摘要: This paper describes the system architecture of a centrifugal backward curved fan, discuss experiences designed a fan. Using the initial design conditions, given static pressure, flow rate and rotating speed, you can calculate the size of the impeller and calculate airflow angle by one-dimensional model. From the example of this paper, vane inlet angle is 27 degrees, and the exit angle is 30 degrees, while the inlet airflow angle is 32.6 degrees, and the exit flow angle of 18.17 degrees by calculations. The main purpose of this paper to calculate the centrifugal fan of the one-dimensional model and design process. Centrifugal fan design process, including blade size, weight and stress of the impeller, bearing life and blower test the actual performance computing. Calculate specific rate from the initial design conditions, and select the fan type. Specific rate calculate blade size. Blade thickness is determined by the stress. Weight is calculated by the geometrical relationship. Bearing life is determined by the force of the impeller, shaft and the motor. Finally, finishing the centrifugal fan design. Fan performance test by the inner duct of the measured data, calculating and get the final result.
本文介紹離心後傾式送風機的系統架構,討論經驗方法設計一台送風機,利用初始設計的條件,給予靜壓、流量與轉速,即可算出葉輪的尺寸大小,並由一維模式計算氣流角度,由實例葉片入口角度為27度,出口角度為30度,而入口氣流角度為32.6度,出口氣流角度為18.17度。 本文主要目的計算離心式送風機的一程,離維模式與設計過心式送風機的設計過程,包含葉片尺寸、葉輪重量和應力、軸承壽命和實際送風機測試性能計算。由初始設計條件,計算比速率選擇風機型式,算出葉片尺寸大小,葉片厚度由應力來決定,利用幾何關係計算重量,軸承壽命由葉輪重、軸重和馬達的力來決定,最後完成離心式送風機的設計。送風機的性能測試由風管內所量測的數據,經過計算轉換得到最後的結果。
