Part Name Explanations:
Sensor: A device that detects and measures a physical property and records, indicates, or otherwise responds to it. For example, Komatsu PC200-8 uses a temperature sensor (温度传感器, датчик температуры) to monitor engine coolant temperature.
Solenoid Valve: An electromechanically operated valve controlled by an electric current through a solenoid. For instance, a Komatsu PC300-7 uses a hydraulic solenoid valve (液压电磁阀, гидравлический электромагнитный клапан) to control the flow of hydraulic oil to the actuators.
Wiring Harness: An assembly of electrical wires or cables which transmit signals or electrical power. A engine wiring harness (发动机线束, жгут проводов двигателя) in a Komatsu D85EX connects various engine components to the control system.
Boom Cylinder: A hydraulic cylinder used to raise and lower the boom of an excavator or other heavy equipment. The boom cylinder (动臂油缸, гидроцилиндр стрелы) on a Komatsu PC200-8 is essential for lifting operations.
Hydraulic Gear Pump: A type of positive displacement pump that uses the meshing of gears to pump fluid. A hydraulic gear pump (液压齿轮泵, гидравлический шестеренный насос) in a Komatsu D65EX provides hydraulic power for various functions.
Injector Pump: In diesel engines, this pump delivers fuel at high pressure to the injectors. The injector pump (喷油泵, топливный насос высокого давления) in a Komatsu S6D125 engine ensures proper fuel delivery for combustion.
Pressure Switch: A device that opens or closes an electrical circuit based on the pressure of a fluid. A pressure switch (压力开关, реле давления) in a Komatsu HD785-7 can monitor hydraulic system pressure.
Alternator Regulator: A component that controls the output voltage of the alternator, ensuring the battery is properly charged. The alternator regulator (交流发电机调节器, регулятор генератора) in a Komatsu WA470-6 maintains the electrical system's voltage.
Radiator Core: The central part of a radiator where heat exchange occurs between the engine coolant and the outside air. The radiator core (散热器芯, сердцевина радиатора) in a Komatsu PC1250-8 is crucial for engine cooling.
Accumulator: A pressure storage reservoir in a hydraulic system that stores hydraulic energy to smooth out pressure pulses and provide extra power when needed. The accumulator (蓄能器, гидроаккумулятор) in a Komatsu HM400-2 can assist with braking or steering.
Common Knowledge about Heavy Equipment Parts:
Question: How often should I replace the hydraulic filters in my Komatsu excavator? Answer: Hydraulic filters should typically be replaced every 250 to 500 hours of operation, or as recommended by the Komatsu service manual, to prevent contamination and ensure optimal hydraulic system performance.
Question: What are the signs of a failing fuel injector in a diesel engine? Answer: Signs can include rough idling, decreased fuel efficiency, black smoke from the exhaust, and engine misfires. Prompt replacement is crucial to avoid further engine damage.
Question: Why is it important to use genuine Komatsu parts? Answer: Genuine Komatsu parts are designed and manufactured to the exact specifications of your machine, ensuring optimal performance, reliability, and longevity. While aftermarket options exist, genuine parts offer the best fit and quality, potentially saving you money in the long run by reducing downtime and the risk of premature failure.

Troubleshooting Tip: Excessive Black Smoke from a Komatsu Diesel Engine
Problem: A Komatsu excavator PC200-8 is emitting excessive black smoke from the exhaust, and the engine seems to lack power.
Possible Causes and Solutions:
Dirty Air Filter: A clogged air filter restricts airflow to the engine, leading to incomplete combustion and black smoke. Solution: Check the air filter and replace it if it's dirty or clogged.
Faulty Fuel Injectors: Malfunctioning fuel injectors can deliver too much fuel or atomize it poorly, causing black smoke. Solution: Have the fuel injectors inspected and tested. Clean or replace any faulty injectors.
Incorrect Fuel Injection Timing: Improper timing can lead to incomplete combustion. Solution: Check and adjust the fuel injection timing according to the Komatsu service manual.
Low Fuel Quality: Using low-quality fuel can also result in black smoke. Solution: Ensure you are using the correct grade and quality of fuel recommended for your Komatsu engine.
Turbocharger Issues: If the turbocharger is not functioning correctly, it may not be providing enough air for combustion. Solution: Inspect the turbocharger for any damage or leaks. Repair or replace it as necessary.
Note: It is always recommended to consult the Komatsu service manual and engage a qualified technician for diagnosis and repairs.
