武漢鑫文豐機(jī)械有限公司是一家專業(yè)生產(chǎn)礦山機(jī)械設(shè)備的公司。具有先進(jìn)的鑿巖機(jī)具研制開發(fā)中心,擁有一支實(shí)力雄厚的科研開發(fā)隊伍,近幾年來,研制的YDT31型新型電動鑿巖機(jī)專利產(chǎn)品,填補(bǔ)了我國鑿巖機(jī)械中一次能量轉(zhuǎn)換的空白,冶金部科技成果鑒定會鑒定為“達(dá)到國際先進(jìn)水平,是對我國電動鑿巖機(jī)研制方面一個新的貢獻(xiàn)”。在致密花崗巖(f=14~16,σb=140~160MPa)中鑿速達(dá)180~280毫米/分(鉆頭直徑36mm),比一般相似機(jī)型的鑿速提高30%,較目前小型氣動鑿巖機(jī)提高70%,該機(jī)的能量利用率達(dá)53.1%,為現(xiàn)有小型氣動鑿巖機(jī)能量利用率(7.7%)的七倍,按每臺年工作300天*5小時計,節(jié)電11820度,以1000臺計,年節(jié)電1182萬度,節(jié)電效益為768.3萬元/年,不需壓風(fēng)設(shè)備和輸風(fēng)管道,借助柴油發(fā)電機(jī),在無電區(qū)域也能正常工作,節(jié)約大量基本建設(shè)資金,確保人身、場區(qū)、設(shè)備的安全作業(yè)。由此開發(fā)的系列產(chǎn)品手持式、機(jī)動式、電液式、臺車式等鑿巖機(jī)械,廣泛用于修筑公路、鐵路、機(jī)場跑道、地質(zhì)勘探、金屬和非金屬礦藏開采、國防工程等領(lǐng)域。WuhanXinwenfengMachineyCo.,Ltdisanewcompanytomajormanufacturetheminemachineryequipment.IthasanadvancedresearchcenterandaR&Dteamwithrichexperiencewithanefforttothedevelopmentandtestofrockdrillandtools.Inrecentyears,thecompanyhassucceededindevelopingthepatentproduct,YDT31NewTypePowerfulElectricRockDrill,whichhaspassedtheScience&TechnologyAchievementsExpertiseOrganizedbytheMinistryofMetallurgyIndustry,andregardedas“havingachievedtheintemationaladvancedlevelinthefieldandmadeanewcontributiontothedevelopmentofelectricrockdrillinourcountry”.Fordrillingindensegranite(f=14~16,σb=140~160MPa),thepenetrationrateisupto180~280mm/min(bitdiameter36mm),whichis30%fasterthanthatofthesimilarproducts,70%fastertheordinarysmallpneumaticrockdrills.Theenergyutilizationefficiencyisupto53.1%,whichis7timesasthatofthesmallpneumaticrockdrill(7.7%).Bycalculationofoperatingtimeas300days×5hoursforayearperdrillset,itcansaveelectricityby11820kilowatt-hours.Furthermore,bycalculationfor1000duillsets,thiscansaveelectricityupto11.82millionkilowatt-hoursperyear.Theresultingprofitonelectricityeconomizationis7.683millionyuanRMBperyear.Itneedsneitheraircompressingfacilitiesnorpipelines,andcanoperatenormallyeveninsitewithoutelectricitybymeansofdieselengineTherefore,
