Fluid power actuators, lubricants, and fluids are all vital to the proper function of complex machinery or equipment. This material describes what hydraulic oil is and its purpose types, and best practices in using it.
What is Hydraulic Oil?
Hydraulic oils are fluids that are precisely designed for the hydraulic systems and are used for the purpose of transmitting power. It is important in the lubrication of moving parts, prevention of rust and also for heat removal.
The Key Functions of the Hydraulic Oil
. Power Transmission: hydraulic oil encased in the system acts as energy transmitter between the dynamic system of the hydraulic system components to provide for continuity of the operations.
. Lubrication: Affects the wear and tear of moving surfaces by interposing a film of oil between them.
. Heat Transfer: Assists in heat exchange; this helps to support the desired heat value in the system.
. Contaminant Removal: Helps to keep other parts of the system free from clogged dirt by collecting and holding foreign substances.
Types of Hydraulic Oils
Hydraulic oils are available in different formulations such as:
1.Mineral Oil Based – Most commonly used and is produced from the process of refining crude oil.
2.Biodegradable Oil – Used in Bio and Eco Applications made from advanced synthetic and natural esters.
3.Water-Based Fluids – For certain Applications and Available with Low Flash Point.
Selecting the Appropriate Hydraulic Oil
The selection of the hydraulic oil is influenced by:
Viscosity: very crucial for operational efficiency when temperatures go high and low depending on the weather
Additives: Certain additives contain the possibility of failure of the machine when used under certain conditions.
Conditions of Use: Factors such as temperature, pressure and type of contaminants if any should be considered.
Maintenance Tips
Routine Inspection: Besides the filling, the condition of oil should be checked too as much as possible to avoid breakdown.
Contamination Control: Use filtration systems to avoid dirty oil.
Timely Changes: Avoidischeating the oil change schedules provided by the manufacturer of the hydraulic oil system.
