海北機械密封又叫端麵密封，在有關標準中是這樣解說的：youzhishaoyiduichuizhiyuxuanzhuanzhouxiandeduanmianzailiutiyalihebuchangjigoudanlidezuoyongyijifuzhumifengdepeihexiabaochitiehebingxiangduihuadongergouchengdefangzhiliutixieloudezhuangzhi。
海北機械密封自身壓力增壓係統結構包括出水口、固定法蘭、泵體、增壓裝置、電機轉子、吊環、防護罩、水泵、固定基座、底座、加固件、控製閥、緊固件，所述出水口與固定法蘭相連接，泵體與增壓裝置相連接，增壓裝置由進水口、水管、負壓室、平衡固定盤、緊jin固gu支zhi架jia組zu成cheng，進jin水shui口kou與yu水shui管guan相xiang連lian接jie，水shui管guan與yu負fu壓ya室shi相xiang連lian接jie，負fu壓ya室shi通tong過guo平ping衡heng固gu定ding盤pan保bao持chi平ping衡heng，緊jin固gu支zhi架jia與yu泵beng體ti固gu定ding連lian接jie，防fang護hu罩zhao與yu水shui泵beng相xiang連lian接jie，水shui泵beng與yu固gu定ding基ji座zuo相xiang連lian接jie，固gu定ding基ji座zuo與yu底di座zuo緊jin固gu連lian接jie，底di座zuo上shang設she有you加jia固gu件jian，緊jin固gu件jian與yu底di座zuo固gu定ding連lian接jie。帶dai有you平ping衡heng罐guan的de海北機械密封自身壓力增壓係統是一種壓力傳遞機構，用於雙端麵海北機械密封，yijiejuexianyoudexunhuanshuibengdebufenbunengkefuxitongdezuli，zaixunhuanbengliuliangbubiandeqingkuangxia，yidanxunhuanbengdeyangchengbiangao，zexunhuanbengsuopeidianjigonglvjiangdafutisheng，shebeiyunxingdianfeiyesuizhizengjiadewenti。
由於海北機械密封活塞體上端的承壓麵積比活塞體下端的承壓麵積減少了一根活塞杆的麵積，因此，海北機械密封油you壓ya力li按an兩liang端duan承cheng壓ya麵mian積ji反fan比bi例li地di增zeng加jia，從cong而er保bao證zheng密mi封feng條tiao件jian。設she計ji活huo塞sai兩liang端duan承cheng壓ya麵mian積ji之zhi比bi時shi，應ying根gen據ju所suo要yao求qiu的de密mi封feng腔qiang與yu釜fu內nei的de壓ya力li差cha來lai計ji算suan。活huo塞sai杆gan上shang裝zhuang有you彈dan簧huang，調tiao節jie彈dan簧huang的de壓ya縮suo量liang，使shi彈dan簧huang力li正zheng好hao抵di消xiao活huo塞sai上shangOxingquanduigangbidemocali，yijianshaoyachajisuanzhiyushijizhijiandewucha。ciwai，huosaishengjianghaiyouzhishipinghengguanzhongyeweidezuoyong。dangmifengyelouxiexuyaobuchongshi，keyongshoudongbengjiazhumifengye。zaishiyongshixuzhuyihuosaiyingjingchangchuyupinghengguandexiabuweizhi，shihuosaiyouxiangshangyidongdeyudi。
