The importance of changing the hydraulic oil in your elevator

Hydraulic oil in an elevator is a specialized fluid used to transmit power within the elevator's hydraulic system.

It acts as a lubricant for the system's components, such as the pump and cylinders, and helps to create the hydraulic pressure needed to move the elevator car up and down smoothly. The oil also absorbs heat generated during operation, preventing overheating and ensuring efficient performance.

Hydraulic oil does need to be changed they say every 1-3 years but it does depend on the manufacturer’s recommendation. Regular inspections and monitoring the condition of the oil which is done by trained service technicians will also help determine if an earlier change is needed.

Here are 5 reasons why you need to change the oil:

Maintain Efficiency

Over time, hydraulic oil can become contaminated with debris, moisture, and metal particles from the system's components. This contamination can reduce the oil’s ability to lubricate and maintain hydraulic pressure, leading to inefficient operation and increased energy consumption.

Prevent Wear and Tear:

Fresh hydraulic oil helps to keep the internal parts of the elevator's hydraulic system – such as the pump, cylinders, and seals—well-lubricated. This reduces friction and wear, which can extend the lifespan of these components and prevent costly repairs.

Avoid Corrosion:

Contaminated oil can cause rust and corrosion on metal parts. Changing the oil regularly helps to prevent this and keeps the hydraulic system in good condition.

Ensure Safety:

An elevator is a critical safety system, and hydraulic failures can lead to malfunctions or accidents. Regular maintenance, including changing the hydraulic oil, helps to ensure that the elevator operates safely and reliably.

Maintain Warranty:

Many elevator manufacturers require regular maintenance, including oil changes, to keep the warranty valid. Neglecting this can potentially void any warranty coverage.

There are of course cons to if you decide to not change the hydraulic oil:

System Failure:

Contaminated oil can cause the hydraulic system to fail, leading to potential breakdowns or malfunctions that could compromise safety.

Increased Wear:

Old oil can cause excessive wear on hydraulic components, leading to expensive repairs and replacements.

Reduced Efficiency:

The elevator might operate less smoothly and more slowly, causing inconvenience and potential operational issues.

Safety Risks:

Hydraulic failures can result in unexpected stops or uncontrolled movements, which pose safety risks for passengers.

Corrosion:

Contaminated oil can cause rust and damage to metal parts, worsening over time and leading to severe damage.

In conclusion, it is better to change your oil as per the manufacturers or the trained technicians’ recommendations to avoid the possible danger of not changing it.
