Understanding Key Components: Hydraulic Pumps and Travel Final Motor Drives
To help you better understand the components we offer, here are some common terms and their explanations:
1. Hydraulic Main Pump (液压主泵)
Location: Usually installed in the engine compartment and directly driven by the engine.
Description: The core component of the hydraulic system, responsible for converting mechanical energy into hydraulic energy to power various actuators.
Example: HITACHI Excavator ZX200-3, Main Hydraulic Pump, Part Number: 9267906
2. Hydraulic Swing Motor (回转马达)
Location: Mounted on the upper structure of the excavator, responsible for rotating the machine's upper body.
Description: Converts hydraulic energy into rotational motion, allowing the excavator to swing.
Example: HITACHI Excavator ZX210LC-5, Swing Motor, Part Number: 9270348
3. Travel Final Drive (行走减速器)
Location: Integrated within the undercarriage, connected to the track chains.
Description: A gearbox that reduces the high-speed, low-torque output of the travel motor to a lower speed, higher torque suitable for moving the excavator.
Example: HITACHI Excavator EX60-5, Travel Final Drive, Part Number: 9143863
4. Hydraulic Control Valve (液压控制阀)
Location: Typically located near the hydraulic pump and actuators.
Description: Directs the flow of hydraulic fluid to various parts of the system, controlling the movement and force of cylinders and motors.
Example: HITACHI Excavator ZX330-3, Control Valve, Part Number: 9264712
5. Hydraulic Cylinder (液压油缸)
Location: Used in various parts of the excavator, such as the boom, arm, and bucket.
Description: Converts hydraulic energy into linear motion, used for lifting, digging, and other operations.
Example: HITACHI Excavator EX200-2, Boom Cylinder, Part Number: 9130291
6. Hydraulic Pilot Valve (液压先导阀)
Location: Usually integrated with the main control valve or located near the operator's levers.
Description: A small valve that controls the pressure and flow of hydraulic fluid to the main control valve, allowing for precise operation.
Example: HITACHI Excavator ZAXIS 70, Pilot Valve, Part Number: 9216437
7. Hydraulic Gear Pump (液压齿轮泵)
Location: Can be used for auxiliary systems or in smaller machinery.
Description: A type of positive displacement pump that uses the meshing of gears to pump fluid.
Example: HITACHI Wheel Loader ZW180-5, Hydraulic Gear Pump, Part Number: 4716075
8. Travel Motor (行走马达)
Location: Mounted within the undercarriage, connected to the travel final drive.
Description: Converts hydraulic energy into rotational motion to drive the excavator's tracks.
Example: HITACHI Excavator EX120-5, Travel Motor, Part Number: 9146082
9. Hydraulic Relief Valve (液压溢流阀)
Location: Found throughout the hydraulic system.
Description: A safety valve that limits the maximum pressure in the hydraulic system to prevent damage.
Example: HITACHI Excavator ZX240-3, Relief Valve, Part Number: 9268319
10. Hydraulic Accumulator (液压蓄能器)
Location: Can be found in various parts of the hydraulic system.
Description: A pressure storage device that stores hydraulic energy to smooth out pressure fluctuations or provide power for auxiliary functions.
Example: HITACHI Excavator EX300-5, Accumulator, Part Number: 9148764

Common Engine Problem and Solution: Engine Overheating
Problem Description: The excavator engine temperature rises above the normal operating range, potentially leading to performance issues and engine damage.
Possible Causes:
- Low coolant level.
- Faulty thermostat.
- Clogged radiator fins or internal passages.
- Defective water pump.
- Loose or damaged fan belt.
- Incorrect engine oil level or type.
- Air trapped in the cooling system.
Troubleshooting and Solutions:
- Check Coolant Level: Ensure the coolant level in the radiator and expansion tank is within the recommended range. If low, check for leaks and replenish with the correct coolant type.
- Inspect Thermostat: A malfunctioning thermostat can prevent proper coolant circulation. Test or replace the thermostat if necessary.
- Clean Radiator: Inspect the radiator fins for debris and clean them with compressed air or water. Flush the radiator to remove any internal blockages.
- Check Water Pump: Look for signs of leakage or unusual noise from the water pump. A faulty water pump needs replacement.
- Inspect Fan Belt: Ensure the fan belt is in good condition and has the correct tension. Replace a worn or loose belt.
- Verify Engine Oil: Check the engine oil level and ensure it is the correct type and viscosity.
- Bleed Cooling System: Remove any trapped air from the cooling system by following the manufacturer's instructions.
If the overheating issue persists after performing these checks, consult a qualified mechanic for further diagnosis and repair.
