Take current controller's fan system

The utility model discloses a take current controller's fan system, including fan, blast gate, filter, the blast gate sets up between fan and filter, still is provided with current controller and electric actuator, and electric actuator set up before the blast gate, current controller passes through the aperture of electric actuator control blast gate. It makes fan, blast gate and current controller form a closed loop control system, through the method control fan electric current of the control system amount of wind, prevents that the fan from burning out the fan because of the overcurrent, on the basis of improving the current measurement precision, also can reach the effect of adjusting the amount of wind through control current simultaneously, plays the steady amount of wind and improvement control accuracy's effect. 本实用新型公开了种带电流控制器的风机系统，包括风机、风阀、过滤器，风阀设置于风机与过滤器之间，还设置有电流控制器和电动执行器，电动执行器设置在风阀之前，所述电流控制器通过电动执行器控制风阀的开度。其使得风机、风阀和电流控制器形成个闭环控制系统，通过控制系统风量的方法控制风机电流，防止风机因为过电流烧毁风机，同时在提高电流测量精度的基础上，也可以通过控制电流达到调节风量的作用，起到
