原平機械密封的這三個功能一定要了解
機械(xie)密封包括壓力控(kong)制(zhi)、溫度控(kong)制(zhi)、流體替換(huan)(堵塞)和雜質去除系(xi)(xi)統(tong)。在(zai)機械(xie)密封系(xi)(xi)統(tong)中,上述(shu)系(xi)(xi)統(tong)并(bing)不同時包括在(zai)內。密封系(xi)(xi)統(tong)的(de)選擇主要取決于主密封件的(de)應用范圍。例(li)如(ru),如(ru)...

雙端面小(xiao)彈簧平衡(heng)型密封所用(yong)摩(mo)擦副材料由動(dong)環和(he)靜(jing)環所組成的(de)摩(mo)擦副是機(ji)械密封重要的(de)零件,從(cong)理(li)論上講(jiang),為了減少(shao)機(ji)械密封的(de)磨損量,應(ying)該(gai)在合理(li)的(de)動(dong)力流體潤滑條件下(xia)工(gong)作運轉...
我們使用泵(beng)過(guo)程中總(zong)會遇到密(mi)封膠圈損(sun)壞的(de)情況,一(yi)旦損(sun)壞就要(yao)(yao)進行更換,作為一(yi)個工(gong)程技(ji)術人員首先要(yao)(yao)分辨自(zi)己的(de)泵(beng)到底是哪種型(xing)號,才(cai)能購買到相應(ying)口徑的(de)機械密(mi)封,由于(yu)在市場...
在使(shi)用(yong)過程中,大多數機(ji)械(xie)密(mi)封(feng)都屬于接(jie)(jie)觸式密(mi)封(feng),其機(ji)理是靠動密(mi)封(feng)環與靜密(mi)封(feng)環的接(jie)(jie)觸端面在密(mi)封(feng)流體壓力(li)和彈(dan)性元件壓緊力(li)的作(zuo)用(yong)下(xia)緊密(mi)貼(tie)合(he),并相對(dui)滑動而達到密(mi)封(feng)。工作(zuo)時...
