    近期,陜鋼龍鋼公司軋鋼廠對軋線供水泵進行全面升級改造,從細微處著手,創造大效益。

    該廠原高線濁環水泵在高負荷運轉下故障頻發,影響生產,不僅維修費時費力,能耗也一直居高不下。該單位技術人員多次考察,對水泵的綜合節電率數據進行詳細、認真地采集和計量,并對所采集的數據與系統最佳工況下的數據進行比對、計算和分析,算出具體的節能空間,并通過三方面改造實現節能降耗的目標。

    一是在水泵葉輪、泵筒表面涂納米耐磨層,并添加穩流裝置,減少進水阻力,降低水流對泵的沖擊力,大大延長了水泵的使用壽命;二是在軸套上添加轉子抗氣蝕裝置,減少泵體脆化、裂隙、損壞、葉輪破裂等氣蝕危害,使維修頻次和誤機風險有效降低,節省了人力和財力;三是調小各機械配合間隙,以提高水泵效率。

    目前,高線濁環水泵已改造完畢,試運行效果良好,水泵的運行電流從以前的580安降至480安,每小時可節電約55千瓦時,每臺水泵年綜合降耗效益可達45萬元。據悉,該單位將繼續對其余軋線水泵進行改造,以進一步降低成本,提高效益。
