Engineering Machinery Hydraulic Pumps and Travel Final Motor Drives Glossary

Hydraulic Pump (液压泵) - A mechanical device that converts mechanical power into hydraulic energy. It is a crucial component in the hydraulic system of excavators.
Installation Location: Engine compartment, connected to the engine's power output.
Example: Hitachi Excavator Zaxis ZX200-3 Main Hydraulic Pump, Part Number: 9264904

Travel Final Motor Drive (行走终传动) - The final gear reduction and hydraulic motor assembly that powers the excavator's tracks, enabling it to move.
Installation Location: Inside the excavator's track frame.
Example: Komatsu Excavator PC200-8 Travel Motor Assembly, Part Number: 708-1L-00412

Gear Pump (齿轮泵) - A type of positive displacement pump that uses meshing gears to pump fluid. Commonly used in excavator hydraulic systems.
Installation Location: Often found within the main hydraulic pump assembly or as an auxiliary pump.
Example: Caterpillar Excavator 320D Gear Pump, Part Number: 349-1068

Axial Piston Pump (轴向柱塞泵) - A type of positive displacement pump where the pistons move parallel to the axis of the cylinder block. Widely used as the main hydraulic pump in excavators.
Installation Location: Engine compartment, driven by the engine.
Example: Volvo Excavator EC210B Main Hydraulic Pump, Part Number: VOE14523180

Radial Piston Pump (径向柱塞泵) - A type of positive displacement pump where the pistons move radially to the axis of the cylinder block. Used in some excavator hydraulic systems for specific functions.
Installation Location: Can be found in various locations depending on the application.
Example: Liebherr Excavator R914 Radial Piston Pump, Part Number: 9446847

Swing Motor (回转马达) - A hydraulic motor that powers the rotation of the excavator's upper structure (house).
Installation Location: Mounted on the upper structure, connected to the swing gearbox.
Example: Kobelco Excavator SK200-8 Swing Motor, Part Number: LQ10V00017F1

Track Motor (履带马达) - Another term for the travel final motor drive, specifically referring to the hydraulic motor component.
Installation Location: Inside the track frame, part of the travel final drive assembly.
Example: Doosan Excavator DX225LC Track Motor, Part Number: 2705-9027A

Pilot Pump (先导泵) - A small hydraulic pump that provides the pilot pressure required to control the main hydraulic valves in an excavator.
Installation Location: Usually attached to the main hydraulic pump.
Example: Hyundai Excavator R220LC-9 Pilot Pump, Part Number: 31Q6-10130

Control Valve (控制阀) - Directs the flow of hydraulic fluid to various actuators (cylinders, motors) in the excavator's hydraulic system.
Installation Location: Typically located centrally in the hydraulic system.
Example: Sumitomo Excavator SH210-5 Control Valve, Part Number: KDRDE5K-31/30C50-121

Hydraulic Cylinder (液压缸) - A linear actuator that converts hydraulic power into linear motion. Used for various functions like lifting the boom, arm, and bucket.
Installation Location: Attached to the boom, arm, and bucket.
Example: JCB Excavator JS220 Boom Cylinder, Part Number: 20/925551

Common Questions about Our Main Business

Engine Troubleshooting: Excessive Black Smoke

Problem: Excessive black smoke emitting from the excavator's engine.

Possible Causes and Solutions:

Clogged Air Filter: A dirty air filter restricts airflow, leading to incomplete combustion and black smoke. Solution: Inspect and replace the air filter if necessary.
Faulty Injectors: Malfunctioning fuel injectors can deliver too much fuel or atomize it poorly, resulting in black smoke. Solution: Have the fuel injectors inspected and tested by a qualified technician. Clean or replace faulty injectors.
Incorrect Fuel Pump Timing: Improper fuel injection timing can cause incomplete combustion. Solution: Consult the engine's service manual and adjust the fuel pump timing as required.
Low Compression: Worn piston rings or valves can lead to low compression, causing incomplete combustion. Solution: Perform a compression test to diagnose the issue. Repair or overhaul the engine as needed.
Overloading the Engine: Operating the excavator beyond its capacity can cause the engine to produce black smoke. Solution: Ensure the machine is operated within its recommended limits.
