V. Installation & Maintenance
1. Pre-Installation Preparation:
• Ensure the system tank and piping are clean and free of contaminants.
• The pump's inlet must maintain sufficient suction pressure to avoid cavitation and air ingestion.
2. Installation Requirements:
• Use a flexible coupling to prevent stress from misalignment or thrust.
• Maximum allowable misalignment error (TIR) < 0.1mm; maximum allowable angular error < 0.2°.
• The suction port piping diameter must match the pump's specified flange diameter.
• For steel piping at the suction or discharge ports, use rubber hoses to minimize noise from additional loads.
3. Oil Filling & Air Venting:
• Before initial startup, fill the pump with clean hydraulic oil and vent air through the bleed port.
4. Startup:
• Perform a no-load jog operation to confirm correct rotation direction before gradually increasing pressure to the operating level.
5. Pressure Adjustment:
• The set pressure of the FR01C variable mechanism can be adjusted via the regulating screw, within the system's allowable range.
6. Maintenance:
• Regularly check fluid cleanliness (recommended NAS 9 grade or better) and replace filters and hydraulic oil as scheduled.
• Monitor the pump for abnormal noise or temperature changes; stop immediately if detected.
7. Warnings:
• Never operate under overpressure, oil starvation, or severe contamination conditions.
• Fully relieve system pressure before maintenance.
