|
|
Abstract This paper mainly introduces the structure and working principle of a piston type gas flow standard device, in order to reduce the influence of different factors, Traceability and transfer of convenient volume, the device need additional configuration of a system of grating displacement correction. Through repeated experiments, the main factors of impacting grating performance are flow, the grating installation, piston and piston cylinder block machining precision and lubricating condition, finally puts forward suggestions for the future, Providing reference to the piston type gas flow standard device for further improve.
