【摘要】 介绍了对旋式通风机的性能测试方法。并对其在相同流量的条件下,两级叶轮同时工作时的全压与每一级叶轮单独工作时的全压之和进行了分析、比较,从而为安全使用对旋式通风机提供了理论依据。更多还原

【Abstract】 The performance test methods for counterrotating fan is introduced.Under the condition of the same capacity,total pressure of two-stage impellers simultaneous working and the sum of total pressure that single stage impeller run alone are analyzed and compared,so it provides theory basis for safe running of counter-rotating fan.更多还原
