Negative consequences of high oil temperature in hydraulic system

Hydraulic system in the oil temperature increased caused of bad consequences: (1) makes oil liquid stick degrees declined, leak increased, reduced has volume efficiency, even effects work institutions of normal movement; (2) makes oil liquid metamorphic, produced oxides impurities, jam hydraulic components in the of small hole or gap, makes of cannot normal work; (3) caused hot expansion coefficient different of relative movement parts Zhijian of clearance variable small, even card died, cannot movement; (4) caused machine or mechanical of hot deformation, damage original of precision.
