How to Conduct Preventative Maintenance on a Hydraulic Power Unit

Learn essential tips for maintaining your hydraulic power unit to ensure longevity and performance.

Hydraulic power units are pivotal in powering a vast array of tools across different industries. However, it's widely observed that many of these units suffer from neglect in routine maintenance. Preventative maintenance is critical to extend the operational life of these units, which emphasizes the importance of awareness among unit owners about their maintenance needs. This maintenance can be performed personally or through a professional service.
Preventative maintenance for hydraulic power units involves a series of straightforward tasks adhering to the manufacturer’s guidelines. These tasks are essential for safe operation and long-term functionality.
Key maintenance steps include:
Lubrication of Electric Motors:
Consult the motor's manufacturer or the user manual to understand the specific lubrication needs and frequency for your electric motor. Adhering to these guidelines is crucial to maintain optimal motor condition.
Cleaning or Replacing Filters:
Check the filter's indicator, if available, right after system startup to determine whether it needs cleaning or replacement before machine operation. If your power unit lacks an indicator, the user manual will specify the maintenance frequency. Always use the correct type of filter as recommended by the manufacturer.
Cleaning Suction Strainers:
Initial cleaning should occur after the first 10 hours of operation, followed by routine cleaning every 100 hours. Specific cleaning intervals can vary depending on the unit's manufacturer.
Oil Level Checks in Reservoirs:
Regular checks are necessary to ensure the oil level in the reservoir does not fall below the recommended level, particularly after the initial 100 hours of use.
Oil Changes:
Change the oil as specified by the manufacturer, usually between every 1,000 to 2,000 hours of operation, depending on the unit's usage demands and operating environment.
Monitoring Oil Condition:
Regularly check the oil's condition to ensure it is not overheating, which can be indicated by a darker color or a burnt smell.
By following these steps, owners can maintain the efficacy and extend the life of their hydraulic power units, avoiding costly repairs and downtime.
