拋丸機用鋼砂液力輸送試驗鋼板防腐除銹方案

LANMU:CHANPINWENDA YUEDU:1196

整個試驗裝置是由各個系統組成,各個系統之間相互影響,理想的試驗裝置是需要各個系統之間達到動態的平衡,即噴射泵單位時間內向拋丸機輸送的鋼砂量與拋丸機單位時間內消耗的拋丸量需要達到平衡,同時還需要觀察拋丸機在對應的拋丸量下帶鋼表層的氧化皮去除效果。

由于經濟和實際操作不方便等原因,在鋼砂液力輸運的試驗中,鑄造不同結構參數的噴射泵所需要的費用較大,而且在實際過程中,拆卸和安裝噴射泵非常不方便,所以在實際試驗過程中只能通過更換不同尺寸的噴嘴后,觀察供砂桶中鋼砂與水的混合物的體積變化情況,來驗證上一章節中數值仿真的結果。

1.采用自主設計研發的濕式拋丸試驗裝置,通過更換噴射泵中的噴嘴來驗證上一章:節得到的噴嘴到喉管距離對鋼砂吸入量的影響。
2.通過拋丸試驗,驗證了濕式拋丸工藝及裝置的可行性,利用電子顯微鏡對拋丸后的帶鋼表面進行觀察,驗證了濕式拋丸對帶鋼表面氧化皮有很好的去除效果。
