一、“谷物联合收割机径向进气风扇研究”课题是机械工业部1983年下达我院的,由农机研究室朱永宁副教授负责。课题组通过对径向进气风扇的理论分析和大量的实验研究,掌握了这种风扇的性能规律和基本的结构参数;获得了单调下降性能曲线的径向进气风扇模型和设计方法;应用机械相似设计方法设计和制造了适合联合收割机喂入量为5～6公斤/秒、含杂率30%物料的径向进气风扇,在清选试验台上与传统的离心风扇作了对比试验,取得了良好的清选效果。最近,由河南省教委主持了鉴定。鉴定委员会认为:该项研究完成了既定任务,在单风道径向进气风扇研究方面,达到国内先进水平;在径向进气风扇与联合收割机清
First, the “grain combine harvester radial intake fan research” issue is the Ministry of Machinery Industry issued to our hospital in 1983, by the Agricultural Research Laboratory Zhu Yongning associate professor. The research team obtained the performance of the fan and the basic structural parameters through the theoretical analysis of the radial intake fan and a large number of experimental studies; radial intake fan model and design method of monotone descent performance curve; application Mechanical Design Approach A radial air intake fan designed for a combined harvester feed of 5 to 6 kg / s with 30% solids loading was designed and manufactured to compare with conventional centrifugal fans on a clean bench Test, made a good cleaning effect. Recently, the Henan Provincial Board of Education presided over the identification. Accreditation Committee believes that: The study completed the established tasks in the single duct radial intake fan research, to reach the domestic advanced level; radial intake fan and combine harvester
