Processing method of centrifugal compressor clapboard

Abstract

The invention discloses a processing method of a centrifugal compressor clapboard. The processing method of the centrifugal compressor clapboard comprises the steps of fixedly combining an upper sideplate and an upper blade disk, fixedly combining a lower side plate and a lower blade disk, and accomplishing the assembling of an upper clapboard and a lower clapboard; finish-machining center parting surfaces, excircles and end surfaces of the upper clapboard and the lower clapboard; aligning the excircles and planes of the end surfaces of the upper clapboard and the lower clapboard; fixedly connecting the upper clapboard and the lower clapboard on the center parting surfaces, and accomplishing the assembling of the whole clapboard; finish-machining the whole clapboard, and enabling an innercircle, an excircle and the end surface of the whole clapboard to meet the dimensional requirement of a drawing; disassembling the upper clapboard and the lower clapboard, trimming flashing and burrsof the upper clapboard and the lower clapboard; and derusting the upper clapboard and the lower clapboard, so that the processing of the centrifugal compressor clapboard is accomplished. The invention realizes the practical and high-efficiency processing method of the centrifugal compressor clapboard, and fills the technical blank of a current centrifugal compressor clapboard.

Description

technical field [0001] The invention belongs to the technical field of manufacturing centrifugal compressors, and in particular relates to a processing method for a partition plate of a centrifugal compressor. Background technique [0002] Baffles are gas passages that form stationary elements in centrifugal compressors. The role of the intake baffle is to form an intake chamber together with the cylinder to guide the gas to the inlet of the first stage impeller; the exhaust baffle acts as the final diffuser and the exhaust chamber; the section baffle is to separate Two-stage exhaust port or air inlet; the function of the middle partition is to form a diffuser to convert the kinetic energy of the gas coming out of the impeller into pressure energy, and the second is to form a bend and a reflux device to make it come out of the diffuser. The gas turns and enters the next stage impeller in a certain direction for compression. [0003] Existing compressor diaphragms mainly co...

AI Technical Summary

Problems solved by technology

[0003] Existing compressor diaphragms mainly consist of side plates and blisks, and since the side plates and blisks have a large volume and weight, assembling side plates and blisks into a diaphragm requires a lot of labor costs, so , a processing method for the centrifugal compressor diaphragm with low processing cost and short processing time needs to be solved urgently
