Abstract

The invention discloses ship side thruster hydraulic oil which is formed through the following way: pentaerythritol ester and poly-alpha olefin are compounded, the mixture is used as base oil, and then the base oil is combined with multiple composite additives including an antiwear agent, an antioxygen, an anti-foaming agent, an anti-emulgator, an antirust agent, a metal deactivator, a friction improver and a corrosion inhibition assistant. The ship side thruster hydraulic oil can form a protective film on the surface of a hydraulic kinematic pair, resist pollution of seawater and has excellent anti-rust property, abrasion resistance, hydrolysis stability and emulsion resistance; in addition, the air release property and the anti-foaming property of the ship side thruster hydraulic oil are also excellent.

Description

technical field [0001] The invention relates to a ship and underwater engineering machinery, in particular to the field of hydraulic oil for ship side thrusters. Background technique [0002] Large-scale ships often encounter problems such as insufficient operating water area, high speed of hull movement, high inertia, and poor gyration in narrow waterways and ports. Maneuvering operations such as leaving the berth. In order to meet the safe operation requirements of the side thruster, it is equipped with a complete hydraulic system to ensure that the power can be accurately transmitted to the ship under the condition of considering the speed of the ship. Because the hydraulic equipment and hydraulic oil of ship thrusters are often affected by high temperature, high humidity, heavy load, impact, high salinity, sea tide and rain, the working environment is harsh. The hydraulic oil of the side thruster requires anti-rust, anti-emulsification, anti-seawater salt erosion, anti...
