Effective Preventative Maintenance for Hydraulic Power Units

Discover how regular preventative maintenance can enhance the efficiency and lifespan of hydraulic power units.

Maintaining hydraulic power units properly is crucial to ensure their longevity and efficient performance. These units, which are integral to a wide range of industrial applications, often fail to receive the necessary preventative maintenance. This maintenance is not only essential but also quite manageable if done according to the manufacturer's recommended practices.

Here are the fundamental tasks involved in the preventative maintenance of a hydraulic power unit:

Lubrication of Electric Motors:

Frequent lubrication based on the guidelines provided by the electric motor manufacturer is necessary. The specific details regarding lubrication intervals and methods can typically be found in the motor's user manual or by contacting the manufacturer directly.

Filter Maintenance:

If your unit is equipped with a filter indicator, inspect it right after starting the unit to decide whether it requires cleaning or replacing. For units without an indicator, refer to the maintenance schedule in the manual. Ensure that any filters used are compatible as specified by the manufacturer.

Suction Strainer Maintenance:

These should be cleaned initially after the first 10 hours of use, with subsequent cleanings every 100 hours or as per the guidelines of the specific machine's manufacturer.

Checking and Maintaining Oil Levels:

Regular checks of the oil reservoir are important to ensure the oil level is adequate, especially during the initial stages of usage. These checks should be a routine part of your maintenance schedule.

Changing the Oil:

Based on manufacturer recommendations, oil should typically be changed every 1,000 to 2,000 hours depending on the usage intensity and environmental conditions.

Monitoring Oil Quality:

Regular inspection of the oil for any signs of overheating, such as a darker color or burnt odor, is critical to prevent damage and ensure smooth operation.

By adhering to these preventative maintenance steps, operators can significantly reduce the risk of unexpected breakdowns and ensure their hydraulic power units perform optimally for a longer period.
