Glossary of Engineering Machinery Hydraulic Pumps and Travel Final Motor Drives
Hydraulic Pump (液压泵) - A mechanical device that converts mechanical power into hydraulic power. It is installed in the hydraulic system of excavators to provide pressurized oil to hydraulic cylinders and motors.
Example: Kawasaki K3V112 hydraulic pump, Part Number: K3V112DTP-9N09. Installed in the main hydraulic system of excavators like the Komatsu PC200-8.
Travel Final Drive (行走减速器) - A gearbox connected to the hydraulic travel motor that reduces the motor's high-speed, low-torque output to the low-speed, high-torque required to drive the excavator's tracks.
Example: Nachi PVD-2B-42 travel motor and final drive, Part Number: PVD-2B-42P-6301G5. Found in excavators such as the Bobcat E32.
Main Pump (主泵) - The primary hydraulic pump in an excavator, responsible for supplying hydraulic fluid to most of the machine's functions, including the boom, arm, and bucket cylinders.
Example: Kayaba PSVD2-27E main pump, Part Number: PSVD2-27E-1. Commonly used in excavators like the Kubota KX91-3.
Swing Motor (回转马达) - A hydraulic motor that powers the rotation of the excavator's upper structure (house) relative to its undercarriage.
Example: M+S Hydraulic MS08 swing motor, Part Number: MS08-5-F12-A-2190. Used in various mini-excavator models.
Pilot Pump (先导泵) - A small hydraulic pump that provides the low-pressure hydraulic oil needed to operate the control valves in the excavator's hydraulic system.
Example: Casappa PLP20 pilot pump, Part Number: PLP20.20S1-L1-N. Often found in larger excavator models.
Gear Pump (齿轮泵) - A type of hydraulic pump that uses the meshing of gears to pump fluid by displacement. Commonly used for auxiliary functions in excavators.
Example: Parker PGP511 gear pump, Part Number: PGP511A0250CM1H2NE. Can be used for cooling or other auxiliary systems.
Track Motor (履带马达) - Another term for the hydraulic motor that, in conjunction with the final drive, propels the excavator's tracks.
Example: Rexroth MCR05 track motor, Part Number: MCR05A370F61Z3N0. Used in excavators like the Caterpillar 305.5E2.
Axial Piston Pump (轴向柱塞泵) - A type of hydraulic pump that uses reciprocating pistons to pump fluid. These are often used as the main pumps in excavators due to their high efficiency and pressure capabilities.
Example: Linde HPV-105 axial piston pump, Part Number: HPV-105-02R. Found in excavators such as the Liebherr R 914 Compact.
Boom Cylinder Hydraulic Pump (动臂油缸液压泵) - Refers to the hydraulic pump that supplies oil to the boom cylinder, which raises and lowers the excavator's boom. (Note: Typically the main pump supplies this function).
Example: Nachi PVS-1B-22 main pump (supplying boom cylinder), Part Number: PVS-1B-22-LXX-41. Used in some Yanmar excavator models.
Slew Motor (回转马达) - An alternative term for the swing motor, responsible for the excavator's upper structure rotation.
Example: Kawasaki KMB360 slew motor, Part Number: KMB360-1-35-1. Used in various mid-sized excavators.

Common Engine Failure and Solution: Overheating
Problem: Engine overheating is a common issue in construction machinery. It can be caused by several factors, including a low coolant level, a faulty thermostat, a clogged radiator, a malfunctioning water pump, or a damaged radiator hose.
Solution:
- Stop the machine immediately: If you notice the engine temperature gauge rising rapidly or the overheat warning light is on, stop the machine to prevent serious engine damage.
- Check the coolant level: Allow the engine to cool down before carefully checking the coolant level in the radiator and the coolant overflow tank. If the level is low, add the recommended coolant mixture.
- Inspect the radiator: Check for any external blockages such as dirt, debris, or bent fins. Clean the radiator with compressed air or water if necessary.
- Check for leaks: Inspect the radiator hoses, water pump, and other cooling system components for any signs of leaks. Replace any damaged hoses or components.
- Test the thermostat: A faulty thermostat can prevent proper coolant circulation. If you suspect a thermostat issue, it may need to be replaced.
- Check the water pump: Ensure the water pump is functioning correctly. A failing water pump will not circulate coolant effectively.
- Professional inspection: If the overheating issue persists after checking these common causes, it is recommended to have a qualified mechanic inspect the engine for more complex problems such as a blown head gasket or internal engine damage.
