摘要
在涡轮流量计的使用过程中,由于磨损、震动等因素,使流量不稳定,引起计量不准确。为了满足高性能涡轮流量计稳态及动态校准的需求,设计了采用活塞式计量缸的流量计校准装置。为验证系统的性能,提出建立了涡轮流量计数学模型,然后在基于AMESim平台建立的校准装置的仿真模型中,通过仿真验证了系统的性能和影响计量精度的主要参数。仿真结果表明,校准系统稳定可靠,能够达到预定的输出流量。同时,系统的稳态及动态性能满足要求,涡轮流量计模型符合系统建模准确度要求。仿真结果为校准装置设计提供了预先分析、验证与优化的参考。
To meet the requirements of high performance steady and dynamic calibration, a set of calibration de vice based on piston typed metering cylinder was established. To verify system performance, a mathematical model of turbine flowmeter was established and the system modeling and simulation were carried out using platform of AMESim. The results show that the calibration system is stable, reliable and able to achieve the desired output flow. Meanwhile, dynamic and steady state performances of the system can meet the requirements of calibration, and the turbine flowmeter model is suitable for system modeling accuracy. Simulation results can provide some reference to pre analysis, validation and optimization for the calibration device design.
