遵義機械密封又叫端面(mian)(mian)密封,在(zai)有關標準中是(shi)這(zhe)樣(yang)解說的:由至(zhi)少(shao)一(yi)對垂(chui)直于旋轉軸(zhou)線的端面(mian)(mian)在(zai)流體壓力和(he)補償機(ji)構(gou)彈力的作用(yong)以(yi)及輔助(zhu)密封的配合(he)下保持貼合(he)并相(xiang)對滑動而構(gou)成的防止流體泄漏(lou)的裝(zhuang)置。
遵義機械密封自身壓(ya)力增(zeng)(zeng)壓(ya)系統結構(gou)包括出(chu)水(shui)(shui)口、固(gu)(gu)(gu)定(ding)(ding)(ding)法(fa)蘭(lan)(lan)、泵(beng)(beng)體、增(zeng)(zeng)壓(ya)裝(zhuang)置(zhi)、電機轉子、吊環、防護(hu)罩、水(shui)(shui)泵(beng)(beng)、固(gu)(gu)(gu)定(ding)(ding)(ding)基座(zuo)、底座(zuo)、加(jia)固(gu)(gu)(gu)件、控制閥、緊(jin)固(gu)(gu)(gu)件,所述出(chu)水(shui)(shui)口與(yu)(yu)固(gu)(gu)(gu)定(ding)(ding)(ding)法(fa)蘭(lan)(lan)相(xiang)連(lian)(lian)接(jie),泵(beng)(beng)體與(yu)(yu)增(zeng)(zeng)壓(ya)裝(zhuang)置(zhi)相(xiang)連(lian)(lian)接(jie),增(zeng)(zeng)壓(ya)裝(zhuang)置(zhi)由進(jin)水(shui)(shui)口、水(shui)(shui)管(guan)、負(fu)(fu)壓(ya)室、平衡(heng)(heng)固(gu)(gu)(gu)定(ding)(ding)(ding)盤、緊(jin)固(gu)(gu)(gu)支架組成,進(jin)水(shui)(shui)口與(yu)(yu)水(shui)(shui)管(guan)相(xiang)連(lian)(lian)接(jie),水(shui)(shui)管(guan)與(yu)(yu)負(fu)(fu)壓(ya)室相(xiang)連(lian)(lian)接(jie),負(fu)(fu)壓(ya)室通過平衡(heng)(heng)固(gu)(gu)(gu)定(ding)(ding)(ding)盤保持平衡(heng)(heng),緊(jin)固(gu)(gu)(gu)支架與(yu)(yu)泵(beng)(beng)體固(gu)(gu)(gu)定(ding)(ding)(ding)連(lian)(lian)接(jie),防護(hu)罩與(yu)(yu)水(shui)(shui)泵(beng)(beng)相(xiang)連(lian)(lian)接(jie),水(shui)(shui)泵(beng)(beng)與(yu)(yu)固(gu)(gu)(gu)定(ding)(ding)(ding)基座(zuo)相(xiang)連(lian)(lian)接(jie),固(gu)(gu)(gu)定(ding)(ding)(ding)基座(zuo)與(yu)(yu)底座(zuo)緊(jin)固(gu)(gu)(gu)連(lian)(lian)接(jie),底座(zuo)上(shang)設有(you)加(jia)固(gu)(gu)(gu)件,緊(jin)固(gu)(gu)(gu)件與(yu)(yu)底座(zuo)固(gu)(gu)(gu)定(ding)(ding)(ding)連(lian)(lian)接(jie)。
動環和靜環的總稱叫做密封環,是構成遵義機械密封件主要的元件。密封環在很大程度上決定了遵義機械密封件的使用性能和壽命,所以遵義機械密封件對密封(feng)環有一(yi)些特(te)定的要求。
一、密封環要(yao)容易加(jia)工(gong)制造
二、安裝(zhuang)和維修要(yao)方便,價格要(yao)低廉。
三、密(mi)封環要有良好的耐熱(re)沖擊能(neng)力(li),因此(ci)材料要有較(jiao)高的導熱(re)系數和較(jiao)小(xiao)的線膨脹系數,承受熱(re)沖擊時不(bu)至于開裂。
四、密封(feng)環(huan)要有(you)良(liang)好的自潤(run)滑性(xing),防止工作中(zhong)發生短時間的干摩擦,不損傷密封(feng)端面。因此(ci),密封(feng)環(huan)材料與密封(feng)流體還要有(you)很好的浸潤(run)性(xing)。
五、結構簡單
密(mi)封(feng)環結構簡單對稱(cheng),優先考慮(lv)用(yong)(yong)整(zheng)體型結構,也(ye)可采用(yong)(yong)組(zu)合式密(mi)封(feng)環,盡量(liang)避免用(yong)(yong)密(mi)封(feng)端面噴涂式結構。
六(liu)、有足夠的強度(du)和剛度(du)
遵義機械密封件在(zai)工(gong)作條件下(xia)不損壞(huai),變形應盡量的小,工(gong)作條件波動(dong)時仍(reng)能保持密封(feng)性。尤其是密封(feng)端面要有足(zu)夠的強度以及一(yi)定的耐腐蝕(shi)能力(li),保證產品的使用壽命。
