Engineering & Part Definitions

1. Hydraulic Cylinder Seal Kit: This is a set of seals used to prevent fluid leakage in a hydraulic cylinder.        
Example: On the Epiroc Boomer 282 drill rig, the boom cylinder seal kit (`комплект уплотнений цилиндра стрелы`, `动臂油缸密封件`) is essential for precise articulation.        
       2. Track Roller: A component that supports the weight of the machine and guides the track link.        
Example: The Atlas Copco FlexiROC D50 crawler drill's track roller assembly (`каток опорный`, `支重轮`) provides stability on rough terrain.        
       3. Swing Bearing: A large-diameter bearing that allows the upper structure to rotate freely.        
Example: The Komatsu PC200-7 excavator's swing bearing (`опорно-поворотное устройство`, `回转支承`) facilitates a 360-degree rotation.        
       4. Hydraulic Breaker Piston: The key internal moving component of a hydraulic hammer.        
Example: The Sandvik BR3218 hydraulic breaker's breaker piston (`поршень гидромолота`, `液压破碎锤活塞`) delivers powerful blows for rock breaking.        
       5. Final Drive: The gearbox that provides the final speed reduction and torque increase to the tracks.        
Example: The Epiroc SmartROC T45 crawler drill's final drive motor (`конечный привод`, `终传动总成`) powers the machine's movement.        
       6. Main Control Valve: A complex manifold that directs hydraulic fluid to various actuators like cylinders and motors.        
Example: The Komatsu PC270-7 excavator's main control valve (`главный распределительный клапан`, `主控制阀`) controls all primary functions.        
       7. Solenoid Valve: An electro-mechanical valve that uses an electrical current to control fluid flow.        
Example: The Komatsu PC220 excavator's solenoid valve (`электромагнитный клапан`, `电磁阀`) precisely manages hydraulic pilot pressure.        
       8. Hydraulic Hose: A flexible tube used to transport hydraulic fluid under high pressure.        
Example: A Sandvik DE140 drill's hydraulic hose assembly (`гидравлический шланг`, `液压软管总成`) connects the pump to the actuators.        
       9. Gear Pump: A hydraulic pump that uses the meshing of gears to pump fluid.        
Example: The Atlas Copco SmartROC D65 drill's hydraulic gear pump (`шестеренчатый насос`, `齿轮泵`) supplies oil to various control circuits.        
       10. Relief Valve: A safety valve used to limit the maximum pressure in a hydraulic circuit.        
Example: The Komatsu PC200-7's main relief valve (`главный предохранительный клапан`, `主溢流阀`) protects the hydraulic system from overpressure.
