工業園區什么是自身壓力增壓系統,與機械密封有什么關聯

發布時間:2021-12-17 11:55:58 人氣(qi):98235 來(lai)源:

  工業園區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,用于雙端面工業園區機械密封,以解決現有(you)的(de)循環(huan)水泵的(de)部(bu)分揚(yang)程不能克(ke)服(fu)系統的(de)阻力,在循環(huan)泵流量(liang)不變(bian)的(de)情況下,一旦(dan)循環(huan)泵的(de)揚(yang)程提高,則循環(huan)泵所配電(dian)機功率將大幅提高,設(she)備運行電(dian)費也隨之增加(jia)的(de)問題。
