Technical Glossary of Machinery Components

Understanding your equipment is key to maintenance. Here are a few essential component explanations:

1. Fuel Injector (燃油喷射器 / Форсунка): Mounted in the cylinder head or manifold, delivers precisely metered fuel into the engine cylinders. Example: Komatsu PC400-7 Fuel Injector.
2. Water Pump (水泵 / Водяной насос): Located on the engine block, circulates coolant through the engine and radiator to regulate temperature. Example: Cummins ISX Water Pump.
3. Air Compressor (空气压缩机 / Воздушный компрессор): Usually engine-driven, it pressurizes air for the vehicle's air brake system or pneumatic tools. Example: Volvo FH16 Air Compressor.
4. Final Drive (终传动 / Бортовой редуктор): Situated at the end of the drive axle/tracks, it reduces speed and increases torque to the wheels or sprockets. Example: Caterpillar D8T Final Drive.
5. Tie Rod End (横拉杆端 / Наконечник рулевой тяги): Connects the steering rack to the steering knuckle, allowing the wheels to turn. Example: Mercedes-Benz Actros Tie Rod End.
6. Hydraulic Cylinder (液压油缸 / Гидроцилиндр): A linear actuator that converts hydraulic energy into mechanical force. Installed on booms, buckets, and blades. Example: John Deere 9470R Boom Cylinder.
7. Starter Motor (起动机 / Стартер): Attached to the engine flywheel, it provides the initial rotational force to start the internal combustion engine. Example: JCB 3CX Starter Motor.
8. Turbocharger (涡轮增压器 / Турбокомпрессор): Mounted on the exhaust manifold, uses exhaust gas to spin a turbine, which compresses intake air for increased engine power. Example: Garrett GT45 Turbocharger.
9. Alternator (交流发电机 / Генератор): Engine-driven, charges the battery and powers the electrical system when the engine is running. Example: Scania R450 Alternator.
10. Muffler (消音器 / Глушитель): Part of the exhaust system, reduces the noise emitted by the engine. Example: Massey Ferguson 5713 Muffler.

Troubleshooting: Heavy Truck Electrical Fault (Contrasting Color Block)

Equipment: Heavy Truck - Volvo VNX 740

Component: Alternator.

Fault: The battery warning light illuminates on the dashboard, and the voltage gauge reads low while the engine is running. This indicates the Alternator is not charging the system correctly.

Processing Scheme:

  1. Immediately check the alternator drive belt for tension and visible damage. A loose or broken belt will prevent the alternator from turning.

  2. Check the connections (power cables and excitation wiring) on the alternator and battery for corrosion or looseness. A bad connection can mimic a faulty alternator.

  3. If the belt and connections are good, a multimeter test should confirm the output voltage. A reading below 13.5V with the engine running suggests an internal failure of the alternator (e.g., failed rectifier or voltage regulator).

  4. Replace the faulty alternator with a new or properly remanufactured unit (e.g., Volvo VNX 740 Alternator Replacement) to restore proper charging voltage and prevent battery discharge.
