In some cases these aqueous washes can affect the cure and performance of the adhesive.This product is not normally recommended for use on plastics (particularly thermoplastic materials where stress cracking of the plastic could result). Users are recommended to confirm compatibility of the product with such substrates.Directions for use:For Assembly1.For best results,clean all surfaces (external and internal)with a LOCTITE ® cleaning solvent and allow to dry.2.If the cure speed is too slow,use appropriate activator.Please see the Cure Speed vs.Activator graph for reference.Allow the activator to dry when needed.3.To prevent the product from clogging in the nozzle,do notallow the tip to touch metal surfaces during application.4.For Thru Holes ,apply several drops of the product ontothe bolt at the nut engagement area.5.For Blind Holes ,apply several drops of the product to thelower third of the internal threads in the blind hole,or the bottom of the blind hole.6.For Sealing Applications ,apply a 360°bead of productto the leading threads of the male fitting,leaving the first thread free. For bigger threads and voids,adjust product amount accordingly and apply a 360°bead of product on the female threads also.7.Assemble and tighten as required.For Disassembly1.Remove with standard hand tools.2.In rare instances where hand tools do not work becauseof excessive engagement length,apply localized heat to nut or bolt to approximately 250°C. Disassemble while hot.3.Apply localized heat to the assembly to approximately250°C. Disassemble while hot.For Cleanup1.Cured product can be removed with a combination ofsoaking in a Loctite solvent and mechanical abrasion such as a wire brush.Loctite Material Specification LMSLMS dated June26,2009.

某型螺旋桨典型故障分析及排除

某型螺旋桨典型故障分析及排除

某型螺旋桨典型故障分析及排除杨兆军【摘要】我国近60%的通航活塞飞机均装备某型恒速螺旋桨,选取该系列螺旋桨对飞行安全影响大、发生次数多、维修费用高的两种典型故障,在分析其失效机理基础上,提出具体的解决措施,经监控和反馈数据表明,这些措施有效的降低了此类故障的发生率.【期刊名称】《技术与市场》【年(卷),期】2016(023)006【总页数】2页(P75-76)【关键词】螺旋桨;故障;甩油脂;不变距【作者】杨兆军【作者单位】中国民航飞行学院飞机修理厂,四川德阳 618307【正文语种】中文我国通航活塞飞机广泛装用某型恒速螺旋桨,随着近几年通航的迅猛发展,通航所属的飞行训练学校、企业剧增,飞机数量和训练量成倍增长。

根据授权的维修站统计,近几年该型螺旋桨故障逐年递增,最典型的是甩油脂和不变距故障,该类故障对飞行安全影响大、发生次数最多、维修费用高,对飞行员和用户造成很大的安全和经济压力。

部分螺旋桨刚装机飞行几十小时,就出现了甩油或不变距故障,而不得不拆桨送厂检修,致使飞机停场,由此造成更大的经济损失。

通过对维修记录的统计和分析,本文选取了两种该型恒速螺旋桨的故障作为典型故障来分析和研究,并期望该型螺旋桨用户能够利用本文的研究成果,降低螺旋桨的故障率,以降低训练费用,确保飞行安全。

1)甩油脂故障,又分为:桨叶根部与桨毂配合处甩油脂;前、后两半桨毂桨根接缝处甩油脂,如图1。

2)不变距故障,是指螺旋桨不变距或变距范围小于厂家规定值。

1)由于螺旋桨在高速旋转中会与空气中小的尘埃、杂质以及跑道上沙粒碰撞,加之螺旋桨本身的振动,这样会在桨叶表面上产生小的损伤和疲劳层。

翻修螺旋桨时,必须对桨叶表面进行打磨抛光处理,去除一定桨叶材料,并且对桨根部分进行滚压,致使桨根直径变小。

多次翻修后导致桨叶根部与桨毂之间配合间隙增大,密封件的拉伸量和压缩率减小,密封失效。

螺旋桨高速旋转时,桨根轴承内的润滑脂在离心力的作用下,在该处向外甩出。

光照度测量仪 LumiTop 2700 4000 产品说明书

LumiTop 2700/4000 Spectrally enhanced imaging colorimeter\\ L ab specs meet production speedThe LumiTop 2700/4000 combines the accuracy of Instrument Systems’ well-known spectroradiometers of the CAS series with the obvious advantages of imaging colorimetry. Principle: Fast and accurate With the help of a polarization insensitive, three-way beam splitter, the LumiTop 2700/4000 mergesan RGB CCD/CMOS camera anda flicker diode with the high-end spectroradiometer of the CAS series. This innovative design allows for simultaneous measurements of all components, which may result in significant time-savings.At the same time, the extremely accurate spectral information of the spectroradiometer measurement is used as reference for the camera measurement. This guarantees spectroradiometric accuracy across the whole 2D image.As a result, the LumiTop 2700/4000 not only performs fast 2D measurements with unprecedented accuracy but also offers all the advantages of classical imaging colorimetry. Perfect for productionBecause of this combination, theLumiTop 2700/4000 is perfectfor use in display productionlines or quality control, where thebenefits and capabilities of both,the accurate spot measurement ofspectroradiometers and the lateralresolution of camera measurementsare highly valued.All-in-one solutionMany different test applications cannow be organized in a single teststation:y M easurement of luminance andcolory E valuation of color and luminanceuniformity or Mura effectsy P ixel metrology including pixeldefect analysisy C ontrast measurementy A nalysis of white balance or colorgamuty F licker and luminance modulationmeasurementy A nalysis of the acquired spectraEasy to integrate intoproduction linesThe LumiTop 2700/4000 isintegrated in Instrument Systems’comprehensive new software“LumiSuite”, which comes witha user-friendly GUI for laboratoryapplications and a powerfulsoftware development kit for easyimplementation into any productionline. The spectra measured asreference for the camera can beanalyzed in more detail usingInstrument Systems’ well-knownsoftware SpecWin Pro.Independent of displaytechnologyDue to the high absolute accuracyof the CAS spectroradiometer thatis used as reference during eachmeasurement, the performanceof the solution is excellent for anydisplay technology (or any otherhomogeneous samples). Moreoverno golden sample or user calibrationsare needed. This makes the solutionparticularly favorable when OLEDs orother narrow-banded light sourceshave to be investigated where classicalimaging colorimeters based on XYZfilter technologies reach their limits.ModularityThe LumiTop 2700/4000 is designedas a modular accessory to any of thespectroradiometers of the CAS series.Thus the same spectroradiometerscan also be used with the telescopicoptics TOP 150 or TOP 200.\\Technical specifications1)Inclusive lens and fiber exit.2)Without CAS, with mode mixer.3)E xternal neutral density filters on the lens (OD 0.3/0.6/0.9) are available for increasingthe upper measurement limit or measuring modulated light sources.4)L ower measurement limit based on a signal to noise ratio of 10:1 for maximumexposure time (60 seconds LumiTop 2700 / 10 seconds LumiTop 4000). Uppermeasurement limit based on a signal level < 80 % for a white (non-modulated) LED light source using for minimum exposure time (1 ms LumiTop 2700 / 27 µs LumiTop 4000).5)T ypical value for maximum deviation over the FOV relative to the CAS spot;calculated for an image with 16 pixels (LumiTop 2700) / 21 pixels (LumiTop 4000) cropped at each edge and 10 by 10 pixels (LumiTop 2700) / 13 by 13 pixels(LumiTop 4000) binning (34 averages) immediately after calibration with reference used for flat-field correction.6)2σ of repeated measurements of one instrument (L ≈ 100 cd/m2, autoexposure).7)R NU (response non-uniformity) is defined as 99.7 % percentile of the deviationof the mean image value; calculated for an image with 16 pixels (LumiTop 2700) /21 pixels (LumiTop 4000) cropped at each edge and 10 by 10 pixels (LumiTop 2700) /13 by 13 pixels (LumiTop 4000) binning (34 averages) immediately after calibrationwith reference used for flat-field correction.8)T ime between beginning of two subsequent measurements using the SDK;determined with a camera exposure time of 20 ms and CAS exposure time of200 ms for a white LED (L ≈ 500 cd/m2). Depends mainly on PC processing capability.9)L ower measurement limit based on a signal to noise ratio of 10:1 for maximumexposure times 65 s for CAS 140D and CAS 140CT, 20 s for CAS 120. Uppermeasurement limit based on a signal level < 80 % for a white (non-modulated) LED light source using a CAS internal optical density filter OD4 and minimum exposure time (10 ms CAS 140CT / 4 ms CAS 140D and CAS 120).
