3. Structural & Functional Features
• Swashplate Axial Piston Design:
• 9 evenly distributed pistons adjust displacement via swashplate angle, achieving >92% efficiency.
• Built-in pressure compensation valve for variable control (e.g., load-sensing systems).
• Negative Flow Control (NTC):
• Automatically adjusts displacement by detecting pump outlet flow feedback to reduce energy loss.
• High-Pressure Self-Sealing Technology:
• Piston heads use composite material seal rings that expand under high pressure to prevent leakage.
• Modular Interfaces:
• Supports SAE, BSPP, DIN, and other port standards for global hydraulic system compatibility.
------
4. Typical Applications
• Construction Machinery:
• Primary hydraulic pump for excavators (e.g., SANY SY215C-9T46 models), cranes, and road rollers.
• Example: Drives travel, swing, and boom motions in SY215C excavators.
• Industrial Equipment:
• Hydraulic power source for injection molding machines and metal die-casting machines.
• Marine & Offshore Engineering:
• Hydraulic drive for deck machinery (winches, anchor windlasses).
------
5. Maintenance & Troubleshooting
Daily Inspections:
• Fluid cleanliness: Must meet NAS 6 or ISO 18/15 standards.
• Temperature monitoring: Oil temp >85°C requires cooling system check.
• Leakage inspection: Focus on piston chambers and port seals.
Common Faults & Solutions:
【表格】
Symptom Possible Cause Solution
Insufficient flow Stuck swashplate, clogged suction line Clean swashplate control valve, replace suction filter
Pressure fluctuations Air ingestion, faulty relief valve Perform air bleeding, calibrate relief valve setting
Abnormal noise Worn pistons, damaged bearings Replace piston set, inspect main shaft bearings
Oil emulsification Condensation ingress, seal failure Replace breather valve, check oil seals
Spare Parts List(Example):
• Piston Set (Part No.: K5V-160-PLUNGER)
• Swashplate Control Valve (Part No.: K5V-160-VALVE)
• Seal Kit (Part No.: K5V-160-SEAL)
------
6. Certifications & Standards
• Compliance: ISO 4413, DIN 24333, GB/T 7935
• Certifications: CE (EU Safety), RoHS (Environmental), ATEX (Explosion-proof optional)
