Product details
K3V180-DTP Hydraulic Piston Pump Product Overview
TheK3V180-DTPis a high-performance axial piston variable-displacement pump designed for medium- to high-pressure hydraulic systems. It is widely used in construction machinery, industrial equipment, and marine applications. Its core advantages include high efficiency, low noise, long service life, and adaptability to harsh operating conditions, making it ideal for applications requiring continuous high-pressure output and precise flow control.

Key Design Features
1. Axial Piston Variable-Displacement Structure
• Achieves stepless flow adjustment via swashplate angle variation (displacement range: 180 cm³/rev).
• Precision-matched pistons and cylinder blocks minimize leakage, with volumetric efficiency up to92%–95%.
2. High-Pressure Durability
• Rated pressure:35 MPa (5,075 psi); peak pressure up to40 MPa (5,800 psi).
• Suitable for hydraulic breakers, injection molding machines, and other high-pressure systems.
3. Wear-Resistant Materials & Surface Treatments
• Pistons, cylinder blocks, and port plates usehigh-strength alloy steelwith quenching + nitriding (hardness HRC58–62) for exceptional wear resistance.
• Seals (fluororubber/PTFE) operate in temperatures ranging from-30°C to +120°C, compatible with mineral oils and some eco-friendly hydraulic fluids.
4. Low Noise & Vibration
• Optimized flow paths reduce hydraulic shock, while precision bearings minimize mechanical vibration (operating noise ≤78 dB(A)).
5. Modular Design
• Independent replacement of pump body, drive shaft, and control valves reduces maintenance costs by30%.

Selection & Configuration Guide
1. Pressure Matching
• Ensure system operating pressure does not exceed the pump’s rated pressure (35 MPa). Reserve a10% safety margin.
2. Speed & Flow
• Select speed based on load:
• Heavy-duty: 600–1,200 rpm (stable low-speed operation).
• Light-duty: 1,500–2,000 rpm (efficient high-speed operation).
3. Fluid Compatibility
• Standard hydraulic oil: Use standard seals.
• Fire-resistant fluids (HFA/HFB): Replace seals with special materials.
4. Cooling Requirements
• For continuous operation, install air or water cooling to prevent overheating (recommended oil temperature ≤85°C).
------
Maintenance & Troubleshooting
1. Daily Inspections
• Oil level: Maintain reservoir at 1/2–2/3 capacity.
• Temperature: Monitor for abnormal heating (indicates internal leakage or cooling failure).
2. Periodic Replacements
• Hydraulic oil: Replace every 2,000 operating hours or annually (adjust based on conditions).
• Filters: Replace every 500 hours to prevent contaminant ingress.
3. Common Faults
• Insufficient Flow: Check suction line blockage or internal leakage.
• Pressure Fluctuations: Adjust relief valve or inspect stuck safety valves.
• Abnormal Noise: Tighten couplings or replace worn bearings.
