        拖車(chē)發(fā)電機組是什么原理構成的?

        拖車(chē)發(fā)電機組是將渦輪、汽輪機、柴油機或其他動(dòng)力機器驅動(dòng)的其他形式的能量轉換成電能的機械設備,由水、氣流、燃料燃燒或原子核裂變產(chǎn)生的能量轉換成機械能,由發(fā)電機轉換成電能。
        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.
        拖車(chē)發(fā)電機組的柴油發(fā)動(dòng)機是動(dòng)力的輸出部分,以柴油為燃料,燃燒壓縮在汽缸中形成的高溫高壓空氣噴射的霧柴油,使其膨脹,將熱量轉化為機械能。通過(guò)進(jìn)氣、壓縮、工作、排氣四個(gè)過(guò)程,完成工作循環(huán),也稱(chēng)為四沖程發(fā)動(dòng)機。為了降低零件溫度,主體里布滿(mǎn)水道、泵稱(chēng)為水冷裝置低功耗引擎也使用空氣冷卻引擎,稱(chēng)為風(fēng)冷機。
        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.
        目前我國電力緊張問(wèn)題越來(lái)越突出,同時(shí)對環(huán)境保護的要求也越來(lái)越高。作為電網(wǎng)的備用電源,有安靜揚聲器的靜音房車(chē)發(fā)電機噪音小,被大量使用。帶靜音揚聲器的靜音房車(chē)發(fā)電機可以達到30dB的噪音量,但我國產(chǎn)品與國外相比存在較大差異,針對柴油發(fā)電機的靜音揚聲器綜合利用多種降噪技術(shù),將噪音從108dB降低到75dB以下,提高了降噪效果。為了有效地控制噪音,首先分析設備噪音的發(fā)生和分布,有針對性地使用噪音控制技術(shù)。根據燃燒室拖車(chē)發(fā)電機組的工作原理,其噪音的產(chǎn)生非常復雜。在發(fā)生原因和部位,拖車(chē)發(fā)電機組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)拖車(chē)發(fā)電機組內燃機排氣噪音。也就是說(shuō),內燃機排氣通道噪音、排氣噪音是高溫、高速脈動(dòng)氣流噪音,是噪音的能量、成分多的部分,遠遠高于進(jìn)氣噪音和氣體輻射的機械噪音,是總噪聲的主要部分,也是噪聲控制的。它的基本頻率是內燃機的點(diǎn)火頻率。
        沼氣發(fā)電機組
        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)拖車(chē)發(fā)電機組進(jìn)氣噪音。箱子進(jìn)氣口噪音、進(jìn)氣噪音主要有靜音拖車(chē)發(fā)電機機器噪音、發(fā)電機噪音、氣流噪音等。由于空氣吸入是被動(dòng)的流入,并且遠離主噪音源,所以噪音水平相對于其他位置較低,因此所需的噪音減少量較小。
        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)拖車(chē)發(fā)電機組排氣噪音。也就是說(shuō)是箱子排放口的噪音。排氣噪音的主要成分是排氣噪音、氣流噪音、風(fēng)扇噪音、機器噪音、內燃機燃燒噪音等。噪音源多,噪音等級高,靜音房車(chē)發(fā)電機強的排氣冷卻會(huì )增加噪音的外向,因此噪音控制比較困難。
        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.
