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 energy. It is installed in the hydraulic system to provide pressurized oil flow.
Example: Kawasaki K3V112 Hydraulic Pump, Part Number: K3V112DTPH9N51

Main Pump (主泵): The primary hydraulic pump in an excavator, responsible for supplying oil to various actuators like the boom, arm, and bucket cylinders.
Example: Rexroth A10VSO71 Main Pump, Part Number: R902103034

Pilot Pump (先导泵): A smaller hydraulic pump that provides low-pressure oil to control the main hydraulic valves. It is usually mounted on the main pump.
Example: Nachi PVS2-13 Pilot Pump, Part Number: PVS2-13B-1-R-30

Travel Motor (行走马达): A hydraulic motor that converts hydraulic energy into rotational motion to drive the excavator's tracks. It is located in the undercarriage, connected to the final drive.
Example: Kayaba MAG-18 Travel Motor, Part Number: MAG-18-100F-1

Swing Motor (回转马达): A hydraulic motor that rotates the excavator's upper structure (house) allowing it to swing left or right. It is mounted on the upper structure, connected to the swing gearbox.
Example: Nabtesco GM21VL Swing Motor, Part Number: GM21VL-2-100

Control Valve (控制阀): Directs the flow of hydraulic oil to different actuators based on operator input. It is a central component in the hydraulic system.
Example: Kawasaki KDRDE5K-31/30C Control Valve, Part Number: KDRDE5K-31/30C-111-C1-L

Hydraulic Cylinder (液压缸): A linear actuator that converts hydraulic power into linear motion. Examples include boom cylinder, arm cylinder, and bucket cylinder. These are located at various articulation points of the excavator.
Example: Boom Cylinder for Komatsu PC200-8, Part Number: 707-99-45001

Final Drive (行走减速器): A gearbox connected to the travel motor that reduces the motor's high-speed, low-torque output to a lower speed, higher-torque output suitable for driving the tracks. It is located within the undercarriage, directly connected to the tracks.
Example: Final Drive for Caterpillar 320D, Part Number: 312-9777

Gear Pump (齿轮泵): A type of positive displacement pump that uses meshing gears to pump fluid. Often used in auxiliary hydraulic circuits.
Example: Casappa PLP20 Gear Pump, Part Number: PLP20.20-S1-L-FD/N

Axial Piston Pump (轴向柱塞泵): A type of positive displacement pump where pistons move parallel to the pump's axis of rotation. Commonly used as the main hydraulic pump in excavators.
Example: Linde HPV105 Axial Piston Pump, Part Number: HPV105-02R

Engine Troubleshooting: Excessive Black Smoke

Problem: The engine is emitting excessive black smoke during operation.

Possible Causes and Solutions:

Dirty or Clogged Air Filter: Restricts airflow, leading to incomplete combustion. Solution: Inspect the air filter and clean or replace it as needed. Refer to the engine's service manual for the correct air filter replacement procedure and intervals.
Faulty Fuel Injectors: Can cause over-fueling or improper fuel atomization. Solution: Have the fuel injectors inspected and tested by a qualified technician. They may need to be cleaned, repaired, or replaced.
Incorrect Fuel Injection Timing: Improper timing can lead to incomplete combustion. Solution: A qualified mechanic should check and adjust the fuel injection timing according to the engine's specifications.
Turbocharger Issues: A malfunctioning turbocharger can result in insufficient air supply. Solution: Inspect the turbocharger for damage or leaks. If issues are found, repair or replacement may be necessary.
Low Compression: Worn piston rings or valves can cause low compression, leading to poor combustion. Solution: Perform a compression test to check the engine's condition. Engine overhaul or component replacement might be required.
