Basically any liquid can be used as a medium for power transfer.<\/span> But in the hydraulic system requires specific requirements as discussed previously in connection with the construction and operation of the system.<\/span> Broadly speaking hydraulic fluids are grouped into two general categories:<\/span>
\n a.<\/strong><\/span> Hydraulic oil (hydraulic oils)<\/strong><\/span>
\n Hydraulic oil based on mineral oil is usually used extensively in tooling machines or also industrial machines.<\/span><\/p>\n

According to the standard DIN 51 524 and 512 525 and in accordance with the characteristics and composition of hydraulic oil divided into three (3) classes: \uf0b7<\/span>
\n – Hydraulic oil HL \uf0b7<\/span>
\n – Hydraulic oil HLP \uf0b7<\/span>
\n – Hydraulic oil HV<\/span><\/p>\n

The coding with letters such as the above meaning is as follows: For example, the hydraulic oil with the code: HLP 68 means:<\/span>
\n H = Hydraulic oil<\/span>
\n L = code for oil additives (additive) to improve corrosion prevention and \/ or an increase in the age of oil<\/span>
\n P = code for additive which improves the ability to receive the load.<\/span>
\n 68 = oil viscosity level (see table at HO 4)<\/span><\/p>\n

b.<\/strong><\/span> Fire-resistant hydraulic fluids (Low flammabilty)<\/strong><\/span>
\n<\/strong> What is meant by a hydraulic fluid fire resistant hydraulic fluids that are not easily or can not burn.<\/span> This kind of hydraulic fluid used in the hydraulic system places or machines that the fire risk is high enough, such as:<\/span>
\n \uf0b7 – Die casting machines<\/span>
\n \uf0b7 – Forging presses<\/span>
\n \uf0b7 – Hard coal mining<\/span>
\n \uf0b7 – Control units for power station turbines<\/span>
\n \uf0b7 – Steel works and rolling mills.<\/span><\/p>\n

Basically, fire resistant hydraulic fluid is made from a mixture of oil with water or synthetic oil.<\/span><\/p>\n

Hydraulic fluids including expensive items.<\/span> Treatment less or even no good against hydraulic fluid will further add to the high price of hydraulic systems.<\/span> Whereas if we obey the rules on the treatment \/ maintenance of hydraulic fluid, the liquid damage or damage to system components will be avoided and hydraulic fluid and the system will be more durable.<\/span><\/p>\n
