10 Jan 2023, 14:31 GMT+10

Do you ever find yourself feeling in a pickle, trying to figure out what type of oil your hydraulic system needs? Don't worry; we've all been there. Let me help clear up the confusion for you- understanding and selecting the proper hydraulic oil doesn't need to be hard!

In this post, I'm going to give you the low-down on all things related to hydraulic oils - so join me as I walk through an introduction to these mysterious liquids!

What is hydraulic oil?

Hydraulic oil is a liquid form of lubrication commonly found in machines used in industrial applications. It provides lubrication during motion between two parts, reducing friction and heat buildup, which may cause wear and tear on the equipment.

Hydraulic oils are specially formulated to resist breakdown due to high temperature, pressure, shock loads, and chemicals. They contain additives like detergents, anti-oxidants, anti-wear agents, and corrosion inhibitors to provide superior performance above standard motor oils. Hydraulic oil is extremely important as it helps keep operations running safely and efficiently without unexpected shutdowns or costly repairs.

Different types of hydraulic oil?

Several different types of hydraulic oils vary based on the viscosity or thickness within the oil itself, as each type of oil performs a specific task in optimal temperatures and environments. The most common types are mineral-based oils, synthetic blend-based oils, and fully-synthetic oils; however, other specialty fluids may also be suitable depending on your needs.

All hydraulic oil must meet certain requirements assigned by their respective manufacturers in order to function properly and avoid any legal ramifications from improper use or disposal. Therefore, it is important to research which type of hydraulic oil is best for your application before making a purchase or using it on any machinery.

How to identify and select hydraulic oil?

Choosing the right hydraulic oil is essential to maintaining your equipment, keeping breakdowns to a minimum, and improving its performance. To find the proper lubricant for the job, you should research the specification of your piece of machinery so that you can accurately match its requirements. This means having in-depth knowledge of viscosity index, flash/fire point, and pour point, amongst other characteristics of fluid power systems.

Having access to technical information also ensures compatibility with seals and o-rings, as well as establishing any restrictions on the type or brand of oil allowed by certain machines. Once you have identified the compatible lubricants based on these criteria, it is important to consider features such as oxidation resistance, biodegradability, and energy efficiency. It is advisable to consult a hydraulic expert if you are unsure about your selection in order to ensure optimal performance and longer-lasting protection.

The conclusion

Hydraulic oil is an essential component of any hydraulic system. It helps move mechanical operations and provide lubrication to your equipment. When selecting hydraulic oil, it is important to research which type of oil meets the specifications of your machinery and also has the desired features such as energy efficiency, oxidation resistance, and biodegradability.

It is always wise to consult a hydraulic expert if you are unsure about which oil to choose in order to ensure optimal performance and longer-lasting protection. With all of the information provided here, you are now armed with the knowledge to make an informed decision.
