What is the essential difference between hydraulic oil and lubricating oil?

Answer:

Hydraulic oil is used for cylinder work! Lubricating oil is used for bearings! The place is different!
Hydraulic oil, as its name suggests, is used in the hydraulic system of oil, the function is not compressed, can effectively transfer the energy of the oil, requiring hydraulic oil compressibility as small as possible. Viscosity temperature better, there is a certain degree of lubrication; general hydraulic oil viscosity is low. Lubricating oil generally refers to the use of moving parts, to the moving parts lubrication, to prevent moving parts wear oil, a wide range of species, different applications, lubrication requirements are also different. Suggest professional books.
The lubricating oil includes hydraulic oil is a kind of lubricating oil is a general hydraulic oil lubricating oil for a strong oil
Definition of hydraulic oil,Hydraulic oil pressure is the hydraulic medium used in hydraulic system with liquid pressure energy. It plays the role of energy transmission, system lubrication, corrosion prevention, rust prevention and cooling in the hydraulic system. For the hydraulic oil, should first meet the requirements of the hydraulic device in the operating temperature and the starting temperature of the liquid viscosity, the viscosity change of oil is directly related to hydraulic operation, transmission efficiency and transmission precision, but also oil viscosity temperature properties and shear stability should meet the needs of different uses of the proposed.Definition of lubricating oilLubricating oil is used in various types of machinery to reduce friction, protection of machinery and processing parts of liquid lubricants, mainly from lubrication, cooling, rust, cleaning, sealing and buffering.By contrast, some of the effects of hydraulic oils and lubricants are the same... But they differ in their environmental conditions and are higher than those for hydraulic fluids...
