The present application relates to the technical field of lubricating oil, and particularly relates to a special lubricating oil composition for gear box of port machinery equipment and a preparation method thereof.The preparation method of the present application comprises the following steps: preparing a graphene oxide lubricating additive by using graphene oxide and part of base oil; stirring uniformly extreme pressure anti-wear agent, rust inhibitor, antioxidant, demulsifier, pour point depressant, viscosity index modifier and the remaining part of base oil, then adding the graphene oxide lubricating additive and anti-foaming agent, continuing to stir and mixing uniformly to obtain the special lubricating oil composition for gear box of port machinery equipment.The lubricating oil composition prepared by the preparation method of the present application has excellent load-carrying and anti-wear performance, unique anti-micro-pitting performance, excellent oxidation resistance, low-temperature fluidity and water separation performance and the like, and is suitable for gear box lubrication working under harsh working conditions such as heavy load, impact load and low-temperature environment.

This utility model relates to the field of water separator technology, and more particularly to a water separator suitable for high-power systems. It includes a water separator housing, within which a horizontal partition at the bottom divides the space into an upper gas circulation chamber and a lower water storage chamber. The horizontal partition has several drainage holes. The gas circulation chamber is divided into an inlet chamber and an exhaust chamber by a vertical partition. A hydrogen return inlet is located on the upper part of one side of the inlet chamber. Several downwardly inclined inlet baffles are staggered on the side wall of the inlet chamber, and several upwardly inclined exhaust baffles are staggered on the side wall of the exhaust chamber. The top of each exhaust baffle has a downwardly curved barb. Stepped structures are also provided on the side walls of the inlet and exhaust chambers. Even with a large gas flow rate in a high-power fuel cell system, this design can improve water separation efficiency, effectively separating hydrogen from water, preventing large amounts of water from entering the hydrogen circulation pump and fuel cell stack, thus ensuring the stability of the hydrogen circulation pump and fuel cell system.
