At present, the structure of the generator set sold on the market is mainly divided into several main parts, such as diesel engine, generator, base oil tank, water tank and damping pad. The main parts are divided into base, control system and fuel supply system. The following is a detailed introduction to the characteristics of the main system structure of gas generator set.

1、底座：1. Base:

底座有两种形式构成，一种是底座分开架式，一种是底座油箱式，底座是由槽钢采用钢板经剪折后焊接成型的，底座上设有柴油发电机支架、发电机支架、水箱支架，底座油箱式的还设有加油口，油位计、进油口和出油口。150KW以下的柴油发电机组全部采用钢板制作，钢制底座全部经过酸洗磷化处理然后进行喷塑，底座的边角全部采用无伤手处理。

The base is composed of two forms: one is the separate frame type of the base, and the other is the oil tank type of the base. The base is welded by the channel steel plate after being cut and folded. The base is equipped with diesel generator support, generator support and water tank support. The oil tank type of the base is also equipped with oil filler, oil level gauge, oil inlet and oil outlet. All diesel generator sets below 150KW are made of steel plate, the steel base is treated with acid pickling and phosphating, and then sprayed with plastic, and the edges and corners of the base are treated without hand injury.

2、控制系统：2. Control system:

发电机组的控制系统主要由控制器、继电器、熔断器、空气断路器、功能仪表、状态指示灯、无刷电机、电子调速执行器以及电调板等零件组成，柴油发电机组的控制系统的作用就像人类的大脑一样，主要用于控制柴油电机组的运行，显示机组的运行情况，调整发电机输出的电源的质量，对异常情况进行报警处理等。控制系统主要起到了控制和保护柴油发电机组的作用，保护内容有高水温、低油压、超速、电瓶电压等，在出现意外的时候能够有效地保护发电机组不受损伤以及机组操作人员的人身安全。

The control system of the generator set is mainly composed of controller, relay, fuse, air circuit breaker, functional instrument, status indicator, brushless motor, electronic speed regulating actuator, electric regulating board and other parts. The control system of the diesel generator set is like the human brain, which is mainly used to control the operation of the diesel generator set and display the operation of the unit, Adjust the quality of the power supply output by the generator, alarm and deal with abnormal conditions, etc. The control system mainly plays the role of controlling and protecting the diesel generator set. The protection contents include high water temperature, low oil pressure, overspeed, battery voltage, etc. in case of accident, it can effectively protect the diesel generator set from damage and the personal safety of the unit operator.

3、燃油供给系统：3. Fuel supply system:

发电机组的燃油供给系统有两种，分别是机械式和电子式，机械式燃油供给系统采用机械式原理对燃油系统进行控制，当发电机组停机时会及时切断供油，保证燃油不会回流，保证燃油管道内不会形成真空，保证再次启动柴油发电机组时候不需要手动预供油的工作，价格比较便宜。

There are two types of fuel supply systems for the generator set, mechanical and electronic. The mechanical fuel supply system uses the mechanical principle to control the fuel system. When the generator set is shut down, it will cut off the fuel supply in time to ensure that the fuel will not return, that there will be no vacuum in the fuel pipe, and that there is no need for manual pre fuel supply when starting the diesel generator set again, The price is relatively cheap.

电子式燃油供给系统是按照电路接好控制装置，对燃油系统进行控制，电子式燃油供给系统是根据写好的程序进行判断和执行操作的，相比机械式燃油供给系统功能更多、操作简单，安全。

The electronic fuel supply system is connected with the control device according to the circuit to control the fuel system. The electronic fuel supply system judges and operates according to the written program. Compared with the mechanical fuel supply system, it has more functions, simple operation and safety.

根据功能的不同价格也有差异，功能强的电子式燃油供给系统价格会略微高于机械式燃油供给系统。

The price varies according to different functions. The price of the electronic fuel supply system with strong functions will be slightly higher than that of the mechanical fuel supply system.
