Mine Main Ventilator Control System

The main air volume of mine refers to the air volume of main inlet and return air shaft. The main ventilator`s working condition is automatically adjusted by using frequency control technology, realizing intelligent adjustment and control for the main air volume and air pressure of mine. In terms of concrete implementation, to meet the air volume required for underground operation, the frequency control system in main fan power supply module is used to control the main fan frequency conversion operation, and automatically adjust the speed of the ventilator on a large scale to make it operate under the optimum condition. When need to reduce the air volume, the synchronous speed can be changed by reducing the stator supply frequency of the motor, which can realize the main fan speed decrease; Conversely, when need to increase the air volume, it can be realized by increasing the motor stator supply frequency. Using the frequency converter to drive the operation of the main ventilator not only can realize the soft start of the ventilator and the stepless smooth speed regulation but also can greatly reduce the energy consumption of the fan and save energy. Huafei company could provide complete Ventilator Control include Ventilator Control Cabinet, Medium Voltage VFD for ventilator.
