Excavator gear pump K3V63 DH130 DH150 716654A 719211 for doosan excavator

The gear pump is a critical hydraulic component in excavators, responsible for converting mechanical energy into hydraulic energy by generating fluid flow and pressure. It plays a vital role in ensuring the smooth operation of hydraulic systems in construction machinery. This article provides a comprehensive overview of excavator gear pumps, including their working principle, construction, functions, applications, and maintenance procedures.

  • Product Name: Hydraulic Gear Pump
  • Port: Huangpu
  • Standard: Standard
  • Model:K3V63
  • Part number:716654A 719211
  • Weight: 32 Kgs

Applications of Gear Pumps in Excavators

Gear pumps are widely used in excavators due to their reliability and efficiency. Key applications include:

5.1 Hydraulic System Power Source

  • Supplies pressurized oil to hydraulic cylinders for boom, arm, and bucket movements.

5.2 Swing Mechanism

  • Powers the excavator’s rotation by driving the swing motor.

5.3 Travel Motors

  • Provides hydraulic pressure for track or wheel movement.

5.4 Auxiliary Hydraulic Functions

  • Operates attachments like breakers, grapples, and augers.

Common Failures & Troubleshooting

Despite their robustness, gear pumps may experience failures due to wear, contamination, or improper maintenance. Common issues include:

6.1 Low Pressure or Flow

  • Causes: Worn gears, internal leakage, clogged filters, or air ingress.

  • Solutions: Inspect and replace damaged gears, check for leaks, clean/replace filters, and bleed air from the system.

6.2 Overheating

  • Causes: Excessive load, low fluid levels, or degraded oil.

  • Solutions: Ensure proper oil viscosity, maintain correct fluid levels, and avoid overloading.

6.3 Excessive Noise & Vibration

  • Causes: Cavitation, misalignment, or bearing wear.

  • Solutions: Check suction lines for restrictions, realign pump shafts, and replace worn bearings.

6.4 Fluid Leakage

  • Causes: Damaged shaft seals or worn housing.

  • Solutions: Replace seals and inspect the pump casing for cracks.
