。检查系统零部件运转是否正常是指密切注意油泵，过滤器，冷却器，加热器，减速机运转有无异常的噪音和温升。因为减速机此时已经是带负荷运转，所以应特别注意输入轴锥轴承的温升和滑动推力轴承油池的温升有无异常现象等。Operationparametersarecheckedforcompliancewithdesign,ie.oiltemperatureandoilpressureateachlocation.Checkeachpartisworkingproperly,ie.anyabnormalnoiseandtemperatureincreaseonoilpump,filter,cooler,heater,gearreducer.Sincethegearreducerisworkingwithload,attentionshallbepaidtothetemperatureincreaseofaxialconebearingandslidingthrustbearingoilsump.所有减速机在出厂前已经在厂内进行过空载试运转，现场进行试运转主要目的是进一步观察减速机在存在一定负荷时的运行情况。Allgearreducersaresubjecttono-loadtest-runintheworkshoppriortodelivery.Thecommissioninginthefieldisintendedtocheckthegearreduceroperatingwithload.注意！电动机转向必须与减速机输入轴端盖上箭头指示的方向相一致。Caution：Rotationofmotormustbethesameasthearrowasshownoninputshaftendcover.注意！决不允许在磨煤机内无煤，而且存在加载力的情况下运行减速机。Caution：Itisprohibitedtooperategearreducerwhenthereisnocoalinthecoalmillandloadingforcepresent.停运Shutdown正常停运Normalshutdown当减速机在正常情况下停止运行时，应该先停减速机，后停润滑站。为了将刚刚停止下来的减速机内部的热量散掉，润滑站至少要延迟5分钟停止oWhenthegearreducerisrequiredtoshutdownundernormalcondition,firststopgearreducerbeforelubricatingstation.Inordertodischargetheheatinginsidethegearreducerbeingstoppedjustnow,lubricatingstationshallbestopped5minlater.紧急停运Emergentshutdown如果因为减速机事故造成减速机紧急停止运行，应立即查明故障原因并进行解决。决不允许在没有搞清问题的请况下将减速机投入运行。Ifthegearreducerrequiresemergentshutdownduetoitsaccident,firstdotroubleshootingandaddressit.Itisnotallowedtoputthegearreducerbackintooperationwithoutfindingoutthecause.维护与保养Maintenanceandservice6.1换油Oilchange换油是减速机维护与保养的重要工作之一，必须严格执行。由于磨煤机减速机的工作环境煤粉粉尘较大，温度较高，煤粉很容易从减速机输出传动法兰的迷宫缝隙处进入减速机，污染内部润滑油，使润滑油的性能下降。减速机中滑动推力轴承过早的发生磨损和烧瓦，滚动轴承和齿轮的磨损，点蚀等，均和油品的质量有关，因此，要及时换油。其次推荐的按经验的换油周期为第一次，300小时；第二次，1000小时；第三次，3000小时；以后均为3000小时/每次。Oilchangeisoneoftheimportantworksforthemaintenanceandserviceofgearreducer,whichhastobecarriedoutinaccordancewiththeregulation.Sincethegearreducerofcoalmillisexposedtotheenvironmentwithdensecoaldustandhightemperature,itisverypossiblethatcoaldustmayberoutedtothegearreducervialabyrinthclearanceofoutputdriveflangeofgearreducer,contaminatinginternallubricantandresultingindecreasedperformanceoflubricant.Prematuredamagetoslidingthrustbearingandbushing,wornrollerbearingandgearsandpitting,etc.allhavecloserelationwithqualityoftheoilbeingused.Therefore,timelychangetooilisnecessary.Therecommendedintervalforchangingoilbasedonexperienceis300hrforthe1sttime,1000hrforthe2ndtime,3000hrforthe3rdtimeand3000hreachtimelater.粗略判别润滑油是否变质的办法是按规定期限抽取油样进行观察：1.颜色变深，甚至成黑色；2.流动困难；3.在移动零件上留下褐色胶状物；4.出现沉积物或固体颗粒；5.金属表面出现腐蚀痕迹；6.散发出难闻的气味；7.必要时化验成分。Aroughmethodtoassesslubricant’sdeteriorationistosampletheoilatspecifiedintervaltocheckif1.thecolorchange,evendark;2.anydifficultmotion;3.anybrownjellyisleftonmovingparts;4.precipitationorsolidparticlesoccur;5.corrosionimprintoccuronmetalsurface;6.foulingodorisdetected.7Examinewherenecessary..以上是对减速机正常运转换油时间的规定。如果发生意外，例如，因润滑系统冷油器漏水导致油品润滑性能下降时，应及时提取油样，送到专门的技术部门对油品进行鉴定，确保用油质量。Theaboverequirementsareappliedtointervalforchangingoilforgearreducerundernormaloperation.Ifanyunexpectedthingshappen,suchaslubricatingperformanceofoilbecomeworseduetowaterleakfromoilcooleroflubricationsystem,exercisetimelysamplingandsendthesampletotechnicaldepartmentforevaluationtoensurethequalityofoil.换油时还要注意的是所换油品不仅要求符合有关国家标准规定，还要与以前运行中的一致。两个厂家生产的牌号相同的润滑油不得混用°Duringoilchange,precautionshouldbetakentoensurethatthenewoilshallbenotonlyinlinewiththenationalstandard,butbeconsistentwiththepreviousone.Sametypeoflubricantfromtwodifferentmanufacturersarenotallowedtobeusedatthesametime.换油工作也可利用润滑站上的油泵进行，此时需要打开油泵后面的三通法兰，接上排油管向夕卜排油。Oilchangingcanbecarriedoutonoilpumpinthelubricatingstation.Opentriple-flangedownstreamofoilpumptoconnecttooilsupplyline.换油时，减速机内部的残油必须彻底排放干净，以利于新油有较长时间的工作寿命。残油的排放可由减速机尾部的阀门和推力轴承油池的放油阀门来进行。Beforeoilchange,residualoilleftinthegearreducermustbefullydrainedtobenefitthelongerlifeofnewoil.Residualoilcanbedrainedviavalveattherearofgearreducerandoildrainvalveinthrustbearingoilsump.换油时，如果发现减速机内过脏，应开启润滑站对减速机进行清洗。清洗油最好采用减速机工作用油，并排放干净
