Description
Technical field
The present invention relates to a kind of lubricating oil composition, specifically, relate to the low condensation point hydraulic fluid compositions of a kind of LV, be applicable to the various hydraulic machinery equipment of ice box and airport ground.
Background technology
At the hydraulicefficiency installation of China Han Qu work, can use L-HS hydraulicefficiency oil at present, but in some particular surroundings or under requiring; Like operation under China winter severe cold district, low temperature, the particularly hydraulicefficiency installation of operation in the open air, like the electric industry system; Be located at open-air high-tension switch gear; The hydraulicefficiency system of the fire-fighting crane of field work and at the hydraulicefficiency installation of severe cold district operation etc. requires hydraulicefficiency oil that enough little viscosity can be arranged in the time of-60 ℃, guarantees that hydro-pump starts smoothly; Simultaneously at high temperature can keep enough viscosity again, hydraulicefficiency installation is normally moved.
Existing L-HS 10 is the minimum hydraulicefficiency oil of present low temperature viscosity, and its-40 ℃ of kinematic viscosity are 1500mm
2/ s, minimum pour point is-45 ℃, be applicable to use temperature at-40 ℃ hydraulicefficiency installation, but under above-mentioned-60 ℃ environment, L-HS hydraulicefficiency oil just can not satisfy having required with oil of equipment hydraulicefficiency system.
In view of above reason, a kind of hydraulicefficiency oil that can under-60 ℃, use are badly in need of developing in China, and are lower than L-HS 10 use temperatures, the LV hydraulicefficiency oil that pour point is lower, thus ensure that hydraulicefficiency installation can normally move in the severe cold district.This oil product not only needs low-temperature performance superior, but also will have functions such as antioxygen is antirust.
Summary of the invention
The object of the present invention is to provide a kind of LV that is adapted at using on the various hydraulic machinery equipment of China's ice box and airport ground to hang down the condensation point hydraulic fluid compositions.
In order to realize the object of the invention, the present invention provides a kind of LV to hang down the condensation point hydraulic fluid compositions, and it is made up of following components in weight percentage content:
