固体制剂车间间歇性局部排风设备对压差影响的解决方法

Solution to the influence of the intermittent local ventilation on the pressure difference between rooms in a pharmaceutical workshop

在固体制剂车间净化空调系统的改造中,为维持各房间稳定的压差,对间歇性开停的局部排风设备采用相应的电动阀,通过相应电动阀实现间歇性开停回、排风变化条件下气流压差及流向的稳定性,并达到了GMP认证的要求。

Because of the intermittent local ventilation, it is difficult to maintain the pressure difference in the air clearing system between the rooms in a pharmaceutical workshop. In this paper, two electrical valves were used to stabilize the air flow direction and pressure difference between every two rooms in the workshop, and the results met the requirements of GMP.
