一、导言预拱型爆破膜装置是目前石油化工设备上广泛应用的安全装置。为保证化工设备安全运行,一般要求将实际爆破压力限制在额定爆破压力的±5%以内。吴泽炜教授等已推导出较精确且简便的计算爆破压力的公式。不过该计算方法中所用的膜片机械性能等参数(如
I. INTRODUCTION Pre-arch blasting membrane device is a widely used safety device on petrochemical equipment. In order to ensure the safe operation of chemical equipment, the general requirements of the actual burst pressure is limited to ± 5% of the rated burst pressure. Professor Wu Zewei has deduced a more precise and simple formula to calculate the burst pressure. However, the calculation method used in the diaphragm mechanical properties and other parameters (such as
