摘要
风量是反映煤矿主要通风机性能优劣的主要参数之一,也是煤矿选择主要通风机的主要依据。风量测定是煤矿主要通风机安全技术性能测定的重要环节之一,能否准确测定风量将直接影响到煤矿主要通风机安全技术性能测定的成败。本文简要分析了目前广泛采用风量测定方法的局限性,介绍了静压差法测定风量的原理及验证效果,提出了采用静压差法测定风量时应注意的一些事项。
The flowrate is one of the main parameters that reflect the performance of main fan, and it is also the primary basis of main fan selection in coal mine. The flowrate measurement is one of the most important liks to the examination on safety technical performance of main fan in coal mine. Whether the flowrate can be accurately measures will directly influence the success of the examination on satety technical performance of main fan in coal mine. The limitation of flowrate measurement methods that were widely applied at present was briefly analyzed. The mechanism and validation results of static differential pressure method for measurement of flowrate were introduced, and some important notes during its application were proposed.
