Modified thrust bearing for high-pressure cylinder of carbon dioxide compressor

Abstract

The invention provides a modified thrust bearing for a high-pressure cylinder of a carbon dioxide compressor. The modified thrust bearing comprises a bearing base ring, a guide pipe and a tile block;and one end of the guide pipe is connected with an oil groove of the bearing base ring, and the other end of the guide pipe is connected with an oil guide groove of the tile block, so that the oil groove of the bearing base ring communicates with the oil guide groove of the tile block. Lubricating oil is forcibly sent to the tile surface through oil pressure via the guide pipe to forcibly lubricate the tile surface to form a more stable oil film, the lubricating oil enters the tile surface more effectively, and meanwhile, the fluidity of return of the lubricating oil is enhanced; original lubricating environment is changed, so that tile block temperature is greatly reduced, consequently, long-period stable operation and safe production of a unit are guaranteed, maintenance frequency is reduced while operation hidden danger is eliminated, maintenance cost is reduced, labor intensity of maintenance personnel is reduced, and remarkable economic benefits are brought; and when a compressoris started and stopped multiple times, the operation of the compressor is stable, the temperature of the thrust bearing is normal, and the running temperature change of the thrust bearing is not influenced due to the stop and start frequency.

Description

technical field [0001] The invention belongs to the technical field of bearings, in particular to a modified thrust bearing of a high-pressure cylinder of a carbon dioxide compressor. Background technique [0002] CO in recent years 2 During the start-up and operation of the centrifugal compressor unit, the temperature of the thrust bearing bush is often high, which is close to or even exceeds the chain alarm value of the unit detection system, which brings many hidden dangers to the long-term operation of the unit and safe production. The temperature of the thrust bearing changes with the load. and running time continued to rise, causing the unit to be shut down for maintenance. These problems not only affect the safe operation of the device, but also increase the maintenance cost, which is not conducive to the economic benefit of the enterprise. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a...

Problems solved by technology

[0002] CO in recent years 2 During the start-up and operation of the centrifugal compressor unit, the temperature of the thrust bearing bush is often high, which is close to or even exceeds the chain alarm value of the unit detection system, which brings many hidden dangers to the long-term operation of the unit and safe production. The temperature of the thrust bearing changes with the load. and running time continue to increase, causing the unit to be shut down for maintenance

These problems not only affect the safe operation of the device, but also increase the maintenance cost, which is not conducive to the economic benefits of the enterprise.
