价格:99.00
对于各种进口淮安SKF轴承,不能充分利用,延长使用寿命。这需要在日常使用过程中注意许多细节,以避免因使用不当而造成的损失。轴承也不例外。当轴承间隙过小时,***常见的情况是轴承发热,如果转速较快,可能会出现蓝色烧损现象。ForallkindsofimportedHuaianSKFbearings,theycannotbefullyutilizedtoprolongservicelife.Thisrequiresattentiontomanydetailsinthedailyuseprocessto***oidthelosscausedbyimproperuse.Bearingsarenoexception.Whenthebearingclearanceistoo***all,***'scommonconditionisthatthebearingisheated.Ifthespeedisfast,thephenomenonofblueburningmayoccur.当轴承温度升高时,应首先判断是否误操作。如果确实增加了,则应解决以下问题:Whenthebearingtemperaturerises,themisoperationshouldbejudgedfirst.Ifitdoesincrease,thefollowingissuesshouldbeaddressed:检查油标的油位是否正常,如异常,检查油箱排放阀是否关闭。如果是关闭的,应该修理。如果垫片渗油,应停止处理。取油样观察油的颜色是否发生变化,并进行老化试验。如果确认淮安SKF轴承变质,应在停机后更换.新油。Checkwhethertheoilleveloftheoilmarkisnormal,ifabnormal,checkwhetherthetankdischargevalveisclosed.Ifitisclosed,itshouldberepaired.Ifthegasketseepsoil,thetreatmentshouldbestopped.Oilsamplesweretakentoobservewhetherthecolorofoilchanged,andtheagingtestwascarriedout.IfthedeteriorationofHuaianSKFbearingisconfirmed,thenewoilshouldbereplacedaftershutdown.检查轴承是否有异常噪音,检查轴承摆动是否异常。应检查调速器的油压。如果油压低,可能导致冷凝水液压阀关闭。应检查冷凝水压力、水流和管道系统。如果水压低,过滤器可能堵塞,不能及时处理,可以停止处理。确认能正常工作后,再投入使用。Checkwhetherthebearinghasabnormalnoise,checkwhetherthebearingswingisabnormal.Theoilpressureofthegovernorshouldbechecked.Iftheoilpressureislow,itmaycausethecondensatehydraulicvalvetoclose.Condensatepressure,waterflowandpipelinesystemshouldbechecked.Ifthewaterpressureislow,thefiltermaybeblockedandcannotbehandledintime,thetreatmentcanbestopped.Afterconfirmingthatitcanworkproperly,itwillbeputintouseagain.可能是轴承油质量恶化、油本身不干净或运行中的油变质,如油中含水量增加、油酸增加、油润滑效果降低、轴瓦腐蚀、淮安SKF轴承温度升高或中断等。轴承冷凝水开启。Itmaybethedeteriorationofbearingoilquality,theuncleanoilitselforthedeteriorationofoilinoperation,suchastheincreaseofwatercontentinoil,theincreaseofoleicacid,thedecreaseofoillubricationeffect,thecorrosionofbearingbush,theriseorinterruptionofSKFbearingtemperatureinHuaian,etc.Thebearingcondensatewateropens.轴承温升故障信号发出。黑色和黄颜色指针与温度计盘(膨胀温度计)上的黄颜色指针重合或超出。侧板水轮机机械故障指示灯字板亮,指示轴承仪表温升,信号继电器动作。Thebearingtemperaturerisefaultsignalissentout.Theblackandyellowcolorpointerscoincidewithorexceedtheyellowcolorpointersonthethermometerdisk(expansionthermometer).Sideplatehydraulicturbinemechanicalfailureindicatorlightwordboardbright,indicatingbearinginstrumenttemperaturerise,signalrelayaction.热传感器可以随时监测角接触球轴承的工作温度。当温度超过规定值时,自动警报或停机,防止轴烧坏事故发生。轴承的温度可以从轴承外部的温度获得。如果油孔能直接测量进口淮安SKF轴承外圈的温度,则更为合适。Thermalsensorcanmonitortheworkingtemperatureofangularcontactballbearingatanytime.Whenthetemperatureexceedstheprescribedvalue,automaticalarmorshutdowncanpreventshaftburnoutaccident.Thetemperatureofthebearingcanbeobtainedfromthetemperatureoutsidethebearing.IftheoilholecandirectlymeasurethetemperatureoftheouterringoftheimportedHuaianSKFbearing,itismoresuitable.通常工作温度在150度以上的角接触球轴承称为高温轴承。当含铬钢温度超过150度时,其硬度急剧下降,尺寸不稳定,使轴承无办法使之正常工作。按上述要求回火的轴承钢,可在工作温度下正常使用。然而,轴承的使用寿命随着回火后硬度的降低而降低。Usuallyangularcontactballbearingswithworkingtemperatureabove150degreesarecalledhightemperaturebearings.Whenthetemperatureofchromium-containingsteelexceeds150degrees,itshardnessdropssharplyanditssizeisunstable,whichmakesitimpossibleforbearingstoworkproperly.Bearingsteeltemperedaccordingtotheaboverequirementscanbeusednormallyatworkingtemperature.However,theservicelifeofbearingsdecreaseswiththedecreaseofhardnessaftertempering.文章来自:淮安SKF轴承www.wh-Articlefrom:HuaianSKFBearingwww.wh-文章来自:淮安INA轴承a-Articlefrom:HuaianINABearinga-文章来自:淮安NSK轴承Articlefrom:HuaianNSKBearing***:524085168电话:0510-81207777手机:13311666672/13395185757)
