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 fluid flow. Example: Kawasaki K3V112DT Hydraulic Pump, Part Number: K3V112DT-9C20-9N04.
Travel Final Drive (行走减速机): A gearbox connected to the hydraulic travel motor, reducing the motor's high-speed, low-torque output to the low-speed, high-torque required to drive the machine's tracks or wheels. Installed in the undercarriage. Example: Eaton 78453-1004 Travel Final Drive for Bobcat 331, Part Number: 78453-1004.
Gear Pump (齿轮泵): A type of positive displacement pump that uses meshing gears to pump fluid. Typically installed as a main hydraulic pump or auxiliary pump. Example: Parker PGP511A0400CM1H Gear Pump, Part Number: PGP511A0400CM1H.
Axial Piston Pump (轴向柱塞泵): A type of hydraulic pump that uses reciprocating pistons in a cylindrical array to pump fluid. Often used as the main hydraulic pump in excavators. Example: Rexroth A10VSO28DR/31R-PSC62N00 Axial Piston Pump, Part Number: R902056723.
Radial Piston Pump (径向柱塞泵): A type of hydraulic pump where the pistons move radially outward in a cylinder block. Can be used in various hydraulic applications. Example: Linde HPR105-02M55 Radial Piston Pump, Part Number: 02M55.
Hydraulic Motor (液压马达): A rotary actuator that converts hydraulic power into mechanical power. The travel final drive is connected to the hydraulic motor. Example: Kayaba MAG-18VP-230F Hydraulic Motor, Part Number: MAG-18VP-230F.
Swing Motor (回转马达): A hydraulic motor that powers the rotation of the upper structure of an excavator. Installed in the upper structure. Example: Nabtesco GM35VL Swing Motor for Komatsu PC200-8, Part Number: GM35VL-2.
Control Valve (控制阀): Directs the flow of hydraulic fluid to various actuators in the hydraulic system. Located within the hydraulic system manifold. Example: Sauer-Danfoss PVG 32 Control Valve Section, Part Number: 157B3102.
Pilot Pump (先导泵): A small hydraulic pump that provides the pilot pressure required to operate the main control valve. Usually attached to the main hydraulic pump. Example: Bosch Rexroth AZPN-11-004RRR01MB Pilot Pump, Part Number: AZPN-11-004RRR01MB.
Track Roller Motor (托链轮马达): In some specialized machinery, a hydraulic motor used to drive the track rollers. Installed within the track roller assembly. Example: Doosan DX225LC Track Roller Motor, Part Number: 2705-1026.
Common Questions about Excavator and Mining Equipment Parts:
- What are the common causes of failure in hydraulic pumps in excavators?
- Where can I find reliable suppliers of travel final motor drives for mining equipment?
- How often should I replace the hydraulic oil in my excavator to maintain the longevity of the hydraulic pumps?
Engine Failure and Solution: Overheating Engine
Problem: The engine temperature gauge is reading high, and there might be steam coming from under the hood. The engine may also be losing power or making unusual noises.
Possible Causes and Solutions:
- Low Coolant Level: Check the coolant level in the radiator and the overflow tank. If it's low, add the appropriate type and amount of coolant. Look for leaks in hoses, the radiator, or the water pump.
- Faulty Thermostat: The thermostat regulates the flow of coolant to the engine. If it's stuck closed, the engine can overheat. Replace the thermostat with a new one of the correct temperature rating.
- Malfunctioning Water Pump: The water pump circulates coolant through the engine. If it's not working properly, the engine can overheat. Check for leaks or unusual noises from the water pump. If faulty, replace it.
- Clogged Radiator: A blocked radiator can restrict coolant flow and reduce its ability to dissipate heat. Flush the radiator to remove any debris or scale. If severely clogged, it may need to be professionally cleaned or replaced.
- Loose or Broken Fan Belt: The fan belt drives the cooling fan, which helps to cool the radiator. Inspect the fan belt for cracks, wear, or looseness. Replace or tighten the belt as needed.
- Head Gasket Leak: A blown head gasket can allow combustion gases to enter the cooling system, causing overheating. This is a more serious issue that requires professional repair. Look for bubbles in the coolant or white smoke from the exhaust.
Important Note: If your engine is overheating, stop the vehicle as soon as it is safe to do so and turn off the engine to prevent further damage. Allow the engine to cool down before attempting any repairs.
