Randomly Added Definitions of Hydraulic Pumps and Travel Final Motor Drives:
- Hydraulic Pump (液压泵): The heart of a hydraulic system, converting mechanical power into hydraulic power by moving fluid. It is installed within the hydraulic system of the machinery. For example, a gear pump (齿轮泵) with part number 705-52-30320 is used in the Komatsu PC200-8 excavator.
- Travel Final Motor Drive (行走减速器): The component that provides the final reduction in speed and increase in torque to drive the machine's tracks or wheels. It is typically located within the undercarriage. An example is a swing motor (回转马达) part number 716-12-16100 used in a Hyundai R220-9 excavator.
- Hydraulic Pump - Gear Pump (液压泵 - 齿轮泵): A type of positive displacement pump that uses the meshing of gears to pump fluid by displacement. Often found in the main hydraulic circuit. For instance, part number 3977838 is a Cummins engine oil pump.
- Travel Final Motor Drive - Planetary Gearbox (行走减速器 - 行星齿轮箱): A gear system consisting of a central sun gear, several planet gears orbiting the sun, and an outer ring gear. Located within the final drive assembly. For example, a travel motor assembly (行走马达总成) with part number 91N1-01030 is used in a Doosan DX300LC excavator.
- Hydraulic Pump - Vane Pump (液压泵 - 叶片泵): A type of positive displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity. Often used in power steering systems. For example, part number 205-03-51120 is a hydraulic pump used in a Komatsu WA380 loader.
- Travel Final Motor Drive - Track Motor (行走减速器 - 履带马达): Specifically designed to power the movement of tracked machinery. Integrated into the track drive system. For instance, a track drive motor (履带驱动马达) with part number KCJ-1040 is used in a Kobelco SK200-8 excavator.
- Hydraulic Pump - Piston Pump (液压泵 - 柱塞泵): A type of positive displacement pump where the high-pressure seal reciprocates with the piston. Commonly used as the main hydraulic pump in excavators. An example is a main hydraulic pump (主液压泵) with part number K3V112DT used in a Kawasaki hydraulic system.
- Travel Final Motor Drive - Wheel Motor (行走减速器 - 轮式马达): Designed for wheeled machinery, providing the torque to rotate the wheels. Located directly within the wheel hub or connected via a drivetrain. For example, a wheel motor (轮式马达) with part number VOE14533496 is used in a Volvo L150H wheel loader.
- Hydraulic Pump - Bent Axis Pump (液压泵 - 斜轴式泵): A type of axial piston pump where the drive shaft and cylinder block are at an angle. Often used in closed-loop hydraulic systems. For example, part number PV90R100KA1BD15R1A00 is a Bosch Rexroth bent axis pump.
- Travel Final Motor Drive - Swing Reduction Gear (行走减速器 - 回转减速器): While technically for rotation, it's a final stage in the swing mechanism, similar to a travel final drive. Located in the upper structure of excavators. For instance, a swing gearbox (回转齿轮箱) with part number 206-26-00033 is used in a Komatsu PC300-7 excavator.
Small Common Knowledge Questions:
- What are the common causes of hydraulic pump failure? (液压泵常见的故障原因有哪些？) Common causes include fluid contamination, cavitation, overheating, and mechanical wear.
- How do I check the oil level in my travel final drive? (如何检查行走减速器的油位？) Typically, there is a sight glass or a level plug on the final drive housing that indicates the correct oil level. Refer to your machine's manual for specific instructions.
- What is the function of a pilot pump in an excavator? (挖掘机上先导泵的作用是什么？) The pilot pump provides hydraulic pressure to operate the control valves that direct the main hydraulic flow to various actuators like cylinders and motors.

Engine Troubleshooting Tip: Low Engine Oil Pressure
Symptom: The engine oil pressure warning light is on, or the oil pressure gauge indicates a low reading.
Possible Causes and Solutions:
- Low Oil Level: Check the oil dipstick and add oil to the recommended level.
- Faulty Oil Pressure Sensor: The sensor might be sending a false reading. Replace the sensor.
- Clogged Oil Filter: A blocked filter can restrict oil flow. Replace the oil filter.
- Worn Oil Pump: An aging or damaged oil pump may not be able to generate sufficient pressure. Consider replacing the oil pump.
- Internal Engine Issues: Worn bearings or other internal damage can lead to a drop in oil pressure. This might require a more detailed inspection and potential engine overhaul.
