烏什機械密封對密封環有哪些要求?

  烏什機械密封又叫端面(mian)密(mi)(mi)封,在(zai)(zai)有關標準(zhun)中是這樣解說的(de):由至少(shao)一(yi)對垂(chui)直于(yu)旋轉(zhuan)軸線的(de)端面(mian)在(zai)(zai)流體(ti)壓力(li)和補償機(ji)構彈力(li)的(de)作(zuo)用以及輔助密(mi)(mi)封的(de)配(pei)合下保持貼合并(bing)相對滑(hua)動(dong)而(er)構成的(de)防止流體(ti)泄(xie)漏的(de)裝(zhuang)置。


  烏什機械密封自身壓(ya)力增(zeng)(zeng)壓(ya)系統結構包(bao)括出水(shui)(shui)(shui)(shui)口、固(gu)(gu)定(ding)法蘭、泵(beng)體、增(zeng)(zeng)壓(ya)裝置(zhi)(zhi)、電機轉子(zi)、吊(diao)環、防護罩、水(shui)(shui)(shui)(shui)泵(beng)、固(gu)(gu)定(ding)基座(zuo)、底座(zuo)、加固(gu)(gu)件(jian)(jian)、控(kong)制(zhi)閥、緊(jin)固(gu)(gu)件(jian)(jian),所述出水(shui)(shui)(shui)(shui)口與(yu)(yu)固(gu)(gu)定(ding)法蘭相(xiang)(xiang)連(lian)(lian)(lian)(lian)(lian)接(jie),泵(beng)體與(yu)(yu)增(zeng)(zeng)壓(ya)裝置(zhi)(zhi)相(xiang)(xiang)連(lian)(lian)(lian)(lian)(lian)接(jie),增(zeng)(zeng)壓(ya)裝置(zhi)(zhi)由進水(shui)(shui)(shui)(shui)口、水(shui)(shui)(shui)(shui)管、負(fu)(fu)壓(ya)室(shi)、平(ping)衡固(gu)(gu)定(ding)盤(pan)、緊(jin)固(gu)(gu)支(zhi)(zhi)架組成,進水(shui)(shui)(shui)(shui)口與(yu)(yu)水(shui)(shui)(shui)(shui)管相(xiang)(xiang)連(lian)(lian)(lian)(lian)(lian)接(jie),水(shui)(shui)(shui)(shui)管與(yu)(yu)負(fu)(fu)壓(ya)室(shi)相(xiang)(xiang)連(lian)(lian)(lian)(lian)(lian)接(jie),負(fu)(fu)壓(ya)室(shi)通過平(ping)衡固(gu)(gu)定(ding)盤(pan)保持平(ping)衡,緊(jin)固(gu)(gu)支(zhi)(zhi)架與(yu)(yu)泵(beng)體固(gu)(gu)定(ding)連(lian)(lian)(lian)(lian)(lian)接(jie),防護罩與(yu)(yu)水(shui)(shui)(shui)(shui)泵(beng)相(xiang)(xiang)連(lian)(lian)(lian)(lian)(lian)接(jie),水(shui)(shui)(shui)(shui)泵(beng)與(yu)(yu)固(gu)(gu)定(ding)基座(zuo)相(xiang)(xiang)連(lian)(lian)(lian)(lian)(lian)接(jie),固(gu)(gu)定(ding)基座(zuo)與(yu)(yu)底座(zuo)緊(jin)固(gu)(gu)連(lian)(lian)(lian)(lian)(lian)接(jie),底座(zuo)上設有加固(gu)(gu)件(jian)(jian),緊(jin)固(gu)(gu)件(jian)(jian)與(yu)(yu)底座(zuo)固(gu)(gu)定(ding)連(lian)(lian)(lian)(lian)(lian)接(jie)。


  動環和靜環的總稱叫做密封環,是構成烏什機械密封件主要的元件。密封環在很大程度上決定了烏什機械密封件的使用性能和壽命,所以烏什機械密封件對密封(feng)環(huan)有一些特定(ding)的(de)要求(qiu)。


  一(yi)、密封(feng)環(huan)要(yao)容易加工制造


  二、安(an)裝和維修要(yao)方便,價格要(yao)低(di)廉。


  三、密封環要(yao)有(you)(you)良好的(de)耐(nai)熱(re)沖(chong)擊(ji)(ji)能力,因此(ci)材(cai)料要(yao)有(you)(you)較高的(de)導(dao)熱(re)系(xi)數(shu)和(he)較小的(de)線(xian)膨脹(zhang)系(xi)數(shu),承受(shou)熱(re)沖(chong)擊(ji)(ji)時不至于開裂。


  四、密(mi)封環(huan)要(yao)有良好(hao)的自潤滑性,防止工作(zuo)中(zhong)發生短時間的干摩擦,不損傷密(mi)封端面。因此,密(mi)封環(huan)材(cai)料與密(mi)封流體還要(yao)有很好(hao)的浸潤性。


  五、結構簡單


  密(mi)封(feng)環結(jie)構簡單對稱(cheng),優先考慮用(yong)(yong)整體型結(jie)構,也可采用(yong)(yong)組(zu)合式密(mi)封(feng)環,盡(jin)量避(bi)免用(yong)(yong)密(mi)封(feng)端面噴涂式結(jie)構。


  六、有足夠的強度(du)和剛度(du)


  烏什機械密封件(jian)在(zai)工作(zuo)條件(jian)下不損壞,變形應盡(jin)量的(de)小,工作(zuo)條件(jian)波動時仍能保持密(mi)封性(xing)。尤其是密(mi)封端(duan)面要有足(zu)夠的(de)強度以及(ji)一定的(de)耐(nai)腐(fu)蝕能力,保證產(chan)品的(de)使(shi)用壽(shou)命。
