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 (hydrostatic energy i.e. pressure and flow). It is installed in the hydraulic system to provide pressurized fluid. Example: Kawasaki K3V112DT Hydraulic Pump, Part Number: 49131-0052
Main Pump (主泵): The primary hydraulic pump in an excavator, responsible for supplying hydraulic power to various actuators. It is typically located near the engine and connected to it via a drive shaft. Example: Hitachi ZX200 Main Hydraulic Pump, Part Number: 9267981
Pilot Pump (先导泵): A small hydraulic pump that provides low-pressure hydraulic oil to control the main hydraulic valves. It is usually mounted on the main pump or the engine. Example: Komatsu PC200 Pilot Pump, Part Number: 708-1F-00011
Gear Pump (齿轮泵): A type of hydraulic pump that uses the meshing of gears to pump fluid by displacement. It can be found in various auxiliary hydraulic circuits. Example: Caterpillar 416E Gear Pump, Part Number: 246-5718
Piston Pump (柱塞泵): A type of hydraulic pump that uses reciprocating pistons to move fluid. Main hydraulic pumps in excavators are often piston pumps. Example: Volvo EC210 Piston Pump, Part Number: VOE14524713
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 excavator's tracks. It is mounted inside the undercarriage, directly connected to the tracks. Example: Hitachi EX60 Travel Final Drive, Part Number: 9147487
Travel Motor (行走马达): A hydraulic motor that provides the rotational power to the travel final drive, enabling the excavator to move. It is bolted directly onto the travel final drive. Example: Komatsu PC300 Travel Motor, Part Number: 706-8G-01041
Swing Motor (回转马达): A hydraulic motor that powers the excavator's upper structure to rotate. It is located on the upper structure and connected to the swing gearbox. Example: Caterpillar 320D Swing Motor, Part Number: 247-8918
Boom Cylinder (动臂油缸): A hydraulic cylinder that controls the lifting and lowering of the excavator's boom. It is attached between the main body and the boom arm. Example: Kobelco SK200 Boom Cylinder, Part Number: LQ10V00015F1
Slew Ring (回转支承): A large bearing that allows the excavator's upper structure to rotate 360 degrees on the undercarriage. It is located between the upper and lower frames. Example: Hyundai R220LC-9 Slew Ring, Part Number: 21EN-1011
Frequently Asked Questions about Engineering Machinery Parts
Q: What are the common signs of a failing hydraulic pump in an excavator?A: Common signs include slow hydraulic operation, overheating hydraulic oil, unusual noises from the pump, and decreased power in hydraulic functions.
Q: How often should the hydraulic oil be changed in mining equipment?A: The hydraulic oil change interval varies depending on the equipment type and operating conditions. Refer to the manufacturer's manual, but generally, it's between 2,000 to 4,000 hours or annually.
Q: What are the main brands you supply for machinery engines?A: We primarily supply machinery engines from brands like KUBOTA, Yanmar, Isuzu, Mitsubishi, and Cummins, suitable for various excavator and agricultural tractor models.
Common Engineering Machinery Engine Fault and Solution
Engine Overheating
Details: Engine overheating is a common problem in construction machinery, especially during heavy operation or in hot weather. It can lead to significant engine damage if not addressed promptly.
Possible Causes:
Low coolant level
Faulty thermostat
Radiator blockage (internal or external)
Water pump failure
Loose or damaged fan belt
Engine overload
Troubleshooting Steps:
Check Coolant Level: Ensure the coolant level in the radiator and expansion tank is within the recommended range. If low, check for leaks.
Inspect Radiator: Clean any external debris from the radiator fins. Check for internal blockages by observing coolant flow (if possible and safe).
Check Thermostat: A faulty thermostat can prevent proper coolant circulation. This often requires professional diagnosis and replacement.
Inspect Water Pump: Look for signs of leakage or unusual noises from the water pump. A failing water pump won't circulate coolant effectively.
Check Fan Belt: Ensure the fan belt is in good condition and has the correct tension to drive the fan and water pump.
Reduce Load: If the engine is consistently overheating under heavy load, try reducing the workload or operating in cooler periods.
Our business scope includes supplying high-quality excavator parts, mining equipment parts, machinery engines, hydraulic pumps, and travel final motor drives. We offer both OEM and aftermarket options, along with comprehensive maintenance and regeneration services for machinery.
