1.Installation Precautions
Port Cleanliness: Ensure all hydraulic line ports are pristine before connection. Even microscopic contaminants can score the motor’s internal distribution plate.
Priming & Air Bleeding: It is mandatory to pre-fill the motor casing with clean hydraulic oil via the drain port and bleed trapped air before startup to prevent cavitation or “dry-start” seizure.
Balance Verification: Inspect the fan blade’s dynamic balance during assembly. Ensure a secure and concentric connection to avoid premature bearing failure caused by excessive vibration.
2.Maintenance Guidelines
Oil Quality Monitoring: Regularly check hydraulic oil cleanliness. Fluid contamination is the primary cause of reduced motor speed and diminished cooling efficiency.
Leakage Inspection: Monitor the shaft seal for any signs of seepage. Promptly replace seals upon detecting leaks to maintain optimal cooling performance and prevent engine overheating issues.
