Gas boiler exhaust fan speed control device

摘要

This research is about the exhaust fan of the gas boiler. More specifically, in order to speed up the rise of the initial rotation of the exhaust fan when the boiler is in initial operation, the control device for the rotation of the exhaust fan of the gas boiler is designed.;As the temperature of the inner coil of the motor driven by the exhaust fan increases, the automatic closing device is connected with the coil in parallel. At the beginning of the start-up, with the transfer of the power supply, the control rotates at the highest speed, As the temperature increases, the most is cancelled and a normal coil is formed.
