1、不同气候环境对柴油发电机组运行的影响：The impact of different climates on the diesel generators.

雨水,灰尘和风沙,海边的盐水和雾气,空气中含有腐蚀气体，如二氧化硫。

Such as rain,dust and sand, salt water and fog at the seaside, and the air contains corrosive gases such as sulfur dioxide.

2、柴油发电机组的组成：Composition of diesel generator.

柴油发动机、发电机、控制器。其他组成部分：底座、底座油箱、散热器、水箱、反冲垫、防音箱、消音器、静音箱等部件组成。

Diesel engine, alternator, controller. Other components like base, base fuel tank, radiator, water tank, recoil pad, anti-speaker, muffler, silencer and other components.

3、噪音等级介绍：Noise level introduction.

30～40分贝是较理想的安静环境。超过50分贝就会影响睡眠和休息。70分贝以上会干扰谈话，影响工作效率。长期生活在90分贝以上的噪声环境，会严重影响听力和引起神经衰弱、头疼、血压升高等疾病。如果突然暴露在高达150分贝的噪声环境中，听觉器官会发生急剧外伤，引起鼓膜破裂出血，双耳完全失去听力。为了保护听力，应控制噪声不超过90分贝;为了保证工作和学习，应控制噪声不超过70分贝为了保证休息和睡眠，应控制噪声不超过50分贝。

30 to 40 decibels is an ideal quiet environment.More than 50 decibels will affect sleep and rest.More than 70 decibels will interfere with the conversation and affect work efficiency. Long-term living in a noise environment above 90 decibels will seriously affect hearing and cause neurasthenia, headaches, blood pressure and other diseases. If you are suddenly exposed to a noise environment of up to 150 decibels,the auditory organs will suffer acute trauma,causing tympanic membrane rupture and bleeding, and complete loss of hearing in both ears. In order to protect hearing, the noise should not exceed 90 decibels.In order to ensure work and study, the noise should not exceed 70 decibels. In order to ensure rest and sleep, the noise should be controlled not to exceed 50 decibels.

4、柴油发电机组并联运行的目的.The purpose of parallel operation of diesel generator ;

扩大供电容量Expand power supply capacity.

提高供电可靠性，实现不间断供电。Improve the reliability of power supply and realize uninterrupted power supply.

5、燃油消耗计算：Fuel consumption calculation.

燃油消耗量(L/h) = 柴油机额定功率（kw）X 燃油消耗率（g/kwh) / 1000 / 0.84（柴油0#的密度取值为0.84kg/L）

Fuel consumption (L/h) = diesel engine rated power (kw) X fuel consumption rate (g/kwh) / 1000 / 0.84 (the density of diesel 0# is 0.84kg/L)

6、柴油发电机组长时间过载会怎样.Generator overloaded for a long time.

机组运行时通常不能过载，但是可以承受短期的过载。如果机组过载时间过长（超过额定功率）可能会发生一些状况。

包括：冷却系统过热、发电机绕组过热、润滑油浓度分解造成油压过低、机组寿命减短。

The unit usually cannot be overloaded during operation, but it can withstand short-term overload. If it is overloaded for too long (exceeding the rated power), some conditions may occur.

Including overheating of the cooling system and generator windings, low oil pressure caused by decomposition of lubricating oil concentration, and shortened unit life.

7、柴油机温渡过高时，立即加冷却水是否可行？Can add cooling water immediately when the diesel engine temperature is too high?

绝对不可以，要等到发动机自然冷却至常温方可加入冷却水。若在柴油机缺水过热的情况下溘然加冷却水，会使缸盖、缸套、缸体等因冷热剧烈变化而产生裂纹，对发动机造成严重的损伤。

Absolutely not. The cooling water can only be added until the engine has cooled down to room temperature.If the cooling water is suddenly added when the diesel engine is short of water and overheating, it will cause cracks in the cylinder head, cylinder liner, cylinder block. due to the drastic changes in cold and heat, causing serious damage to the engine.

8、柴油发电机组的噪声来源有哪些？What are the noise sources of diesel generator sets?

进气噪声、排气噪声和冷却风扇噪声

燃烧室工作燃烧噪声、发动机零部件摩擦的机械噪声

转子在电磁场中高速旋转产生的噪声

Intake noise, exhaust noise and cooling fan noise.

The combustion chamber working noise, the mechanical noise of the friction of engine parts.

The noise generated by the high-speed rotation of the rotor in the electromagnetic field.

9、冬季柴油发电机组启动技巧。Starting Skills of Diesel Generators in Winter

预热：冷却系统可加热水，用热源对油底壳进行加热。

提高气密性：可将喷油器拆下，每缸内加入30～40ml机油，以增强汽缸的密封性能，提高压缩时的压力。

盘车：启动前先摇转曲轴，使其运转轻松后再启动。

Preheating.The cooling system can heat water and heat the oil pan with a heat source.

Improve air tightness.The injector can be removed, and 30-40ml of oil is added to each cylinder to enhance the sealing performance of the cylinder and increase the pressure during compression.

Cranking.Before starting, crank the crankshaft to make it run easily before starting.

10、调速器的作用是什么？What is the function of the governor?

调速器要能根据外界负荷的变化，灵敏地调节供油量，以保持转速的稳定。它必须具备两个基本部分：感应元件与执行机构。

The speed governor must be able to adjust the fuel supply sensitively according to the changes in the external load to maintain the stability of the speed. It must have two basic parts,sensing elements and actuators.
