Embodiment Construction
[0016] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0017] combine Figure 1-5 , the present invention is a compressor lubricating oil chamber graphite seal, including axial pin 1, locking plate 2, spring plate 3, graphite body seat 4, radial pin 5, graphite ring 6, sealing body sleeve 7, spring 8. The sealing body sleeve 7 is the main load-bearing component of the graphite seal, and the installation groove of its outer circle fixes the graphite seal to the supporting stator assembly, and the installation groove of the inner hole restricts the graphite body seat 4 in the circumferential direction through the radial pin 5. To prevent the graphite ring 6 from rotating in the circumferential direction, the right end face of the graphite ring 6 interacts with its left end face to form a radial oil sealing effect. The elastic deformation of the spring 8 makes the graphite ring 6 tighten along the outer radial directio...

The invention aims at providing a graphite seal for a lubricating oil cavity of a compressor. The seal comprises a graphite ring, a sealing body sleeve, a graphite body base and a locking pressing plate, wherein both the graphite ring and the graphite body base are located in the sealing body sleeve, the graphite ring is located between the end face of the sealing body sleeve and the graphite bodybase, a mounting groove fixed to a supporting stator assembly is formed in the outer circle of the sealing body sleeve, a radial pin for circumferentially limiting the graphite body base is arrangedat the position of the mounting groove of an inner hole of the sealing body sleeve, a spring is arranged between the outer circle of the graphite ring and the sealing body sleeve, the locking pressingplate rotates in the circumferential direction to enable a protruding shoulder at the outer circle of the locking pressing plate to enter the mounting groove of an inner hole of the sealing body sleeve, and a spring plate piece is arranged between the locking pressing plate and the graphite body base. The graphite seal for the lubricating oil cavity can be applied to a gas compressor or a test gas compressor of a small gas turbine. A large amount of lubricating oil can be effectively sealed in the lubricating oil cavity by adopting a lubricating oil sealing device with the combined action ofthe graphite sealing assembly and the oil sealing ring.
Description
technical field [0001] The invention relates to a lubricating oil chamber seal, in particular to a lubricating oil chamber seal of a gas turbine. Background technique [0002] Test compressors, especially modular test compressors, usually have higher speed requirements. For safety reasons, compressors under high speed conditions need to adopt more effective lubrication and cooling for support bearings. The lubricating oil cavity seal of the compressor needs to effectively seal a large amount of lubricating oil to prevent it from entering the compressor flow channel and causing adverse effects on the performance and use of the compressor. Contents of the invention [0003] The object of the present invention is to provide a graphite seal for a lubricating oil chamber of a compressor that can effectively seal a large amount of lubricating oil in the lubricating oil chamber. [0004] The purpose of the present invention is achieved like this: [0005] The present invention ...
