Glossary of Engineering Machinery Components
Hydraulic Pump (液压泵): A mechanical device that converts mechanical power into hydraulic energy. It is the heart of a hydraulic system, providing the necessary flow and pressure to operate hydraulic cylinders and motors.
Installation Location: Typically mounted on the engine or transmission of the machinery.
Example: Kawasaki K3V112 Hydraulic Pump, Part Number: K3V112DTP-9N21.
Travel Final Motor Drive (行走终传动): The final gear reduction and motor assembly that provides the rotational power to the tracks or wheels of an excavator or other heavy machinery, enabling movement.
Installation Location: Located within the undercarriage, directly connected to the tracks or wheels.
Example: Nachi Travel Motor, Part Number: PVD-2B-42CP-16G5.
Main Pump (主泵): The primary hydraulic pump in an excavator or other hydraulic machinery, responsible for supplying hydraulic fluid to the main hydraulic circuits, such as the boom, arm, and bucket cylinders.
Installation Location: Usually mounted directly to the engine flywheel housing.
Example: Rexroth A10VG63 Main Pump, Part Number: A10VG63DA2/10R-NSC01F023S.
Swing Motor (回转马达): The hydraulic motor that powers the rotation of the upper structure (house) of an excavator, allowing it to swing left or right.
Installation Location: Mounted on the upper structure, connected to the swing reduction gearbox.
Example: Kayaba Swing Motor, Part Number: PSVD2-27E.
Control Valve (控制阀): A valve that directs the flow of hydraulic fluid to different actuators (cylinders, motors) in a hydraulic system, controlling their movement and speed.
Installation Location: Typically located centrally in the hydraulic system, often near the main pump.
Example: Parker Hydraulic Control Valve, Part Number: D1VW004CNJW91.
Hydraulic Cylinder (液压缸): A linear actuator that converts hydraulic power into mechanical force and motion in a straight line. Used in excavators for boom, arm, and bucket movements.
Installation Location: Connected to the machine frame and the moving part (e.g., boom, arm).
Example: Hyva Hydraulic Cylinder, Part Number: 150-100-001.
Gear Pump (齿轮泵): A type of positive displacement pump that moves fluid by repeatedly enclosing a fixed volume using interlocking gears or cogs, transferring it mechanically. Often used in auxiliary hydraulic circuits.
Installation Location: Can be mounted on the engine or as part of the hydraulic system.
Example: Casappa Gear Pump, Part Number: PLP20.20-L1-CRF.
Track Roller (支重轮): Wheels located along the undercarriage frame that support the weight of the machine and allow the tracks to move smoothly.
Installation Location: Mounted on the undercarriage frame, below the tracks.
Example: Berco Track Roller, Part Number: B1100SR.
Idler (引导轮): A wheel located at the front of the undercarriage that helps to maintain track tension and guide the tracks.
Installation Location: Located at the front of the undercarriage frame.
Example: ITM Idler, Part Number: 0023011.
Slew Ring (回转支承): A large bearing that allows the upper structure of an excavator to rotate 360 degrees on the undercarriage.
Installation Location: Situated between the undercarriage and the upper structure.
Example: Rothe Erde Slew Ring, Part Number: 21-0300-1610.
Frequently Asked Questions
What are the common signs of a failing hydraulic pump in an excavator?
Common signs include slow or weak hydraulic functions, unusual noises from the pump, overheating of hydraulic fluid, and milky or foamy hydraulic oil.
How often should I replace the travel final motor drive in my mining equipment?
The lifespan of a travel final motor drive depends on various factors such as operating conditions, maintenance, and the quality of the part. Regular inspection for leaks, noises, and performance issues is recommended. Replacement should be based on these inspections and the manufacturer's recommendations.

Engine Troubleshooting: Overheating
Problem: Engine overheating in an excavator.
Possible Causes and Solutions:
- Low Coolant Level: Check the coolant level in the radiator and expansion tank. If low, add the recommended coolant mixture. Look for leaks in hoses, radiator, or water pump.
- Faulty Thermostat: The thermostat regulates the flow of coolant. If it's stuck closed, coolant cannot circulate properly, leading to overheating. Replace the thermostat.
- Clogged Radiator: Dust, debris, and scale buildup in the radiator can restrict airflow and reduce cooling efficiency. Clean the radiator fins with compressed air or water. Consider professional cleaning if heavily clogged.
- Water Pump Failure: The water pump circulates coolant through the engine. If it's not working correctly (e.g., due to a broken impeller), the engine can overheat. Inspect the water pump for leaks or unusual noises. Replace if necessary.
- Loose or Broken Fan Belt: The fan belt drives the cooling fan. If it's loose or broken, the fan won't spin at the correct speed, reducing cooling. Check the tension and condition of the fan belt. Adjust or replace as needed.
- Air in the Cooling System: Air pockets can prevent proper coolant circulation. Bleed the cooling system to remove trapped air.
