近年来,我矿贮矿仓机械漏斗闸门由风动的改为电动、液压和自动的三种,其中以电动的应用较多。这不仅在技术上有了很大的进展,而且在节约能源方面取得了较好的成绩。现将风动和电动闸门的耗电量作如下比较。我矿向阳坑每日出矿岩1300车,采用风动漏斗闸门,需开动20米~3空压机一台,正常负荷电流I=22～23安,电压E=3300伏,每日开动空压机时间t=18小时,功率因数cosφ=0.85,则每日耗电量:K_(WH)=1.732IEtcosφ/1000=1924(度/日)
In recent years, I mine storage silo mechanical funnel gate by the wind changed to electric, hydraulic and automatic three, including electric applications more. This not only made great progress in technology, but also achieved good results in energy conservation. Now the wind and electric gate power consumption for the following comparison. Mine mine to Xiangyan daily rock 1300 cars, the use of wind funnel gate, need to start 20 meters to 3 air compressors, the normal load current I = 22 ~ 23 amps, voltage E = 3300 volts, the daily open empty Press time t = 18 hours, the power factor cosφ = 0.85, the daily power consumption: K_ (WH) = 1.732IEtcosφ / 1000 = 1924 (degrees / day)
