How to choose hydraulic oil for hydraulic universal testing machine?
Many users do not pay attention to the choice of hydraulic oil when using the hydraulic universal testing machine, which will cause various problems and reduce the service life. So how do we choose hydraulic oil for the hydraulic universal testing machine?
The selection of hydraulic oil in the hydraulic universal testing machine should be considered from many aspects such as viscosity, abrasion resistance, oxidation resistance, shear safety, rust and corrosion resistance, foam resistance and air release. According to many pairs of comparative tests, the hydraulic oil on our hydraulic testing machine is generally a mixture of 46# or 68# anti-wear hydraulic oil. The hydraulic oil has the following characteristics and is very suitable for testing machines.
1. Viscosity temperature performance
Excellent viscosity-temperature performance, to ensure that hydraulic components get good lubrication, cooling and sealing under the conditions of changing working pressure and temperature
2. Wear resistance
Excellent extreme pressure and anti-wear performance, slow down the wear of equipment, and effectively extend the operating life of pumps and systems
3. Oxidation stability
Excellent oxidation stability, slow down the decay rate of oil products, and extend the oil drain period
4. Anti-foam and air release
Excellent anti-foaming and air release properties to ensure that the system can transmit static pressure energy sensitively, accurately and smoothly
5. Demulsibility and filterability
Excellent anti-emulsification and filterability, can quickly separate the water mixed in the oil, minimize filter clogging, and ensure the normal lubrication of the oil
High-quality medium-viscosity mineral oil should be used in hydraulic transmission, and the oil should not contain water, acid or other mixtures. The hydraulic oil should not decompose and become thick at ordinary temperature, and the oil must be filtered before it can be poured into the machine. The reference specification of hydraulic oil: specific gravity: 0.86—0.97; freezing point: -15℃ to -20℃; if you don’t understand the details during use, please call the sales technician to explain it to you in detail. The recommended hydraulic oil is used. Hope it can help everyone!
