沿灘機械密封的這三個功能一定要了解
機(ji)械密(mi)(mi)封包括壓力控制、溫度控制、流體替(ti)換(huan)(堵塞)和雜質(zhi)去除系(xi)統(tong)(tong)。在機(ji)械密(mi)(mi)封系(xi)統(tong)(tong)中(zhong),上述系(xi)統(tong)(tong)并不同時包括在內。密(mi)(mi)封系(xi)統(tong)(tong)的選(xuan)擇主要取決于主密(mi)(mi)封件的應用范圍(wei)。例如(ru),如(ru)...

雙端面小彈簧平衡(heng)型(xing)密(mi)封所(suo)用摩擦副材料由動(dong)(dong)環和靜環所(suo)組成(cheng)的摩擦副是機械(xie)密(mi)封重要的零件(jian),從理論上講,為(wei)了減少(shao)機械(xie)密(mi)封的磨損量,應該在合理的動(dong)(dong)力流體潤滑條件(jian)下工作運(yun)轉...
我們使(shi)用(yong)泵(beng)過程中總會遇(yu)到密封(feng)膠圈損(sun)(sun)壞的情況,一旦損(sun)(sun)壞就要進行更換,作為(wei)一個工程技術人員(yuan)首先(xian)要分辨自己(ji)的泵(beng)到底是(shi)哪種型號(hao),才能購買到相(xiang)應口徑的機械密封(feng),由于在市場(chang)...
在(zai)使用過程(cheng)中,大多數(shu)機(ji)械(xie)密(mi)(mi)封(feng)都屬于接(jie)觸(chu)式密(mi)(mi)封(feng),其機(ji)理(li)是靠動密(mi)(mi)封(feng)環與靜密(mi)(mi)封(feng)環的接(jie)觸(chu)端(duan)面在(zai)密(mi)(mi)封(feng)流體壓(ya)力和彈性元(yuan)件壓(ya)緊(jin)力的作用下緊(jin)密(mi)(mi)貼合,并(bing)相對(dui)滑動而達到密(mi)(mi)封(feng)。工作時...
