Problems solved by technology
The existing problem is: since all the connecting holes and positioning holes have been processed before finishing the large end and small end, but in process 7, the large end is cut intermittently and has a large margin, and each feed The amount and cutting amount are small, the processing efficiency is low, and the tool wear and the vibration of the machine tool are relatively large, which affects the accuracy of the machine tool

The invention discloses a machining method of a diffuser for a vapor compressor and belongs to the technical field of vapor compressors. The machining method primarily comprises the following steps: carrying out thermal treatment; roughly turning the big end of a workpiece; roughly turning the small end of the workpiece and reserving finish turning allowance on the end surface of a blade; carryingout semi-extractive turning of the big end of the workpiece; drawing a central line for alignment at the big end and the small end of the workpiece; carrying out finish-milling of a blade runner; carrying out finish turning of the small end of the workpiece; carrying out finish turning of the big end of the workpiece; drawing a central line for drilling at the big end of the workpiece; drilling aconnecting hole and a positioning hole in the big end of the workpiece; milling and repairing the bottom of the runner; and carrying out penetrant inspection on the blade. The machining method disclosed by the invention integrates original rough milling and finish milling of the blade into a finish milling step, and a contour block is used to pad and a pressing plate is built to mill, so that themilling tool is saved and the machining cost is lowered.
Description
technical field [0001] The invention belongs to the technical field of steam compressors, and relates to a method for processing a diffuser for a steam compressor. Background technique [0002] In recent years, with the general trend of national energy conservation and emission reduction, steam compressors have been widely used. The steam compressor is the key equipment for the heat recovery system to increase the steam pressure by compressing the fresh steam generated. The diffuser is an energy-saving technology that reuses the energy of the secondary steam generated by itself to reduce the demand for external energy. The working principle of the steam compressor is: the compressor impeller rotates on the shaft of the compressor, the gas enters the compressor impeller and is rotated, and then the gas enters the diffuser, and the diffuser converts the kinetic energy of the gas into the required pressure energy . [0003] The steam compressor is composed of rotor and stator...
