AFHB实验室柴油颗粒过滤器XP2U Ultra Micro Balance说明书
Weighing and Analysis in the Laboratory Diesel Particulate Filters for Cleaner AirDiesel particulate filters (DPF) have been mandatory in Switzerland for all construction vehicles in use. The laboratories of AFHB in Biel are theonly one in Switzerland that approve new diesel particulate filters. The XP2U Ultra Micro Balance with filter and anti-static kit is the ideal solu-tion for this application.DPF obligation for construction vehiclesToday, many countries have implemented particulate matter limits for new on- and off-road vehicles but diesel particulate filters are obligatory for existing off-road vehicles, such as construction machines, in only a few countries. Since 2003, die-sel particulate filters are mandatory in Switzerland for construction vehicles with more than 37 kW power and the obligation was extended in 2005 to construction vehi-cles with power between 18 kW and 37 kW.30 years of experienceThe Laboratories for Internal Combustion-Engines and Exhaust Emission Control at the University of Applied Sciences (AFHB) in Biel measure exhaust emissions and approve these diesel particulate filters inSwitzerland for 30 years. In 1979, the labs started with fundamental exhaust emis-sions research and official measurements of directly imported vehicles. Today, the official measurements performed are for emission controls of all vehicles up to 3.5 t and for the retrofit systems used in on- and off-road vehicles, such as diesel particulate filters.“We test up to 20 retrofit diesel particu-late filters each year," Pierre Comte, lab manager, says. “Among Nitrogen Oxides, Hydrocarbons and Carbon Dioxide and nanoparticulates, we in AFHB measure Particulate Matter (PM)”, he continues. The particulate matter of DPF testing is sampled on 70 mm filters. First, the filter samples are prepared by conditioning for 24 hours in a clean room chamber with8NewsAcademiaAnalytical solutions in the laboratory2METTLER TOLEDO Academia News 8M i c r o B a l a n c ePublisherMettler-Toledo AG Laboratory Division Im LangacherCH-8606 Greifensee, Switzerland ProductionSegment Marketing LAB Global MarCom SwitzerlandSubject to technical changes. © Mettler-Toledo AG 08/10 Printed in Switzerland.controlled humidity and temperature and then weighed. After the sampling proce-dure, the samples are again conditioned for 48 hours and weighed. The mass of par-ticulate matter is then calculated on the basis of the differential weight. The AFHB determines PM gravimetrically by using a XP2U Ultra Micro Balance from METTLER TOLEDO.Outstanding performance The XP2U Ultra Micro Balance with filter kit is the ideal balance of choice for this application. With a readability of 0.1 μg, the differential weighing application, the tailored filter weighing kit for 47 mm and70 mm filters and the ergonomic design, the XP2U Ultra Micro Balance provides uncompromised weighing accuracy, con-sistency, convenience and efficiency. The robust stainless steel housing eliminates air turbulence and heat transfer, therefore ensuring a faster stabilization time and better weighing performance.Initial problems at AFHB with electrostatic filter loading, as result of the filter sepa-rate as handling, could easily be solved with the anti-static kit. The U-antistatic kit is driven by the balance and discharges filter samples quickly and efficiently. Be-fore the filter is placed on the weighing pan, it is passed through the U-electrode of the antistatic kit and looses all electrostatic charges.Mr. Comte and his colleague, Thomas Hilfiker, have been positively surprised by the weighing speed and fast stabilization time of the XP2U Ultra Micro Balance.The filter weighing solution enhances the speed of filter weighing and gives them more time for other important tasks. /microAn example of diesel particulate filters for construction vehicle.Mr. Comte performs filter weighing.Comprehensive Training for Thermal Analysis UsersThe new METTLER TOLEDO handbook entitled ‘Thermal Analysis in Prac-tice’ is a further publication in the Collected Applications series. The aim of the handbook is to provide practical help and training newcom-ers, inexperienced users and anyone who is interested in learning more about practical aspects in the field of thermal analysis. The handbook is also a valuable reference for advanced users and specialists.Overview of techniques and applicationsThe ‘Thermal Analysis in Practice’ hand-book describes the basic principles of thermal analysis in general. The hand-book is well-arranged to include a large number of examples and illustrations. The 327-page volume is divided into 20 chapters giving the user a comprehen-sive description of thermal analysis from definitions, basic measurement technol-ogy and methodology to an overview of the DSC, TGA, TMA and DMA techniques. It also demonstrates how the techniques can be used to measure different kinds of thermal events using METTLER TOLEDO instruments.Helpful tips and hintsThe handbook offers excellent user hints and tips concerning good measurement practice whilst providing detailed assis-tance for the evaluation and interpretation of curves obtained from different thermal analysis measurement techniques. All measurement results are evaluated using the STARe software.Standard methods andtest proceduresA large number of standard methods and test procedures are used in thermal analysis. The final chapter in the hand-book provides a comprehensive overview of many common international standard methods used for thermal analysis mea-surements.The handbook is designed with a strong emphasis on both theory and practical instruction, providing the inexperienced user with valuable information on the basic principles of thermal analysis and serving as an ideal reference book for the experienced analyst./ta3 METTLER TOLEDO Academia News 84METTLER TOLEDOAcademia News 8C l a s s i c B a l a n c eFrog Species' Survival in the BalanceOver 30 species of frogs are recorded from an area of land a quarter of the size of Scotland. Of these species, five are ‘endemic’, meaning they are found nowhere else in the world. All five endemic frogs are recognized as under threat of extinction due to the deforestation of the lush slopes of the Northern Mountain Range. METTLER TOLEDO balances play a vital role in saving these frogs from the brink of ex-tinction on the island of Trinidad.Research undertakenLittle to no research or conservation work has been undertaken on these vulnerable species since the 1970s and, with limitedfunds available in the country for bio-logical research, Trinidad’s Wildlife De-partment welcomes the input of foreign researchers to help it collect necessary information concerning the status of the species found there.During one rainy season, eleven students from the University of Glasgow, Scotland, went out to the rainforests of Trinidad to assess the endemic frog population status. Surveys were carried out in humid condi-tions in rainforest, at the edges of swamps and roadside ditches. Relative weights of species and the understanding of allome-tric trends seen in frogs offer clues as to the health of a population, without resort-ing to invasive sampling procedures.Accurate and reliable weighing In calling surveys of the forests of the Northern Range, over 200 frogs from 20 species were weighed and measured as ju-veniles, adults, tadpoles and even in foam nests in order to collect data vital to the ongoing understanding of the ecology and developmental needs of several species. Such data is necessary to inform conser-vation efforts in the future and to identify key populations to target for protection. A METTLER TOLEDO PL202-S/00 Balancewas a crucial part of their equipment.Joanna Smith, a teacher in the Univer-sity’s biology teaching centre and leader of the amphibian survey team, explains,“Its portability, reliability andaccuracy Hyla geographica, the Atlas Tree Frog(photo of the expedition team).5METTLER TOLEDO Academia News 8Marsupial (left) and Urichs frogs (photos taken by members of the expedition team).are key to the success of the monitoring work carried out in the field.”METTLER TOLEDO continues to protect frogs’ futureAs a result of the work carried out on the expedition, the University of Glasgow’s Exploration Society and the Asa Wright Nature Centre (AWNC), a local conserva-tion group committed to the preservation of the Arima Valley and surrounding ar-eas in the Northern Range have agreed to work together to improve habitat for Trinidad’s rare and endangered amphib-ians on land under the AWNC’s protection. At the same time, existing populations will be studied and changing trends noted in order to monitor their general health so that METTLER TOLEDO will continue to weigh in on the side of endangered species in the Caribbean for years to come./newclassicGolden Tree frog (personal photograph by Dan Thornham).Stream frog (personal photograph by Sandy Watt).6METTLER TOLEDO Academia News 8E x c e l l e n c e T i t r a t o rEfficient Conductometric Titration Tool for Material AnalysisResearchers in the material laboratories of a famous university in Shanghai, China use METTLER TOLEDO Excellence titrators and LabX software for conductometric titrations. The easy to use titrator replaces a tedious and error prone manual procedure.Conductometric titrationThe material laboratory carries out new nano magnetic material research. Through prior preparation steps, the researchers obtain a type of acid emul-sion particulate matter. The acidity of this emulsion needs to be tested as it hasan important impact on the subsequent processing steps. The titration has to be indicated conductometrically through the addition of alkaline titrant (NaOH).The addition of titrant neutralizes H + to H 2O prior to the equivalence point. Thus, the very high conductivity of H + is low-ered by each increment of titrant. After the equivalence point, the further addition of titrant slightly increases the conductivity again. The equivalence point is indicated by the intersection of the linear extrapo-lations of the descending and ascending conductivity curve segments.Cumbersome manual methodThe university's researchers were adding the titrant with a glass burette. After each increment, the conductivity was measured by a conductivity meter. Due to the slow reaction, this titration process cost the re-searchers too much time. The data was being recorded manually and entered into a computer for the final evaluation with calculations in Excel and other software, which all needed further time and effort in order to check-up the manual entries. Moreover, the manual titration procedure lacked accuracy and repeatability.Support from a modern solution A METTLER TOLEDO Excellence titra-tor solved the researcher's problems. The flexible method editor accommodates any titration procedure and the built-inconductivity board, a unique feature ofthe Excellence titrators, follows the titra-/one-click-titration/labxtion in real time. A One Click™ operationtouchscreen simplifies titration whilsttitrant is added automatically throughMETTLER TOLEDO's high precision bu-rettes with a resolution of 20,000 dosingsteps.This, in combination with LabX software,simplifies data management and evalua-tion.

TheMETTLER TOLEDO Excellence titratornot only completes conductometric ti-trations automatically but also mastersany other titration task. LabX softwaresupports data transfer and customer spe-cific evaluations.

and Transfer FiltrationFor Clean Diesel Applications2WhyPre-filtration?Because of the difficulties of maintaining a clean supply of diesel at all times, more consideration should be applied to upstream sources of contamination as well as at the engine. Filtering recirculation systems can be applied to storage and onboard systems, along with high efficiency filters at the dispensing pump. Careful monitoring of fuel quality and filter performance is needed to protect sensitive diesel engine injection systems.For example, the fuel used on a highway construction project may have travelled the following route:Refinery - piped to storage - tanker to distribution center - tanker to local retailer - tanker to on-site storage.Filter OptionsFBO filter systems have three filter options to meet various requirements: Particulate filter, coalescer/separator filter, or water absorber filter. For fuel dispensing applications, a coalescer/separator filter is recommended.Dispensing Filtration: FBO SeriesParker Racor’s FBO assemblies are specifically designed to meet filtration requirements of today’s high-pressure common-rail diesel injection systems.Common applications include: mobile refuelers, refueling cabinets, fuel dispensing pumps, large diesel engines, bulk fuel handling, and fuel transfer.Technical InformationProduct Features• Die-Cast Aluminum Head • Steel Bowl Assembly • P owder Coated Components • L ocking Ring Collar• 1.5” NPT Inlet and Outlet Ports• M aximum Pressure: 150 PSI (10 bar) and Maximum Temperature 160o F (71o C)• L ockable Manual Drain Valve: 1/2” NPT (part# 73225-.5)• Grounding Lug • Manual Vent Valve3Guide to help you specify the right FBO system with the accessoriesyou need.1234**Popular OptionHow to OrderF B O-10-D PFlow Rates10 = 5-25 GPM (19-95 LPM)14 = 10-30 GPM (38-114 LPM)DP = Differential Gauge DPL = Delta-P Gauge with Liquid Sight Glass MA = Marine AssemblyCoalescer/SeparatorCoalescer/separator filters are a two stage element that removes water and contaminants from diesel fuel streams and are the most popular filters.Particulate FilterParticulate filters remove contaminants down to one micron. Particulate filters can also be used upstream, before a water separator filter, to extend filter life.Water AbsorberWater absorber filters absorb water and filter out contaminants from diesel fuel.Replacement FiltersNorth America Compressed Air Treatment Gas Separation & Filtration Division Airtek/Finite/domnick hunter/Zander Lancaster, NY716 686 6400/fafBalstonHaverhill, MA978 858 0505/balstonEngine FiltrationRacorModesto, CA209 521 7860/racorHolly Springs, MS662 252 2656/racorHydraulic Filtration Hydraulic & Fuel Filtration Metamora, OH419 644 4311/hydraulicfilterLaval, QC Canada450 629 9594VelconColorado Springs, CO719 531 5855Process Filtrationdomnick hunter Process Filtration SciLogOxnard, CA805 604 3400/processfiltration Water PurificationVillage Marine, Sea Recovery, Horizon Reverse Osmosis Carson, CA310 637 3400/watermakers EuropeCompressed Air Treatmentdomnick hunter Filtration & SeparationGateshead, England+44 (0) 191 402 9000/dhfnsParker Gas SeparationsEtten-Leur, Netherlands+31 76 508 5300/dhfnsHiross ZanderEssen, Germany+49 2054 9340/hzfdPadova, Italy+39 049 9712 111/hzfdEngine Filtration &Water PurificationRacorDewsbury, England+44 (0) 1924 487 000/rfdeRacor Research & DevelopmentStuttgart, Germany+49 (0)711 7071 290-10Hydraulic FiltrationHydraulic FilterArnhem, Holland+31 26 3760376/hfdeUrjala, Finland+358 20 753 2500Condition MonitoringParker KittiwakeWest Sussex, England+44 (0) 1903 731 470Process Filtrationdomnick hunter Process FiltrationParker Twin Filter BVBirtley, England+44 (0) 191 410 5121/processfiltrationAsia PacificAustraliaCastle Hill, Australia+61 2 9634 7777/australiaChinaShanghai, China+86 21 5031 2525/chinaIndiaChennai, India+91 22 4391 0700/indiaParker FowlerBangalore, India+91 80 2783 6794JapanTokyo, Japan+81 45 870 1522/japanKoreaHwaseon-City+82 31 359 0782/koreaSingaporeJurong Town, Singapore+65 6887 6300/singaporeThailandBangkok, Thailand+66 2186 7000/thailandLatin AmericaParker Comercio Ltda.Filtration DivisionSao Paulo, Brazil+55 12 4009 3500/brPan American DivisionMiami, FL305 470 8800/panamAfricaAeroport Kempton Park, South Africa+27 11 9610700/africaParker Hannifin CorporationFiltration Group Global Headquarters6035 Parkland BoulevardCleveland, OH 44124-4141phone 216 896 3000© 2017 Parker Hannifin Corporation.

这样能有效提高发动机的工作效率和性能,防止因为杂质和污染物积累而导致的故障,同时也能够延长发动机的使用寿命。
二、滤清器的结构柴油滤清器主要由滤芯、过滤器壳体、密封圈、进出口管道和排放阀等组成。
其中,滤芯是最关键的部件,其功效在于过滤柴油中的杂质和污染物,而过滤器壳体则是将滤芯牢固地固定在其内部,并且具有很好的耐受性和封装性。
密封圈主要负责密封滤清器的连接部位,确保燃油不会泄漏出来。
进出口管道则是将柴油导入和导出滤清器,而排放阀则能够减少滤芯受到过度负荷时可能出现的毁坏。
三、滤芯的使用寿命柴油滤清器中的滤芯在使用一定时间后,就需要更换了。
使用寿命与滤芯种类、柴油使用环境等因素有关,但通常情况下,建议每行驶5000公里更换一次滤芯。
如果能够及时清洗和更换,那么可以有效避免柴油滤清器出现故障,延长滤清器使用寿命。
四、滤芯的维护保养为了让柴油滤清器能够正常运行,还需要保持滤芯的清洁和良好状态。
建议每次使用5000公里左右的时间对滤芯进行检查和清洗,把滤芯表层的污垢清理干净,可以采用清洗剂进行清洗,每次清洗切勿使用水或其他腐蚀性较强的化学物品,以免损坏滤芯,影响过滤效果。
总之,柴油滤清器对于柴油发动机的作用不可忽视,为了让发动机始终保持良好的工作效率和性能,我们必须定期检查和更换滤清器,保持其良好的工作状态。
希望大家能够认真按照说明书上的指导进行操作,让滤清器发挥出最佳的效果,为我们的柴油发动机保驾护航。

试验结束后,滤清器必须符合上述的密封性能、原始阻力、原始滤清效率的限值。
第2章柴油滤清器的材料的选择及计算2.1滤材选择考虑的因素:过滤精度原始滤清效果(柴油滤清器>90%)额定流量的原始阻力不大于9.8kPa滤芯的阻塞寿命2.2滤纸性能:容量120克/平方米最大孔径50微米平均孔径40微米透气度90格林挺度2700毫克耐破度180kpa树脂含量18%2.3滤材的选定选定0405带入公式A=n·2b·H中即A=42×2×1.2×6.3=635.04cm22.5外壳选用:选用铝质制金属外壳,表面光滑处理后,表面镀膜。
内部支撑管处小孔出带有金属丝网。
端盖采用铆合式端盖。
其厚度均为1mm。
2.6双组分聚氨酯胶粘剂粘接工艺采用粘接技术是连接材料的新工艺。
聚丙烯表面活性比较差,粘接强度较低,无法满足使用要求。
选用过硫酸铵对聚丙烯表面进行处理,提高了聚氨酯胶对聚丙烯材料的粘接强度,保证了柴油滤清器滤芯的可靠性。
聚丙烯塑料外壳表面处理,将聚丙烯塑料上、下外壳放入60~80℃处理液[m(水)∶m(过硫酸铵)=100∶8]中浸泡15~20min,取出后用干净自来水冲洗干净、烘干。
采用该粘接工艺使该柴油滤清器具有较好的密封性。
2.7柴油滤清器进出管口安装的确定滤清器的进出口管接头,其安装油管的连接采用软管接头,查表得:软管内径D=10mm,S∮=11.5mm,2.8Q=AFQ——额定体积流量,L/minA——0.00027,(min*cm2)F——滤芯有效过滤面积,cm2。
A=Q/kA——过滤面积,cm2Q——额定体积流量,L/mink——流量常数,m3/h.cm2通常取0.03A=n*2b*H=(D-d)HA=(3.14d/t)*(D-d)H=KDd-Kd2dA/dd=KD-2kd当D=2d时,A=Amax尽可能取d/D>0.5取d=40mm,D=60mm代入过滤面积A=4.0cm2滤纸滤芯参数:滤纸滤芯参数为∮4cm*6cm滤纸折宽为1.2cm高度为6.3cm0304型汽油滤芯是否有漏胶、破裂等缺陷,。
将被试滤芯装在夹持滤芯的装置上,放在装有汽油的油池4内,其时滤芯上表面最高处距油面15mm。
管路中通入压缩空气,打开开关1,慢慢打开调压阀2,观察滤芯是否有大的气泡逸出,并观察全面冒泡时U型压力计的压差值。
试验结果表明,滤芯全面均匀冒泡的压力都稳定在90一100mm水柱范围,其质量较好。
3.2液力特性试验经气泡试验合格的纸滤芯装在282型柴油滤清器内,在柴油滤清器试验台(见图)上进行液力特性试验。
试验时,将阀门6全开,启动汽油泵,逐渐关闭阀门6使滤清器最后达到一定的压差,此时记录通过滤清器的汽油量G(g)和其所需的时间t(s)。
再调整到其他压差下记录同样数据,则可测出各压差下的流量G:(kg/h)。
Gt=3.6G/t(见图)上进行了比较试验。
2内加人一定量汽油,滤清器内装人一清洁滤芯,然后打开开关4,并通过调节阀5来调节所要求通过滤清器的流量值。
调节完毕后,保持调节阀5的位置,并关闭开关4。
油箱内重新补充一定量汽油,打开开关8,搅拌油箱内汽油,然后加入称量好的杂质(GBM20氧化铝),加人浓度以重量计为千分之三。
待搅拌均匀后,打开开关4,即可使杂质油按规定的流量通过滤清器,过滤后的油收集在取样瓶内可经过上述试验进行校核,对该滤清器不足的地方进行补正。
在柴油滤清器内部,滤芯采用折叠滤纸,配合金属丝网进行过滤。
陪合过滤效果>90%,原始阻力△PkPa<9.8mPa,堵塞寿命tmin为30。
将滤清器出油口封闭,进油口连接在试验装置上试验。
以油为介质,压力不低于100KPa,保压1min,不允许渗漏。
以空气为介质,压力不低于100KPa,将滤清器置于水中,保压1min,不允许有气泡产生。
模拟实车安装方式以加速度98m/s2,振幅为±3.5mm,上下振动1h后,滤清器必须符合上述的密封性能、原始阻力、原始滤清效率的限值。
新滤清器或新滤芯的滤清器放置在盐雾试验箱中96h后取出,表面镀、涂层无起泡、脱皮,单边腐蚀不大于2mm。
将滤清器置于温度为80℃的恒温箱中1h,然后将滤清器置于低温装置中降温,在-40℃时恒温1h。
试验结束后,滤清器必须符合上述的密封性能、原始阻力、原始滤清效率的限值>3,<10。
影响:柴油滤清器是发动机的一个重要部件,滤清的好坏直接影响发动机供油系的正常工作,因而导致发动机经济性的好坏。
经调查了解,目前国产汽车发动机的柴油滤34.86g/t,多数车辆又是在没有汽油滤芯的情况下行驶,这样必然加剧了发动机的磨损。
此外,使用情况表明,由于汽油的污染使发动机产生的故障中有50%发生在供油系。
进入化油器的污垢杂质,会引起化油器通路和量孔堵塞,使省油器.加速泵工作变坏,结果使化油器工作失调,油耗增加,发动机动力性降低。
仅仅由于汽油变脏而破坏了省油器阀的密封性,就使汽油耗量增加10一20%。
又因为汽油中污垢杂质引起沉淀物数量增加,会使气门导管卡死和烧蚀气门密封面,从而降低了发动机的动力性和可靠性。
因此,柴油滤清器过滤性能的好坏对发动机的可靠性、经济性、动力性和其使用寿命均有重要影响。
二、国内外采用柴油滤清器情况1.国内情况早期国产汽车的柴油滤清器,是采用镀锌铁皮冲成斜孔然后卷成圆筒。
这种结构的滤清器效果很差,而且在汽油内水的作用下生成氧化物可直接进入发动机内,引起气缸活塞组零件的磨损。
目前,国产的轿车、吉普车、货车几乎都采用装有陶瓷滤芯的282型柴油滤清器。
由于对汽油过滤性能要求不断提高,由铜网、铜片、第4章实训总结本次课程设计是JN495-10000柴油滤清器设计。
经过一个学期的努力,我已经较好地完成了本次课程设计设计。
在设计工作开始之初,我粗粗浏览了一下题目,只觉得茫然无措,无从下手,就像仅训练了几个月的士兵就被派上战场,有种被赶鸭子上架的茫然感。
不过即使再不知所措,这课程设计也不得不做,于是我稳定了心绪,将任务书打印出来仔细研读。
在研究说明书的同时,我也参考了谭老师给的其他资料和学长以前做的课程设计成果。
在反复研究,认真思考之间,我逐渐对整个设计流程有了一个完善的概念和过程。
接下来的要做的事情就明朗起来:一步步地落实完成自己的设计流程。
我的设计逐渐步入了正轨,然后经过一个多月的奋斗,终于将课程设计完成。
回顾做课程设计的过程,一路磕磕碰碰,感觉殊不容易。
回顾全过程,原本迷雾重重,让人手足无措的课程设计,在剥茧抽丝般的理解和分析下,变得明朗而透彻。
无论什么设计,别看成果是多么的复杂,其实它都是由各个简单的阶段和步骤衔接而成。
只要你能清晰地理解整个设计流程,并严谨地完成每一个小步骤,再复杂的设计都将走下它的神坛。
这是我自前年设计变速箱之靠。
