Engineering Machinery Hydraulic Pumps and Travel Final Motor Drives Glossary

Hydraulic Pump (液压泵): The core power component in a hydraulic system, converting mechanical energy into hydraulic energy (pressure and flow). It is typically installed within the hydraulic system of the machinery.
Example: Hitachi Excavator, Model: ZX200, Part Name: Main Hydraulic Pump, Part Number: 9264171

Travel Final Drive (行走终传动): The assembly that transmits power from the travel motor to the machine's tracks or wheels, enabling movement. It is located at the end of the travel motor and connected to the undercarriage.
Example: Hitachi Excavator, Model: EX60, Part Name: Travel Motor Assembly, Part Number: 9148284

Gear Pump (齿轮泵): A type of positive displacement pump that moves fluid by repeatedly enclosing a fixed volume using interlocking cogs or gears, transferring it mechanically. Often found in the hydraulic system.
Example: Generic Excavator, Model: Various, Part Name: Hydraulic Gear Pump, Part Number: 705-52-30340

Axial Piston Pump (轴向柱塞泵): A type of hydraulic pump that uses the reciprocating motion of pistons in a rotating cylinder block to generate flow. Commonly used as the main hydraulic pump in excavators.
Example: Komatsu Excavator, Model: PC200, Part Name: Main Pump, Part Number: 708-1L-00312

Radial Piston Pump (径向柱塞泵): A hydraulic pump where the pistons move radially outwards from a central camshaft. Used in various hydraulic applications.
Example: Generic Hydraulic System, Model: N/A, Part Name: Radial Piston Pump, Part Number: V30D1U70

Hydraulic Motor (液压马达): Converts hydraulic energy (pressure and flow) back into mechanical energy, used to drive components like travel final drives or swing motors. Installed within the hydraulic circuit to provide rotational power.
Example: Caterpillar Excavator, Model: 320, Part Name: Swing Motor, Part Number: 157-3868

Planetary Gearbox (行星齿轮箱): A reduction gearbox used in travel final drives to increase torque and reduce speed from the travel motor to the tracks. Located within the travel final drive assembly.
Example: Volvo Excavator, Model: EC210, Part Name: Travel Gearbox, Part Number: VOE14527482

Swash Plate (斜盘): A component in axial piston pumps that the pistons reciprocate against, controlling the stroke and thus the flow rate. Located inside the axial piston pump.
Example: Hitachi Excavator, Model: ZX330, Part Name: Swash Plate, Part Number: 9237747

Spur Gear (正齿轮): A type of gear with teeth that run parallel to the axis of rotation, used in various parts of hydraulic pumps and final drives for power transmission. Found within gear pumps and gearboxes.
Example: Generic Hydraulic Pump, Model: N/A, Part Name: Drive Gear, Part Number: 0000-123456

Gerotor (内啮合转子泵): A type of positive displacement pump that uses an inner and outer rotor to create pumping action. Can be found in auxiliary hydraulic circuits.
Example: Generic Machinery, Model: Various, Part Name: Hydraulic Oil Pump, Part Number: 1R-1808

Frequently Asked Questions & Tips

What are the common signs of a failing hydraulic pump in an excavator?

Common signs include slow or weak hydraulic functions, unusual noises (whining or grinding), overheating of hydraulic oil, and foamy or milky hydraulic fluid.

How often should I replace the hydraulic filters on my mining equipment?

The replacement frequency depends on the operating environment and the manufacturer's recommendations. Generally, it's advisable to replace hydraulic filters every 500 to 1000 hours of operation or as indicated in the machine's service manual.

Why is it important to use the correct type of hydraulic oil in my machinery?

Using the wrong type of hydraulic oil can lead to decreased performance, increased wear and tear on hydraulic components, and potential system failures. Always refer to the manufacturer's specifications for the recommended hydraulic oil.

Engine Trouble: Overheating

Symptom: Engine temperature gauge reads high, steam or coolant is escaping from the radiator or overflow tank, and there might be a burning smell.

Possible Causes and Solutions:

Low Coolant Level: Check the coolant level in the radiator and overflow tank. If low, allow the engine to cool down and carefully add the correct type of coolant. Look for any leaks.
Faulty Thermostat: The thermostat regulates the flow of coolant. If it's stuck closed, the engine can overheat. A faulty thermostat will need to be replaced.
Radiator Issues: The radiator might be blocked internally or externally. Check for debris on the outside and consider flushing the radiator to remove internal blockages.
Water Pump Failure: The water pump circulates coolant. If it's not working correctly, the engine can overheat. Listen for unusual noises from the water pump area. A failing water pump needs replacement.
Loose or Damaged Belts: The fan and water pump are often driven by belts. Check the condition and tension of the belts. Replace any worn or loose belts.

If the overheating persists after checking these common issues, it's recommended to consult a qualified mechanic.
