Description
Technical field
The present invention relates to a kind of ribbon conveyer efficiency on-line monitoring method and on-line monitoring system.
Background technology
Ribbon conveyer is contemporary Bulk material and the most efficient equipment of handling, be widely used in coal, Ore, cement and
The bulk cargo terminals such as grain.
According to statistics, more than 5,000,000, the existing ribbon conveyer of China, wherein for bulk cargo terminals more than 30,000.At present
The performance requirement of ribbon conveyer is often confined to the aspects such as distance, speed, freight volume, power, pays the utmost attention to during apolegamy motor
Equipment maximum load, overload capacity and reliability, project plan comparison are guarded, and selected device has larger allowance.Therefore, belt conveying
The raising of engine efficiency, it is very great to bulk cargo terminals energy-saving and emission-reduction meaning.
As belt conveyor system develops to long range, high belt speed, large conveying quantity, its energy conservation potential is huge.For this purpose, traffic
Portion《" 12 " water transport energy-saving and emission-reduction totally advance embodiment》([2011] No. 474 files) is proposed to want emphasis research and development and is promoted
Ribbon conveyer saving-energy operation control technology." frequency control belt conveyor system efficiency test and amount of energy saving computational methods " state
