Degassing pans for gas turbine lube oil tanks

Abstract

The invention provides a degassing pan for a lubricating oil tank of a gas turbine, which belongs to the field of oil supply for a power unit, and in particular relates to a degassing pan for a lubricating oil tank of a gas turbine. The degassing tray includes a degassing tray body, which is horizontally arranged on the inner wall of the fuel tank lower than the oil return port of the system, and is used to receive the oil return of the system; a step is vertically arranged on the side of the degassing tray body away from the oil return port, The bottom of the step is connected to the main body of the degassing plate; the top of the slope is connected to the top of the step, and the end of the slope goes deep into the interior of the fuel tank; the oil discharge hole is opened on the main body of the degassing plate, which can significantly reduce the risk of return oil falling into the fuel tank. Shock potential energy, reducing the air mixed in the lubricating oil. In addition, there are steps designed on the degassing plate, which has a certain amount of oil storage space, which can ensure that the lubricating oil is fully exhausted before recirculation, effectively reducing the area occupied by the oil tank and the manufacturing cost.

Description

technical field [0001] The invention relates to the field of power plant oil supply, in particular to a degassing pan used for a lubricating oil tank of a gas turbine. Background technique [0002] The lubricating oil system is one of the important auxiliary systems in the gas turbine system, which provides clean and clean lubricating and cooling oil for the bearings of gas turbines, gearboxes, generators and other equipment to ensure the normal start-stop and safe operation of the gas turbine system . Lubricating oil will be mixed with a large number of air bubbles during operation, which will significantly increase the resistance of the oil pipeline, reduce the specific heat and heat transfer coefficient of the lubricating oil, not only reduce the heat transfer performance of the lubricating oil cooler, but also deteriorate the friction of the mating surface cooling and lubrication conditions. Therefore, in order to ensure that the lubricating oil has enough time to sepa...

Problems solved by technology

Although this technology can reduce the gas content in lubricating oil to a certain extent, it is not suitable for large-scale production due to its complex structure and high manufacturing cost.

[0004] Other oil return devices used in the prior art usually directly discharge into the oil tank through the oil return pipe, or the oil return pipe is set to have a certain slope for buffering, but this method can only reduce the oil return discharge to a certain extent. When entering the oil tank, it impacts the air mixed in, but it cannot remove the gas that has been entrained in the returned oil.
