MIL-SPEC HYDRAULIC FLUIDS
Hydraulic fluids are a large group of liquids
made of many kinds of chemicals.
Some of the most commonly
used fluids are synthetic lubricants, petroleum oils,
oil-water emulsions, and water-glycol mixtures. The main
characteristics of hydraulic fluid are proper viscosity, high
viscosity index, anti-wear protection, if applicable, proper
oxidation, proper pour point, rust inhibition, good
demulsibility, foaming resistance, and compatibility with seal
materials. Anti-wear oils are used in compact, high-pressure,
and capacity pumps that require extra lubrication protection.
They are used in auto transmissions, power steering and
brakes. They are used in forklift trucks, power steering and
brakes. They are used in Tractors, bulldozers, aircraft and
industrial machinery.
Some common types of hydraulic fluids
are mineral oil, organophosphate ester, polyalphaolefin,
castor oil, silicone, glycol esters and ethers.
Hydraulic fluids can contain a wide range of chemical
compounds; oils, butanol, esters (e.g. phthalates, like DEHP,
and adipates, like bis (2-ethylhexyl) adipate), polyalkylene
glycols (PAG), phosphate esters (e.g. tributylphosphate),
silicones, alkylated aromatic hydrocarbons, polyalphaolefins
(PAO) (e.g. polyisobutenes), corrosion inhibitors, etc.
Farm tractors and marine dredging may benefit from using
biodegradable hydraulic fluids based upon varieties of
vegetable oil since they are environmentally sensitive, and
when there is the risk of an oil spill from a ruptured line.
These oils are available in their designated military
specifications. Hydraulic systems will work efficiently if the
specific hydraulic fluid has low compressibility.
Brake
fluid is a type of hydraulic fluid with a high boiling point
and low freezing point.
Some hydraulic fluids have an oily
smell and others have no smell. Some are flammable and some
are not.
