1 问题的提出多年来,风井风硐里风量、风压的测定,是测风员带着风表到风硐里测定,从风机房“U”型压差计上读取风硐中的负压。实践表明,该法存在以下不足:(1 )测量困难、误差大。由于风硐里风速、负压大,环境恶劣,测风员难以站稳,测定存在着严重的视觉误差、人工定时误差、表
1 raised the issue over the years, the wind hole Wind tunnel air volume, wind pressure determination is the wind vindicator with wind table to determine the wind hole, from the wind turbine room “U” type differential pressure gauge to read the wind tunnel Negative pressure. Practice shows that the law of the following deficiencies: (1) measurement difficulties, errors. Due to the wind tunnel, the wind speed, negative pressure, poor environment, the wind gusts can not stand firm, there is a serious visual error in the determination of artificial timing error, the table
