鎮坪機械密封的這三個功能一定要了解
機(ji)(ji)械密(mi)封包括壓力控(kong)制、溫(wen)度控(kong)制、流體替換(堵塞)和(he)雜質去除系(xi)統(tong)。在機(ji)(ji)械密(mi)封系(xi)統(tong)中,上述系(xi)統(tong)并不同時包括在內。密(mi)封系(xi)統(tong)的(de)選擇主要取決于主密(mi)封件的(de)應用(yong)范圍。例如,如...

雙端面小彈簧平衡型(xing)密封(feng)所(suo)用摩擦副材料(liao)由動(dong)環和靜環所(suo)組成的(de)摩擦副是(shi)機械(xie)密封(feng)重要的(de)零件(jian),從理論上講(jiang),為(wei)了(le)減少機械(xie)密封(feng)的(de)磨損量,應(ying)該在合理的(de)動(dong)力流(liu)體(ti)潤滑條(tiao)件(jian)下工作運轉...
我(wo)們使(shi)用泵(beng)過(guo)程(cheng)中(zhong)總會遇到(dao)(dao)密(mi)封(feng)膠圈損壞(huai)的(de)(de)情況,一(yi)旦損壞(huai)就(jiu)要進行更換,作為一(yi)個工程(cheng)技(ji)術人員(yuan)首先要分辨自己的(de)(de)泵(beng)到(dao)(dao)底是哪(na)種型號,才能購買到(dao)(dao)相應口(kou)徑(jing)的(de)(de)機(ji)械密(mi)封(feng),由于在(zai)市場...
在(zai)使用(yong)過(guo)程中,大多數機(ji)械(xie)密(mi)(mi)封(feng)都屬(shu)于接觸式密(mi)(mi)封(feng),其機(ji)理是(shi)靠動(dong)密(mi)(mi)封(feng)環與靜密(mi)(mi)封(feng)環的接觸端面在(zai)密(mi)(mi)封(feng)流體壓力(li)和彈性元件壓緊(jin)力(li)的作用(yong)下緊(jin)密(mi)(mi)貼合,并相對滑動(dong)而達到密(mi)(mi)封(feng)。工作時...
