康明斯发电机技术AGN 030 – 服务和维护说明书
Application Guidance Notes: Technical Information from Cummins Generator Technologies AGN 030 – Service and MaintenanceDESCRIPTIONSuitable service and maintenance are vital to the reliable operation of the alternator and the safety of anyone coming into contact with the alternator. The alternator should be inspected between scheduled maintenance, in line with inspection procedures and schedules provided by the manufacturer to identify any potential failure modes, signs of misuse or excessive wear and tear.An alternator specific Owner’s Manual (also known as Installation, Service and Maintenance Manual) is supplied with every alternator. The manuals are also published on the website. Each manual includes a Section on Service and Maintenance.The service activities are intended to maximise the life of the alternator but shall not vary, extend or change the terms of the manufacturer’s standard warranty or the customer’s obligation in that warranty.Each service interval is a guide only, developed on the basis that the alternator was installed and is operated in accordance with the manufacturer’s guidelines. If the alternator is located and/or operated in adverse or unusual environmental conditions, the service intervals may need to be more frequent. The alternator should be continually monitored between services to identify any potential failure modes, signs of misuse or excessive wear and tear. Recommended Service ScheduleThe recommended service schedule published in the manual shows the recommended service activities in table rows, grouped by alternator subsystem. Columns of the table show the typesof service activity, whether the alternator must be running, and the service levels. Service frequency is given in running hours or interval time, whichever is sooner. A cross (X) in the cells where a row intersects the column shows a service activity type and when it is required. An asterisk (*) shows a service activity done only when necessary.Service level documents referred to in the recommended service schedules can be purchased directly from Cummins Generator Technologies Customer Service Department, by telephone on +44 1780 484732 or by email: **************************************************. STAMFORD AlternatorsThe recommended service schedule for STAMFORD alternators can be found in Section 7 of the manual, with the following breakdown of sub-sections:Recommended Service ScheduleBearingsControlsCooling SystemCouplingRectifier SystemTemperature SensorsWindings.AvK AlternatorsThe recommended service schedule for AvK alternators can be found in Section 10 of the manual, with the following breakdown of sub-sections:Preventive ServicingSafety PrecautionsRecommended Service ScheduleServicing – General StructureVibrationServicing the Bearings and the Lubrication SystemGenerators with Bearing InsulationService WindingsServicing the Generators CoolerRepairs, Dismantling and Reassembly.Importance of Alternator MaintenanceThe maintenance programme is developed to meet the needs of different alternator designs. There are three types of maintenance strategies;∙Reactive maintenanceo Failure or abnormal operation.∙Preventive time based maintenanceo Time based maintenance.o Based on manufacturer’s experience.Predictive / condition based maintenanceo Maintenance based on actual measurements.A regular preventive maintenance schedule will ensure peak performance, maximize alternator life, maximized reliability and minimize breakdowns.INSTALLATION CONSIDERATIONSThe alternator must be installed in an accessible location with easy access to the main terminal box, bearing cap, air filter, louvers (inlet and outlet) and NDE/DE end brackets. The mentioned access points provide easy access to internal alternator components as shown in Figure 1. This will allow the execution of periodic inspections, local maintenance and removal of the alternator for external services.Figure 1: Internal alternator components that require periodic maintenance. Alternators LiftingDifferent alternator designs must be lifted by hooks or shackles attached to the lifting points (lugs or eyes). Chains of sufficient length, and a spreader bar if necessary must be used when lifting the alternators so as not to damage the terminal box, alternator parts and prevent the rotor from failing out on 1 bearing alternators as shown in Figure 2. When lifting entire Generating Set, the installation engineer must use specially designed Generating Set lifting points, and not alternator lifting lugs.Figure 2: Showing an example of the right and wrong alternator lifting methods. Mechanical CouplingInstallation engineers should follow the alternator manufacturer’s integration instructions provided in the Owner’s Manual. When coupling, the engineer should not attempt to rotate the alternator rotor by levering against the vanes of the cooling fan as shown in Figure 3 as the fan is not designed to withstand such forces and will be damaged. The holes of the coupling discs should be aligned with the flywheel holes by cranking the engine. Additional forces should not be put on the bearings while assembling the coupling half as it will damage the bearings.Figure 3: Alternator cooling fan vanes.SafetyIt is important to follow the alternator manufacturer’s general and local health and safety instructions. Incorrect installation, service or replacement of parts can result in severe equipment damage and personal injury. Only qualified individuals should perform electrical and mechanical component installations. Safety information signs are provided on the equipment to indicate hazards and emphasize instructions.Figure 4: Examples of the safety signs provided on an alternator. Environmental ConditionsAlternators installed in Generating Sets that are sited in arduous ambient environmental conditions may be susceptible to breakdown at their location site, if appropriate service and maintenance is not carried out. Ensuring reliable satisfactory service though, starts with careful consideration being given to the design of the ventilation systems that will be shared by both alternator and engine. Simplifying the considerations to just deciding to have a relatively simple canopy with large openings for the benefit of the engine and then considering the alternator satisfied by the fitting of low cost air filters will result in operating problems.Decisions at the Generating Set design stage about the Canopy design and airflow control must include discussions with the alternator manufacturer to ensure that the appropriate optional extra air-filter / louver kit is nominated or the IP rating of the alternator is increased and that a bespoke maintenance regime is implemented for the complete Generating Set.Refer to AGN072 – Environmental Conditions, for guidance on appropriate installation from the alternator manufacturer’s viewpoint.Alternators in Coastal LocationsFor example; an RTG Crane application is a quite unique situation. For reasons of making the alternator output characteristics suitable to power the Crane’s drive motor, combined with the duty cycle of the variable crane motor load, the alternator is usually operating with quite low winding temperatures. Whilst this low temperature situation would normally be considered to be beneficial, it does introduce a problem when the operating environment is a salt laden with a high humidity. The accepted winding temperature at which moisture is driven from the windings is some 95o C and experience is showing that RTG applications do not achieve this. So we have a winding contaminated by a salt laden atmosphere, combined with the dust and pollutants around a working dockside, plus RIC engined port vehicles adding exhaust by-products to this winding contamination problem. Add to this the humidity and moisture associated with local weather conditions, forming surface moisture on the alternator’s outhang, a winding that is not getting hot enough to drive the moisture off and we have created a winding insulation system with much reduced ‘barrier’ capabilities.The above considers the contaminants that weaken the winding insulation system. The following explains the additional electrical stresses associated with the Variable Speed Drive units used to power the various crane movements.These VSD’s are Non Linear Loads [NLL], with quite high levels of harmonic distortion. The resulting harmonic voltage distortion results in transient voltage conditions that may well be twice the peak value that the alternator would experience under normal linear load conditions.These high transient voltage spikes stress the electrical insulation system, with which a clean uncontaminated winding insulation system can cope. But a contaminated winding will find such transient voltage spikes difficult to contain, followed inevitable by the breakdown of the insulation barrier and winding short circuit.The decision to have the new alternator fitted with IP44 inlet louvers will ensure that whilst the alternator is running, the inlet cooling air is being filtered and moisture droplets are being removed by the Premaberg filter system.However the IP44 filter assembly is not really addressing all the problems of the location being in a coastal, salt laden atmosphere. The problem with salt is that it will form a moisture absorbing film of contamination on the alternator’s winding. When the alternator is working and the windings are hot, the moisture is driven off the windings surface and the insulation resistance - IR - will be high enough to ensure that no insulation breakdown or surface tracking occurs. However; as soon as the Generating Set is stopped, the alternator’s local environment becomes extremely humid, it is at this point the hygroscopic layer of salt that has formed on the windings will absorb moisture and this will result in the windings IR value being reduced to a low level and so, an inability to insulate/isolate phase to phase and phase to earth. Therefore, when the Generating Set is next started and the alternator excites to the normal working voltage - electrical pressure - there is a real risk that an insulation failure will occur as a result of insulation breakdown initiated by surface tracking.The ideal solution is to filter the salt from Generating Set cooling air. But the practicalities must include control of the humidity level of the alternator’s environment and this involves far more than the fitting of an alternator anti-condensation heater.The most successful schemes involve a fan heater bl owing several kW’s of hot air around the Generating Set ‘chamber’ to keep the humidity RH% as low as possible. Obviously, this needs an electrical power supply when the Generating Set is not running and so may well not be an easy option.There may be a way of running-on the Generating Set after its programmed service duty. This would be in a way devised to keep hot dry air circulating whilst the whole Generating Set area temperature is gradually reduced to stop the sudden increase in RH% that occurs around Generating S ets when they are stopped and left trapped in their ‘sweat box’ canopies.It could be that Generating Set’s are operating in parallel, or a Generating Set is operating in parallel with a mains supply. This then suggests an option to introduce some Generating Set environment control, because it would seem that there is always an electrical supply available. We cannot rule out that the stresses associated with miss-paralleling, or the instability of the local mains supply e.g.; micro-interruptions, will damage insulation systems and promote failures. But if the site history is one of winding failures occurring at the point/moment of starting the Generating Set ready to put the unit back into service then, from experience, we would consider saline contamination is the prime culprit.MAINTENANCE OF THE WINDING INSULATION SYSTEMThe only way to check on the condition of the winding insulation system, is by introducing a regular procedure to check the stator winding Insulation Resistance (IR) value and although not normal practice for a low voltage scheme, the Polarisation Index [PI] should be measured too, if the alternator is installed in any challenging environment. This check of IR and PI need only be carried out to the stator winding. The spinning of the rotor and the fact that it operates at low voltages means that it is not, as much, at risk.Refer to AGN015 – Testing Winding Insulation Systems for details of IR and PI testing.At the first sign that the IR and PI are low, the alternator stator winding must be cleaned.T he exciter field is another ‘at risk’ component and the fact that it operates with dc. means that it has a high risk factor due to its operation with fixed polarisation. If the exciter field insulation fails it will also take out the AVR.Cleaning windingsIf cleaning of the windings becomes necessary, then the preferred method is to completely strip the alternator to enable a thorough inspection and then a washing process, which will result in dirt removal by encouraging a washing-out of dirt by an action that will not result in the dirt being forced further into the winding assembly. The washing medium should be clean hot water applied from a directional nozzle at a pressure not exceeding 3bar.At no point should the winding insulation be subjected to a jet of water pressure that is deforming the insulation materials.For extremely oily contaminants, an alternative method is to use a hot pressure wash - not exceeding 3bar – with an added solvent based biodegradable cleaner of neutral pH. Note: ‘Autosmart’ and Aquawash’ are trade names of such biodegradable cleaners.Water-based Alkaline Detergents should not be used for cleaning as they contain ‘wetting agents’ that leave contaminants - in the form of salts - on the winding surfaces. These contaminants are hygroscopic and therefore readily absorb moisture, which will lower the insulation resistance and promote surface tracking.Caution: Inappropriate or badly executed cleaning methods will leave contamination embedded in the winding crevices and this local contamination will promote degradation of the insulation system.After the cleaning process, the windings must be slowly[over several hours] heated to at least 100degC in a thorough drying out procedure of perhaps twelve to twenty four hours. The insulation resistance [IR], phase to phase, and phase to earth, must be measured during this process.Refer to the alternator’s Owner’s Manual (Installation, Service & Maintenance Manual) for the drying out procedures and the IR test procedure, including the values, in Mega-Ohms, that thewinding must achieve before the winding IR can be said to be high enough for the wound assembly to be considered a serviceable unit.Once the windings have been cleaned and the insulation resistance improved to what is considered to be a satisfactory level, the clean and dry windings should be treated with an appropriate ‘over-coating’ electrical anti-tracking resin / varnish. This treatment will offer protection from further immediate in-service recontamination of the winding surface. The chosen anti-tracking material should be of the same insulation thermal rating as the alternator’s insulation system - Class ‘F’ or Class ‘H’.Checks must also be made to ensure that the electrical anti-tracking resin / varnish will adhere to the windings original impregnation materials.Application Guidance Notes are for information purposes only.

K |ControlMaster CM10|Universal process controller, 1/8 DINApplication templatesTo minimize commissioning time, the CM10 features up to 8 preconfigured control strategy templates. By selecting the required control strategy, the template configures the CM10's function blocks and display automatically. Customization of the preconfigured templates is also possible, providing the flexibility to create customized solutions.Single loopThis template provides standard, single loop process control and is available with or without a remote setpoint.In this example, the temperature of a product heated by a heat exchanger is regulated via the control of the steam feed to the heat exchanger.Auto / Manual station and analog backup stationThese templates configure the CM10 to backup a master controller, typically a PLC or DCS. A fault condition is detected via a low output signal from the master controller or a digital signal. On detection of a fault signal, the CM10 can take control of theprocess (analog backup template), freeze its output or switch to a safe output (auto / manual station template). In this example, a critical control of flow is backed-up by the CM10.Fig.14:Single loopFig.15:Auto / Manual station and analog backup stationTechnical specificationOperationDisplayColor, 1/4 VGA TFT, liquid crystal display (LCD) with built-in backlightLanguageEnglish, German, French, Italian and SpanishOperator keypad4 tactile membrane keysSecurityPassword protectionBasic / Advanced – user-assigned password protection (not set at factory)Standard functionsBase templates:—Single loop with local setpoint—Single loop with remote setpointStandard templates:—Auto / Manual station (low signal detection)—Auto / Manual station (digital signal selection)—Analog backup station (low signal detection)—Analog backup station (digital signal detection)—Single indicator / manual loader station—Dual indicator / manual loader stationControl output typesCurrent proportioningTime proportioningOn / OffMotorized valve with feedbackMotorized valve without feedbackSplit output – with combinations of relay, digital output and current outputsControl parametersProportional band: *—0.0 to 999.9 sIntegral: *—0 to 10000 sDerivative: *—0.0 to 999.9 sManual Reset:—0.0 to 100.0 %* 3 sets of PID parameters when used with Gain Scheduling facilityControlMaster CM10|Universal process controller, 1/8 DIN|DS/CM10–EN Rev.

康明斯康明斯发动机使用维护概要发动机使用维护概要使用说明发动机的操作者在发动机的使用过程中必须承担维护和保养好发动机的责任，以使康明斯柴油机为您提供最好的服务。
概述概述：：以下以下适用于所有用途的发动机适用于所有用途的发动机----新发动机起动前的说明1.加注燃油系统A．向燃油滤清器中加注清洁的柴油，柴油规格应符合国家标准。
B ．检查进油管路的密封性。
C ．检查并加注燃油箱。
2. 加注润滑系统A. 从增压器上卸下机油进油管，用50~60毫升干净润滑油润滑增压器轴承，再装回机油进油管。
B ．向曲轴箱中加注机油至油尺上的低（L ）和高位（H ）之间。
机油盘或发动机必须使用原配的机油尺。
3. 检查空气管路连接检查通往空气压缩机和空气设备（如装有）以及进排气系统密封性，所有的卡箍、接头都要紧固。
4. 检查并加注冷却液A ．卸下散热器或热交换器盖，检查发动机冷却液液位。
如需要予以添加。
B ．检视冷却液的渗漏清况；打开DCA 水清器的截流阀（从OFF 位置转向ON 位置）---新发动机的走合康明斯发动机在出厂发运前已在测功器上进行了试运转，因而可以直接投入使用。
但如果操作者在最初的100 工作小时内按下列条件操作，则可获得最长的使用寿命。
1．尽可能长时间地让发动机在3/4油门负荷范围以下工作。
2．避免发动机长时间怠速运转或在最大马力下工作超过5分钟。
3．养成操作时密切注视发动机仪表的习惯，如果机油温度达到121℃或冷却液温度超过88℃时应关小油门。
4．在走合期间内，每10小时检查一次机油油面。
维护和保养要求进气系统——必须确保进气系统清洁干净——检查进气系统是否有漏气的可能性——定期检查管路和卡箍有无损坏和松动——根据环境灰尘污染状况和进气阻力指示器的指示保养空气滤芯，检查空气滤芯橡胶密封圈和滤纸，保证其处于最佳状态——如果使用压缩空气清扫空气滤芯，必须由内向外吹扫，压缩空气压力不要超过500KPa，以免损坏滤芯，滤清器清洁次数超过5次必须予以更换。
★危险！灰尘进入会损坏您的发动机！润滑系统——机油推荐当环境温度高于--15°C时，使用SAE15W40，API CF4以上级别的机油；当气温在--20°C至--15°C之间时使用SAE10W30，API CF4以上级别的机油。
当气温在--25°C至--20°C之间时使用SAE5W30，API CF4以上级别的机油。
当气温在--40°C至--25°C之间时使用SAE 0W30，API CF4以上级别的机油。
——每天起动发动机前，必须检查机油液位，机油低于机油尺上的L刻度时必须予以补充——每250小时更换机油滤清器，更换机油滤清器时必须灌满清洁的机油——每250小时更换机油，更换机油时注意检查放油螺塞的磁芯，如吸附有大量的金属，请停止使用发动机并联系重庆康明斯服务网络——更换机油和滤清器时，要在热机状态下进行，当心不要让脏物进入润滑系统——只使用康明斯公司认可的弗列加滤清器燃油系统——根据环境温度条件选用高质量的优质轻柴油——每日停机后应在热态放掉油水分离器中的水和沉淀物——每250小时必须更换燃油滤清器，更换燃油滤清器时必须灌满清洁的燃油——只使用康明斯公司认可的弗列加滤清器，不要使用低质量非康明斯滤清器，否则将可能造成燃油泵和喷油器的严重故障——更换滤清器时注意不要让脏物进入燃油系统——定期检查燃油箱，一旦发现油箱脏马上清洗冷却系统——危险：当发动机还热时，不要打开散热器盖，以免造成人身伤害——每日起动发动机前，检查冷却液液位——每250小时更换水滤清器——如果环境温度低于4°C时，必须使用重庆康明斯推荐的冷却（防冻）液（已配比好），该冷却液能在--40°C以上的环境下使用，并且能够连续使用1年——将冷却液加注至水箱或膨胀水箱注水口颈部为止——发动机使用过程中水箱压力密封状况应保持良好，冷却系统应保证没有泄漏，否则冷却液的沸点会降低，影响冷却系统的性能——冷却液中必须含有适量的DCA以防止缸套气蚀和冷却系统的腐蚀和积垢操作人员正常起动要求起动马达每次运转不能超过30秒，再次起动时应等待2分钟起动后15秒内机油压力应达到70kpa，否则，立即停机检查起动后怠速运行3-5分钟后才能加负荷，否则，轴瓦等零部件会出现瞬间供油不足而造成过度磨损怠速不宜超过10分钟，长时间怠速会造成增压器漏油、缸内积碳、零部件磨损加剧等 发动机水温不要低于60°C，否则燃油会通过气缸内壁进入曲轴箱而稀释润滑油，可通过提高转速来使水温升高冬天起动后先保持怠速直到水温表指针转动或10分钟后进入运行，注意观察水温表和机油压力表的变化。
冬天使用辅助起动液时一定要精确计量。
运行要求发动机运行中要经常观察仪表，以确认发动机水温不低于60°C且不高于设定报警温度，在怠速时机油压力应大于规范值（M11为83KPa，KT19为138KPa，NT为103KPa） 如果发动机过热，应降低负荷运行，降低负荷运行一段时间还过热，则应停车检查运行中密切注意发动机下列情况的变化。
如任一项突然变化，很可能是故障的预兆，请及时检查修理□ 发动机熄火或缺火□ 异常振动□ 发动机有异常的噪音□ 发动机工作压力、温度突然变化□ 发动机排气烟度太大□ 发动机功率下降□ 机油消耗量增加□ 燃油消耗量增加□ 燃油、机油或冷却液泄漏停机要求●关闭发动机之前，应怠速运行3-5分钟，否则容易损坏增压器、活塞、气缸及其它零部件发动机运行范围发动机运行范围●发动机低于最大扭矩转速时，全油门运行不应超过30秒。
否则会缩短发动机的寿命并可能产生发动机严重损伤，康明斯发动机设计为在最大扭矩转速点以上工作最佳，因此建议在这个范围运转发动机●在任何情况下或环境中发动机都不要超过最高空车转速（发动机空载且油门全开时的转速）运转。
●汽车下陡坡时必须使用发动机与变速箱及制动器的结合来控制车速及发动机转速★ 危险！汽车下坡时不能空挡滑行，否则可能会导致车毁人亡！★ 危险！汽车下坡时不能关闭发动机的燃油电磁阀，否则可能会导致发动机机械故障！日常检查日常检查●检查机油尺的油面应在H和L之间。
若低于L，必须补充机油后才能运转发动机。
●每天排放燃油滤清器中的水和杂质●每天检查风扇有无裂纹、变形或铆钉松动，否则应更换风扇。
决不能通过盘动风扇叶片的方法盘转发动机。
● 每天检查皮带是否松紧合适，油脂不要落在皮带上。
皮带可以有小裂纹存在，但有交叉裂纹、撕裂或掉屑时就应更换，皮带表面呈现光亮表明皮带打滑应予调整。
● 检查进气管路各卡箍是否牢靠，软管连接处是否漏气。
若有，应立即修复。
● 检查冷却液液位时，冷却液温度必须低于50℃。
切勿在高温时打开水箱盖，以免造成人身伤害，也不能在高温时补充冷却液，以防铸件产生裂纹。
加注冷却液到加水口的颈部为止。
● 检查电瓶外观有无污垢，及接头有无松动和锈蚀 ● 如果是船用发动机，还应检查海水滤网警告！ 不能向冷却系统中添加任何其它的防锈剂、除垢剂和密封剂等，否则将可能导致发动机故障！维护保养人员维护保养人员每周的保养内容每周的保养内容（（包含每天的保养内容）运行250小时小时、、16000公里或6个月的保养内容此项保养项目除进行每日和每周保养的全部内容外，还包括以下内容： 更换燃油滤清器更换机油和机油滤清器★尽量不要用两侧的螺塞放油，这样放不完全。
