隨州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,用于雙端面隨州機械密封,以(yi)解(jie)決現有的(de)(de)(de)循(xun)環(huan)水泵(beng)(beng)的(de)(de)(de)部分揚程不能克服系統的(de)(de)(de)阻(zu)力,在循(xun)環(huan)泵(beng)(beng)流(liu)量不變的(de)(de)(de)情況下,一旦(dan)循(xun)環(huan)泵(beng)(beng)的(de)(de)(de)揚程提(ti)高(gao),則(ze)循(xun)環(huan)泵(beng)(beng)所配電(dian)機功率將大幅提(ti)高(gao),設備運行電(dian)費(fei)也隨之增加(jia)的(de)(de)(de)問題。
