Guide to Preventative Maintenance for Hydraulic Power Units

Essential maintenance practices to ensure the reliability and performance of hydraulic power units.

Hydraulic power units are essential components in various industrial settings, providing the necessary energy for countless applications. Despite their ubiquity, many of these units do not receive the required preventative maintenance, which is crucial for their longevity and efficiency. Whether conducted in-house or by professionals, maintaining your hydraulic power unit is imperative.

Preventative maintenance involves a set of basic but essential steps that should be followed according to the manufacturer’s guidelines to ensure safety and efficiency:

Motor Lubrication:

Lubrication is vital for the health of electric motors. The manufacturer will provide specific instructions on how often and how to lubricate the motor to ensure it remains in optimal condition.

Filter Management:

Regular checking and changing of filters are crucial. Use the indicator (if available) to determine when a filter needs attention or consult the maintenance schedule in the user manual for guidance. Always replace filters with the correct type as specified by the manufacturer.

Suction Strainer Cleaning:

Cleaning of suction strainers should be performed after the first 10 hours of operation and then at every 100-hour interval, or as recommended by the manufacturer.

Reservoir Oil Level Checks:

Ensure the oil level in the reservoir is checked regularly, particularly after the initial use period, to maintain proper oil volume.

Oil Replacement:

Change the oil according to the manufacturer's guidelines, typically after every 1,000 to 2,000 hours of operation, depending on environmental and operational conditions.

Oil Condition Monitoring:

Keep an eye on the condition of the oil. Overheating can be identified by changes in oil color to a darker shade or a burnt smell, indicating it's time for a change.

These proactive maintenance steps help avoid downtime and extend the lifespan of hydraulic power units, ensuring they continue to operate effectively.
