Engineering Machinery Parts Explained

Here are ten key engineering machinery components, their function, and examples from leading brands:

1. Hydraulic Pump (液压泵, Гидравлический насос): The heart of the hydraulic system, providing pressurized fluid to power cylinders and motors.
   Example: Sandvik DR580 drilling rig's hydraulic pump | Sandvik DR580钻机液压泵 | Гидравлический насос буровой установки Sandvik DR580

2. Water Pump (水泵, Водяной насос): Circulates coolant through the engine to prevent overheating.
   Example: Epiroc Boomer L2C drill rig's water pump | Epiroc Boomer L2C钻机的水泵 | Водяной насос буровой установки Epiroc Boomer L2C

3. Main Control Valve (主控阀, Главный управляющий клапан): Directs the flow of hydraulic fluid to various functions, such as boom and stick movements.
   Example: Atlas Copco SmartROC D65 drill rig's main control valve | Atlas Copco SmartROC D65钻机的主控阀 | Главный управляющий клапан буровой установки Atlas Copco SmartROC D65

4. Final Drive (终传动, Бортовой редуктор): Transmits power from the travel motor to the track, allowing the machine to move.
   Example: Sandvik LH517 loader's final drive | Sandvik LH517装载机的终传动 | Бортовой редуктор погрузчика Sandvik LH517

5. Hydraulic Cylinder (液压油缸, Гидравлический цилиндр): Converts hydraulic energy into linear motion to move the machine's attachments.
   Example: Epiroc MT42 mine truck's hydraulic cylinder | Epiroc MT42矿用卡车的液压油缸 | Гидравлический цилиндр карьерного самосвала Epiroc MT42

6. Track Link (履带节, Звено гусеницы): The individual metal sections that make up the track chain on tracked vehicles.
   Example: Epiroc FlexiROC T40 crawler rig's track link | Epiroc FlexiROC T40履带式钻机的履带节 | Звено гусеницы гусеничной буровой установки Epiroc FlexiROC T40

7. Relief Valve (溢流阀, Предохранительный клапан): A safety device in hydraulic systems that limits pressure to a set maximum.
   Example: Atlas Copco L8 rock drill's relief valve | Atlas Copco L8凿岩机的溢流阀 | Предохранительный клапан бурильной установки Atlas Copco L8

8. Slewing Bearing (回转支承, Поворотный подшипник): The large bearing that allows the upper structure of an excavator or crane to rotate.
   Example: Sandvik Ranger DX800 drilling rig's slewing bearing | Sandvik Ranger DX800钻机的回转支承 | Поворотный подшипник буровой установки Sandvik Ranger DX800

9. Air Filter (空气滤清器, Воздушный фильтр): Cleans the air entering the engine's combustion chamber to prevent damage.
   Example: Atlas Copco XAS 97 air compressor's air filter | Atlas Copco XAS 97空压机的空气滤清器 | Воздушный фильтр воздушного компрессора Atlas Copco XAS 97

10. Torque Converter (变矩器, Гидротрансформатор): A fluid coupling that transfers rotational power from the engine to the transmission.
    Example: Sandvik DD321 tunnel jumbo's torque converter | Sandvik DD321掘进台车的变矩器 | Гидротрансформатор проходческого комбайна Sandvik DD321
