在铸造生产中,如何积极推广应用冲天炉节电小风机,是当前节能的重要课题,应引起我们足够的重视。 以前由于没有冲天炉专用风机,大部分选用罗茨风机和8—18—101离心风机。我厂铸造车间一座3吨/时热风冲天炉,原设计选用8—18—101离心风机,转速2900转/分,风压1465毫米水柱,风量170米~3/分,电动机为75千瓦。电力消耗较大。 HTD50—11型冲天炉节电风机系1976年由华中工学院等单位设计,湖北应山县鼓风机厂生产的3吨/时冲天炉专用风机。其风量50米~3/分,风压1300毫米水柱,配用JO_2—62—17,17千瓦电动机。该
In casting production, how to actively promote the use of cupola energy-saving small fan, is an important issue of energy conservation, should cause us enough attention. In the past there was no cupola dedicated fan, most of the selection of Roots blower and 8-18-101 centrifugal fan. I plant a foundry workshop 3 tons / hour hot cupola, the original design selection of centrifugal fans 8-18-101, speed 2900 rev / min, wind pressure 1465 mm water column, the air volume of 170 m ~ 3 / min, the motor is 75 kilowatts. Power consumption is larger. HTD50-11-type cupola energy-saving fans in 1976 by the Central China Institute of Technology and other units designed, Hubei Yingshan Blower Factory production of 3 tons / hour cupola dedicated fan. The air volume of 50 m ~ 3 / min, wind pressure 1300 mm water column, equipped with JO_2-62-17,17 kW motor. This
