变频调速技术在沥青搅拌设备中的应用设计

Application and design of frequency adjusting speed technology in asphalt mixing equipment

变频调速已被公认是最理想、最有发展前途的调速方式之一。采用通用变频器构成变频调速传动系统的主要目的,一是为了满足提高生产率、改善产品质量及改善生活环境等要求;二是为了节约能源、降低生产成本。正确使用变频器对于传动控制系统的正常运行非常关键,首先要明确使用变频器的目的,按照生产机械的类型、调速范围、速度响应和控制精度、启动转矩等要求,

Frequency conversion start-up difficult at the start of induced draft fan in asphalt mixing equipment,so the correct design is very important.The use of high frequency start and then converted to low frequency operation of the design can make it play its function.From the drawing design,frequency converter parameter setting,programming design have to match each other and perfect,otherwise can not reach the expected results.
