礦井充填站現場

更新時間:2020-03-24 19:45點擊次數:
(1) 輸送管路的性能直接關系到礦山充填的效率和效果,其使用壽命受到顆粒特性、料漿濃度、流速、壓力、鉆孔偏斜率、充填倍線、施工質量等多種因素的影響,同時也與輸送管道的技術工藝性能密切相關,隨著采礦深度的不斷加大,輸送工況更加復雜,因此合理選擇充填輸送管道,是預防堵塞爆管、泄漏污染、鉆孔報廢等惡性事故的重要措施,直接關系到企業的安全生產和經濟效益。
(2) 雙金屬復合耐磨管結構合理、工藝先進,耐磨層采用了抗沖蝕磨損性能優良的KMTBCr28 高鉻合金,在熱鑄狀態下復合成形,使材料的耐磨性和韌性有機結合,抗沖擊能力和抗熱振性能顯著,整體機械性能大幅提高,使用安全可靠。實踐證明其使用壽命(累計充填量)達到了普通鋼管的10 倍乃至20 倍以上,技術性能優勢十分明顯,特別適用于礦山充填輸送惡劣的工況條件。
