通风参数测量仪表的实验校准与应用

Experimental Adjusting and Practicing of the Ventilation Parameter Measuring Instruments

通风参数测量仪表的校准是煤矿通风安全仪器仪表使用与管理的一项重要工作。本文通过气压检定箱实现了精密气压计的校准,通过闭式环形风硐实现了风表的校准,并应用于实际矿井通风阻力测定提高了测量精度。实践证明,通风参数测量仪表的校准能够提高日常通风测量及通风阻力测定数据的准确性,更好地满足了安全生产的需要。

The adjustment of the ventilation parameter measuring instruments is an important task for the using and managing of the mine ventilation safety instruments and meters. In this paper, the precision barometer is adjusted by the altichamber, the wind meter is adjusted by the closed annular wind chamber. And it was applied to mensurate the mine resistance to improve the accuracy of measurement. In practice,the adjustment of the ventilation parameter measuring instruments can enhancing the accuracy of data of the airflow measurement and the mine resistance, and fulfilling the requirement of safety in production better.
