第三章 柴油机的安装与连接
1 柴油机的安装
1.1. 柴油机的安装方式可根据用户的安装需求,提供两点或四点支撑的方式。柴油机、发电
机、散热器共同安装在同一个公共底架上,一般采用弹性安装方式,其中柴油机安装所
用的减震器为用户可选件,采用合适的减震器能有效地降低柴油机、发电机工作时的振
动影响。
1.2. 发电机组安装的基础一定要坚实可靠,支撑面应水平平整,机组安装时一定要找平。机
组公共底架与基础之间应采取一定的减震措施,保证机组有好的隔振效果,以降低和减
轻机组工作时对周围其它设备和建筑物的影响。
1.3. 当机组在机房布置时,一定要注意柴油机及机组的操作、使用、维护管理和维修的空间
位置。
2 动力输出接口的连接
1 当柴油机与双轴承结构的发电机连接时,可采用柴油机飞轮壳与发电机止口法兰定位的
方式,如不采用止口定位的方式,则应在连接时校正柴油机与发电机轴线的同轴度,同
轴度误差应不大于Φ0.2mm。
2 柴油机的输出接口采用国际通用的标准SAE接口。柴油机与发电机连接时,发电机的法
兰接口与柴油机飞轮壳止口配合,发电机的弹性联轴器片与飞轮凹止口配合。弹性联轴
器片与飞轮的安装建议采用8.8级及以上螺栓,采用硬垫圈,不要采用弹簧垫圈。
3 冷却系统安装
1 散热器安装时,紧固牢靠。当安装在移动电站时,与车架的连接必须采用减振垫,采用
减振垫的目的是为了隔离和吸收来自车架的部份振动和冲击。
2 为使冷却效果达到最佳,建议散热器安装时,风扇前端面至散热器芯子的距离应至少大
于50 mm;护风罩与风扇叶尖的径向间隙均匀,且不应超过风扇直径的2.5 %,或者15 mm
~20 mm;风扇伸入护风罩的轴向位置,有1/3风扇投影宽度在护风圈内.。
3 机房使用时,应有足够的通风面积,应保证散热器热风的顺畅排出。
4 当柴油机在低于0℃环境条件使用时,应使用防冻冷却液。
4 电器仪表控制系统的安装与连接
1 柴油机电器仪表控制系统均为24V直流电源,电起动;发电机为整体式交流发电机;采
用负极搭铁单线制。
2 蓄电池由用户自配,建议蓄电池容量不小于150A.h。起动电缆线截面积应大于50mm²,
21
充电电源线截面积大于4mm²,其余连接线为2.5mm²。
3 柴油机出厂时一般不带仪表系统,仪表系统作为用户选用件由用户自行选购和安装。部
分带仪表的机型在出厂时,仪表箱线束已经连接好,无须用户接线。如需更换线束,只
需按线束上的号码一一对应的接入仪表箱和柴油机上对应的编号接口即可。
4 仪表应安装在振动较小的地方,避开排气系统直接传热或近距离热辐射,排气管靠近仪
表部位应用隔热材料包裹,以免温度过高引起仪表失灵。在安装过程中应避免对仪表箱
体的强烈冲击。
5 电器系统的接线必须正确,正负极绝不可接错,否则将会损坏电器设备,导致柴油机不
能运行的严重后果。
6 带电子调速器的控制系统的安装、使用和接线方法参照《电子调速器说明书》。

3 Engine Installation and Connection
3.1 Installation
1.Engine installation varies from the requirement of users. There are 2-point engine support and
4-point engine support to select. Engine, generator and radiator are mounted on a same base with
elastic mounting method. Vibration isolation for engine mounting is for option. Proper isolator
provides effective reduction of vibration arising from engine and generator operation.
2.The ground for a generating set should be solid, reliable and flat. Vibration isolation should be
employed between the ground and the base to reduce and lighten vibration effect on surrounding
equipment and buildings when the generating set operates. .
3.Enough space for operation, maintenance and repair of generating set should be maintained
when making its layout.
3.2 PTO connection
1. When connecting an engine to dual-bearing structured generator, use the flange of a generator
and the flange bore of a flywheel housing for setting, otherwise the coaxial of an engine and a
generator should be controlled within Φ0.2mm.
2. SEA connection is adopted for PTO. When connecting an engine to a generator, match the
generator flange to the stop face of the engine flywheel housing, and the flexible coupling plate of
the generator to the recess stop face of the flywheel. It is recommended to use the bolt of Grade
8.8, hard washer instead of spring washer for connection.
3.3 Cooling system installation
1. Radiator should be secured. Cushion should b used between the radiator and the chassis to
isolate and absorb part of vibration and impact from the chassis.
2. For an optimal cooling effect, it is recommended to keep at least 50 mm between the front end
face of a fan and a radiator element, even clearance of less than 2.5 % of the fan diameter or 15-20
mm between the fan shroud and the tips of the fan, and one-third projected width of the fan within
the fan shroud.
3. When the engine is chambered, enough space should be maintained to ensure a good discharge of
hot wind from the radiator.
4. Coolant with anti-freezing additive should be used when an engine is operated under 0℃.
23
3.4 Installation and connection of instrument and control system
1. All instrument and control system of the engine are supplied with 24V CD electric power and an
engine is started by an electric motor. An alternator is used with single negative grounding
system.
2. Battery is not provided with engine. It is suggested to use a battery with capacity not less than
150A•h. The section area of starting cable should be over 50 mm², electric charging cable over 4
mm² and rest wires over 2.5 mm².
3. Instrument is for option and not usually provided with an engine. Some engines equipped with
an instrument box are provided with connected harness and no more wire connection is required.
When changing harness, it only requires connecting the ends of harness to the corresponding
terminals of instrument box and engine according to their numbers.
4. Instrument should be installed in the place where is subject to less vibration, and away from
direct heat conduction or radiation of exhaust system. It is required to shield exhaust manifold
with heat isolation material if the instrument is nearby to avoid its malfunction due to high
temperature. It is also required to keep an instrument box from sever impact during installation.
5. It is required to make a correct wire connection of an electrical system. Never make any wrong
connection with positive to negative, which will damage electrical equipment and lead to failure in
engine operation.
6. For the installation, usage and wire connection of the control system for an electronic governor,
refer to Operation Manual for Electronic Governor.
