拖车发电机组是将涡轮、汽轮机、柴油机或其他动力机器驱动的其他形式的能量转换成电能的机械设备,由水、气流、燃料燃烧或原子核裂变产生的能量转换成机械能,由发电机转换成电能。
Trailer generator set is a mechanical equipment that converts other forms of energy driven by turbine, steam turbine, diesel engine or other power machines into electrical energy. The energy generated by water, air flow, fuel combustion or nuclear fission is converted into mechanical energy and converted into electrical energy by generator.
拖车发电机组的柴油发动机是动力的输出部分,以柴油为燃料,燃烧压缩在汽缸中形成的高温高压空气喷射的雾柴油,使其膨胀,将热量转化为机械能。通过进气、压缩、工作、排气四个过程,完成工作循环,也称为四冲程发动机。为了降低零件温度,主体里布满水道、泵称为水冷装置低功耗引擎也使用空气冷却引擎,称为风冷机。
The diesel engine of the trailer generator set is the output part of the power. With diesel as the fuel, it burns and compresses the mist diesel injected by the high-temperature and high-pressure air formed in the cylinder to expand and convert the heat into mechanical energy. Through the four processes of intake, compression, operation and exhaust, the working cycle is completed, which is also called four stroke engine. In order to reduce the temperature of parts, the main body is full of waterways and pumps, which are called water cooling devices. Low power engines also use air cooling engines, which are called air coolers.
目前我国电力紧张问题越来越突出,同时对环境保护的要求也越来越高。作为电网的备用电源,有安静扬声器的静音房车发电机噪音小,被大量使用。带静音扬声器的静音房车发电机可以达到30dB的噪音量,但我国产品与国外相比存在较大差异,针对柴油发电机的静音扬声器综合利用多种降噪技术,将噪音从108dB降低到75dB以下,提高了降噪效果。为了有效地控制噪音,首先分析设备噪音的发生和分布,有针对性地使用噪音控制技术。根据燃烧室拖车发电机组的工作原理,其噪音的产生非常复杂。在发生原因和部位,拖车发电机组的噪音可能包括以下部分:
At present, the problem of power shortage in China is becoming more and more prominent, and the requirements for environmental protection are becoming higher and higher. As the backup power supply of the power grid, the silent RV generator with quiet speakers has low noise and is widely used. The mute RV generator with mute speaker can achieve 30dB noise, but there are great differences between Chinese products and foreign products. For the mute speaker of diesel generator, a variety of noise reduction technologies are comprehensively used to reduce the noise from 108db to below 75db, which improves the noise reduction effect. In order to effectively control noise, first analyze the occurrence and distribution of equipment noise, and use noise control technology. According to the working principle of combustion chamber Trailer generator set, its noise generation is very complex. The noise of the trailer generator set may include the following parts in the cause and location:
1)拖车发电机组内燃机排气噪音。也就是说,内燃机排气通道噪音、排气噪音是高温、高速脉动气流噪音,是噪音的能量、成分多的部分,远远高于进气噪音和气体辐射的机械噪音,是总噪声的主要部分,也是噪声控制的。它的基本频率是内燃机的点火频率。
沼气发电机组
1) Exhaust noise of internal combustion engine of trailer generator set. In other words, the exhaust channel noise and exhaust noise of internal combustion engine are high-temperature and high-speed pulsating air flow noise, which is the part with many energy and components of the noise, which is much higher than the intake noise and the mechanical noise radiated by gas. They are the main part of the total noise and the focus of noise control. Its basic frequency is the ignition frequency of the internal combustion engine.
2)拖车发电机组进气噪音。箱子进气口噪音、进气噪音主要有静音拖车发电机机器噪音、发电机噪音、气流噪音等。由于空气吸入是被动的流入,并且远离主噪音源,所以噪音水平相对于其他位置较低,因此所需的噪音减少量较小。
2) Intake noise of trailer generator set. The noise at the air inlet and air inlet of the box mainly include silent Trailer generator machine noise, generator noise, air flow noise, etc. Since the air intake is a passive inflow and is far away from the main noise source, the noise level is low relative to other locations, so the required noise reduction is small.
3)拖车发电机组排气噪音。也就是说是箱子排放口的噪音。排气噪音的主要成分是排气噪音、气流噪音、风扇噪音、机器噪音、内燃机燃烧噪音等。噪音源多,噪音等级高,静音房车发电机强的排气冷却会增加噪音的外向,因此噪音控制比较困难。
3) Exhaust noise of trailer generator set. That is, the noise from the box outlet. The main components of exhaust noise are exhaust noise, air flow noise, fan noise, machine noise, combustion noise of internal combustion engine, etc. There are many noise sources and the noise level is high. The quiet RV generator has strong exhaust cooling, which will increase the export of noise, so it is difficult to control noise.
