Hydraulic lift problem - hot hydraulic fluid

Click For Summary
SUMMARY

The discussion centers on a hydraulic lift system struggling with overheating hydraulic fluid when lifting loads exceeding 1 tonne. The user increased the flow rate to mitigate the issue, but this adjustment exceeds the system's permitted flow rate, raising concerns about potential damage. Recommendations include cooling the hydraulic fluid and reducing the hoist speed to alleviate pump overload, which may improve performance without risking system integrity.

PREREQUISITES
  • Understanding of hydraulic systems and their components
  • Knowledge of hydraulic fluid properties and cooling techniques
  • Familiarity with flow rate calculations and limitations
  • Experience with pump performance and load management
NEXT STEPS
  • Research hydraulic fluid cooling methods and systems
  • Learn about flow rate optimization in hydraulic systems
  • Investigate pump overload causes and solutions
  • Explore techniques for adjusting hoist speed without compromising performance
USEFUL FOR

Hydraulic engineers, maintenance technicians, and anyone involved in the design or operation of hydraulic lift systems facing overheating issues.

I have hydraulic system that lift something heavier than 1 tonne. My problem is the hydraulic fluid always get so hot and sometimes because of the heat it could not lift its load (loss power). I tried to increase its flow rate and its worked for now. But it way above the permitted flow rate. I am scared that what I've done could damage the system in future. What should I do?

Can you cool the fluid in your system?
Alternatively, it may be that your pump is overloaded. Maybe if you reduced the hoist speed your pump would cope better.
