Key Points for Hydraulic Cylinder Maintenance
1.Keep Hydraulic Oil Clean
a.Contaminated oil is a major cause of hydraulic failure.
b.Use high-efficiency filters and replace them regularly.
c.Install differential pressure gauges to monitor filter condition.
d.Clean the oil immediately if contamination is detected.
2.Perform Regular Maintenance
a.Inspect the cylinder rod for corrosion, wear, or pitting.
b.Prevent water contamination—it leads to seal damage and failure.
c.Check for misalignment, which causes uneven wear and premature damage.
d.Re-chrome or polish damaged rods; replace if necessary and address root causes.
3.Rotate or Alternate Cylinders
a.Use spare or alternate cylinders to reduce wear and minimize downtime.
b.Service removed cylinders before reuse.
c.Replace seals and inspect for system-wide issues (e.g., excessive varnish from high oil temperature).
4.Maintain Cylinder Accessories
a.Check pivot pins, clevises, and other joints for wear or damage.
b.Worn components can cause misalignment and lead to further damage.
c.Timely replacement of accessories ensures optimal cylinder performance.
