燃?xì)獍l(fā)電機(jī)組由燃?xì)獍l(fā)動(dòng)機(jī)、發(fā)電機(jī)、控制柜等部件組成。燃?xì)獍l(fā)動(dòng)機(jī)和發(fā)電機(jī)安裝在同一個(gè)鋼制底盤上。那么你知道燃?xì)獍l(fā)電機(jī)組出現(xiàn)空氣動(dòng)力噪聲表現(xiàn)是什么嗎？
The gas generator set is composed of gas engine, generator, control cabinet and other components. The gas engine and generator are installed on the same steel chassis. So do you know the performance of aerodynamic noise in gas generator set?
燃?xì)獍l(fā)電機(jī)組噪聲是由多種聲源組成的復(fù)雜聲源。按噪聲輻射方式可分為氣動(dòng)噪聲、表面輻射噪聲和電磁噪聲。根據(jù)產(chǎn)生的原因，康明斯燃?xì)獍l(fā)電機(jī)的表面輻射噪聲可分為燃燒噪聲和機(jī)械噪聲。其中，空氣動(dòng)力噪聲是主要噪聲源。
The noise of gas generator set is a complex sound source composed of many sound sources. According to the mode of noise radiation, it can be divided into aerodynamic noise, surface radiation noise and electromagnetic noise. According to the causes, the surface radiation noise of Cummins gas generator can be divided into combustion noise and mechanical noise. Among them, aerodynamic noise is the main noise source.
氣動(dòng)噪聲是由于氣體的非穩(wěn)態(tài)過程，即氣體的擾動(dòng)和氣體與物體的相互作用而引起的。空氣動(dòng)力噪聲直接輻射到大氣中，包括進(jìn)氣噪聲、排氣噪聲和冷卻風(fēng)扇噪聲。
Aerodynamic noise is caused by the unsteady process of gas, that is, the disturbance of gas and the interaction between gas and object. Aerodynamic noise radiates directly into the atmosphere, including intake noise, exhaust noise and cooling fan noise.
燃?xì)獍l(fā)電機(jī)組的燃燒噪聲和機(jī)械噪聲很難嚴(yán)格區(qū)分。通常，由氣缸內(nèi)燃燒形成的壓力波動(dòng)通過氣缸蓋、活塞、連桿、曲軸和機(jī)體而輻射的噪聲稱為燃燒噪聲。
It is difficult to strictly distinguish the combustion noise and mechanical noise of gas generator set. Generally, the noise radiated by the pressure fluctuation formed by combustion in the cylinder through the cylinder head, piston, connecting rod, crankshaft and body is called combustion noise.
活塞對(duì)缸套的沖擊以及運(yùn)動(dòng)部件的機(jī)械沖擊和振動(dòng)所產(chǎn)生的噪聲稱為機(jī)械噪聲。一般來說，燃?xì)鈾C(jī)的燃燒噪聲高于機(jī)械噪聲，而非直噴燃?xì)鈾C(jī)的機(jī)械噪聲高于燃燒噪聲。但低速運(yùn)行時(shí)燃燒噪聲高于機(jī)械噪聲，電磁噪聲是燃?xì)獍l(fā)電機(jī)組轉(zhuǎn)子在電磁場(chǎng)中高速旋轉(zhuǎn)產(chǎn)生的。
The noise generated by the impact of piston on cylinder liner and the mechanical impact and vibration of moving parts is called mechanical noise. Generally speaking, the combustion noise of gas engine is higher than the mechanical noise, while the mechanical noise of non direct injection gas engine is higher than the combustion noise. However, the combustion noise during low-speed operation is higher than the mechanical noise. The electromagnetic noise is caused by the high-speed rotation of the rotor of the gas generator set in the electromagnetic field.
發(fā)電機(jī)組的安裝和使用，請(qǐng)嚴(yán)格按照說明書的要求進(jìn)行。請(qǐng)先檢查潤(rùn)滑油（油）、冷卻液（水箱）、燃油（燃?xì)猓┯偷挠臀弧z查燃?xì)鈾C(jī)供油、潤(rùn)滑、冷卻等系統(tǒng)的管路和接頭是否有漏水、漏油現(xiàn)象，電路有無破皮等漏電隱患；地線等電路是否松動(dòng)；機(jī)組與基礎(chǔ)的連接是否牢固。
Please install and use the generator set in strict accordance with the requirements of the manual. Please check the oil level of lubricating oil (oil), coolant (water tank) and fuel (gas) oil first. Check whether the pipelines and joints of fuel supply, lubrication and cooling systems of gas engine have water leakage and oil leakage, and whether the circuit has potential leakage hazards such as skin damage; Whether the ground wire and other circuits are loose; Whether the connection between the unit and the foundation is firm.

打開電動(dòng)開關(guān)，按下啟動(dòng)按鈕或啟動(dòng)電鎖，按住按鈕3-5秒。如果啟動(dòng)不成功，請(qǐng)等待大約兩分鐘后再重試。若三啟動(dòng)不成功，停止啟動(dòng)，排除蓄電池電壓或油路等故障因素，再啟動(dòng)。嚴(yán)禁帶負(fù)載低速啟動(dòng)。
Turn on the electric switch, press the start button or start the electric lock, and press and hold the button for 3-5 seconds. If the startup is not successful, please wait about two minutes and try again. If the third start is unsuccessful, stop the start, eliminate the fault factors such as battery voltage or oil circuit, and then start. It is forbidden to start at low speed with load.
啟動(dòng)時(shí)，應(yīng)觀察油壓。如果油壓不顯示或很低，應(yīng)立即停機(jī)檢查。機(jī)組啟動(dòng)后，檢查控制箱模塊或儀表參數(shù)：油壓、水溫、電壓、頻率等。注意機(jī)組的連接和牢固性，是否有松動(dòng)和劇烈振動(dòng)。
When starting, observe the oil pressure. If the oil pressure does not show or is very low, stop the machine immediately for inspection. After the unit is started, check the control box module or instrument parameters: oil pressure, water temperature, voltage, frequency, etc. Pay attention to the connection and firmness of the unit, and whether there is looseness and violent vibration.
