和田市機械密封又叫端面密封,在有關標準中是這樣定義的:由至少一對垂直于旋轉軸線的端面在流體壓力和補償機構彈力的作用以及輔助密封的配合下保持貼合并相對滑動而構成的防止流體泄漏的裝置。帶有平衡罐的自身壓力增壓系統是一種壓力傳遞機構,用于雙端面和田市機械密封,以解決現有(you)的(de)循環(huan)(huan)水泵的(de)部分(fen)揚(yang)程不(bu)能克服系統的(de)阻力(li),在循環(huan)(huan)泵流量不(bu)變(bian)的(de)情況(kuang)下,一旦循環(huan)(huan)泵的(de)揚(yang)程提高(gao),則循環(huan)(huan)泵所配電機功率將大幅提高(gao),設(she)備運行電費也隨之(zhi)增加的(de)問題。

由于活(huo)(huo)(huo)(huo)(huo)(huo)塞(sai)體上端(duan)(duan)的(de)(de)承壓(ya)(ya)(ya)面積(ji)比(bi)活(huo)(huo)(huo)(huo)(huo)(huo)塞(sai)體下(xia)(xia)端(duan)(duan)的(de)(de)承壓(ya)(ya)(ya)面積(ji)減少了一根活(huo)(huo)(huo)(huo)(huo)(huo)塞(sai)桿的(de)(de)面積(ji),因此(ci),密(mi)封(feng)油壓(ya)(ya)(ya)力(li)(li)按兩(liang)端(duan)(duan)承壓(ya)(ya)(ya)面積(ji)反比(bi)例(li)地增(zeng)加,從而保證密(mi)封(feng)條件。設計活(huo)(huo)(huo)(huo)(huo)(huo)塞(sai)兩(liang)端(duan)(duan)承壓(ya)(ya)(ya)面積(ji)之比(bi)時(shi),應根據(ju)所(suo)要求的(de)(de)密(mi)封(feng)腔與釜內的(de)(de)壓(ya)(ya)(ya)力(li)(li)差來(lai)計算(suan)。活(huo)(huo)(huo)(huo)(huo)(huo)塞(sai)桿上裝有彈(dan)簧(huang),調節(jie)彈(dan)簧(huang)的(de)(de)壓(ya)(ya)(ya)縮量,使(shi)彈(dan)簧(huang)力(li)(li)正好抵(di)消活(huo)(huo)(huo)(huo)(huo)(huo)塞(sai)上O形圈(quan)對缸壁的(de)(de)摩擦力(li)(li),以減少壓(ya)(ya)(ya)差計算(suan)值與實際之間(jian)的(de)(de)誤差。此(ci)外,活(huo)(huo)(huo)(huo)(huo)(huo)塞(sai)升(sheng)降還有指示平衡(heng)罐中液(ye)(ye)位(wei)的(de)(de)作用(yong)。當密(mi)封(feng)液(ye)(ye)漏泄需要補充(chong)時(shi),可用(yong)手動(dong)泵加注密(mi)封(feng)液(ye)(ye)。在使(shi)用(yong)時(shi)需注意(yi)活(huo)(huo)(huo)(huo)(huo)(huo)塞(sai)應經常處于平衡(heng)罐的(de)(de)下(xia)(xia)部位(wei)置(zhi),使(shi)活(huo)(huo)(huo)(huo)(huo)(huo)塞(sai)有向(xiang)上移動(dong)的(de)(de)余地。
