Glossary of Engineering Machinery Hydraulic Pumps and Travel Final Motor Drives
Hydraulic Pump (液压泵): The heart of the hydraulic system, converting mechanical energy into hydraulic energy. Installed within the main hydraulic system of the excavator. Example: Hitachi Excavator EX200-5 Main Hydraulic Pump, Part Number: 9147340.
Travel Final Motor Drive (行走减速机总成): The component that provides the final reduction in speed and increase in torque to drive the excavator's tracks or wheels, enabling movement. Located in the undercarriage, attached to the tracks or wheel axles. Example: Hitachi Excavator ZX30U-3 Travel Motor, Part Number: 4691489.
Main Hydraulic Pump (主液压泵): The primary pump responsible for supplying hydraulic power to all the main functions of the excavator, such as the boom, arm, bucket, and swing. Located within the central hydraulic compartment. Example: Hitachi EX120-5 Main Hydraulic Pump, Part Number: 9151416.
Pilot Pump (先导泵): A smaller pump that supplies hydraulic pressure to the control valves, making them easier to operate. Typically mounted near the main hydraulic pump. Example: Hitachi Excavator Pilot Pump, Part Number: 9143891.
Swing Motor (回转马达): The hydraulic motor responsible for rotating the upper structure (house) of the excavator. Located in the upper structure, connected to the swing gearbox. Example: Hitachi Excavator Swing Motor, Part Number: 9185903.
Boom Cylinder (动臂油缸): A hydraulic cylinder that lifts and lowers the main boom of the excavator. Attached to the boom structure. Example: Hitachi Excavator Boom Cylinder, Part Number: 9203861.
Arm Cylinder (斗杆油缸): A hydraulic cylinder that controls the movement of the excavator's arm (dipper stick). Connected between the boom and the bucket. Example: Hitachi Excavator Arm Cylinder, Part Number: 9203862.
Bucket Cylinder (铲斗油缸): A hydraulic cylinder that controls the digging and dumping action of the excavator's bucket. Attached to the end of the arm. Example: Hitachi Excavator Bucket Cylinder, Part Number: 9203863.
Track Motor (行走马达): Another term for the hydraulic motor within the travel final drive that powers the tracks. Located inside the travel final drive unit. Example: Hitachi Excavator Track Motor, Part Number: 9264329.
Gear Pump (齿轮泵): A type of hydraulic pump that uses gears to displace fluid. Can be used in various auxiliary systems of an excavator. Typically located within the hydraulic system. Example: Hitachi Excavator Gear Pump, Part Number: 4635287.
Common Knowledge about Engineering Machinery
Did you know that regular hydraulic oil changes are crucial for the longevity of your excavator's hydraulic system? Contaminated or degraded oil can lead to increased wear and tear on pumps, motors, and cylinders.
Understanding the part number system of your machinery can greatly help in quickly identifying and ordering the correct replacement parts, minimizing downtime.
Proper maintenance of the excavator's undercarriage, including regular inspection and lubrication of tracks and rollers, is essential for smooth operation and reduced wear.

Common Engine Failure and Solution: Overheating
Symptom: The engine temperature gauge reads high, steam may be coming from under the hood, and the engine might lose power or stall.
Possible Causes and Solutions:
- Low Coolant Level: Check the coolant level in the radiator and expansion tank. Replenish as needed with the correct type of coolant.
- Radiator Issues: Inspect the radiator for leaks or blockages (internal or external). Clean the radiator fins from any debris. If there are leaks or severe blockages, the radiator may need repair or replacement.
- Thermostat Malfunction: The thermostat regulates the flow of coolant. If it's stuck closed, the engine will overheat. A faulty thermostat needs replacement.
- Water Pump Failure: The water pump circulates coolant through the engine. If it's not working correctly (due to a broken impeller or belt), the engine can overheat. Inspect the water pump and its drive belt. Replace if necessary.
- Loose or Damaged Belts: Check the condition and tension of the belts driving the water pump and fan. Replace or tighten as needed.
