燃氣發電機作為一種高效的動力設備，在備用電源、移動供電等場景中應用廣泛，其組成結構精密且各部分協同工作，確保穩定輸出電能。其核心組成主要包括發動機、電機、控制器三大模塊，采用四沖程工作原理，按冷卻方式可分為水冷式與風冷式兩類，不同冷卻方式適用于不同的運行環境，水冷式散熱更穩定，適合長時間高負荷運轉，風冷式結構更緊湊，便于移動場景使用。

　　As an efficient power equipment, gas generators are widely used in backup power sources, mobile power supply and other scenarios. Their precise composition and coordinated operation of various parts ensure stable output of electrical energy. Its core components mainly include three modules: engine, motor, and controller. It adopts a four stroke working principle and can be divided into two types according to cooling methods: water-cooled and air-cooled. Different cooling methods are suitable for different operating environments. Water cooled cooling has more stable heat dissipation and is suitable for long-term high load operation. Air cooled structure is more compact and easy to use in mobile scenarios.

　　從整體構成來看，燃氣發電機組屬于內燃發電機組的一種，除核心的三大模塊外，還包含柴油機、交流同步發電機、控制箱（屏）、聯軸器和公共底座等部件，部分機組還配備專用的燃油箱、水箱和消聲器。其中，消聲器能有效降低運行時的噪音，水箱則為水冷系統提供循環保障，這些部件共同構成了完整的發電系統。

　　From the overall composition, gas generator sets belong to a type of internal combustion generator set. In addition to the three core modules, they also include components such as diesel engines, AC synchronous generators, control boxes (screens), couplings, and common bases. Some units are also equipped with dedicated fuel tanks, water tanks, and mufflers. Among them, the muffler can effectively reduce the noise during operation, and the water tank provides circulation guarantee for the water cooling system. These components together constitute a complete power generation system.

　　每臺燃氣發電機組都設有三個主要標牌，用于標識關鍵參數。進口機組的標牌常采用英文標注，盡管不同制造商的出廠編制規則存在差異，但標牌需清晰標明發動機的形式、額定輸出功率、額定轉速；發電機的額定功率、額定轉速、額定電壓、額定電流、絕緣等級、功率因數及接線方式；以及發電機組的持續功率、額定電壓、額定電流、轉速、制造商和出廠日期等核心信息，這些數據是用戶正確使用和維護機組的重要依據。

　　Each gas-fired generator set is equipped with three main signs to identify key parameters. The label of imported units is often marked in English. Although there are differences in the factory preparation rules of different manufacturers, the label should clearly indicate the form, rated output power, and rated speed of the engine; The rated power, rated speed, rated voltage, rated current, insulation level, power factor, and wiring method of the generator; And the core information of the generator set, such as continuous power, rated voltage, rated current, speed, manufacturer, and date of manufacture, are important basis for users to correctly use and maintain the unit.

　　在機組的組裝形式上，一般中小功率的成套機組多采用一體化設計，即通過公共底座將柴油機、交流同步發電機和控制屏等主要部件整合安裝，形成一個緊湊的整體，這種設計便于整體搬運和快速安裝。而大功率機組由于體積和重量較大，除柴油機和發電機安裝在型鋼焊接的公共底座上外，控制屏、燃油箱和水箱等設備需單獨設計，以方便運輸、移動和現場安裝調試。

　　In terms of the assembly form of the unit, generally small and medium-sized complete sets of units adopt integrated design, that is, the main components such as diesel engine, AC synchronous generator, and control panel are integrated and installed through a common base to form a compact whole. This design is convenient for overall handling and fast installation. Due to their large size and weight, high-power units require separate design for equipment such as control panels, fuel tanks, and water tanks, in addition to diesel engines and generators installed on a common base welded with steel sections, to facilitate transportation, movement, and on-site installation and commissioning.

　　在動力傳遞方面，柴油機的飛輪殼與發電機前端蓋軸通過凸肩定位直接連接，形成穩固的一體結構，并采用圓柱形彈性聯軸器由飛輪直接驅動發電機旋轉。這種連接方式通過螺釘緊密固定，能確保柴油機曲軸與發電機轉子的同心度控制在規定范圍內，減少運行時的振動和磨損，保障機組長期穩定運行。

　　In terms of power transmission, the flywheel housing of the diesel engine is directly connected to the front cover shaft of the generator through a shoulder positioning, forming a stable integrated structure, and a cylindrical elastic coupling is used to directly drive the generator to rotate by the flywheel. This connection method is tightly fixed by screws, ensuring that the concentricity between the diesel engine crankshaft and the generator rotor is controlled within the specified range, reducing vibration and wear during operation, and ensuring long-term stable operation of the unit.

　　發動機作為燃氣發電機的動力源，負責將燃氣的化學能轉化為機械能，其四沖程工作過程（吸氣、壓縮、做功、排氣）精準配合，為整個機組提供持續動力。電機則將機械能轉化為電能，交流同步發電機能保證輸出電流的穩定性，滿足不同用電設備的需求。控制器作為機組的 “大腦”，實時監控運行參數，如轉速、溫度、電壓等，實現自動啟停、故障保護等功能，確保機組在安全范圍內高效運轉。這些部件的協同作用，使得燃氣發電機能夠適應多樣化的供電需求，成為可靠的動力設備。

　　The engine, as the power source of the gas generator, is responsible for converting the chemical energy of the gas into mechanical energy. Its four stroke working process (suction, compression, work, exhaust) is precisely coordinated to provide continuous power for the entire unit. Electric motors convert mechanical energy into electrical energy, while AC synchronous generators ensure the stability of output current and meet the needs of different electrical equipment. As the "brain" of the unit, the controller monitors operating parameters in real time, such as speed, temperature, voltage, etc., to achieve automatic start stop, fault protection and other functions, ensuring that the unit operates efficiently within a safe range. The synergistic effect of these components enables gas generators to adapt to diverse power supply needs and become reliable power equipment.
