What is the difference between hydraulic oil and engine oil?
There are different types of oils available on the market for various equipment. If you are a novice and learn hydraulic oil and engine oil, you will find that their differences and uses confuse you, so this article is for you. We will provide you with a simple differentiation breakdown, if one can replace the other.
If you are just beginning to understand the difference between the three, or you are refreshing your memory before starting to use equipment oil, you have read the correct article.
Hydraulic oil
Hydraulic oil is the energy transmission medium in all hydraulic systems. They contain a variety of compounds. This includes oil, butanol, phthalate, adipate, polyalkylene glycol, corrosion inhibitor, anti-corrosion additive, etc. The main purpose of hydraulic oil is to transfer hydraulic energy, but it can also be used for auxiliary functions. These secondary functions can be heat transfer, contaminant removal, sealing, and lubrication.
The hydraulic equipment needs lubrication to prevent internal parts from wearing and melting. Hydraulic oil provides adequate lubrication between moving parts. Without the lubrication characteristics of hydraulic oil, these systems will be very inefficient and unreliable.
In order for the hydraulic oil to work, the following specific characteristics must be met:
Viscosity – protects the oil from damage that can cause cavitation
Viscosity Index – measures viscosity from one temperature to another
Wear Inhibitor – Extends equipment life by reducing wear
Engine oil
Oil is a mixture of base oil and additives used to lubricate engine parts, reduce friction and protect the engine. Engine oil consists of base oil and additives. Base oil accounts for 70-90% of the total, and is produced by natural gas or crude oil. At the same time, the additives supplement the remaining 10-30%, which can be the following:
1. Dispersant – helps protect engine performance
2. Detergent - prevent sediment
3. Anti foam additive - to prevent problems under high temperature
4. Corrosion inhibitor - preventing acid from reacting with metal
And more
What is the difference between hydraulic oil and motor oil?
Hydraulic oil and motor oil are made of base oil mixed with additives. Hydraulic oils are expected to have low compressibility, predictable friction and viscosity stability. Engine oil has high heat resistance and resistance to absorption of fuels and chemical compounds generated during combustion.
