FAQ:
Flow instability, often accompanied by pressure fluctuations, is frequently related to issues within the control piston mechanism. This can be due to contamination scratching the control piston, a weak or damaged control amplifier spring, or other damaged components. Addressing this usually requires disassembling the pump to inspect, repair, or replace the affected parts, and possibly increasing damping or spring stiffness.
Q12: The pump is leaking oil externally. Where should I look?
External leaks can originate from:
• Shaft Seal: Damaged or worn-out shaft seal.
• Pipe Connections: Loose hose connections, damaged fittings, or aged/ cracked sealing washers.
• Case Ports: Leaks from the variable mechanism cover bolts due to loose bolts or破损 seals.
• Case Imperfections: Rarely, sand holes in cast iron casings or poor welds.
• High Case Pressure: Excessive internal leakage can pressurize the case, damaging seals or pushing them out. Ensure the case drain line is unrestricted, of adequate size, and not too long.
5. Special Topics & Long-Term Storage
Q13: When is bearing flushing necessary, and what is the flow rate?
Bearing flushing is recommended for: using special HF fluids, operating at viscosity/temperature limits, or for pumps installed vertically (shaft up). Refer to technical documentation for specific flow rates, which range from ~3 L/min for size 40 to ~40 L/min for size 1000.
Q14: How should I handle the pump for long-term storage?
If the pump is to be stored for an extended period:
• Drain all hydraulic fluid from the pump casing.
• Perform a thorough cleaning and drying.
• Apply a rust preventive agent.
• Store in a dry, ventilated place.
• Before putting back into service, perform a comprehensive inspection and maintenance check.
