Glossary of Engineering Machinery Hydraulic Pumps and Travel Final Motor Drives
1. Axial Piston Pump (轴向柱塞泵)
Location: Typically installed within the hydraulic system of the machinery, often near the engine or hydraulic oil tank.
Description: A type of hydraulic pump that uses reciprocating pistons in a cylinder block to generate hydraulic power.
Example: HITACHI Excavator ZX200-3, Hydraulic Main Pump, Part Number: 9264628
2. Gear Pump (齿轮泵)
Location: Can be found in various parts of the hydraulic system, often used for lower-pressure applications like lubrication or pilot circuits.
Description: A positive displacement hydraulic pump that uses meshing gears to pump fluid.
Example: Komatsu Excavator PC200-8, Gear Pump (for pilot circuit), Part Number: 702-21-55000
3. Vane Pump (叶片泵)
Location: Usually located within the hydraulic system, known for their quiet operation.
Description: A type of hydraulic pump that uses vanes mounted on a rotor to displace fluid.
Example: Caterpillar Excavator 320D, Vane Pump (for steering), Part Number: 232-6279
4. Travel Motor (行走马达)
Location: Mounted within the undercarriage of the excavator or other tracked machinery, directly connected to the final drive gearbox.
Description: A hydraulic motor that converts hydraulic power into rotational motion to drive the tracks or wheels, enabling the machine to move.
Example: HITACHI Excavator ZX200-3, Travel Motor (Left), Part Number: 9237930
5. Final Drive (行走减速器)
Location: Attached to the travel motor within the undercarriage, connected to the tracks or wheels.
Description: A gearbox that reduces the high-speed, low-torque output of the travel motor to a lower speed and higher torque suitable for propelling the machine.
Example: HITACHI Excavator ZX200-3, Final Drive Assembly (Left), Part Number: 9237933
6. Swash Plate (斜盘)
Location: Inside an axial piston hydraulic pump, it's a key component that controls the stroke of the pistons.
Description: An angled plate that causes the pistons in an axial piston pump to reciprocate as the cylinder block rotates, thus pumping hydraulic fluid.
Example: HITACHI Excavator ZX200-3, Swash Plate, Part Number: 9264631
7. Pilot Pump (先导泵)
Location: Often a smaller gear pump mounted on the main hydraulic pump or engine.
Description: A small hydraulic pump that provides the control pressure for the main hydraulic valves and other hydraulic components.
Example: Caterpillar Excavator 320D, Pilot Pump, Part Number: 207-00-71231
8. Hydraulic Cylinder (液压缸)
Location: Used throughout the machinery to perform various tasks like lifting the boom, arm, and bucket.
Description: A linear actuator that converts hydraulic power into linear motion and force.
Example: HITACHI Excavator ZX200-3, Boom Cylinder, Part Number: 9237901
9. Hydraulic Valve (液压阀)
Location: Integrated into the hydraulic system to control the direction, pressure, and flow of hydraulic fluid.
Description: A component that directs and regulates the flow of hydraulic oil within the system.
Example: Komatsu Excavator PC200-8, Main Control Valve, Part Number: 20Y-60-31202
10. Planetary Gear (行星齿轮)
Location: A key component within the travel final motor drive, responsible for the speed reduction.
Description: A gear system consisting of a central sun gear, several planet gears revolving around it, and an outer ring gear.
Example: HITACHI Excavator ZX200-3, Planetary Gear Set (in final drive), Part Number: 9237936

Engine Troubleshooting: Overheating
Problem: Engine Overheating in an Excavator
Details: The excavator engine temperature gauge is consistently reading high, and there might be steam or a burning smell coming from the engine compartment. This can lead to reduced performance and potential engine damage if not addressed promptly.
Possible Causes and Solutions:
Low Coolant Level: Check the coolant level in the radiator and the overflow tank. If low, add the correct type of coolant mixture. Look for any leaks in the hoses, radiator, or engine block.
Faulty Thermostat: The thermostat regulates the flow of coolant. If it's stuck closed, the engine will overheat. A mechanic can test and replace a faulty thermostat.
Clogged Radiator: Debris, dirt, or scale buildup in the radiator can restrict coolant flow and reduce its efficiency. Flush the radiator and cooling system. Consider professional cleaning if heavily clogged.
Water Pump Issues: The water pump circulates coolant. If it's failing, coolant won't flow properly. Listen for unusual noises from the pump and check for leaks. A failing water pump needs replacement.
Fan Problems: The engine cooling fan helps dissipate heat. Ensure the fan blades are intact and that the fan clutch (if equipped) is functioning correctly. Check for any obstructions blocking airflow to the radiator.
Air in the Cooling System: Air pockets can prevent proper coolant circulation. Bleed the cooling system to remove trapped air.
Head Gasket Leak: A blown head gasket can cause combustion gases to enter the cooling system, leading to overheating. This is a serious issue requiring professional diagnosis and repair. Symptoms might include white smoke from the exhaust and coolant loss.
Note: Always allow the engine to cool down completely before attempting to check the coolant level or radiator. If you are not comfortable performing these checks, consult a qualified mechanic.
