I. Compatible Model and Application
• Compatible Model: Caterpillar CAT374 Hydraulic Excavator.
• Application: As the core component of the hydraulic system, the K7V280DTP hydraulic pump is responsible for providing high-pressure hydraulic oil to various actuators of the excavator (such as the boom, arm, bucket, and swing mechanism) to achieve digging, loading, swinging, and other actions.
II. Technical Characteristics (Inferred Based on the Hydraulic System Characteristics of CAT374 Excavator)
• Flow Rate and Pressure:
• Flow Rate: The main pump design of the CAT374 excavator's hydraulic system must meet its high-flow requirements to support compound actions (such as simultaneous swinging and digging). Although the specific flow rate value needs to be referenced from the model specification sheet of the K7V280DTP, it generally reaches several hundred liters per minute.
• Pressure: The rated pressure of the CAT374 excavator's hydraulic system is typically high to cope with heavy-duty digging and breaking operations. The K7V280DTP hydraulic pump must be able to provide sufficient pressure, generally reaching 350 bar or higher.
• Structure and Materials:
• Structure: The K7V280DTP hydraulic pump may adopt a swashplate axial piston pump design, which offers advantages such as high volumetric efficiency and low pressure fluctuations.
• Materials: Key components such as the pump body, pistons, and port plate may be manufactured from high-strength, wear-resistant materials to ensure reliability and durability under harsh operating conditions.
• Control Method:
• The K7V280DTP hydraulic pump may employ electro-hydraulic proportional control or load-sensing control methods to achieve precise flow and pressure regulation, enhancing the excavator's operational performance and fuel economy.
III. Performance Advantages (Inferred Based on the Performance of CAT374 Excavator)
• Efficiency and Energy Saving: The K7V280DTP hydraulic pump may incorporate advanced hydraulic technologies and materials to improve volumetric and mechanical efficiency, reducing energy consumption.
• Reliability and Durability: Caterpillar products are renowned for their reliability and durability. The K7V280DTP hydraulic pump may undergo rigorous quality control and durability testing to ensure long-term stable operation under harsh conditions.
• Easy Maintenance: The K7V280DTP hydraulic pump may be designed with easily removable and replaceable components, as well as convenient maintenance interfaces, to reduce maintenance costs and downtime.
