Technical Field

The invention relates to a lubricating oil filter, in particular to a lubricating oil filter of a gas turbine, and belongs to the field of gas turbines.

Background

The gas turbine lubrication system ensures that the bearing parts and the gear meshing parts of the gas turbine are lubricated and cooled under all working conditions of the gas turbine. The oil contamination in the lubrication system comprises friction wear and corrosion of friction mating parts, oil coking or oil sludge, sundries entering through a sealing device, cutting scraps remained in a bearing cavity of a gas turbine, and dirt mixed in when the oil is filled, and the oil contamination can block an oil nozzle, so that a bearing is burnt due to no oil lubrication and cooling, or enters the working surface of a gear and the bearing, the friction wear is aggravated, the early failure is caused, and the service life of the bearing is shortened. Keeping the lubricant clean is a very important measure to improve the reliability and life of the gas turbine. The gas turbine oil filter is arranged in front of the oil nozzle, behind the fine oil filter, for protecting the gas turbine from accidental contamination that may occur after the fine oil filter, which allows for short time testing of the gas turbine without the fine oil filter.

Disclosure of Invention

The invention aims to solve the problems that the existing lubricating oil filter is not compact in structure, is not resistant to impact vibration and is low in reliability, and further provides a lubricating oil filter of a gas turbine.

The technical scheme adopted by the invention for solving the problems is as follows: the invention comprises a filter shell and a filtering mechanism, wherein a first cavity is arranged in the shell, the filtering mechanism is arranged in the first cavity, the lower part of the filter shell is provided with an inlet, and the upper part of the filter shell is provided with an outlet.

Furthermore, the filtering mechanism comprises a framework and a filter screen assembly, the framework is inserted into the first cavity, the framework is internally provided with a second cavity, the upper part of the framework is provided with a plurality of holes, an oil outlet at the upper end of the framework is communicated with an outlet, and the filter screen assembly is sleeved on the framework.

Further, the filter screen subassembly includes first filter screen and second filter screen, and first filter screen, second filter screen suit in proper order are on the skeleton from outer to inner, and the upper end edge of first filter screen and second filter screen is located between hole and the oil-out of skeleton upper end.

Furthermore, a plurality of holes are uniformly distributed on the outer wall of the upper part of the framework along the circumferential direction.

Furthermore, the invention also comprises a sealing cover which is fixedly arranged at the opening at the upper end of the shell.

Further, the edge of the sealing cover is connected with the outer edge of the opening of the shell through a plurality of bolts.

Furthermore, the invention also comprises a sealing ring which is arranged between the lower surface of the sealing cover and the upper surface of the outer edge of the opening of the shell.

The invention has the beneficial effects that: the invention can roughly purify the lubricating oil, effectively intercept larger impurities formed by damage of the fine filter element, can perform short-time test on the gas turbine without a fine lubricating oil filter, and has compact structure, impact vibration resistance and high reliability; the invention has compact structure, shock vibration resistance and high reliability; the invention has simple structure, convenient and fast installation and low manufacturing cost.
