Regarding the K5V140DT-1E05 hydraulic pump model, it is specifically designed as the main hydraulic pump for the EC250D excavator. Here's a detailed breakdown of this hydraulic pump:
Basic Information
Model: K5V140DT-1E05
Applicable Equipment: EC250D Excavator
Type: Main Hydraulic Pump
Product Features
High Performance: As the main hydraulic pump for the EC250D excavator, the K5V140DT-1E05 excels in meeting the hydraulic demands of the excavator under various operating conditions.
Durability: Crafted with high-quality materials and advanced manufacturing techniques, this hydraulic pump ensures a long service life and stable performance.
Load-Sensing Capability: Featuring load-sensing and pressure stabilization, the Kawasaki hydraulic pump adjusts its output pressure and flow rate according to the actual load, thereby enhancing energy efficiency.
Stable Pressure Output: Throughout its operation, the pump maintains a consistent pressure output, ensuring the smooth functioning of all excavator functions.
Working Principle
The K5V140DT-1E05 hydraulic pump belongs to the piston pump category, utilizing hydraulic drive to achieve the suction and discharge of oil. Its working principle involves:
Suction Phase: As the pump rotates, it draws oil from the tank through the suction pipeline.
Discharge Phase: The oil is compressed within the pump and then discharged through the delivery pipeline to various hydraulic actuators in the excavator.
Operation and Maintenance
Pre-Start Preparation: Before starting the hydraulic pump, ensure that the oil flow direction and sound are normal, and let the pump run at low pressure for a while to warm up.
Oil Requirements: The oil must be clean and free of impurities, with a viscosity that meets the pump's operational requirements. Maintain oil temperature within the optimal range to prevent overheating or undercooling from affecting pump performance.
Regular Checks: Perform regular inspections and maintenance on the hydraulic pump, including checking oil levels, oil quality, wear of seals, and promptly replacing damaged components.
Avoid Overload: Prevent the hydraulic pump from operating in an overloaded state for extended periods to avoid damage.
