热力学和发动机燃烧实验室机油和冷却水冷却系统指标货物需求一览表The following system has the following main elements:系统主要包含下面主要部分 Oil conditioning circuit发动机机油温度调节冷却回路 Coolant conditioning circuit 冷却水调节回路 Dry sump scavenge tank 干式扫气油箱 EGR cooling circuit废气再循环冷却调节回路The cooling system allows the temperature of both coolant and oil to be conditioned by either heating or cooling the circulating fluids. Oil supply pressure can also be controlled. This is achieved by having a bleed valve installed in the supply pipework. These valves is then electro-pneumatically actuated to allow transient pressure variation.冷却系统可以通过加热或冷却循环介质来调节冷却液和机油的温度。供油压力也可以 控制。这是通过在供应管道上安装放气阀来实现的。这些阀门是由气动电磁阀驱动， 以允许瞬态压力的变化。Typically control temperatures of between 80 and 100 are possible, however as with all products, flexibility is inherent in the design to allow an amount of adaptation, should requirements change. The temperature is controlled using PID channels provided in the control system. The temperature of the oil and water/glycol can be set constant, or varied during a test as necessary. The system can also be used for conditioning of the engine prior to testing. The 'EVENTS' feature in software control system can be set to optimize the warm up time for the engine.常规的温度控制在80至U 100之间。通过软件系统PID通道来控制温度。机油和水/ 乙二醇的温度可以设置为恒定值，也可以在测试过程中根据需要改变。该系统也可以 用于发动机做实验前的准备条件设置。这些设置可作为发动机暖机的优化控制。Extent of supply, for the conditioning units 提供范围，冷却控制单元 Heaters加热器 Heat exchanger for cooling modes 冷却模式的热交换器 Control box 控制箱 Flexible hoses to connect to the engine circuits用于连接发动机循环的柔性连接管 Circulating pumps and Sump, aeration tanks 循环泵和膨胀水箱 Level, pressure and temperature monitoring 液位、压力和温度监控 3way control valve for cooling circuits 冷却循环 3 通控制阀 Pressure regulation valve (oil circuit only) 压力调节阀 Twin scavenge pumps 双扫气泵 EGR glycol circuit and control valve EGR 乙二醇循环和控制阀 EGR cooler and exhaust gas control valve to be supplied by others EGR 冷却I器和排气控 制阀System specifications 系统技术参数OilMax Oil Flow Rate37.5 l/minTypical Oil Supply Pressure4 bar gaugeSuggested Oil Delivery Temperature80 -100Maximum Heat Rejection in Oil7kW (A28 at Max Flow)Heating power3kWCoolant1Max Coolant Flow Rate100 l/minTypical Coolant Supply Pressure1 bar gaugeSuggested Coolant Delivery Temperature80 -100Maximum Heat Rejection in Coolant31kW(A14at MaxFIow)Heating capability3kW机油冷却回路最大流量37.5 l/min压力4bar表压建议机油输送温度80-100 度在油中最大排热量7kW加热功率3kW冷却液回路最大冷却水流量1001/min冷却液压力lbar表压建议冷却液输送温度80-100 度在冷却液中最大排热量31kW加热能力3kW
