III. Application Fields
The K3VL series pumps are widely used in various scenarios requiring medium- and high-pressure hydraulic power, including but not limited to:
1. Construction Machinery: Such as excavators, loaders, and cranes, providing stable and reliable hydraulic power for these equipment.
2. Industrial Equipment: In machine tools, plastic processing machinery, metallurgical equipment, and other fields, the K3VL series pumps also play an important role.
3. Agricultural Machinery: Providing hydraulic power for tractors, harvesters, and other agricultural machinery to enhance operational efficiency.
IV. Technical Advantages
1. Load Sensing Control: Through built-in pressure compensators, load-independent flow control is achieved, ensuring stable operating speeds for machines under different loads.
2. Torque Limiting Function: When the pressure in the pump output circuit becomes excessively high, the main relief valve on the main control valve will relieve pressure, preventing overload of the pump circuit and protecting the pump and system safety.
3. Electronic Displacement Control: Supports electronic displacement control, allowing precise adjustment of pump displacement based on actual needs, improving system flexibility and efficiency.
V. Selection and Usage Recommendations
1. Select the Appropriate Model Based on Needs: Choose the suitable K3VL series pump model according to the required flow rate and pressure.
2. Pay Attention to Installation and Commissioning: During installation and commissioning, strictly follow the product manual to ensure normal pump operation.
3. Regular Maintenance and Upkeep: Regularly maintain and upkeep the pump, checking oil performance, cleaning oil filters, etc., to extend the pump's service life.
