摘要

为了保证泵试验台的精度和测量的稳定性,需要配备高精度流量计和标定系统。提出了一种原位标定的体积-重量法,实现了双向标定。可在泵的试验台上进行双向校准。根据设计目标,对泵、称重箱、水池、换向器和标准量筒进行了计算和选择。基于测量不确定度法,系统的不确定度包括标准量筒、计算器、换向器和体积法校准传感器的不确定度。给出了这些不确定度的计算公式。系统的总扩展不确定度为0.136%,流量稳定性为0.0212%。计算和压力脉动实验结果表明,换频装置与不变性池相结合可以保持试验的压力稳定性。体积-重量法是重量法和体积法相结合的校准方法,既保证了校准的准确性,又降低了校准成本。它可以应用于类似的测试平台。ASME版权所有©2011

Research and Practice on the In-Situ Calibration System for Flowrate of Pump-Test-Rig
In order to assure the accuracy of pump test rig and stability of measurement, it would be equipped with flow meter of high precision and calibration system. A volume-weight method for in-situ calibration is brought out to achieve bidirectional calibration. The two way calibration can be done on the pump test rig. According to the design objective, the pump, weight tank, pool, commutator and standard measuring cylinder were calculated and selected. Based on measurement uncertainty method, the system uncertainty consisted of uncertainty of standard measuring cylinder, calculagraph, commutator and calibration sensor of volume method. The calculation formulas of these uncertainties are presented. The total expanded uncertainty of system is 0.136% and the stability of flowrate is 0.0212%. Results from calculation and pressure pulse experiment indicate that the combination of the convert-frequency facility with invariableness’ pool can maintain the pressure stability of test. The volume-weight calibration method, which combined with the weight method and volume method, can assure the accuracy and also reduce the expensive. It could be applied in similar test rigs.Copyright © 2011 by ASME
