摘要/Abstract

摘要： 针对移动式消防排烟风机普遍采用正压送风排烟模式，现有管内风量测试方法不能客观反映其无管道送风特性的问题，聚焦新型高效能大风量移动式消防排烟风机的送风特性及影响因素，建立了适用于无风道条件的风量测试方法。文章基于4台新型高效能大风量移动式消防排烟风机，共设计5种典型工况，完成风速与风量实测。测试结果表明，风速自轴心向外呈火山状衰减分布，风量则在某一特定圆环半径处达到最大值，二者分布规律不一致。在送风特性影响因素方面，风机功率对风量输出的影响最显著，其次为叶轮直径，而叶片数量与测试距离的影响相对较小。

Abstract: In view of the problem that mobile fire smoke exhaust fans generally adopt the positive pressure air supply and smoke exhaust mode, and the existing in-duct air volume testing methods cannot objectively reflect their ductless air supply characteristics, this paper focuses on the air supply characteristics and influencing factors of new high-efficiency and large-air-volume mobile fire smoke exhaust fans, and establishes an air volume testing method suitable for ductless conditions. Based on 4 new high-efficiency and large-air-volume mobile fire smoke exhaust fans, the paper designs 5 typical working conditions and completes the actual measurement of wind speed and air volume. The test results show that the wind speed attenuates outward from the axis in a volcano-like distribution, while the air volume reaches the maximum at a specific annular radius, and the distribution laws of the two are inconsistent. In terms of the influencing factors of air supply characteristics, the fan power has the most significant impact on air volume output, followed by the impeller diameter, while the number of blades and test distance have relatively smaller impacts.
