摘要：超压泄放装置是保证承压设备结构安全的重要部件,保障其在设定压力下具备准确的动作特性至关重要,但目前对超压泄放装置在高升压速率载荷下的研究仍不充分。本文开发高升压速率载荷试验平台,分析平台实现高升压速率载荷的影响因素。基于试验验证,本文开发的平台可有效实现无极调节升压速率,且具有良好的试验重复性能,输出载荷的升压速率误差在±1%以内。所研制的平台解决了高升压速率载荷试验安全性、载荷可控性以及重复性的难题,为超压泄放装置性能研究提供基础。
The overpressure relief device is an important part to ensure the structural safety of pressure equipment.Existing research on the pressure relief device under high pressure rise rate load was still insufficient.It is very important to ensure that it has accurate action characteristics at the set pressure.If the overpressure relief device cannot act correctly,the structural integrity of the pressure vessel is at risk of damage.In this paper,an experimental platform of high pressure rise rate load is developed.And the influencing factors of high pressure rise rate load are analyzed.Through the theoretical analysis,the factors affecting the pressure rise rate load include the opening rate and opening angle of the quick-opening module,the initial air pressure and the air volume.The experimenter can achieve different pressure rise rate loads by adjusting the heavy objects weight,the heavy objects free fall initial height,the pressurization module output air pressure,and the height of the internal limiter of the energy storage module.Based on experimental validation,the platform can effectively generate high pressure rise rate loads with infinitely adjustable pressure rise rates.The output load pressure rise rate error is within±1%,which proves that the high pressure rise rate load generated by the experimental platform has reliable repeatability.The developed experimental platform solves the problems of safety,load controllability and repeatability of high pressure rise rate load test,and it provides a basis for the performance research of overpressure relief device.
