FAQ:

Q7: Why does my pump get overheated?

Common causes for excessive heating include:

• Internal Leakage: Excessive internal leakage within the pump components converts hydraulic energy to heat.

• Mechanical Friction: Dry or semi-dry friction due to worn parts or inadequate lubrication generates heat.

• Fluid Friction: Inadequate tank capacity or cooling, causing the system to overheat.

• Clogged Return Line Filter: A blocked return filter creates high backpressure, leading to increased temperature.

• Low Oil Level: Insufficient oil in the reservoir reduces cooling capacity.

4. Maintenance & Troubleshooting

Q8: What does daily/regular maintenance involve?

• Keep the pump exterior clean from dust and oil污.

• Check oil levels before start-up and during operation.

• Listen for abnormal noises during operation, which may indicate internal issues like part wear or looseness.

• Regularly record operating parameters like pressure, flow, and temperature to monitor health.

• Change fluid filters periodically (e.g., every 1000 hours or as per conditions).

• Check and replace worn or aged seals.

• Follow lubrication requirements for various points.

• Inspect the coupling for looseness or wear.

Q9: The pump outputs insufficient flow or no flow at all. What could be wrong?
