Explore Our Range of Hydraulic Pumps and Travel Final Motor Drives

Hydraulic Pump (液压泵) - A mechanical device that converts mechanical power into hydraulic energy. It is a vital component in the hydraulic system of excavators.

Installation Location: Typically mounted on the engine or within the hydraulic system compartment.
Example: Kawasaki Hydraulic Pump K3V112
Part Number: K3V112BDT-9N09

Travel Final Drive (行走减速器) - The final gear reduction unit that transmits power to the tracks or wheels, enabling the excavator to move.

Installation Location: Attached to the undercarriage, directly connected to the tracks or wheels.
Example: Nachi Travel Motor GM06VL
Part Number: GM06VL-E-31-R

Main Pump (主泵) - The primary hydraulic pump in an excavator, responsible for supplying hydraulic power to various actuators like the boom, arm, and bucket.

Installation Location: Usually mounted directly to the engine's power takeoff.
Example: Kayaba Main Pump PSVD2-27E
Part Number: PSVD2-27E-1

Swing Motor (回转马达) - The hydraulic motor that powers the rotation of the excavator's upper structure (house).

Installation Location: Located in the upper structure, connected to the swing gearbox.
Example: M+S Hydraulic Swing Motor MS08
Part Number: MS08-5-1111-F050

Pilot Pump (先导泵) - A small hydraulic pump that provides the pilot pressure required to control the main hydraulic valves.

Installation Location: Often integrated with the main pump or mounted separately on the engine.
Example: Rexroth Pilot Pump AZPF-12-004RRR20MB
Part Number: AZPF-12-004RRR20MB

Track Motor (履带马达) - Another term for the travel final drive motor, specifically for tracked excavators.

Installation Location: Attached to the undercarriage, driving the tracks.
Example: Tong Myung Track Motor TM40VC
Part Number: TM40VC-B-100

Gear Pump (齿轮泵) - A type of hydraulic pump that uses meshing gears to pump fluid. Often used for auxiliary functions.

Installation Location: Can be found in various locations depending on the application.
Example: Parker Gear Pump PGP511A0200CD1D2
Part Number: PGP511A0200CD1D2

Axial Piston Pump (轴向柱塞泵) - A type of hydraulic pump that uses pistons in a rotating cylinder block to pump fluid. Commonly used as the main pump in excavators.

Installation Location: Typically mounted on the engine.
Example: Linde Axial Piston Pump HPV105-02R
Part Number: HPV105-02R

Radial Piston Motor (径向柱塞马达) - A type of hydraulic motor where the pistons move radially to rotate the output shaft. Can be used in travel final drives.

Installation Location: Integrated into the travel final drive unit.
Example: Staffa Radial Piston Motor HMB031
Part Number: HMB031U57A1

Orbital Motor (摆线马达) - A type of hydraulic motor that uses a rotating valve and gear set to produce torque. Often used for attachments.

Installation Location: Typically mounted on the attachment.
Example: Eaton Char-Lynn Orbital Motor 101-1007-009
Part Number: 101-1007-009

Common Engine Failure and Solution:

Problem: Engine Overheating

Details: The engine temperature gauge is consistently high, and steam or coolant may be escaping from the radiator or overflow tank. This can lead to significant engine damage if not addressed promptly.

Possible Causes:

Low coolant level
Faulty thermostat
Leaking radiator or hoses
Damaged water pump
Blocked radiator fins
Loose or broken fan belt

Troubleshooting and Solution:

Check Coolant Level: Ensure the coolant level in the radiator and overflow tank is within the recommended range. If low, add the appropriate coolant mixture.
Inspect for Leaks: Examine the radiator, hoses, and connections for any signs of leaks. Repair or replace any damaged components.
Check Thermostat: A faulty thermostat can prevent proper coolant circulation. Test the thermostat or replace it if necessary.
Inspect Water Pump: Check for any signs of leakage or damage to the water pump. A malfunctioning water pump will not circulate coolant effectively.
Clean Radiator Fins: Remove any dirt, debris, or obstructions from the radiator fins to ensure proper airflow.
Check Fan Belt: Ensure the fan belt is in good condition and properly tensioned. Replace a loose or broken belt.
Professional Inspection: If the issue persists after checking these points, consult a qualified mechanic for further diagnosis, which may involve checking for internal engine problems like a blown head gasket.
