G4-73通风机变频改造技术

G4-73 Fan Frequency Conversion Technology

铁北矿准备再投产新一采区,按目前的生产系统,1#风井的风机已不能满足要求,而且效率低,准备启用2#风井主扇风机,同时改变通风网路。提出对现有风井进行技术改造,并提出3个改造方案进行了选择计算比较,确定最佳方案。实际运行总的结果也是非常令人满意的,运行效率提高30%,具有推广价值。

Tiebei coal mine ready to put into production a new mining area, according to the current production system, the fan of No. 1 Air shaft cannot meet the requirements, and the efficiency is low,prepared to enable the No. 2 air shaft fan of the main fan, and alter ventilation network. It puts forward the technological transformation of existing air shaft, and puts forward three reconstruction schemes were calculated and compared, to determine the best solution. The actual running total results are also very satisfactory, raised 30% operating and it have the promotion value.
