蕭縣機械密封的這三個功能一定要了解
機械密(mi)封包括壓力控制、溫度控制、流體替換(堵(du)塞)和雜質去(qu)除系(xi)統(tong)(tong)。在(zai)機械密(mi)封系(xi)統(tong)(tong)中,上述系(xi)統(tong)(tong)并(bing)不同時(shi)包括在(zai)內。密(mi)封系(xi)統(tong)(tong)的選(xuan)擇主(zhu)要(yao)取(qu)決于主(zhu)密(mi)封件(jian)的應用范圍。例如,如...

雙端面小彈簧平(ping)衡型密封(feng)所用(yong)摩擦(ca)(ca)副材料由動環和(he)靜環所組成(cheng)的摩擦(ca)(ca)副是(shi)機械密封(feng)重要的零件,從理論上講,為了減少機械密封(feng)的磨損量,應該(gai)在合(he)理的動力流體潤滑條件下工(gong)作(zuo)運(yun)轉...
我們使(shi)用泵(beng)過程中總會遇到密(mi)封膠(jiao)圈(quan)損壞的情況,一(yi)旦損壞就要進(jin)行更換,作為(wei)一(yi)個(ge)工程技術人員(yuan)首先要分辨自(zi)己的泵(beng)到底(di)是哪種型號(hao),才能(neng)購買(mai)到相(xiang)應口徑的機械密(mi)封,由于在市場...
在使用過程中,大多數機械密封(feng)都屬于(yu)接(jie)(jie)觸式密封(feng),其機理(li)是靠動密封(feng)環與靜密封(feng)環的接(jie)(jie)觸端面在密封(feng)流體(ti)壓力和(he)彈性元(yuan)件壓緊力的作用下緊密貼合,并相對滑(hua)動而達(da)到(dao)密封(feng)。工作時...
