Problems solved by technology

[0004] In the existing diffuser manufacturing method, there are many defects, which are as follows: 1. Due to the control of the throat area of ​​the diffuser, the requirements for the profile of the diffuser blade are high, but the actual processing is completed. The profile of the blade line is poor, which cannot meet the production requirements; 2. In order to better install the diffuser into the steam compressor and better realize the function of the diffuser, it is necessary to strictly control the assembly clearance, b

Abstract

The invention discloses a manufacturing method of a vapor compressor diffuser, which comprises the following steps: a. rough heat treatment; b. rough turning of the diffuser big end, outer circle, inner hole and first stepped surface; c. rough turning The small end, outer circle, inner hole and the second step surface of the diffuser; d, the large end, outer circle, inner hole and the first step surface of the semi-finishing diffuser; Milling blades, after finishing milling, send three-coordinate inspection; f, after passing the inspection, finish turning the end surface and inner hole of the small end of the diffuser; g, finishing turning the end surface and inner hole of the large end of the diffuser; h, marking and drilling Use the center line for alignment, drill and tap; i, file and repair the bottom of the blade flow path; j, conduct a penetration test on the blade. The invention has the advantages of high profile of blade profile, high requirements on flatness and verticality of end faces, and good process performance.

Description

technical field [0001] The invention relates to the technical field of steam compressors; in particular, it relates to a method for manufacturing a diffuser of a steam compressor. Background technique [0002] The steam compressor is the key equipment for the heat recovery system to increase the steam temperature and pressure by compressing the steam generated. Its function is to pressurize and heat up low-pressure or low-temperature steam to meet the temperature and pressure requirements required by the process or project. Its working principle is that the compressor impeller rotates on the shaft of the compressor, the gas entering the compressor impeller is rotated, and then enters the diffuser, where the kinetic energy of the gas is converted into the required pressure energy. [0003] A vapor compressor consists of two aspects, a rotor and a stator. The rotor is composed of impeller, main shaft, balance disk, thrust disk and other components, and the stator is composed...
