Key Engineering Machinery Components Explained

• Fuel Transfer Pump (Supply Pump): A component (like CAT E320C + CAT3304 + 137-5541 Fuel Pump) that draws fuel from the tank and delivers it to the fuel injection pump. Located in the engine bay, usually mounted on the engine block.

• Boom Cylinder: A hydraulic cylinder that controls the lifting and lowering of the excavator boom. Epiroc Parts + SmartROC D65 + Boom Cylinder (Eng: Boom Cylinder, Rus: Цилиндр стрелы).

• Rock Drill Mechanism (Drifter): The component on a surface or underground drill rig that provides the impact and rotation for drilling. Sandvik Parts + DP1500i + Drifter (Eng: Drifter, Rus: Перфоратор).

• Hydraulic Motor (Traction Motor): Converts hydraulic energy into mechanical rotational energy to drive the tracks or wheels. Atlas Copco Parts + MT6020 + Traction Motor (Eng: Traction Motor, Rus: Тяговый двигатель).

• Sprocket: A toothed wheel that engages with the tracks (chain) to transmit power in tracked vehicles. Located at the rear drive end of the undercarriage.

• Relief Valve: A safety valve in the hydraulic system that limits the maximum pressure to protect components. Located within the main control valve or pump.

• Pilot Filter: A small filter element that cleans the hydraulic fluid used for pilot (control) pressure lines. Located near the pilot control valve or pump.

• Track Roller (Lower Roller): Supports the weight of the machine and guides the track chain on the undercarriage. Located on the bottom side of the track frame.

• Injector Nozzle: The component that sprays atomized fuel into the combustion chamber of a diesel engine. Located on the engine cylinder head.

• Seal Kit (Hydraulic): A set of rubber and plastic seals used to prevent fluid leakage and maintain pressure within a hydraulic component (e.g., cylinder, pump). Located inside the hydraulic component.
