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.
Gear pumps are widely used in excavators due to their reliability and efficiency. Key applications include:
Supplies pressurized oil to hydraulic cylinders for boom, arm, and bucket movements.
Powers the excavator’s rotation by driving the swing motor.
Provides hydraulic pressure for track or wheel movement.
Operates attachments like breakers, grapples, and augers.
Despite their robustness, gear pumps may experience failures due to wear, contamination, or improper maintenance. Common issues include:
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.
Causes: Excessive load, low fluid levels, or degraded oil.
Solutions: Ensure proper oil viscosity, maintain correct fluid levels, and avoid overloading.
Causes: Cavitation, misalignment, or bearing wear.
Solutions: Check suction lines for restrictions, realign pump shafts, and replace worn bearings.
Causes: Damaged shaft seals or worn housing.
Solutions: Replace seals and inspect the pump casing for cracks.
