CC135调节系统说明书
CC135 — 13.24/0.98/0.25型汽轮机调节系统说明书136.002SM-5哈尔滨汽轮机厂有限公司2003年9月1. 概述1.1前言本机采用数字式电液调节系统(简称DEH控制系统),其液压调节系统(简称EH系统)控制介质为14.0Mpa的磷酸脂抗燃油,由一个独立的高压抗燃油供油装臵供给整套液压控制系统;而机械保安油为1.96Mpa的透平油,由机组所配的离心式主油泵供给。
每一个进汽阀门配有一个执行机构以控制其开关:其中高、中压自动关闭器执行机构(油动机)为开关型二位式执行机构(油动机);高、中压调节阀执行机构(油动机)为连续型伺服式执行机构(油动机),可以接受±40mA的阀位控制信号,控制调节汽阀的开度。
所有执行机构(油动机)的工作介质为高压抗燃油,其中高、中压自动关闭器执行机构(油动机)及高、中压调节阀执行机构(油动机)均为单侧进油,即靠油缸液压力开启阀门,靠弹簧力关闭阀门,而低压油动机为双侧进油,完全靠高压抗燃油开关。
开机时首先通过挂闸电磁阀20/RS使危急遮断器滑阀复位(挂闸),当危急遮断器滑阀油压跌落至0.45Mpa±0.45Mpa时,压力开关63/RS触点闭合,发出一个节点信号送给DEH控制系统,DEH控制系统即可投入控制;然后由DEH控制系统开启高、中压自动关闭器,高、中压自动关闭器全开后,在其操纵座下壳体上的行程开关触点闭合,发出一个节点信号给DEH控制系统,然后高、中压调节阀执行机构接受DEH阀位信号开启相应的蒸汽调节阀门,从而实现机组的启动、升速、并网带电负荷、热负荷运行。
低压透平油机械保安系统中的危急遮断器滑阀的挂闸操作是通过挂闸组件进行的,通过它运行人员对危急遮断器滑阀进行挂闸操作,使机组具备启动条件。
在抗燃油超速保护系统中布臵有两个并联的超速保护电磁阀(20/OPC-1、2)当机组实际运行转速达到或超过103%额定转速时或机组甩负荷时,该电磁阀得电打开、迅速关闭各调节汽阀,以限制机组转速的进一步飞升。

We don’t know much about alli-gator wrestling (which looks dangerous) or mud wrestling(which looks like tons o’ fun), but we do know something about diesel wrestling.We say “wrestling” because work-ing on diesel engines is different from working on gasoline engines—you don’t get as many in your bays, so you’re less familiar with them. This article is meant to change that. N exttime you “go to the mat” with a dieselengine, you may be able to demon-strate a few new “holds.”As you know, a diesel engine requires no spark plugs to fire the fuel, although glow plugs are typically used to assist engine starts in cold weather. Often, the fuel accumulates slightly before light-off occurs. This is called the delay stage .Once the delay stage concludes, the fu-el mixes with the hot compressed air in the cylinders and ignites, causing crunching blows to occur inside the en-gine. It ’s because of these crunching blows, plus the fact that the engine pro-duces far greater cylinder pressuresthan its gasoline-fed cousin, that the diesel has long been the burly power champ that produces high torque.Two Cummins EntriesSeveral contenders have climbed into the ring on the diesel light truck card.One is the Dodge Ram truck ’s 24-valve Cummins turbo diesel, an inline Six. Featuring big breathing, this en-gine produces 245 hp with the six-speed manual transmission, or 235 hp for automatics. Peak torque of 505 ft-lb comes in at 1600 to 2300 rpm.Cummins says the 24-valve cylin-WRESTLING WITH MODERN DIESELSB Y T HOMAS M ARCYWinning a bout with a diesel engine means using some heavy-duty skills. And as with any tough match, it pays to know the strengths and weaknesses of your opponent.der head design increases airflow and improves low-speed performance.The head also features vertical, cen-tered injection nozzles, which are claimed to boost combustion efficien-cy, cleanliness and fuel economy.Weigh in some electronic fuel control and you ’ve got a tough opponent.A diesel engine ’s fuel injection sys-tem must possess several characteris-tics to deliver maximum perfor-mance. These include accurate injec-tion control, high-pressure atomiza-tion, fast fuel ignition and fuel tem-perature adjustment capability.Fuel ’s fiery entry into the cylinders in the Cummins comes via a Bosch VP44 electronic injection pump and electronically controlled timing. First,the engine is cranked up for the match with an electric-powered lift (or supply) pump. Fuel flow begins as the lift pump pulls fuel from the tank and delivers it to the injection pump.As the engine spins over, the rotary,high-pressure injection pump is driv-en at half the engine speed by a sim-ple front gear train. This simplicity helps cut operating noise.The Cummins-developed ECM re-ceives information from various sensors and controls on the engine, then trans-lates that info into specific fuel quantity and timing commands that are sent to the injection pump metering control.Note that the injection pump used on earlier (1994-98) Cummins-equipped Dodge turbo diesel pickups is a Bosch P7100 inline design —what we sometimes call the jerk pump .The cam-operated six-plunger pump in the jerk pump sends fuel to the in-jector nozzles. The newer VP44, how-ever, is a rotary job with the ability to vary fuel and injection timing basedP h o t o : P a u l W e i s s l e ron input from the ECM. This pump incorporates a fuel pump control module (FPCM), which contains fu-eling, timing and diagnostic data. The FPCM communicates with the ECM to obtain information on desired fuel-ing and timing. The FPCM responds by consulting the fueling data and timing in its memory, then commands fueling and timing solenoids.The VP44 has a fuel temperature sensor inside it. The pump also con-tains a speed sensor that gives the FPCM information on the position and speed of the pump shaft. A crank-shaft reference pulse that marks TDCof cylinder No. 1 is also sent once every pump revolution. By comparing this reference pulse from the ECM to the position signal from the speed sensor, the FPCM can reference the pump ’s position to that of the engine.This allows the FPCM to adjust pump timing to compensate for small posi-tion differences between the fuel pump shaft and the engine cam. If the difference becomes too great, a fault is logged in the FPCM.The FPCM controls the timing and fueling through two solenoids located in the pump. The timing solenoid controls the position of a cam ring in-side the pump by varying internal transfer pump pressure to a cam ring piston. The cam ring has evenly spaced lobes around its inner diame-ter. The pumping plungers ride on rollers that rotate around inside this ring. The rollers follow the inner di-ameter of the ring and push the pumping plungers inward whenever a cam lobe is encountered. This builds injection pressure on the fuel trapped between the plungers. By rotating the cam ring with the timing solenoid,the FPCM is able to advance and re-tard the injection timing by makingthe rollers contact the cam lobes ei-ther earlier or later in their rotation.As its name implies, the fuel solenoid in the pump meters fuel to the injec-tors. It does this by opening a metering valve to allow fuel from the supply pump to flow into the pumping cham-ber. Once this chamber is charged with fuel, the solenoid valve closes, trapping the fuel in the chamber and allowing injection pressure to build.The fuel is routed to the correct in-jection nozzle via the pump distributor head. A port on the distributor rotor aligns with one of the six pump dis-tributor head outlet ports to distribute fuel to a given nozzle. In the cylinder head, the high pressure opens the in-jector nozzles, allowing fuel to pass in-to the combustion chamber. Once the desired amount of fuel is injected, the solenoid valve opens, causing the pres-sure in the pumping chamber to bleed down, which ends injection. The injec-tion nozzle then snaps shut.When the high-pressure fuel reaches the nozzle, the pressure lifts the needle valve against the spring ’s preset “popping ” tension. At the de-sired pressure, the nozzle pops open to let the fuel spray into the combus-tion chamber. A minor fuel leak past the nozzle needle valve enters the fu-el drain manifold in the cylinder head. The fuel in the manifold then exits at the rear of the cylinder head and is routed to the fuel tank. Fuel return from the injection pump is al-so routed back to the tank.Breathing and BelchingBoth Cummins engines —the older Bosch-equipped P7100 and the newer VP44—feature direct injection, sans precombustion chambers. Cummins claims that direct injection produces more power than precombustion chamber-equipped engines, while lowering internal heat stresses. High compression heat and fuel swirl for good combustion develop in the pis-ton ’s symmetrical combustion bowl.In the late-model Cummins turbo diesel, the valvetrain has wider lobes on the tappet face and cam, with longer push tubes. To reduce camshaft wear, an electric lift pump eliminates the need for a mechanical lift pump lobe. The standard valve springs are compatible with engine braking equipment. Top off the en-gine with an engine-matched Holset turbocharger and wastegate and you have a unit ready to rumble. For Cummins, a no-smoke entry into the fray is gained with an Integrated Air Intake Grid Heater. Using this method, white smoke is eliminated and cold-starting is improved. After warmup, compression and combus-tion efficiencies are improved by pro-viding aftercooled air to the engine.WRESTLING WITH MODERN DIESELSFor Dodge Ram trucks, the 24-valve Cummins diesel provides improved block strength and durability, with reduced noise. Also, the water pump, oil pump, cooler housings and coolant bypass are all integrated to eliminate potential leak points.P h o t o : T h o m a s M a r c yAlso, new electronic devices allow monitoring of critical engine data and diagnostic information from the ECM.For example, with the RoadRelay 4(RR4) system, you can tap into the ECM while driving. Then if a problem develops on the road, the system will display the appropriate fault code. Al-so, RR4 can remind the driver when service is due on specific items and can record up to 12 service events.Also new for the Cummins 24-valve turbo diesel is QuickCheck II, a diag-nostic read-only application that runs on Palm devices and lets you view such items as engine sensor and diagnostic information, including boost pressure,oil pressure, fuel rate, percentage en-gine load, engine hours, output torque and intake manifold pressure. The QuickCheck II kit contains a custom data link adapter, cables, connectors and the diagnostic software applica-tion. Load the software, plug it in and you can view data in real time or download it to your shop PC.Ford’s Power StrokeFord enters the ring with an old hand, but with new tricks. In its Pow-er Stroke Garrett-turbocharged diesel, such as found in an F-250 we recently drove, a mechanical fuel pump nests in the valley behind the fuel filter with its plunger riding on a special engine cam lobe.In older models, the feed pump uses a diaphragm to draw fuel from the tank while a piston-type positive displace-ment pump increases the 4 to 6 pounds of pressure to around 50 psi, regulated by a spring and plunger in the filter housing. The 50 psi is delivered to the lower chamber inside the injector through a common rail passage in the cylinder head. The tiny fuel chamber plunger ’s oil-pressure-driven head is seven times the size of the bottom of the plunger, where the fuel is delivered.The head forms the chamber floor that receives a burst of high oil pressure.This happens as an electrical solenoid valve opens and lets the pressure in.The high oil pressure pulse drives the plunger down, multiplying the pressure by a factor of seven at the injector tip. The trapped fuel blows outthe injector tip and into the cylinder.The PCM operates the injector so-lenoids through an injector driver module. The fuel comes to the sole-noids from an injection control pres-sure sensor, a sensor in the oil rail at the front of the driver ’s side head. An injection pressure regulator (IPR)rides in the high-pressure oil pump.This pump mounts similar to the old-er-design injection pump.The fuel enters both the left and right cylinder head high-pressure feed hoses. During a cold start, the high-pressure oil pump receives unfiltered oil from the low-pressure lubrication pump through the left-side valve lifter oil galley and through the antidrainbackDiesel engines need and consume large quantities of air . Always check the airfilter and examine the manometer gauge to look for restrictions.GM growls in V8 style with the new Duramax 6600. The engine features many aluminum components and an electronic common rail fuel system.P h o t o : T h o m a s M a r c ycheck valve. Once the engine starts, or during warm engine starts, the check valve closes and the high-pressure oil pump receives filtered oil from the pump reservoir. The high-pressure pump then supplies the oil under ex-tremely high pressures through the left and right pressure rails. A relief valve in the high-pressure oil pump regulates the available pressure.The control pressure actually deliv-ered to the oil rails is regulated elec-tronically by an injector control pres-sure (ICP) regulator, controlled by the PCM. Once in the oil rail, the oil is fed to the head ’s fuel injector bores through four galleys drilled and ma-chined in the cylinder head. The high-pressure oil then activates the fuel in-jectors based on PCM commands.The GMC & Chevy T ag T eamGMC and Chevrolet enter the ring with a new 6.6-liter turbocharged diesel V8called the Duramax 6600. Although no lightweight in power, the Duramax weighs only 836 pounds. It uses alu-minum extensively in such key compo-nents as the cylinder heads, crankcase,accessory drive brackets, intake mani-fold and flywheel bellhousing. The en-gine is available in 2500 HD and 3500GMC Sierras, and in Chevrolet Silvera-do pickups and chassis cabs.The Duramax cylinder head is made of gravity-cast aluminum and has four valves per cylinder. Each fuel nozzle islocated in the center of the combustion chamber in a stainless-steel holder. The valve arrangement forms a twisting in-take airflow. The intake ports are de-signed to maximize tangential flow for optimum intake swirl. In this head, ade-quately and evenly cooling the valve seats helps minimize any change in the valve gap.The Duramax fuel system has a sup-ply pump, a function block, common rails and injectors. An eccentric shaft drives the three-plunger supply pump,which is driven at crankshaft speed. The pump ’s inlet has a gear-type feed pump and a rail pressure control valve, which is governed by a sensor attached to the function block, on the high-pressure side. The valve is controlled in response to driving conditions. Each injector has a PCM-controlled solenoid in the injec-tor ’s upper portion.According to GM, one advantage of a common rail system is that injection pressure can be raised regardless of en-gine speed. This means the size of the nozzle hole in the injector can be small,which when used in conjunction with high-pressure injection, makes for a fin-er spray and faster combustion. This, by the way, makes a good case for offering timely filter services.WRESTLING WITH MODERN DIESELSWhen servicing a diesel engine, always check the maker’s specs to see what type of oil and fuel filters the engine uses. Because of the stresses of compression-ig-nition, diesels require oil with a unique lubricationcharacter and additive package.Don’t let your customer get pinned to the mat. Battery condition is a very im-portant part of any diesel’s performance, especially during cold-weather months when glow plugs help supply initial combustion chamber heat.P h o t o s : T h o m a s M a r c yThe Duramax 6600 is a relatively high-speed engine as far as diesels go,with a rated speed of 3100 rpm. Faster combustion makes possible shorter in-jection times, which means optimum fuel economy and exhaust emissions even at those higher speeds.Using short-duration, high-pressure injection improves performance in the final exhaust emissions rounds. Howev-er, because there are higher levels of NO X (oxides of nitrogen) with high-pressure injection at the start of the process, injection timing must be re-tarded. But GM says that if the timing is retarded without pilot injection, NO X reduction is limited while particulate matter increases. GM claims that pilot injection overcomes these limitations.Injecting a very small pilot amount of fuel before TDC makes it easier for the main injection to ignite. This makes it possible to retard injection timing and reduce both NO X and particulate levels.Another benefit GM claims for pilot ignition is reduced noise. Generally,combustion noise becomes louder as in-jection pressure increases. According to GM, pilot injection makes it possible to prevent a rapid increase in injection pressure during main injection, which greatly reduces diesel knock.The engine management system and control module of the Duramax are ba-sically the same as with gasoline en-gines, with vehicle-related control items also being similar. However, the com-mon rail system required developingnew software for diesel injection control items. Other new software was devel-oped for self-diagnostic items, such as injection volume, injection timing, pilot injection control, rail pressure control and injector dwell. The ECM drives the injectors by way of an electronic driver unit (EDU), which also senses and ig-nores abnormal injection requests. The engine management system also per-forms all OBD II functions.In servicing these new diesel engines,you can easily see that a technician first needs to know the basic operation of these “oil-burners.” But he must also know the quirks applicable to each powerplant. Also, training in the DTCs that an ECM/PCM can throw into the ring becomes very important.You ’d be well-advised to get a ring-side seat and do some serious manual studying on the art of diesel wrestling.Who knows? You could be called on forthe next match!Always check for proper turbocharger and wastegate function. Although tucked far beneath the cowl on this Ford pickup truck, a simple vacuum pump test can reveal a wastegate servo knocked out of the match.With a stumbling Cummins-equipped Dodge, some technicians crack open an in-jection nozzle line to check for cylinder power output. Instead, we suggest using a contact pyrometer on the exhaust manifold to isolate the offending cylinder .。

135系列柴油机的使用和调整
135系列柴油机的使用和调整一、柴油机的起动1.起动前的准备1)检查柴油机各部分是否正常,各附件连接是否可靠,并排除不正常的现象;2)加灌冷却水,添加机油至规定的油面位置,加足所需的燃油量;3)检查电起动系统电路接线是否正确,蓄电池充电是否充足;4)检查均为正常后,开启燃油箱有关筏门,用输油泵上的手泵排除燃油系统中的空气。
此时,先旋开喷油泵上的放气螺钉,然后压动手泵,直至放气螺钉处不断流出的燃油无气泡为止。
2.常温时起动指环境温度高于5℃时的起动,其起动步骤如下:1)将喷油泵供油调速手柄推到空载、转速700r/min左右的位置。
2)将电钥匙打开,按下起动按钮,使柴油机起动。
如果在15S内未能起动,应立即释放按钮,待停车2min后再作第二次起动。
如连续三次不能起动,应停止起动,找出原因并排除故障后再起动。
3)对于装有预润滑电动注油泵的机型,起动前先按动“预润滑”按钮,使油压达到0.05Mpa各油道已有润滑后,再按正常程序起动柴油机。
4)柴油机起动成功后,应立即释放按钮,将电钥匙拔回中间位置,同时注意各仪表读数,特别是机油压力表,其读数应大于0.05Mpa(当柴油机转速为500r/min),然后让柴油机在600~700 r/min的转速下运转一段时间,并检查柴油机各部分运转是否正常,例如手指感触配气机构运动件的工作情况,或掀开气缸盖罩壳,观察摇臂等润滑情况。
3.低温时起动指环境温度低于0℃(非增压柴油机)或低于5℃(增压柴油机)但高于-20℃时的起动,其起动步骤如下:1)非增压柴油机起动前应将机油加热至40℃左右注入油底壳,并将冷却水加热至80℃以上灌入柴油机,然后按常温时的起动方法进行起动。
2)增压柴油机的压缩比较低,且带有涡轮增压器,故起动较困难。
为此,进气管上有进气预热装置,起动前在柴油杯里加满柴油,将供油调速手柄推到空载、转速700 r/min左右的位置,按下预热按钮,15S后,再按起动按钮起动柴油机。
