技術特色

磁浮軸承的力量與定轉子間隙成平方反比，為非線性的關係，因此必須限制轉子的可移動範圍。離心壓縮機試量產組裝重點需反覆確認磁浮軸承間隙。過去必須依靠磁浮軟體判斷，經常反覆拆卸調整耗費組裝時間。應用磁浮軸承間隙量測與調整技術，預測調整軸向間隙，可減少反覆調整組裝時間。轉軸徑向可移動間隙是由輔助軸承來限制，避免磁浮控制失效時壓縮機元件遭受撞擊。葉輪前後迷宮軸封與轉軸的間隙，略大於前項輔助軸承與轉軸間隙，加大迷宮軸封間隙，可使得組裝變得簡單，但會導致氣體洩漏量增加使壓縮機性能效率降低，且會增加軸向力造成控制上的不穩定。應用葉輪迷宮軸封組裝技術與治具，以及應用磁浮主軸總成徑向間隙巡跡量測檢驗工具，無需增加迷宮軸封間隙，可有效快速完成磁浮離心壓縮機組裝。
