山东里能里彦矿业有限公司设计年产60万 t,2007年产量达到70万 t,主通风机为 G4-72-11型离心式,配250 kW 同步电动机。随-400水平的开采,东西翼延伸,需风量不断加大,目前风量为4700m~3/s,预计最大风量为8000m~3/s,主通风机的通风能力已经成为生产瓶颈。根据风量要求,需要对通风系统进行重新设计。
Shandong Li Nailiyan Mining Co., Ltd. with an annual output of 600,000 t design, production reached 700,000 t in 2007, the main fan for the G4-72-11 centrifugal, with 250 kW synchronous motor. With the exploitation of -400 level, the extension of the east-west wing requires a continuous increase of air volume. At present, the air volume is 4700m 3 / s and the maximum air volume is expected to be 8000m 3 / s. The ventilation capacity of the main ventilator has become the production bottleneck. Depending on the air volume requirements, the ventilation system needs to be redesigned.
