Knowledge expansion: how to choose the right hydraulic oil

Hydraulic oil plays a role of transmitting pressure, lubrication, cooling and sealing in hydraulic system. Improper selection of hydraulic oil is the main reason for early failure and durability decline of hydraulic system. The hydraulic oil should be selected according to the brand specified in the manual. When special circumstances need to be used, the performance should be the same as that of the original brand. Different grades of hydraulic oil can not be mixed, in order to prevent the chemical reaction of hydraulic oil, performance changes. Dark brown, milky white, smell of the hydraulic oil is metamorphic oil, can not be used.
