摘　　要：针对活塞式气体流量标准装置活塞缸筒尺寸受限、流量范围较小的问题,设计了一种往复式双柱塞气体流量标准装置,基于该装置探索了单缸、双缸并联以及双缸串联等不同模式的运行规律。采用0.06 m^(3)/h名义流量喷嘴进行了检定实验,结果表明,装置在不同运行模式时的重复率均小于0.02%,其中单缸和双缸并联模式下检测误差不超过0.02%,双缸串联模式下不超过0.05%。To solve the problems of restricted dimension of cylinder and limited flow range of the plunger gas flow standard devices,a reciprocating double-plunger gas flow standard device was developed,operating modes including single-cylinder,parallel double-cylinder and tandem double-cylinder modes were explored.For different operating modes,the repeatability and accuracy of the device were verified by the calibration experiment of a sonic nozzle with the nominal flow rate of 0.06 m^(3)/h.Results revealed that the repetitive rate of the device was less than 0.02%at different modes,the errors of the device at single-cylinder and parallel double-cylinder modes were less than 0.02%,while the error of the device at tandem double-cylinder mode was less than 0.05%.
