喷射真空泵在膨化硝铵炸药生产中的应用研究

Application of Ejector Vacuum Pump in the Manufacture of Industrial Expanded Ammonium Nitrate explosive

阐述了喷射真空泵的基本原理及特点,介绍了喷射真空泵结构及在膨化硝铵炸药生产中的研究应用发展状况。针对传统的射流真空泵和新研制的喷射真空泵性能进行对比分析,提出了改变传统设计思路,提高喷射泵效率的有效途径。结果表明,同射流泵相比,喷射真空泵抽气速率从462m3/h升至653m3/h,噪音从96dB降至88dB,能耗降低40.5%。

The basic principal and characteristics of ejector vacuum pump were summarized in this paper with a fo- cus on its structure and the research development on its application in the fabrication of the expanded ammonium nitrate ex- plosive. The contrast property analysis between the traditional jet vacuum pump and the newly developed ejector vacuum pump leads to the proposal on the effective ways in improving the ejector vacuum pump＇s efficiency. The experimental re- sults show a lashing velocity increase of 191 m3/h, a noise level decrease of 10dB, and an energy consumption reduction of 40.5% in the performance of ejector vacuum pump in comparison to its traditional counterpart.
