Best practices for hydraulic system maintenance include:
- Adherence to manufacturer guidelines: Follow the manufacturer's maintenance recommendations and schedules for specific components and the system as a whole
- Employee training: Train personnel in proper maintenance procedures and provide them with the knowledge to identify and address potential issues
- Record keeping: Maintain detailed records of maintenance activities, including fluid changes, component replacements, and any repairs performed
- Scheduled inspections: Implement a regular inspection schedule to proactively identify and address potential problems before they escalate
Preventative maintenance is another form of maintenance best practice for hydraulic systems. Preventative maintenance maintains hydraulic machinery according to a strict schedule and a hydraulic system risk assessment. This also includes following maintenance instructions from the manufacturer of the hydraulic equipment. Maintenance should be carried out frequently, and each maintenance task should be readily understood by all technicians.
An example of a preventative maintenance task might be cleaning the inside and outside of a hydraulic reservoir, or checking tubes, hoses and pumps for wear and tear as part of a hydraulic hose management system. Carrying out preventative maintenance effectively should be enough to eliminate the majority of failures of hydraulic systems.
Predictive maintenance is also beneficial for hydraulics and provides a way of preventing problems growing in hydraulic systems. Condition-monitoring technologies such as vibration monitoring and thermography can be used to help identify faults before they become serious. The engineer can then intervene to fix the issue. Other networks of sensors can also monitor the cleanliness of oil and the level of oil in the hydraulic machinery reservoir, along with fluid temperatures and pressures. Understanding these parameters enables maintenance teams to make changes early on and at minimum expense.
Both preventative maintenance and predictive maintenance are superior to reactive maintenance – waiting for hydraulic machinery to fail and then fixing it, often at great expense and with lost productivity and efficiency.
Some useful troubleshooting techniques for hydraulic system maintenance include:
- Identifying and addressing leaks: Trace and repair hydraulic fluid leaks promptly to prevent damage and maintain system integrity
- Noise analysis: Investigate and address unusual noises as they can indicate issues such as cavitation, air ingestion, or component wear
- Vibration analysis: Monitor vibrations to detect problems with pumps, motors, or other components. Take corrective actions if required
- Pressure and flow testing: Regularly test pressure and flow rates to ensure they align with system specifications. Make adjustments if necessary
Maintaining hydraulic fittings and tubing can often be achieved by simple actions such as cleaning or checking oil or the level of fluid in the machinery reservoir. Carry out these maintenance basics, and enjoy the benefits of improved performance and longer machinery and component lifespan.
Regular and proactive hydraulic system maintenance is crucial for longevity, reliability, and optimal performance. By adhering to preventative maintenance techniques, troubleshooting effectively, and implementing best practices, businesses can minimise downtime, reduce costs, and maximise hydraulic system lifespan.
