池州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):99154 來(lai)源:

  池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,用于雙端面池州機械密封,以解決(jue)現(xian)有的(de)循環(huan)水泵(beng)(beng)(beng)的(de)部分揚程不能克服系統的(de)阻(zu)力,在循環(huan)泵(beng)(beng)(beng)流量不變的(de)情況(kuang)下,一旦循環(huan)泵(beng)(beng)(beng)的(de)揚程提高,則循環(huan)泵(beng)(beng)(beng)所配電機功率將大(da)幅提高,設(she)備運行電費(fei)也隨之(zhi)增(zeng)加的(de)問(wen)題(ti)。

  由于(yu)活(huo)塞(sai)體(ti)(ti)上(shang)(shang)端(duan)(duan)的(de)承壓(ya)(ya)面積比(bi)活(huo)塞(sai)體(ti)(ti)下端(duan)(duan)的(de)承壓(ya)(ya)面積減少了一根活(huo)塞(sai)桿的(de)面積,因此,密(mi)封(feng)油壓(ya)(ya)力按(an)兩端(duan)(duan)承壓(ya)(ya)面積反比(bi)例地增加,從而(er)保證密(mi)封(feng)條件。設(she)計(ji)活(huo)塞(sai)兩端(duan)(duan)承壓(ya)(ya)面積之比(bi)時(shi)(shi),應根據所要(yao)求(qiu)的(de)密(mi)封(feng)腔與(yu)釜內的(de)壓(ya)(ya)力差來計(ji)算(suan)。活(huo)塞(sai)桿上(shang)(shang)裝(zhuang)有彈簧(huang),調節彈簧(huang)的(de)壓(ya)(ya)縮量(liang),使(shi)彈簧(huang)力正(zheng)好抵消活(huo)塞(sai)上(shang)(shang)O形圈對缸壁的(de)摩擦力,以減少壓(ya)(ya)差計(ji)算(suan)值與(yu)實際之間的(de)誤差。此外,活(huo)塞(sai)升降還(huan)有指示平衡(heng)罐(guan)中液(ye)位的(de)作用。當(dang)密(mi)封(feng)液(ye)漏(lou)泄(xie)需要(yao)補充時(shi)(shi),可用手(shou)動泵加注密(mi)封(feng)液(ye)。在(zai)使(shi)用時(shi)(shi)需注意(yi)活(huo)塞(sai)應經常處于(yu)平衡(heng)罐(guan)的(de)下部位置(zhi),使(shi)活(huo)塞(sai)有向上(shang)(shang)移動的(de)余地。
