Glossary of Engineering Machinery Hydraulic Pumps and Travel Final Motor Drives

Hydraulic Main Pump (液压主泵): The core component of the hydraulic system, converting mechanical power into hydraulic power. It is typically installed in the engine compartment and connected to the engine via a drive shaft. Example: Hitachi ZX200-3 Excavator, Hydraulic Main Pump, Part Number: 9264628

Hydraulic Pilot Pump (液压先导泵): A small pump that provides hydraulic pressure to control the main hydraulic valves. It is usually mounted on the main hydraulic pump. Example: Komatsu PC200-8 Excavator, Hydraulic Pilot Pump, Part Number: 702-16-03071

Travel Motor (行走马达): A hydraulic motor that drives the machine's tracks or wheels, enabling movement. It is located within the undercarriage, directly connected to the final drive. Example: Caterpillar 320D Excavator, Travel Motor, Part Number: 247-8928

Swing Motor (回转马达): A hydraulic motor responsible for rotating the machine's upper structure (house). It is typically mounted on the upper structure and connected to the swing reduction gearbox. Example: Kobelco SK200-8 Excavator, Swing Motor, Part Number: YN24V00017F1

Hydraulic Control Valve (液压控制阀): Directs the flow of hydraulic fluid to various actuators (cylinders, motors) to control machine functions. It is usually located centrally in the hydraulic system. Example: Doosan DX225LC-5 Excavator, Hydraulic Control Valve, Part Number: 2401-9255

Boom Cylinder (动臂油缸): A hydraulic cylinder that raises and lowers the machine's boom. It is connected between the main frame and the boom. Example: Volvo EC210BLC Excavator, Boom Cylinder, Part Number: VOE14527813

Arm Cylinder (斗杆油缸): A hydraulic cylinder that controls the movement of the machine's arm (dipper stick). It is connected between the boom and the arm. Example: Hyundai R220LC-9 Excavator, Arm Cylinder, Part Number: 31Q7-10130

Bucket Cylinder (铲斗油缸): A hydraulic cylinder that controls the tilting and dumping of the machine's bucket. It is connected between the arm and the bucket linkage. Example: Sany SY215C Excavator, Bucket Cylinder, Part Number: 12564783

Final Drive (行走减速器): A reduction gearbox connected to the travel motor that provides the final speed and torque to the tracks or wheels. It is located within the undercarriage. Example: Kubota KX080-3 Excavator, Final Drive, Part Number: RC501-17112

Slew Ring Bearing (回转支承): A large bearing that allows the upper structure of the excavator to rotate 360 degrees on the undercarriage. It is located between the upper and lower frames. Example: Liebherr R914 Compact Excavator, Slew Ring Bearing, Part Number: 10035777

Engine Troubleshooting: Excessive Black Smoke

Problem: Excessive Black Smoke from Engine Exhaust

Description: The engine is emitting a large amount of black smoke from the exhaust pipe, especially during acceleration or under heavy load. This indicates incomplete combustion of fuel.

Possible Causes:

Dirty or clogged air filter: Restricts airflow to the engine, leading to a rich fuel mixture.
Faulty or dirty fuel injectors: Can cause improper fuel atomization and injection timing.
Incorrect fuel injection timing: If the fuel is injected too late, it may not burn completely.
Low engine compression: Worn piston rings or valves can lead to poor combustion.
Overloading the engine: Exceeding the engine's power capacity can result in incomplete burning of fuel.
Using low-quality or incorrect fuel.

Troubleshooting Steps and Solutions:

Check the air filter: Inspect the air filter for dirt and debris. Clean or replace it if necessary. A clogged air filter is a common cause of black smoke.
Inspect fuel injectors: If possible, have the fuel injectors inspected and cleaned or replaced by a qualified technician. Faulty injectors can significantly affect combustion.
Verify fuel injection timing: Ensure the fuel injection timing is set correctly according to the engine manufacturer's specifications. This usually requires specialized tools and knowledge.
Check engine compression: A compression test can reveal if there are issues with piston rings or valves. Low compression often requires engine overhaul.
Reduce engine load: Avoid overloading the engine. Operate within the recommended power limits.
Use the correct fuel: Ensure that you are using the fuel type recommended by the engine manufacturer.

Note: If the problem persists after performing these checks, it is recommended to consult a qualified mechanic for further diagnosis and repair.
