Research and Application of Frequency Conversion and Consumption Reduction Technology for Coal Mining Machine
Aiming at the problems of low efficiency,high energy consumption,and high equipment maintenance costs in the traditional control method of coal mining machines in fully mechanized coal mining faces,this paper conducts research on the application of permanent magnet synchronous frequency conversion technology for coal mining machines and proposes a frequency conversion and consumption reduction technology scheme for coal mining machines.According to this plan,the transmission drive motor is replaced with a permanent magnet driven variable frequency motor,achieving soft start of the motor and reducing mechanical efficiency and energy consumption.On site applications have shown that variable frequency soft start can greatly improve the mechanical efficiency and transmission system efficiency of coal mining machines,reducing equipment energy consumption by 34.6%.This study can provide certain application references for future research on energy-saving of coal mine electromechanical equipment and intelligent remote frequency conversion control.
