我国《煤炭工业设计规范《第2-123条规定了载重量在20t以下的箕斗的休止时间,但对20t以上的箕斗休止时间未作具体规定.在设计中,一般仍采用1s/t.究其原因:首先国内大于20t箕斗还未做出标准设计,缺乏运行经验,其次即使同一箕斗,由于原煤粒度和湿度等性能不同,卸载速度有差别;再次,为提升能力留有大的富裕系数.最终导致大的绞车提升能力不能得到充分发挥.因此,对大型箕斗的休止时间如何选取比较合理,有讨论的必要.
China’s “Coal Industry Design Code,” Article 2-123 of the provisions of the deadweight below 20t skip, but not more than 20t skip duration not specified in the design, the general still use 1s / t . The reason: First, the domestic more than 20t skip has not yet made a standard design, the lack of operational experience, followed by the same skip, due to the different performance of the coal particle size and humidity, unloading speed difference; again, to enhance the ability to leave a large Of the rich coefficient, eventually leading to a large hoisting capacity can not be fully exerted.Therefore, how to choose the rest period of large skip is more reasonable, and it is necessary to discuss.
