Application of Frequency Conversion Control Technology in Coal Mine Main Ventilator
Release time:
2018-08-23
The application of frequency conversion control technology in the main fan of coal mine is mainly reflected in the following aspects:
The energy-saving effect is remarkable: the frequency converter can adjust the motor output power according to the actual demand, effectively reduce the motor output power of the main fan, so as to achieve the purpose of saving electricity. And the larger the adjustment range of the main fan, the more obvious the power saving effect.
To achieve smooth stepless speed regulation: the electric control system uses PLC instead of the traditional analog control and electrical contact with the program, only control the rotor slip power, improve the reliability of the system, reduce equipment investment. Double closed loop regulation technology can realize smooth stepless speed regulation and hard mechanical characteristics, which is the best scheme for coal mine main fan speed regulation.
Improve control accuracy and response speed: The inverter can monitor the operating status of the main fan in real time, and quickly adjust the motor speed according to actual needs, so as to achieve precise control of air volume, wind pressure and other parameters.
Extend the service life of the equipment: the frequency converter can optimize the motor start-up and shutdown process, reduce the impact on the power grid and mechanical equipment, reduce the failure rate, and extend the service life of the equipment.
Easy to maintain and manage: frequency conversion control technology adopts digital control mode, which can monitor the running status of equipment in real time through intelligent instrument and upper computer software, which is convenient for maintenance and management.
In short, the application of frequency conversion control technology in the main ventilator of coal mines has significant advantages and benefits, which can improve the safety and reliability of the ventilation system, reduce energy consumption and maintenance costs, and improve the production efficiency and economic benefits of coal mines.
