How is hydraulic fluid maintained in elevators?

Maintaining hydraulic fluid in elevators is crucial for their safe and efficient operation, especially as it plays a significant role in the transfer of power within the hydraulic system. Regular checking and replacement are essential practices because hydraulic fluid can degrade over time due to exposure to heat, contaminants, and oxidation. By routinely checking the fluid level and its condition, technicians ensure it remains effective in lubricating and sealing the hydraulic components, ultimately extending the life of the system and preventing malfunctions.

Additionally, replacing hydraulic fluid at intervals recommended by manufacturers or based on the condition of the fluid helps prevent issues such as pump wear, system overheating, and operational inefficiency. This proactive maintenance approach ensures that the hydraulic system functions smoothly, reducing the likelihood of breakdowns and enhancing the overall reliability of the elevator.
