Abstract

The invention discloses a processing method for a diaphragm of a centrifugal compressor, which includes: fixing the upper side plate and the upper blisk together, fixing the lower side plate and the lower blisk together, and completing the assembly of the upper and lower partitions; Finish the mid-section, outer circle and end surface of the upper and lower partitions respectively, and align the outer circle and end plane of the upper and lower partitions; fix the upper and lower partitions at the mid-section , complete the assembly of the whole partition; finish the whole partition, so that the inner and outer circles and end faces of the whole partition meet the size requirements of the drawing; disassemble the upper and lower partitions, and trim the upper and lower partitions Flash, burrs, and anti-rust treatment on the upper and lower partitions, complete the processing of centrifugal compressor partitions. The invention realizes a practical and high-efficiency preparation method for processing the diaphragm of the centrifugal compressor, and solves the technical blank of the diaphragm of the centrifugal compressor at present.

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...
