空气湿度对矿用低速风洞的风速表检定结果影响

分析矿用低速风洞的工作原理，研究目前所使用的检定规程JJG（煤炭）01―96《矿用风速表》，发现湿度的变化影响空气密度的变化，而空气密度的改变直接影响风速表的检定结果。忽略了湿度对空气密度的影响，会影响风速表检定结果的准确性。

This paper first introduces the current China＇s mining anemometer verification the basic situation, detailed analysis of the working principle of the mine low-speed wind tunnel. Based on the principle of this kind of work, we ware carefully studied mining anemometer VRof, The currently used VRof is JJG （coal） 01-96 《mining anemometer》 VRof, this statute ignored the impact of humidity on the verification results. In this paper, the effects of humidity study. The analysis found that changes in humidity will affect the changes in air density, and the air density changes directly affect the verification results of the anemometer. Ignoring the influence of the humidity of the air density will affect the accuracy of the anemometer verification results.
