彈(dan)(dan)簧設置在流體(ti)之內(nei)為(wei)彈(dan)(dan)簧內(nei)置式(shi)(shi)、反之為(wei)彈(dan)(dan)簧外(wai)置式(shi)(shi)按照補償安排彈(dan)(dan)簧的數(shu)量分為(wei)單彈(dan)(dan)簧式(shi)(shi)、多(duo)彈(dan)(dan)簧式(shi)(shi)。
按(an)照(zhao)彈性元件是否隨(sui)軸一(yi)同旋轉分為旋轉式、中止式機械密封。
密封流體(ti)在密封端面(mian)間的(de)泄露(lu)方向如果與軸(zhou)旋轉(zhuan)的(de)離(li)心方向共同則為外流式,HOA軸(zhou)用泛塞封,反之(zhi)為內(nei)流式。
按(an)照密封端(duan)面直(zhi)觸(chu)(chu)摸(mo)摸(mo)與否(fou)分(fen)(fen)為觸(chu)(chu)摸(mo)式(shi)(shi)機械密封,反之為非觸(chu)(chu)摸(mo)式(shi)(shi),其又(you)可分(fen)(fen)為流體靜壓式(shi)(shi)及(ji)流體動壓式(shi)(shi)。
按照(zhao)有否波(bo)紋(wen)管(guan)(guan)(guan)狀況可分(fen)為非波(bo)紋(wen)管(guan)(guan)(guan)式(shi)(shi)波(bo)紋(wen)管(guan)(guan)(guan)式(shi)(shi),后者又可分(fen)為金屬波(bo)紋(wen)管(guan)(guan)(guan)、四氟波(bo)紋(wen)管(guan)(guan)(guan)、橡膠波(bo)紋(wen)管(guan)(guan)(guan)等幾(ji)種。
目前泛(fan)塞(sai)(sai)封(feng)(feng)(feng)在(zai)各種(zhong)設備(bei)上(shang)已經得(de)到(dao)廣泛(fan)選用(yong)(yong)(yong),HVB孔用(yong)(yong)(yong)泛(fan)塞(sai)(sai)封(feng)(feng)(feng),由于(yu)各種(zhong)設備(bei)的(de)(de)使(shi)用(yong)(yong)(yong)環(huan)境(jing)不一樣,設備(bei)商(shang)(shang)在(zai)選用(yong)(yong)(yong)泛(fan)塞(sai)(sai)封(feng)(feng)(feng)的(de)(de)同(tong)時,一定(ding)要(yao)把(ba)各種(zhong)使(shi)用(yong)(yong)(yong)參數描述給泛(fan)塞(sai)(sai)封(feng)(feng)(feng)廠商(shang)(shang),因為使(shi)用(yong)(yong)(yong)環(huan)境(jing)跟(gen)要(yao)求不一樣,選用(yong)(yong)(yong)的(de)(de)材料、彈簧、密(mi)封(feng)(feng)(feng)圈的(de)(de)壓縮率等等都有區(qu)別,這就(jiu)導致一些(xie)廠商(shang)(shang)采購(gou)回來的(de)(de)泛(fan)塞(sai)(sai)封(feng)(feng)(feng)跟(gen)使(shi)用(yong)(yong)(yong)環(huan)境(jing)不符合而產生的(de)(de)泄(xie)漏,主要(yao)參數包括:使(shi)用(yong)(yong)(yong)溫度、動密(mi)封(feng)(feng)(feng)還(huan)(huan)是靜密(mi)封(feng)(feng)(feng)、旋轉用(yong)(yong)(yong)還(huan)(huan)是往(wang)復用(yong)(yong)(yong)、介質、壓力等等。另外安裝溝(gou)槽也必須嚴格按照泛(fan)塞(sai)(sai)封(feng)(feng)(feng)廠家的(de)(de)要(yao)求(光潔度跟(gen)間隙),泛(fan)塞(sai)(sai)封(feng)(feng)(feng),以免造(zao)成泄(xie)漏現象。
