190 發電機組配件種類繁多，對于確保發電機組的正常運行起著至關重要的作用。以下將詳細介紹 190 發電機組的常見配件。

　　There are various types of accessories for the 190 generator set, which play a crucial role in ensuring the normal operation of the generator set. The following will provide a detailed introduction to the common accessories of the 190 generator set.

　　發動機部分配件：

　　Engine components:

　　活塞：在發動機氣缸內上下運動，實現將燃料燃燒產生的熱能轉化為機械能。活塞通常由高強度鋁合金制成，具有良好的耐熱性和耐磨性。例如在 16V190 燃氣發動機中，活塞需要承受高溫高壓的工作環境，其質量和性能直接影響發動機的動力輸出和可靠性。

　　Piston: It moves up and down inside the engine cylinder to convert the heat energy generated by fuel combustion into mechanical energy. Pistons are usually made of high-strength aluminum alloy, which has good heat resistance and wear resistance. For example, in a 16V190 gas engine, the piston needs to withstand a high-temperature and high-pressure working environment, and its quality and performance directly affect the engine's power output and reliability.

　　連桿：連接活塞和曲軸，將活塞的往復運動轉化為曲軸的旋轉運動。連桿一般采用優質合金鋼制造，具有足夠的強度和剛度。在一些情況下，如焦化煤氣發電機組中，如果燃氣中雜質成分含量過高，可能會導致機油過早變質，引起連桿小頭襯套腐蝕，間隙過大，從而使連桿產生過大的沖擊力，降低連桿小頭的強度，甚至導致連桿斷裂。

　　Connecting rod: connects the piston and crankshaft, converting the reciprocating motion of the piston into the rotational motion of the crankshaft. Connecting rods are generally made of high-quality alloy steel, which has sufficient strength and stiffness. In some cases, such as in coking gas generator sets, if the impurity content in the gas is too high, it may cause premature deterioration of the engine oil, corrosion of the connecting rod small head bushing, excessive clearance, resulting in excessive impact force on the connecting rod, reducing the strength of the connecting rod small head, and even leading to connecting rod fracture.

　　曲軸：是發動機的核心部件之一，將連桿傳來的力轉化為旋轉力矩輸出。曲軸通常由高強度合金鋼鍛造而成，經過精密加工和熱處理，以確保其具有足夠的強度、硬度和韌性。

　　The crankshaft is one of the core components of the engine, which converts the force transmitted from the connecting rod into rotational torque output. The crankshaft is usually forged from high-strength alloy steel and undergoes precision machining and heat treatment to ensure sufficient strength, hardness, and toughness.

　　凸輪軸：控制發動機氣門的開啟和關閉時間。在 12V190 燃氣發電機組降排溫試驗中，通過采用不同的凸輪軸來摸索降低排溫的最佳配置。

　　Camshaft: controls the opening and closing time of engine valves. In the 12V190 gas generator set temperature reduction test, the optimal configuration for reducing exhaust temperature was explored by using different camshafts.

　　電氣部分配件：

　　Electrical components:

　　發電機：將發動機輸出的機械能轉化為電能。發電機的性能直接影響發電機組的輸出功率和穩定性。例如在 Z12V190 柴油發電機組油改氣現場應用中，對發電機部分進行了升級改造，改造后機組運行平穩，輸出功率 425kW。

　　Generator: Convert the mechanical energy output by the engine into electrical energy. The performance of the generator directly affects the output power and stability of the generator set. For example, in the on-site application of Z12V190 diesel generator unit oil to gas conversion, the generator part was upgraded and renovated. After the renovation, the unit operated smoothly with an output power of 425kW.

　　控制模塊：可編程邏輯控制器（PLC）是一種常用的控制模塊，用于操作自動發電機組系統。在 PLC 中，命令以圖像形式呈現，可被解釋為邏輯電路命令，稱為梯形圖。輸入信號通常是開關，輸出信號命令是負載。在 190 發電機組中，輸出信號可以是電機，類似于發電機，基于發電機的邏輯運行。

　　Control module: Programmable Logic Controller (PLC) is a commonly used control module for operating automatic generator systems. In PLC, commands are presented in graphical form and can be interpreted as logic circuit commands, known as ladder diagrams. The input signal is usually a switch, and the output signal command is a load. In a 190 generator set, the output signal can be a motor, similar to a generator, operating based on the logic of the generator.

　　冷卻系統配件：

　　Cooling system accessories:

　　水泵：在發動機冷卻系統中，水泵負責循環冷卻液，將發動機產生的熱量帶走。在 12V190 燃氣發電機組降排溫試驗中，采用大流量水泵來降低排溫。

　　Water pump: In the engine cooling system, the water pump is responsible for circulating the coolant and taking away the heat generated by the engine. In the temperature reduction test of the 12V190 gas generator set, a high flow water pump is used to reduce the exhaust temperature.

　　散熱器：通過散熱片和風扇將冷卻液中的熱量散發到空氣中，保持發動機在合適的工作溫度范圍內。散熱器的散熱性能直接影響發動機的可靠性和壽命。

　　Radiator: It dissipates heat from the coolant to the air through fins and fans, keeping the engine within the appropriate operating temperature range. The heat dissipation performance of the radiator directly affects the reliability and lifespan of the engine.

　　進氣和排氣系統配件：

　　Accessories for intake and exhaust systems:

　　進氣管：將空氣引入發動機氣缸。在 12V190 燃氣發電機組降排溫試驗中，采用切向進氣管來摸索降低排溫的最佳配置。

　　Intake pipe: It introduces air into the engine cylinder. In the 12V190 gas generator set temperature reduction test, a tangential intake pipe was used to explore the optimal configuration for reducing exhaust temperature.

　　排氣管：將發動機燃燒后的廢氣排出。排氣管的設計需要考慮廢氣的排放效率和降噪效果。

　　Exhaust pipe: It discharges the exhaust gas from the combustion of the engine. The design of exhaust pipes needs to consider the emission efficiency and noise reduction effect of exhaust gases.

　　燃油系統配件：

　　Fuel system accessories:

　　燃油泵：將燃油從油箱輸送到發動機。燃油泵的性能直接影響發動機的燃油供應穩定性和可靠性。

　　Fuel pump: delivers fuel from the fuel tank to the engine. The performance of the fuel pump directly affects the stability and reliability of the engine's fuel supply.

　　噴油嘴：將燃油霧化后噴入發動機氣缸，與空氣混合燃燒。噴油嘴的霧化效果直接影響發動機的燃燒效率和排放性能。

　　Fuel injector: atomizes fuel and sprays it into the engine cylinder, mixing it with air for combustion. The atomization effect of fuel injectors directly affects the combustion efficiency and emission performance of the engine.
