K3V280 Hydraulic Pump Parts (Applicable to Volvo 700 and Volvo 750 Excavators):
1. Piston Shoes:
• Piston shoes are key components that come into contact with the swashplate in the hydraulic pump, responsible for converting hydraulic energy into mechanical energy to drive the pistons in reciprocating motion.
• The quality of piston shoes in the K3V280 hydraulic pump directly affects the performance and lifespan of the pump.
2. Cylinder Block:
• The cylinder block is one of the core components of the hydraulic pump, housing multiple piston bores for installing the pistons.
• The material and machining precision of the cylinder block significantly impact the efficiency and durability of the hydraulic pump.
3. Valve Plate:
• The valve plate is responsible for distributing hydraulic oil to the correct oil passages, ensuring the normal operation of the hydraulic pump.
• In the K3V280 hydraulic pump, the design and manufacturing precision of the valve plate are crucial for pump performance.
4. Thrust Plate:
• The thrust plate is used to withstand axial forces and prevent axial movement of the cylinder block.
• It plays an important role in maintaining the stability of the hydraulic pump and reducing wear.
5. Drift Shaft:
• The drift shaft is the component that transmits power within the hydraulic pump, connecting the motor or engine to the pump.
• In the K3V280 hydraulic pump, the drift shaft needs to withstand high torque and rotational speeds, thus requiring high material quality and manufacturing processes.
Part Application and Compatibility:
• The K3V280 hydraulic pump, a high-performance axial piston pump from Kawasaki, is widely used in large excavators such as the Volvo 700 and 750.
• This series of hydraulic pumps features a dual variable pump design to achieve efficient power output, meeting the heavy-duty operational requirements of Volvo excavators.
• The parts are designed with high-precision fits for the pump body, ensuring stable performance under high-pressure operating conditions.
