Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] Taking the processing of the developed large three-row two-stage compression labyrinth compressor cylinder as an example, the preparation method of the labyrinth compressor cylinder is explained as follows:

[0014] 1) After drawing the processing line on each plane of the cylinder casting, the gantry planer is used for rough planing, horizontal boring and rough boring for each surface, after heat treatment to relieve stress, the upper and lower sides of the gantry planer are semi-finish planed, the valve hole is roughly and finely planed, and the valve hole is horizontally rough and finely boring. The size of each step in the hole and the taper surface, rough boring each cylinder diameter, use a contour pad, press the top surface on the HF-4M pentahedron machining center worktable and align it, rough and fine milling the two sides, and drill the center...

Abstract

The invention encloses the following step of: rough machining of the labyrinth compressor cylinder on common machine tools and fine machining of the valve opening; setting separately the screw-pitch of the labyrinth groove and the depth of the helical groove on the wall of the cylinder to be the feeds per revolution and the cutting depth and then working on the labyrinth groove using a pentahedron working centre; fine boring of a same-line cylinder diameter and a filling hole in the pentahedron centre and milling a plurality of arc air vents on the pentahedron working centre.

Description

A technical field [0001] The invention relates to a preparation method of industrial mechanical equipment, in particular to a preparation method of a labyrinth compressor cylinder. Two background technology [0002] Compared with the traditional reciprocating piston compressor, the labyrinth compressor has obvious advantages. It is a non-contact seal, which can realize the compression with particles, and has lower requirements for the pre-treatment of the compressor. The compressed medium can be oil-free and wear-free. , without any pollution to the compressed medium, the labyrinth compressor is stable and reliable in operation, strong in adaptability, and low in maintenance and operation costs. Because the structure of the labyrinth compressor is different from that of the traditional reciprocating piston compressor, the structure of its cylinder is also very different. The shape of the reciprocating piston compressor cylinder is round. One cylinder has only one cylinder a...
