05 Jun Properties that Make Hydraulic Oil Work
It is very important to use the correct hydraulic oil for application when it comes to the operation of hydraulic circuits or equipment to achieve a longer service life.
Fluid that is based in mineral oil is one of the most commonly used fluids, but some systems require fire resistance due to its proximity to a heat source that could cause fire hazards.
Hydraulic oil’s main purpose to any equipment is to transmit energy. Different types of equipment have a pump that sends oil through the valve lines and the oil in those lines transmit the equipment’s energy to the actuator for it to perform work. The hydraulic oil must flow smoothly to make the equipment respond right away.
Your hydraulic oil must have good lubrication qualities as well. Pumps, cylinder, and motors need lubrication to make them efficient and to extend their life span. Some good hydraulic oils provide anti-wear additives that work well and are available from different suppliers.
Sealing is another thing to take note of when it comes to hydraulic oils to avoid leaks. Thin oils can flow through and could reduce efficiency of the equipment. Thicker fluids keep leakages from a minimum to none.
Here are some more properties that make hydraulic oil work.
1. Viscosity
This is the most important property when it comes to hydraulic oil since this is being applied to most pumps. Most producers consider specific viscosity limits for their pumps since it is best to stay within the limits of it. One reason on why specifying the viscosity is important is because if the pressure drops in the pump and the oil is too thick, it could damage the oil due to cavitation.
2. Viscosity Index
Also known as VI, it is the measurement of viscosity from one temperature to another. Using an oil with low Viscosity Index might begin well, but might also start some leakage and could cause damage at the start-up.
3. Pour Point
This is the lowest temperature at which an oil flows. It should be lower than the lowest temperature for the pump to have more lubrication.
4. Viscosity Modifiers
A property that enhances the oil to remain workable throughout a wide temperature range.
5. Wear Inhibitors
These are additives that bond with metal parts in a hydraulic system. Once the additives start working, this extends the equipment’s life by reducing wear.
Looking for the right hydraulic oil for your equipment could take a little amount of time to consider what is best to use. This is why you should at least know how to take care of your equipment by knowing what makes it durable.
