Analysis of Working Status of High-pressure Centrifugal Fan in Centralized Pneumatic Feeding System of Cigarette Factory at Higher Altitude Areas
摘要
Abstract
The working status of high-pressure centrifugal fan in pneumatic system is varied at different altitudes. The characters of atmospheric pressure, temperature and air density at higher altitude and the effects of altitude on output air pressure and air volume, effective power and efficiency of high-pressure centrifugal fan were analyzed by taking cigarette factories in Yunnan and Hunan as examples, the same pneumatic systems at two different altitudes were tested. The results showed that the output air pressure of fan and output power of fan motor decreased with the ascent of altitude, while the output air volume of fan unchanged. Therefore, the rating of selected fan should be corrected according to local altitude, temperature and air density, and the entry status parameters of fan should be marked out to ensure the normal running of equipment.关键词
