中文摘要 | 低壓鑄造機之壓力控制系統,是將氣壓伺服控制技術運用致鑄件之製造過程以期 得到較高品質之鑄件。在低壓鑄造機的系統中,氣體的洩漏,金屬液的慣性,金屬溶液的耗 損,爐內溫度的變化等因數均會影響爐內壓力的變化,在此對低壓鑄造機之壓力作動情況作 一概括的敘述以作為設計低壓鑄造機壓力控制器之基礎。 |
英文摘要 | The control system of LPDC applies the pnumetic servo control technique to the casting manufacturing precess to produce high quality casting. Yet there are several factors which influence the internal pressure of the holding furnace, such as gas leakage, molten metal inertia, melt consumption and temperature variation in the LPDC pressure system, Thus the introduction of the LPDC pressure system can be served as a basis to design a LPDC pressure controller. |
