4 month ago
Product details
I. Product Positioning and Core Functions
The hydraulic piston pump models2430429/1463685are classified ashigh-pressure axial variable-displacement piston pumps, widely utilized in construction machinery, industrial hydraulic systems, and other fields. Their core function is to pressurize and deliver hydraulic oil through the reciprocating motion of pistons, providing a stable and efficient power source for system operations such as lifting, rotation, and locomotion.

II. Technical Specifications and Performance Characteristics
1. Model Correspondence
• Models 2430429 and 1463685 may represent different identifiers (e.g., part numbers, drawing numbers, or supplier codes) for the same product. Verification with the specific brand is required. For example, Vickers (Eaton) PVB series or CCHC K3V series use similar numbering conventions.
2. Key Technical Parameters
• Displacement Range: Based on model analysis, displacement likely ranges from10–200 cc/rev(e.g., PVB45 offers 45 cc/rev). Specific values require reference to the product manual.
• Rated Pressure: Typically350–420 bar(e.g., Linde HPR-02 series), meeting high-pressure operational demands.
• Speed Range:800–1,300 rpm, supporting continuous high-load operation.
• Control Modes: Supports constant pressure variable displacement, load sensing, constant power, and other modes to adapt to energy-saving requirements under varying loads.
3. Performance Advantages
• Energy Efficiency: Axial variable-displacement design automatically adjusts output based on load, minimizing energy loss.
• Compact Structure: Integrated design ensures small size and lightweight, facilitating easy installation and maintenance.
• Long Service Life: High-strength materials and specialized treatments for critical components (e.g., pistons, bearings) enhance wear resistance.
• Low Noise: Optimized flow path design and balanced components ensure smooth operation with reduced noise.

III. Typical Application Scenarios
1. Construction Machinery
• Used in hydraulic systems of excavators, cranes, and loaders to power primary functions such as digging, lifting, and steering.
• Example: CCHC’s K3V180DTP series pump (180 cc/rev, 35 MPa rated pressure) is employed in excavator main pumps.
2. Industrial Hydraulic Equipment
• Provides high-pressure hydraulic sources for injection molding machines, die-casting machines, and hydraulic presses, ensuring precision and efficiency in molding processes.
• Example: Vickers PVB series pumps stabilize high-pressure oil delivery for mold opening/closing and injection in injection molding machines.
3. Special-Purpose Equipment
• Adapts to high-load, long-duration operations in port machinery (e.g., quay cranes, gantry cranes) and ship steering gear.
• Example: Linde HPR-02 series pumps (400 bar working pressure) ensure responsive steering in marine applications.

IV. Selection and Maintenance Recommendations
1. Selection Guidelines
• Displacement Matching: Choose a displacement aligned with equipment requirements to avoid inefficiency or system overheating.
• Pressure Rating: Ensure the pump’s rated pressure exceeds the system’s maximum operating pressure, with a safety margin.
• Control Mode: Select based on operational conditions (e.g., constant pressure variable displacement for fluctuating loads).
2. Maintenance Practices
• Regular Inspections: Monitor oil cleanliness, temperature, and pressure; replace filters and hydraulic oil as scheduled.
• Component Replacement: Adhere to manual-recommended intervals for replacing seals, bearings, and other wear-prone parts to prevent leaks and wear.
• Fault Diagnosis: Investigate abnormal noise or pressure fluctuations by checking piston, slipper, and port plate wear.
