GeneralThe water cooler is a finned tube heat exchanger .The hot air flows through the fins on the outside of the tubes and the cooling fluid flows through the tubes. The heat exchanger surface of the cooler consists of elliptical core tubes with rectangular threaded on fins or round core tubes with either wound-on fins or continuous flat plate fins. The bond between fin and tube is achieved either by mechanical means or by soldering.The core tubes are rolled into the tube sheets at each end of the tubes with roller.Side wall form an integral part of the cooler and are bolted to tube sheets.Water Headers (Namely connection and Return headers) are provided for water handling. The number of separation baffles conforms to the number of water passes. The headers are bolted to the tube sheets, gaskets interposed to form a seal. Plugs in the header are provided for cooler venting and draining.The materials for headers, tube, sheets and core tubes are chosen in accordance with the specification of the cooling water to be used and the recommended water velocity in the tubes.2.Installation and removal of the coolerRead all the maintenance instructions before you begin bundling this product.The cooler should be installed where it is accessible for cleaning, but not where the general public has access to it. Only let trained personnel with profound knowledge of the product and the appropriate safety rules carry out any work on the cooler.Prior to installation of the cooler ,the transport covers of the air side and the blanks on the water connection flanges are to be removed .The air and water side sealing surfaces ,which areprotected priot to shipping, must be cleaned by the use of turpentine.The cooler can either be mounted to the engine as a self mounted in the air duct as a cantilever unit. The air side connections are bolted to the air ducts using gaskets or sealing compound provided by the engine builder.The cooling water pipes are bolted to connection flanges on the connection header using gaskets also provided by the engine builder.To avoid deformation and stresses when installing the cooler all connecting surfaces must be parallel and the tolerances should be kept as small as possible.All connections are to be air and water tight. Transport lugs are provided on the side walls forlifting and handling of the complete cooler. Lifting lugs are also welded to the tube stack side walls. Prior to installation of the cooler casing into the air duct the tube stack can be removed by means of unscrewing the bolts holding the protruding tube sheet to the casing frame and removal of the gland packing or cover plate at the extension end tube sheet. At the fixed end of tube stack threads are provided in the water header for eyebolts to be used when lifting and pulling out.3. CommissioningThe cooler is subject to a hydraulic pressure test in our factory. It is however recommended to carry out a test with the specified test pressure before installation.If after prolonged storage or extended standstill the geared gaskets are leaking, tightening of the geared bolts might prevent further leakage. If this is not sufficient the header gaskets must be replaced. A pressure test with specified test pressure should be carried out after replacement.When refitting the headers ,tighten the bolts in the order .Tightening torque :70NmAfter assembly of the cooler is completed the cooler is circulated with the specified cooling water quantity prior to venting.For cooler venting, the vent plugs in the headers are removed. After the air has escaped from the cooler the plugs are fitted again. Venting should be repeated shortly after cooler is taken into operation. Venting of the complete cooling system is better than venting only thecooler and should therefore be preferred.With multi-circuit or multi-stage coolers, each circuit or stage should be vented separately.After a leak test has been carried out on all plant components, and the water flow has been checked to en-sure there are no restrictions, the cooler can be put into operation.Upon accelerating the engine to the nominal load the air temperature should be measured before and after the cooler and the cooling water flows set in accordance with the nominal water flows stated in the performance data sheet for the cooler in question.Never operate at min. velocity for a prolonged period of time. The nominal water flow stated in the performance data sheet for the cooler in question should be maintained.Frequent fluctuation of the water velocity impede the formation of a protective film on the tube inside, which are vital for corrosion protection. A too low water velocity encourages dirt deposits and a too high velocity causes erosion. To throttle the water flow or improper position of the water intake could lead to oxygen enriched water which favors corrosion. To keep the water flow, and so the watervelocity, constant also during part load operation ,control devices should be installed.4. Protection filmMeasures to assure the formation of a strong and durable protective film.The inherent good chemical corrosion-resistance of cop-per and copper alloys is due to their ability to form a natural protective film which is difficult to dissolve.New cooler tubes lacking a sufficiently strong protective film should never be operated with contaminated water, as deposits on the material surface would prevent the formation of such a protective film.For the above reason clean fresh water is used for the hydraulic test of the heat exchanger. The utilization of contaminated water should also be avoided during test runs. During test runs it is recommended to add small quantity of easily soluble ferrous sulphate (FeSO4.7H2O) to the cooling water to make sure that a good protective film is formed before operating with contaminated water.It is sufficient to add about 5mg/l to cooling water during a period of one hour every 24 hours. Adding of ferrous sulphate should, if possible, be repeated during normal operation until the first inspection is carried out.An appropriate valve for adding ferrous sulphate should be provided in the piping close to the water inlet nozzle of the cooler.5. StandstillA standstill of the cooling water system, leaving the cooler undrained, is hazardous for cooler parts made of copper , copper alloys, steel and cast iron.For copper and copper alloys standstills are especially hazardous prior to the formation of a protective film or in the case that the destruction of the same must be feared for reason of deposit attacked by putrefaction products such as ammonium compounds and hydrogen sulphide.If possible, cooler operation should not be interrupted during the first 2 months after commissioning if the cooler can not be drained.However, if there is a failure in cooling water supply and operation is resumed within 3 days and then for a prolonged period of time kept uninterrupted, the cooler may be left undrained.It must be then guaranteed that the tubes are free from deposits. If deposits have formed, the cooler should be drained, the tubes cleaned and flushed with clean water prior to being dried. We recommend the use of warm or pre-dried air for blowing through the tubes.The coolers need to be vented adequately. If sea water, brackish or saline water(chloride content>500mg/l) is used as cooling water, water with low salinity (drinking water quality)should be used for flushing. In case of standstill within the start-up period of 2 months which is expected to last for more than 3 days, and where deposits must be feared, the cooler should be drained, flushed and dried.To avoid standstill corrosion after the first 2 months of operation the above described cleaning procedure should be repeated by every standstill lasting longer than 2 weeks.In case of permanent service interruptions after the start-up period it may be necessary to limit the standstill where the cooler is kept undrained to 3 days and operate the unit under conditions as recommended for the start-up period.During short standstill the cooler can be operated at low cooling water velocity soformation of deposits in the tubes can be prevented. Operating with low water velocities is to be preferred to cooling water standstill in the tubes as putrefaction products, such as ammonium compounds and hydrogen sulphide are washed away from their point of origin.During winter time standstill if frost injury to the cooler could occur the cooler should be drained also during the shortest standstill.6.Service control6.1 GeneralFor service control, thermometers are to be installed in the air ducts and in the cooling water piping before and after the cooler, we recommend to keep record of the air and water temperatures in the machine log book periodically. Further control instruments can be provided in accordance with the individual requirement.In case of the occurrence of a major amount of condensate after the cooler, further condensation can be prevented ,or at least limited, by the use of a bypass control of the cooling water as previous described.A possibility to drain the condensate must be assured.6.2 Performance testThe performance guarantee given is main expressed by the temperature difference between cold water and cold air during normal operation and should be checkedfrom time to time.In the event that a considerable increase of the guaranteed temperature difference observed during normal operation ,this might be due to accumulation of air in the cooler. To remedy the above the cooler should be vented by using the procedure previously described.In case a performance increase cannot be achieved by proceeding as above and provided no other disturbance can be found , the cooler needs cleaning.A differential pressure gauge can also be used to check whether or not cleaning of the air or water side of the cooler is necessary. We recommend to install differential pressure gauges in the air duct and water piping before and after the cooler.7. Cleaning7.1 GeneralCleaning of the water and air side heat exchange surfaces is imperative for a long and trouble free operation of the cooler. The cleaning intervals vary with the mode of operation, cooling water quality, intake air characteristics etc.Cleaning can be done by either mechanical , hydraulical or chemical means.7.2 Cleaning of the water sideRegular cleaning is necessary. The cleaning intervals depend on the cooling water used. Cleaning of the water side is not only required to maintain the thermal performance of the cooler. Scaling increases the risk of biting corrosion and obstacles partly blocking the tubes favors erosion.7.2.1 Mechanical cleaningMechanical cleaning is done by use of nylon brushes fitted to a rod. The length of the rod corresponds to the tube length of the cooler in question and the type of brush is chosen in accordance with the finned tube type. The brush with rod is part of each cooler delivery.Mechanical cleaning can be done insitu or with the cooler removed. At least one header needs to be removed when cleaning. For header removal threaded holes with the same dimension as the header bolts are provided in the header flange to serve as jacking screws. The wet tubes should be thoroughly brushed clean one after the other and the dirt flushed out until no residues are left. After the cleaning is completed the headers are refitted using new gaskets. Venting must be repeated after cooling water is refilled7.2.2 Hydraulic cleaningHydraulic cleaning is carried out with the cooler removed using a high pressure spray gun with special nozzle to remove dirt deposits inside the tubes.7.2.3 Chemical cleaningChemical cleaning can be carried out in-situ or with the cooler removed.7.2.3.1 Chemical cleaning In-situTo ensure that the cooler is always operated without fouling or scaling in the tubes we recommend an integrated and continuously operating chemical cleaning system to be fitted.Such cleaning system comprises of a circuiting pump and a detergent tank with the necessary piping and shut off valves. The detergent circuit is connected to the cooling water inlet and outlet piping between their shut off valves and the water header flanges.Prior to cleaning, the cooling water flow is interrupted to allow the cooler to drain via the cooling water outlet piping. For draining the vent screw are removed. After draining, the cooling water valves are closed. The valves of the cleaning circuit are opened and the circulating pump switched on. The vent screws are fitted after venting completed.It is recommended to connect the cleaning circuit to the cooling water outlet piping in such a way that the deter-gent flow is opposite to the normal cooling water flow.When cleaning completed the cooler is drained leaving no detergent in the cooler. The valves of the cleaning circuit are closed and the cooling water valves opened. Flushing is done with normal cooling water. Reventing of the cooler is necessary.Scaling deposits in the cooling tubes can be removed by chemical cleaning as well. For removal, a 10% HCL hydrochloric, or muriatic acid is used and a 0.5% inhibitor (specifically suitable for the individual tube material added.After cleaning, the cooler is to be flushed thoroughly, i.e. no detergent residues are allowed to be left in the cooler.This is most important in case the cooler is shut down for a short time after cleaning.If the cooler is chemically cleaned in mounted position the headers need not be dismounted. For chemical cleaning we recommend to use suitable detergents to clean:The instructions and handling guidelines provided by the manufacturer of the detergent in question should always be observed when using the chemical.7.2.3.2 Chemical cleaning Cooler removedChemical cleaning while the cooler is removed is required if neither mechanical or hydraulic cleaning proved successful and if the cooler is not connected to a continuously operating cleaning system.The complete cooler with attached header will be connected by the use of blind flanges to an external cleaning circuit or filled with detergent on the water side. Time of saturation depends on the grade of deposit. If the result is not satisfying, cleaning should be repeated.7.3 Cleaning of the air-side7.3.1 GeneralCleaning of the air-side should be done early enough to avoid accumulations of soot and oil on the fins, which after a period of time form a hard crust that is difficult to remove, as well as the deposition of other crack products as for instance residues that form a sulphuric acid (compound with condensate) when left on the fins and tubes for some time.7.3.2 Hydraulic cleaningHydraulic cleaning is effected when the cooler is removed .A high pressure spray gun as described above is suitable also for this requirement. We recommend a nozzle size of 3mm. If the water jet attacks the cooling tubes vertically, i.e. in parallel to the fins, a pressure of 120bar is suitable to be applied at a distance of 2m from the fin surface.7.3.3 Chemical cleaningWe recommend chemical cleaning of the air side while the cooler is removed.The water headers are detached from the cooler bundle .The tube bundle is then immersed into a chemical cleaning bath. The time of immersion is a function of the degree of fouling. When cleaning completed, the cooler is to be flushed by applying a powerful water jet. If the result isstill not satisfying, cleaning should be repeated.To intensify the cleaning effect of the bath and shorten the cleaning time, it is recommended to circulate the detergent. The chemical detergents can also be applied by spraying. The following detergents are recommended for air side cleaning.The instructions and handling guidelines provided by the manufacturer of the detergent in question should always be observed when using the chemical.。

Therefore, the length of the externalpiping should be minimized and internal diameter should be as large aspossible. Piping must have sufficient strength for the maximumdischarge pressure of the circulating circuit.Likewise, if a tube is bent or multiple elbow fittings are used, the pipingresistance will increase and the flow rate will decrease. If the flow ratefalls, the temperature stability will decrease.If installing a tank externally, only a sealed tank should be used. Do notuse an open tank.Normal When high head pump option selectedNormal When high head pump option selectedNormal When high head pump option selectedNormal When high head pump option selectedEnsure that the INLET and OUTLET for circulating fluid is connected correctly. If any valves are used ensure that they do not restrict the flow, otherwise low flow may cause an alarm.When installing piping or fittings, ensure sealant material does not enter inside the port. When using seal tape, leave 1.5 to 2 threads exposed on the end of the pipe/fitting.Be sure to correctly tighten the fitting fittings to the required torque(Rc1/4:12 to 14 N ･m, Rc3/8:15 to 20N ･m). 5.5 WiringEnsure that the power source and the power supply of the product is turned off before connecting the various connectors and power supply cable.Supply disconnecting device according to IEC60974-1 and IEC60947-3 for the product must be provided in the end system.Do not install the disconnecting device in the place where the operation is difficult. And also the switch of the disconnecting device must comply with the direction of the switch specified by IEC60447. Preparation and wiring of power supply cable 1) Strip the sheath from both ends of the cable.2) Disassemble the power supply connector. Crimp one end of the cable to L, N, E inside of the connector, then reassemble the power supply connector.3) Connect the other end of the cable to a plug or terminals (e.g. crimped terminal).Ensure that there is enough space between the power supply cable and the communication cable of the product and power cables of other equipment.Ensure the power supply and ground connections are made correctly. Be sure to provide the grounding. The PE line of the power supply cable is available for grounding. Do not connect the ground in common with the ones for equipment that generates strong electromagnetic noise or high frequency.When an external temperature sensor is connected, connect the sensor with a shield cable.

Ensure that the power source and the power supply of the product is turned off (or the power plug must come off).2. Remove the reservoir cap.(When setting the product again, confirm the level of fluid does not exceed the “H ” mark)3. If using Ethylene Glycol, refer to the suppliers Material Safety Data Sheet (MSDS) and wear Personal Protective Equipment (PPE) as appropriate.4. Fill the circulating fluid into the reservoir. Stop filling once the level of fluid reaches the “H” mark.5. Turn on the power switch to fill the piping with the fluid.6. When the piping is filled with the circulating fluid, the level of the reservoir decreases and low fluid level alarm (ERR20) arises accordingly. Then, turn off the power supply once again.7. Repeat the step from 4 to 6 until ERR20 alarm doesn’t appear anymore. 8. Then, replace the cap on the reservoir and tighten it securely. 9. Keep the fluid level between H and L of the level indicator.Never touch the power switch with wet hands to avoid electrical shock.Do not touch the surface when the set temperature is high. Temperature of the tank and the chassis near the tank could be high.Fluid other than water or Ethylene Glycol (up to 20%) should not be used as circulating fluid. Using such fluid may lead to leakage or damage of the pump.Operation of the pump with a large amount of air left in the piping for prolonged period may damage the pump. Remove air from piping before starting operation.If the power switch is turned on without circulating fluid, the pump could be damaged.Take care not to spill water over the product when supplying water to the reservoir. When a spill is made, wipe it off immediately and only supply power after it has dried. If this procedure is neglected, it may cause damage to the product.If a fluid with low conductivity such as DI water is used as circulating fluid, it can cause static electricity due to friction and damage the product. Take measures to minimize the static electricity from circulating fluid. If the product is operating for a long time with large temperature fluctuations after reaching the set temperature, the product may be damaged. Please set the PID values by using the auto-tuning function.6 Operation6.1 Power UpWhen power is turned on, the software version is indicated on display panel for approx. 1 second. 6.2 OperationThe product begins operation immediately after the power is turned on.

空分冷冻机组操作及维护
空分冷冻机组操作及维护一、说明机组设计成单独使用，通过约克管理系统或其它自控系统与其它设备配合使用。
运行时，机组控制器监控冷冻水系统的温度，并发出恰当的指令，将温度维持在设定的范围内。
压缩机根据冷负荷调整运行，使机组制冷量与冷冻水系统的冷负荷相匹配。
从冷冻水中带走的热量最终由水冷式冷凝器排走。
二、启动确认机组和控制中心的电源已接通，所有的制冷剂检修阀均打开（逆时针旋转），并且冷冻水流量正常（除非采取了机组冷冻水泵停机控制，如果是这样的话，仅确认水泵电源接通即可）。
确认微处理器控制板上的系统开关（系统1或2）处于接通的位置。
按下键盘上的状态键，然后将键盘下面的机组ON/OFF拨动开关切换到接通（ON）的位置。
控制器将作一次预查，以确认日常/节假日时间表和任何一远程联锁装置均允许机组启动，所有的安全切断值都得到了满足，并且有冷负荷要求机组运行（即冷冻水温度超出了设定极限）。
如果预查时遇到问题，将会显示出来，没有问题而又有冷负荷的话，超前压缩机启动。
滞后压缩机的反重合启动定时器的状态将显示出来，后面跟着“无冷负荷”信息，直到控制系统要求它运行为止。
三、正常运行和停机一旦机组启动，所有的操作均为自动的。
经过初始的超前压缩机最小容量阶段后，控制系统将按冷冻水温度和温度变化的速率来调节机组的负荷。
如果冷负荷较高，控制器将增加超前压缩机的容量，并启动其它的压缩机；如果冷负荷较低，超前压缩机将持续在最低容量下运行，或者干脆停机，以免使冷冻水温度过低。
当出现后面这种情况时，待冷冻水温度再度上升后，超前压缩机将自动再启动。
一旦压缩机运行，随着制冷剂被压送到水冷式冷凝器中，排气压力将升高。
压缩机一运行，控制器将监控油压、电机电流和系统的其它各种参数，如排气压力、冷冻水温度等。
一旦出现任何问题，控制系统将立即采取相应的措施，并显示出故障的性质四、停机在任何时候，只要将键盘下面的机组ON/OFF拨动开关切换到断开的位置，就可以使机组停机。

安装完毕后向空冷器内充水以排气，排气时将端 盖上的放气塞卸下排气，排气完毕后再将其安装回原 处。
空冷器投入使用后，要立即排气数次。把整个冷却 系统的空气排出比只排出空冷器的空气效果要好些， 因此最好是排出整个冷却系统的空气。
多回路或多级空冷器，每个回路和每级都要单独 排气。
整个设备检测无渗漏，并保证冷却水畅流无阻后， 空冷器便可投入使用。
２．２ 空冷器的安装和拆卸 在安装空冷器前，应先拆卸下进、出气侧和水管 连接法兰上的罩盖物 ；并用松香水洗去用于保护气 侧和水侧密封面的保护物。
空冷器既可以直接安装在发动机上，也可以悬 置安装在风道中。空冷器气侧连接孔与风道连接孔 用螺栓联接坚固，同时加装发动机供应商提供的密 封材料。
空冷器进出水法兰与冷却水管用螺栓联接坚固， 同时加装发动机供应商提供的密封材料。
在发动机加速到正常负载时，测量空冷器进气和 出气温度，并根据性能数据表中的流量要求，调定冷却
水达到正常流量。

１ 、概 要
ＧＥＡ 增压空冷器是一种管片式热交换器。其工 作原理是：高温增压空气流散经散热片，将热量通过 对流作用传递给冷却管外壁，然后经过壁的导热作 用传给管内壁，再由管内水的对流作用把热量带走， 以完成换热。

空冷器决不能在最小水流速下长期工作，应按性能
数据表中标定流量维持空冷器供水。
ＧＥＡ空冷器在出厂前都进了水压试验，并检验合 格。然而，我们还是建议用户在安装前要按标定的测试 压力对空冷器进行压力测试。
如果库存期或停用期超出了规定范围，端盖的密 封垫可能会有渗漏现象。这时可通过拧紧螺栓来防止 渗漏。倘若拧紧螺栓不能解决问题，就应考虑更换新密 封垫。更换新密封垫后，要在规定的测试压力下再进行 压力测试。
安装完毕后若要拆卸管组，可先将固定管板上
的螺栓拧下，将活动端的密封填料或盖板，以及冷却
水管卸下来（如有发动机系统的部件妨碍撤下管组，
这些部件都应拆除）。最后用适当的起吊装置将管组

２． 固定式空冷器 ２．１ 概 述
固定式空冷器“Ｂｌｏｃｋ Ｃｏｏｌｅｒ”直接安装在发动 机的风道中，正如第 １ 部分所述，空冷器的侧板和管 板用螺栓直接固定在风道中相应的位置上。
“固定式空冷器”有两种结构形式，即单回路和 双回路。回路数即指流过空冷器冷却水的循环水回 路数。
双回路空冷器有两个互不相通的循环水回路， 各水路有其不同的目的。例如：高温水回路用于发动 机缸套冷却，低温水回路用于油的预热。
频繁改变水的流速不利于在空冷器内壁形成保护
膜，而保护膜对于防腐蚀是至关重要的。如果水流速太
小，容易产生沉积物； 如果水流速太大，又容易产生侵
蚀。管路的节流或进水口的位置不当，都容易产生易造
成腐蚀的富氧水。为了在部分负载的情况下也保持均衡
的水流量、流速，就必须安装控制装置。
４．３ 冷却水流速的控制
现已证明，下图所示的旁通控制装置能满足控制水 流速、流量的要求。旁通装置可以这样设置：即，空冷 器的出水端与冷却水泵进水端旁通，由阀门及控制装置 来调节空冷器进水的冷热度和流量，以保证增压空气出 口温度的衡定。这样就能在各种负荷下使冷却水流量、 流速和空冷器出气温度保持在推荐的范围内变动。
多级空冷器由多组管组组成，这些管组都安装 进同一个箱体内。
多级空冷器的级数是指串联在一个水回路的管 组数，故级数不一定与回路数相同。
３．２ 空冷器的安装和拆卸
在安装空冷器前，应先拆下进、出气侧和水管连
接法兰上的罩盖物 ；并用松香水洗去用于保护气侧
和水侧密封面的保护物。
空冷器既可以直接安装在发动机上，也可以悬

“可拆式管组空冷器（Ｒ ｅ ｍ ｏ ｖ ａ ｂ ｌ ｅ Ｓ ｔ ａ ｃ ｋ Ｃｏｏｌｅｒ）”即可拆卸的管组连同其外壳一起安装到发 动机的风道中。正如第１ 部分所述，用螺栓将空冷器 的箱体固定在风道中，再把管组慢慢滑进箱体。用螺 栓将管组上大管板（固定管板）固定在箱体上并加装 垫片以气密。活动管板是通过一个Ｏ 型橡胶圈和一 个长方形密封法兰而形成密封，也可以使用平端盖。

５． 保护膜
确保形成结实、耐久保护膜的方法。 铜及铜合金所固有的耐腐蚀性能就在于：它们
能够形成难以溶解的自然保护膜。 千万不要把污水用于未形成良好保护膜的新空
冷器中，因为冷却管内表面的沉积附着物，不利于形 成上述保护膜。

空冷器传热元件有：椭圆管方片、圆管圆片及圆 管方片等几种结构形式。管与片的连接方式通常有： 钎焊式、整体轧制式和机械胀接式。
冷却管由胀管器将其两端紧紧地胀接到管板上。 侧板作为空冷器的一部分，与管板用螺栓连接 紧固。 端盖（即进出水端盖和回流水端盖），作为循环 水室，按设计的水流程数设置隔水筋。端盖上装有旋 塞用于空冷器的放气和排水。端盖与管板间装有密 封垫并用螺栓将其紧固。 端盖、管板和冷却管的材质是根据冷却水质和 设计水流速来选择的。 增压空冷器安装在涡轮增压器和柴油机进气总 管之间的风道中。其安装形式有两种： １、空冷器可直接装在风道中（固定式空冷器）， 这时把空冷器的侧板和管板直接用螺栓安装到风道 上，形成风道的一部分。 ２、空冷器先装进箱体，然后把箱体用螺栓安装 到风道上（可拆式空冷器）。用此法安装，在拆卸维 修空冷器时可以不拆卸风道。
