摘要:
针对压力表检定时逐点压力检测的用压需求，设计了一种适用于0~6 MPa的自动气压发生器，为压力表的计量检定过程提供自动化的压力供给，研究该加压装置结构参数对造压规律的影响。利用AMESim建立装置仿真模型，以气体压力加载精度及压力响应速度作为两个重要指标，对增压缸内径、行程、初始供气压力等因素进行变参分析，研究相关参数对气压发生装置压力波动程度和响应速度的影响，最后对6 MPa满量程压力表检定时的供压过程进行了压力仿真与样机试验。结果表明：仿真曲线基本符合样机试验结果，在检定点处的仿真压力与试验压力误差在0.05%以内，符合检规最高准确度等级需求。相关研究可为压力表计量检定领域内气体介质压力发生装置的设计及气压控制方法提供参考。
Abstract:
According to the pressure requirement of point-by-point pressure detection during the verification of pressure gauge, an automatic pressure generator suitable for 0-6MPa is designed to provide automatic pressure supply for the measurement verification process of pressure gauge, and the influence of the structural parameters of the pressure device on the pressure building rule is studied. The simulation model of the device is established by AMESim. With the gas pressure loading precision and pressure response speed as two important indexes, variable parameter analysis is carried out on the pressurizing cylinder inner diameter, stroke, initial gas supply pressure and other factors, and the influence of related parameters on the pressure fluctuation degree and response speed of the pneumatic generator is studied. Finally, the pressure simulation and prototype test of the pressure supply process of the 6 MPa full range pressure gauge are carried out. The results show that the simulation curve basically accords with the test results of the prototype, and the error between the simulation pressure and the test pressure at the detection point is within 0.05%, which meets the requirement of the highest accuracy level of the gauge. The relevant research can provide reference for the design of gas medium pressure generator and pressure control method in the field of pressure gauge measurement verification.
