泛塞封(feng)(feng)(feng)(feng)(feng)安裝在溝(gou)槽內,四氟外殼受壓(ya), 形成向外的(de)張力, 促使密(mi)封(feng)(feng)(feng)(feng)(feng)唇緊貼密(mi)封(feng)(feng)(feng)(feng)(feng)溝(gou)槽及工作面(mian), 由于彈簧長久給密(mi)封(feng)(feng)(feng)(feng)(feng)唇提供(gong)彈力,能彌補密(mi)封(feng)(feng)(feng)(feng)(feng)磨損和(he)配合(he)零件的(de)偏心, 由此(ci)形成從(cong)真空到(dao)(dao)高(gao)(gao)壓(ya)范(fan)圍內的(de)密(mi)封(feng)(feng)(feng)(feng)(feng)。另外, 流體壓(ya)力對密(mi)封(feng)(feng)(feng)(feng)(feng)唇口施加(jia)應力,壓(ya)力越(yue)大,總的(de)密(mi)封(feng)(feng)(feng)(feng)(feng)壓(ya)力升高(gao)(gao),密(mi)封(feng)(feng)(feng)(feng)(feng)唇與溝(gou)槽及工作面(mian)貼合(he)得越(yue)充(chong)分,由此(ci)形成高(gao)(gao)壓(ya)密(mi)封(feng)(feng)(feng)(feng)(feng)。文章看到(dao)(dao)這(zhe)里,你都了解清楚了嗎?
液(ye)(ye)壓(ya)(ya)沖(chong)擊(ji):產(chan)生(sheng)(sheng)液(ye)(ye)壓(ya)(ya)沖(chong)擊(ji)的(de)(de)因素很多,如挖掘機挖斗(dou)突然碰到石頭,吊機起吊或放下重(zhong)物的(de)(de)瞬間(jian)。除外(wai)在因素外(wai),對于高壓(ya)(ya)大流量液(ye)(ye)壓(ya)(ya)系(xi)統,執行元件換向(xiang)時,如果換向(xiang)閥性(xing)能不太好,很容(rong)易產(chan)生(sheng)(sheng)液(ye)(ye)壓(ya)(ya)沖(chong)擊(ji)。液(ye)(ye)壓(ya)(ya)沖(chong)擊(ji)產(chan)生(sheng)(sheng)的(de)(de)瞬間(jian)高壓(ya)(ya)可能是系(xi)統工作(zuo)壓(ya)(ya)力的(de)(de)幾(ji)倍,這樣高的(de)(de)壓(ya)(ya)力在極短時間(jian)內會將油(you)封撕(si)裂或將其局部(bu)擠入(ru)間(jian)隙之內,造成嚴重(zhong)損(sun)壞。一(yi)般有液(ye)(ye)壓(ya)(ya)沖(chong)擊(ji)的(de)(de)油(you)缸應在活塞桿上(shang)安裝緩(huan)沖(chong)環和擋(dang)圈。緩(huan)沖(chong)環裝在油(you)封的(de)(de)前面吸(xi)收大部(bu)分沖(chong)擊(ji)壓(ya)(ya)力,擋(dang)圈防止油(you)封在高壓(ya)(ya)下擠入(ru)間(jian)隙,根部(bu)被咬壞。
泛塞是(shi)一種U型鐵(tie)氟龍(long)內裝(zhuang)特殊(shu)彈(dan)簧(huang)的(de)密(mi)封(feng)(feng)件(jian),由(you)適當的(de)彈(dan)簧(huang)力加上系統流(liu)體壓力,將密(mi)封(feng)(feng)唇(chun)(面(mian))頂出而輕輕壓住(zhu)被密(mi)封(feng)(feng)的(de)金屬(shu)面(mian)以生成非常優異的(de)密(mi)封(feng)(feng)效(xiao)果。彈(dan)簧(huang)的(de)致動效(xiao)應(ying)可以克服(fu)金屬(shu)配合面(mian)的(de)輕微(wei)偏(pian)心以及密(mi)封(feng)(feng)唇(chun)的(de)磨耗(hao),而持續保有預期的(de)密(mi)封(feng)(feng)性能(neng)。
泛塞(sai)封(feng)(feng)(feng)(feng)Omniseal,又稱彈(dan)(dan)簧(huang)(huang)蓄能(neng)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)圈。是一個由PTFE夾套(tao)及(ji)蓄能(neng)彈(dan)(dan)簧(huang)(huang)組合的壓(ya)力(li)輔(fu)助密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)裝(zhuang)置,夾套(tao)及(ji)蓄能(neng)彈(dan)(dan)簧(huang)(huang)均(jun)具有(you)優(you)異的耐腐蝕能(neng)力(li)。當它(ta)裝(zhuang)在(zai)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)溝槽內,彈(dan)(dan)簧(huang)(huang)受壓(ya),促使夾套(tao)唇邊緊貼密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)溝槽,由此(ci)形(xing)成(cheng)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)。彈(dan)(dan)簧(huang)(huang)給(gei)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)夾套(tao)提供長久的壓(ya)力(li),并彌補材料磨(mo)損及(ji)配合零件(jian)的偏(pian)移或偏(pian)心,系統壓(ya)力(li)也會輔(fu)助密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)夾套(tao)蓄能(neng),通過彈(dan)(dan)簧(huang)(huang)彈(dan)(dan)力(li)和系統壓(ya)力(li),無(wu)論在(zai)高壓(ya)或低壓(ya)下,都可(ke)以實現有(you)效(xiao)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)。
