A centrifugal compressor thrust bearing

Abstract

The invention relates to the technical field of bearings, and provides a thrust bearing of a centrifugal compressor. The bearing comprises a thrust block, a clamping hoop, an elastic pad, an adjustment pad, a bearing shell and a positioning pin, wherein the adjustment pad is connected with the bearing shell; the elastic pad is connected with the adjustment pad and the thrust block respectively; the positioning pin is connected between the adjustment pad and the bearing shell; the clamping hoop is connected with the bearing shell and the thrust block respectively. By design of a convex strip on the thrust block, pouring of a babbitt metal layer on the thrust block and design of concave and convex alternated bosses on the adjustment pad, the adaptive adjustment capacity of the thrust bearing is obviously improved, and the operation is more stable and reliable; the thrust bearing of the centrifugal compressor is simple and compact in structure; the precision between bearings is easy to guarantee, and the bearing is more convenient to mount and detach; production manufacturing and maintenance are facilitated; the stability and the reliability of operation of the centrifugal compressor unit are effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a centrifugal compressor thrust bearing. Background technique [0002] At present, domestic and foreign petrochemical, refrigeration and other industries generally use centrifugal compressors to transport and compress various gases, and the bearing system is an essential and important part of centrifugal compressors, which directly determines the operation and stability of centrifugal compressors. The main guarantee of normal operation and service life. At present, the thrust bearings of this type of equipment are generally implemented in the form of fixed thrust surfaces or tilting pad bearings with a relatively complex structure. The bearing load of the fixed thrust surface has certain limitations, and there is no self-adaptive ability, and the operation is stable. However, the above-mentioned tilting pad bearing has a relatively complicated system, complicated structural des...

Problems solved by technology

At present, the thrust bearings of this type of equipment are generally implemented in the form of fixed thrust surfaces or tilting pad bearings with a relatively complex structure. The bearing load of the fixed thrust surface has certain limitations, and there is no self-adaptive ability, and the operation is stable. Poor, but the above-mentioned tilting pad bearing has a more complex system, complicated structural design and lubricating oil system, relatively large dimensions, inconvenient installation and disassembly, and high manufacturing cost
