錫林郭勒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，用于雙端面錫林郭勒機械密封，以解決(jue)現有的循(xun)環(huan)水(shui)泵的部分揚程(cheng)不能克服(fu)系統的阻(zu)力，在循(xun)環(huan)泵流量不變的情況下(xia)，一旦(dan)循(xun)環(huan)泵的揚程(cheng)提高，則循(xun)環(huan)泵所配(pei)電(dian)機功率將大幅提高，設備運行(xing)電(dian)費(fei)也隨之增加的問題。

　　由于活塞(sai)(sai)(sai)體(ti)(ti)上端(duan)的(de)承壓(ya)(ya)(ya)面積比(bi)(bi)活塞(sai)(sai)(sai)體(ti)(ti)下端(duan)的(de)承壓(ya)(ya)(ya)面積減少(shao)了一(yi)根活塞(sai)(sai)(sai)桿(gan)的(de)面積，因(yin)此，密(mi)(mi)封(feng)油壓(ya)(ya)(ya)力(li)(li)按兩端(duan)承壓(ya)(ya)(ya)面積反比(bi)(bi)例地增加，從而保證密(mi)(mi)封(feng)條件。設計活塞(sai)(sai)(sai)兩端(duan)承壓(ya)(ya)(ya)面積之比(bi)(bi)時(shi)，應根據所要求的(de)密(mi)(mi)封(feng)腔與釜(fu)內的(de)壓(ya)(ya)(ya)力(li)(li)差來(lai)計算。活塞(sai)(sai)(sai)桿(gan)上裝有彈簧(huang)，調節彈簧(huang)的(de)壓(ya)(ya)(ya)縮量(liang)，使彈簧(huang)力(li)(li)正好(hao)抵消活塞(sai)(sai)(sai)上O形圈對缸壁(bi)的(de)摩擦力(li)(li)，以(yi)減少(shao)壓(ya)(ya)(ya)差計算值與實際之間的(de)誤差。此外，活塞(sai)(sai)(sai)升降(jiang)還有指(zhi)示平(ping)(ping)衡罐(guan)(guan)中液位(wei)的(de)作用(yong)。當密(mi)(mi)封(feng)液漏泄需要補充時(shi)，可(ke)用(yong)手動(dong)泵加注密(mi)(mi)封(feng)液。在使用(yong)時(shi)需注意活塞(sai)(sai)(sai)應經常處于平(ping)(ping)衡罐(guan)(guan)的(de)下部位(wei)置，使活塞(sai)(sai)(sai)有向上移動(dong)的(de)余地。
