This invention relates to the field of aero-engine bearing testing technology, and discloses a bearing testing device, including a main shaft, a test bearing assembly, a sealing structure, and a maintenance assembly. The test bearing assembly includes a first bearing housing and a test bearing. The first bearing housing has a first air inlet. The adjusting ring of the maintenance assembly has a first end and a second end. An oil injection ring is spaced apart from the second end to form a sealing channel. A stationary ring is connected to the oil injection ring and positioned close to the second end. The first air bleed channel of the oil injection ring communicates with the second air bleed channel, and the first air bleed channel communicates with the first air inlet. The other end of the second air bleed channel communicates with the sealing channel. This invention, through the spaced arrangement of the rotating and stationary rings and the airflow guidance of the sealing channel, introduces high-temperature gas through the first air inlet of the first bearing housing and guides it into the sealing channel, recreating a real sealing scenario. This makes the bearing test verification more comprehensive and closely resembles the actual working condition, significantly improving the reference value of the test data.

The application discloses a compression assembly and a static scroll and a scroll compressor. The compression assembly comprises a static scroll, a base body and a static disc profile, the base body is provided with a mounting groove, and the static disc profile is located in the mounting groove; the end face of the base body around the opening of the mounting groove is a thrust face, the thrust face comprises a first friction area and a second friction area, the second friction area is located on the radial outer side of the first friction area, the first friction area is provided with an annular first oil groove, and the second friction area is provided with an oil groove network, the oil groove network comprises an annular second oil groove and a third oil groove communicated with the second oil groove; and a dynamic scroll is arranged on one side of the static scroll and in contact with the thrust face, the dynamic scroll is provided with an oil feeding hole opening towards the thrust face, and the oil feeding hole is intermittently communicated with the first oil groove. The compression assembly has the advantages of lubricating the thrust face on the static scroll from different positions, improving the lubricating efficiency of the thrust face, meeting the lubricating requirements of high-speed compressors and the like.
