Common Engineering Machinery Hydraulic Pumps and Travel Final Motor Drives - Definitions and Examples
Hydraulic Pump (液压泵) - A mechanical device that converts mechanical power into hydraulic power. It generates flow with enough power to overcome the pressure induced by the load at the system outlet. Installed in the hydraulic system to power various actuators. Example: Hitachi Excavator ZX200-3 Main Hydraulic Pump, Part Number: 9264391.
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 a lower speed, higher-torque output suitable for driving the machine's tracks or wheels. Installed in the undercarriage, directly connected to the tracks or wheels. Example: Komatsu PC200-7 Travel Motor and Final Drive Assembly, Part Number: 708-1L-00412.
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 using a cyclic pumping action. Used in various hydraulic circuits for low to medium pressure applications. Example: Caterpillar 320D Gear Pump, Part Number: 349-1068.
Axial Piston Pump (轴向柱塞泵) - A type of hydraulic pump that uses reciprocating pistons in a cylinder block to generate flow. The pistons move parallel to the axis of rotation of the cylinder block. Commonly used as the main hydraulic pump in excavators and other heavy machinery. Example: Hitachi ZX330-3 Main Hydraulic Pump, Part Number: 9270564.
Radial Piston Pump (径向柱塞泵) - A type of hydraulic pump where the pistons move radially in and out relative to the central axis of the pump. Often used in high-pressure applications. Example: Rexroth R902103426 Radial Piston Pump.
Hydraulic Motor (液压马达) - A rotary actuator that converts hydraulic power into mechanical power. Used to drive wheels, tracks, and other rotating components in machinery. Example: Kobelco SK200-8 Travel Motor, Part Number: LQ10V00017F1.
Swing Motor (回转马达) - A hydraulic motor specifically designed to rotate the upper structure (house) of an excavator. Installed in the upper structure, connected to the swing gearbox. Example: Hyundai R220-9 Swing Motor, Part Number: 31Q3-10130.
Control Valve (控制阀) - A valve that directs the flow of hydraulic fluid to different parts of the hydraulic system, controlling the movement and operation of actuators. Integrated within the hydraulic system, often near the main pump. Example: Volvo EC210B Main Control Valve, Part Number: VOE14524712.
Track Roller (支重轮) - A wheel in the undercarriage of tracked machinery that supports the weight of the machine and allows the tracks to move smoothly. Part of the undercarriage, located along the length of the track frame. Example: Shantui SD16 Track Roller, Part Number: 154-30-12213.
Slew Ring (回转支承) - A large bearing that allows the upper structure of an excavator to rotate 360 degrees on the undercarriage. Located between the upper structure and the undercarriage. Example: Doosan DX225LC Slew Ring Bearing, Part Number: 2713-1017A.

Common Engine Failure and Solution
Problem: Overheating Engine
Details: 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 even a damaged radiator hose. If the engine temperature gauge shows a reading in the red zone or a warning light illuminates, it indicates overheating.
Solution:
- Stop Operation Immediately: If you notice the engine is overheating, stop operating the machinery immediately to prevent severe engine damage.
- Check Coolant Level: Allow the engine to cool down, then carefully check the coolant level in the radiator and the coolant overflow tank. If the level is low, add the appropriate coolant mixture.
- Inspect for Leaks: Check for any visible leaks in the radiator, hoses, and around the water pump. Repair or replace any damaged components.
- Check the Radiator: Ensure the radiator fins are clean and free of debris. Clean them carefully with compressed air or water if necessary.
- Test the Thermostat: A faulty thermostat can prevent proper coolant circulation. A mechanic can test the thermostat and replace it if needed.
- Inspect the Water Pump: A malfunctioning water pump won't circulate coolant effectively. Listen for unusual noises coming from the water pump area. If suspected, have it inspected and potentially replaced.
- Professional Inspection: If the overheating issue persists after checking these common causes, it's recommended to have a qualified mechanic inspect the engine for more complex problems, such as a blown head gasket or internal engine damage.
