南口街道機械密封的這三個功能一定要了解
機械密封包括壓力控制(zhi)、溫度控制(zhi)、流體替換(堵(du)塞)和雜(za)質去除系(xi)(xi)統(tong)。在機械密封系(xi)(xi)統(tong)中,上述系(xi)(xi)統(tong)并(bing)不同時(shi)包括在內。密封系(xi)(xi)統(tong)的選擇(ze)主(zhu)(zhu)要取(qu)決于主(zhu)(zhu)密封件的應用范圍。例如,如...

雙(shuang)端面(mian)小彈簧平衡型密(mi)封(feng)所用摩(mo)擦(ca)副(fu)(fu)材料由(you)動(dong)(dong)環(huan)和靜環(huan)所組成的(de)(de)摩(mo)擦(ca)副(fu)(fu)是機(ji)械(xie)密(mi)封(feng)重要(yao)的(de)(de)零(ling)件,從理(li)論上(shang)講,為(wei)了(le)減(jian)少機(ji)械(xie)密(mi)封(feng)的(de)(de)磨損量,應該在合理(li)的(de)(de)動(dong)(dong)力流體潤滑條件下工(gong)作運轉...
我們使用泵過程中總會遇(yu)到(dao)密(mi)封膠(jiao)圈(quan)損(sun)壞的情況(kuang),一旦損(sun)壞就(jiu)要(yao)進行更換,作為一個工程技術人員首先要(yao)分辨自己的泵到(dao)底是哪(na)種型號,才能(neng)購買到(dao)相應口徑的機械密(mi)封,由于在市場...
在使用過程中(zhong),大多數機(ji)械密(mi)(mi)封(feng)都屬于接(jie)觸式(shi)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(de)接(jie)觸端面(mian)在密(mi)(mi)封(feng)流(liu)體壓力(li)(li)和彈性元(yuan)件(jian)壓緊力(li)(li)的(de)作(zuo)用下緊密(mi)(mi)貼合,并相對滑(hua)動而達到密(mi)(mi)封(feng)。工(gong)作(zuo)時...
