博爾塔拉機械密封又(you)叫(jiao)端面密(mi)封(feng)，在有關標(biao)準(zhun)中是這樣解說(shuo)的(de)：由至少一對(dui)垂直于旋轉軸線的(de)端面在流體壓力(li)(li)和補償(chang)機構彈(dan)力(li)(li)的(de)作用(yong)以及輔(fu)助(zhu)密(mi)封(feng)的(de)配合下(xia)保(bao)持貼合并相對(dui)滑(hua)動而構成的(de)防止流體泄(xie)漏的(de)裝置。

　　動環和靜環的總稱叫做密封環，是構成博爾塔拉機械密封件主要的元件。密封環在很大程度上決定了博爾塔拉機械密封件的使用性能和壽命，所以博爾塔拉機械密封件(jian)對(dui)密封環有一些特定的要求。

　　一、密封環要容易加工制(zhi)造

　　二、安裝和維修要(yao)方便，價格要(yao)低廉。

　　三、密(mi)封(feng)環要(yao)有良好的耐熱(re)沖擊能力，因此材料要(yao)有較高的導熱(re)系數(shu)和較小的線膨脹(zhang)系數(shu)，承受熱(re)沖擊時不至(zhi)于開裂。

　　四、密(mi)封(feng)環要(yao)有良好的(de)自潤(run)滑性，防(fang)止工作中發生短時間的(de)干摩擦，不損傷密(mi)封(feng)端面。因此，密(mi)封(feng)環材料與密(mi)封(feng)流體(ti)還要(yao)有很(hen)好的(de)浸潤(run)性。

　　五、結構簡單

　　密(mi)(mi)封(feng)環結構(gou)(gou)簡(jian)單對稱，優先考(kao)慮用(yong)整體(ti)型結構(gou)(gou)，也可(ke)采用(yong)組(zu)合式密(mi)(mi)封(feng)環，盡量(liang)避免用(yong)密(mi)(mi)封(feng)端面噴(pen)涂式結構(gou)(gou)。

　　六、有足夠的強度(du)和剛度(du)

　　博爾塔拉機械密封件(jian)在工作條(tiao)(tiao)件(jian)下不損壞，變形應盡(jin)量的小，工作條(tiao)(tiao)件(jian)波動時仍(reng)能保持密(mi)(mi)封(feng)性。尤其是密(mi)(mi)封(feng)端面要有足夠的強度以及(ji)一(yi)定的耐腐蝕能力，保證產品(pin)的使用壽命。
