旋风机 meaning in English

cyclone cluster

Development of step delay auto - switching device of high - power contra - rotary fan
大功率对旋风机分级延期自动切换研制
The problem of noise of the fan is studied with the non - linear theory , and pressure pulsation of axial flow fan ' s inside flow was measured by dynamic pressure sensor , the gas - structure coupled noise of contra - rotating axial flow fan was studied through a new perspective
摘要用非线性动力学的理论对风机噪声问题进行了分析，同时运用实验手段测量了轴流风机流场内部流动的压力脉动，从全新的角度研究了对旋风机的气固耦合噪声。
