)密(mi)封，由于在市場...
在使用(yong)過程(cheng)中，大多數機械密(mi)封(feng)(feng)都屬于接(jie)觸(chu)式密(mi)封(feng)(feng)，其機理是靠動密(mi)封(feng)(feng)環(huan)與靜密(mi)封(feng)(feng)環(huan)的(de)(de)接(jie)觸(chu)端面在密(mi)封(feng)(feng)流體壓力和彈性(xing)元件壓緊力的(de)(de)作(zuo)用(yong)下緊密(mi)貼(tie)合，并相對滑動而(er)達到(dao)密(mi)封(feng)(feng)。工作(zuo)時(shi)...
