The Role of Safety and Energy Saving in Local Ventilation by Frequency Variable Speed Regulator
TONG Qiang
1995, 21(2): 8-11.
Abstract:
In coal mine local ventilations, 660V flameproof frequency variable speed regulator, matched with intelligent methane locking device of air door and power, could improve mine safety, energy saving and mining productivity. The author briefly introduced the current status of frequency variable speed regulator development, and the comparisons between the energy saving effects by various air volume control, and its role of energy saving and some suggestions for future use.
