What kind of hydraulic oil is the general lift of a car lift? How much is the viscosity?
Now the viscosity of the oil is not like the previous 46 # can be used in winter and summer, recommended grade HM46 anti-wear hydraulic oil, better than the HL hydraulic oil viscosity in the case of high pressure oil film protection, if it is their own Car recommended the use of Mobil, Sun, Shell, BP, long life anti-wear hydraulic oil, with two or three years after you know the difference, and correct it, the viscosity of industrial lubricants grade 35 no hydraulic oil, respectively For the 7/10/15/22/32/46/68/100/150/220/320/460/680 / etc Great Wall OKorder Gaoqiao Petrochemical has a 40 # thickening hydraulic oil. Low temperature -35 degrees above the case can use HV low-temperature anti-wear hydraulic oil, if the lower can use aviation hydraulic oil, or synthetic hydraulic oil, but the price is much more expensive, there are problems,
Recommended hydraulic oil No. 46. Winter with 46, then the lift will slow down, if the winter in the indoor operation, the temperature above 4 degrees Celsius, throw can use 46 hydraulic oil. Otherwise you can use 35 hydraulic oil.
Generally with 46 good, viscosity 35.
Hydraulic oil is the use of hydraulic pressure hydraulic system used in the hydraulic medium, in the hydraulic system plays an energy transfer, anti-wear, system lubrication, corrosion, rust, cooling and so on. For hydraulic oil, the hydraulic device should first meet the requirements of the viscosity of the hydraulic device at the operating temperature and the starting temperature. The viscosity of the lubricating oil is directly related to the hydraulic action, the transfer efficiency and the transfer accuracy, and also requires the viscosity- And shear stability should meet the various needs of different applications. There are a wide variety of hydraulic oils, different classification methods, for a long time, used to use the classification, but also according to the type of oil, chemical composition or flammability classification. These classification methods only reflect the oil production, but the lack of systematic, it is difficult to understand the relationship between oil and development.
