100L/min浮游菌采样器流量校准工况

Flow rate calibration condition for 100 L/min airborne microbe samplers

通过在采样工况条件下获得100 L/min浮游菌采样器的工况阻力实验,设计了合理的100 L/min浮游菌采样器的流量校准工况条件和模拟工况装置,使浮游菌采样器在使用模拟工况装置状态下获得的校准流量更接近于实际采样状态下的流量,为浮游菌采样器的采样流量校准提供了一定的实验依据。

This paper obtained the working condition resistance of 100L/min airborne microbe samplers under the sampling condition byexperiments, and designed a reasonable flow rate calibration condition anda working condition simulator for 100 L/min airborne microbe samplers.By using the simulator during calibration the calibrated flow rate of theairborne microbe sampler approached better the real flow rate under actualsampling condition. This paper provided some experimental basis forcalibrating the sampling flow rate of airborne microbe sampler.
