把两横流风机串联运行时风机之间的气流特性与单风机性能相比较,发现了一些对实践有指导意义的规律:弱排强吸和强吸弱排组合在大流量时,对于系统性能提升很小,不提倡使用;在小流量时,节流器两侧压差增加,取得了较为明显的增压效果,同时流量增加显著;横流风机作为增流效果优于增压效果;当两风机吸排能力相当时,横流风机串联利于增加流量,对增压不显著。
Comparing the airflow characteristics of single-fan with the performance of single-fan when the two cross-flow fans are connected in series, we find some rules that have guiding significance in practice: when the combination of weak-row strong suction and strong suction weak-row is at high flow rate, Small, do not advocate the use of small flow, the throttle on both sides of the pressure increase, and achieved significant pressure boosting effect, while traffic increased significantly; cross-flow fan as a boost effect is better than the supercharger effect; when the two fans Absorption capacity is comparable, the cross-flow fan is conducive to increasing flow, the boost is not significant.
