Specifically, in the hydraulic cylinder transmission operation, the hydraulic oil is not only the medium of the hydraulic cylinder transmission power, but also the lubricant, and it plays a sealing role in the components of the hydraulic cylinder. Therefore, in order to ensure the reliability, effectiveness and economy of the hydraulic cylinder system, the hydraulic oil B selected by the user for the hydraulic cylinder must ensure the following performance requirements:

What are the performance requirements of hydraulic oil for hydraulic cylinders?

One: appropriate viscosity

Users should consider the viscosity of hydraulic oil when selecting hydraulic oil for hydraulic oil cylinders with guaranteed quality, and the viscosity will affect the size of the intermolecular friction resistance when the hydraulic oil system flows. When the hydraulic oil viscosity is too large, the oil flow resistance and energy The loss increases to cause the efficiency of the system to drop sharply. It is worth noting that when the viscosity of the hydraulic oil is too small, the degree of lubrication of the hydraulic cylinder components cannot be determined, which aggravates the wear of the components and the low efficiency of the hydraulic cylinder system.

Two: good viscosity temperature characteristics

Specifically, users should consider the viscosity-temperature characteristics of hydraulic oil in the process of selecting hydraulic oil for durable hydraulic oil cylinders. The viscosity of hydraulic oil will change with the rise and fall of temperature. For example, the viscosity of hydraulic oil cylinder system in operation will decrease with the increase of temperature, so that the internal leakage of hydraulic system will not be too large. Therefore, the viscosity-temperature characteristics of hydraulic oil are extremely critical in the operation of hydraulic cylinders.

Three: good wear resistance and lubricity

Users for the hydraulic cylinder to select the hydraulic oil process also need to consider the anti-wear and lubricity of the oil, the lubricity of the hydraulic oil can reduce mechanical friction, and the equipment system can ensure that under different pressure and speed and other conditions have enough oil film strength. In addition, the user should also take into account the quality of the hydraulic oil purity to minimize the content of mechanical impurities and dust, so as to avoid affecting the performance of the hydraulic cylinder.

Not only that, users need to take into account the anti-rust performance of the medium in the process of selecting oil for the hydraulic cylinder. The hydraulic oil mainly covers the surface of the parts of the hydraulic cylinder to avoid oxidation and corrosion. Therefore, the anti-rust performance of the hydraulic oil is extremely important. All in all, users need to carefully consider the above issues in the process of selecting hydraulic media.
