Maintenance action plan
Follow up a maintenance action plan to avoid failure of hydraulic equipment.
Causes of hydraulic system breakdowns are:
- Overheating in hydraulic system. Hydraulic system are subject to a rise in temperature during operation. Oil within 40⁰C and 50⁰C has good flow characteristics. Extremes of temperature make the oil inefficient. Oil at low temperature it becomes thicker and sluggish and at high temperature it becomes thinner and is less lubricant leading to increase of wear of parts and a reduction in seal life.
- Excessive oil pressure. Viscosity is affected by system pressure. An increased in system pressure increases the viscosity of oil. Viscosity can affect heat generation and lubrication process.
- Interfering of unskilled labor with Hydraulic. Hydraulic system intervention required skill personnel.
Records should be kept of past failures and the action initiated along with data containing details such as oil tests, oil changes, filter replacements, etc.
Basic maintenance action plan:
- Using common sense for a good maintenance. Think before act is the most important step but the one most overlooked.
- When talking about Hydraulic always try to work in a clean environment.
- Check manual, instruction, procedure, recommendation and drawings of hydraulic equipment manufactures.
Important Hydraulic system checks:
• Check the hydraulic system for leakage. A leaking pipe can also allow air and dirt to enter in the system. Tighten the screws, replace faulty seals and keep the drive clean.
• Clean oil and inspect magnetic filters. Replace the required clogged filter cartridges, inspect the tank and clean if necessary.
• During inspection pay attention to dirt or other contaminations that can affect the hydraulic system.
• To be kept a running log or chart and planned inspection to be carried out at set intervals.
