rotary fan

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

This wet cyclone dust collector integrates dust removal by rotary atomizing and dust removal by cyclone dewatering into a whole and mainly consists of disc-type atomizer, guide device of air flow, dewatering device, fan and circulating water treatment system.

该湿式旋流除尘器集旋转雾化除尘和旋流脱水除尘于一体，主要由转盘式雾化器、风流导向装置、脱水器、风机和循环水处理系统组成。

either through the automatic frequency control system to control the running state of the fan, this system can prevent the occurrence of the surge of the counter rotary fan at any time, to avoid accidents caused by the surge of the counter rotary fan.

既可以通过自动变频调速系统控制风机的运行状态，又可以随时防止对旋风机喘振的发生，避免对旋风机因喘振而造成事故。

automatic frequency control anti-surge system circumvents the limitations of the method of ordinary surge and provides a new approach to solve the surge of the counter rotary fan.

自动变频调速防喘方法规避了普通防喘方法的局限性，为解决对旋风机喘振提供了新的方法。
