specific Embodiment approach 1

[0013] Specific implementation mode one: combine figure 1 This embodiment is described. The gas turbine lubricating oil filter in this embodiment includes a filter housing 1 and a filter mechanism. The housing 1 is provided with a first chamber a, and the filter mechanism is arranged in the first chamber a. The filter housing The lower part of the body 1 is provided with an inlet 6, and the upper part of the filter housing 1 is provided with an outlet 7.

[0014] This embodiment can roughly purify the lubricating oil, effectively intercept larger impurities formed due to the damage of the fine filter element, and can conduct a short-term test on the gas turbine without a fine lubricating oil filter.

specific Embodiment approach 2

[0015] Specific implementation mode two: combination figure 1 This embodiment is described. The filter mechanism of the gas turbine lubricating oil filter in this embodiment includes a skeleton 8 and a filter screen assembly. The skeleton 8 is inserted in the first chamber a, and the second chamber b is arranged in the skeleton 8. The skeleton 8 A plurality of holes 5 are arranged on the upper part of the frame 8, and the oil outlet at the upper end of the frame 8 communicates with the outlet 7, and the filter screen assembly is sleeved on the frame 8. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0016] Specific implementation mode three: combination figure 1 Describe this embodiment, the filter screen assembly of the gas turbine lubricating oil filter in this embodiment includes a first filter screen 3 and a second filter screen 4, and the first filter screen 3 and the second filter screen 4 are sequentially set on the skeleton from outside to inside 8, and the upper edges of the first filter screen 3 and the second filter screen 4 are located between the hole 5 and the oil outlet at the upper end of the frame 8. Other components and connections are the same as those in the second embodiment.

Abstract

The invention relates to a lubricating oil filter, particularly relates to a gas turbine lubricating oil filter, and aims to solve the problems that an existing lubricating oil filter is not compact in structure, not resistant to impact and vibration and low in reliability. The filter comprises a filter shell and a filtering mechanism, wherein a first cavity is formed in the shell, the filtering mechanism is arranged in the first cavity, an inlet is formed in the lower portion of the filter shell, and an outlet is formed in the upper portion of the filter shell. The invention belongs to the field of gas turbines.

Description

technical field [0001] The invention relates to a lubricating oil filter, in particular to a gas turbine lubricating oil filter, and belongs to the field of gas turbines. Background technique [0002] The gas turbine lubrication system ensures lubrication and cooling of the bearing components and gear meshing parts of the gas turbine under all working conditions of the gas turbine. Lubricating oil pollution in the lubrication system includes friction, wear and corrosion of frictional counterparts, coking or sludge of lubricating oil, debris coming in through the sealing device, chips remaining in the bearing cavity of the gas turbine, dirt mixed in when filling the lubricating oil, lubricating oil Contamination will block the lubricating oil nozzle, cause the bearing to burn due to lack of lubricating oil lubrication and cooling, or enter the working surface of the gear and bearing, aggravate friction and wear, cause early failure, and reduce its service life. Keeping lubri...
