Embodiment Construction

[0038] The specific implementation of the wind tunnel compressor rotor assembly method of the present invention will be described below in conjunction with the accompanying drawings.

[0039] Such as figure 1 As shown, the schematic diagram of the rotor mechanism of the large compressor described in the present invention, the first-stage hub 102 is formed after the first-stage hub and the second-stage hub are welded, the second-stage hub 103 is formed after the third-stage hub and the fourth-stage hub are welded, and the first section After the hub 102 and the second segment hub 103 are fastened and fixed by bolts at the seam position, they constitute the overall hub of the compressor rotor. The two ends of the hub are respectively installed with the outlet side shaft 100 and the inlet side shaft 101, and the outlet side shaft 100 is connected with the hydraulic pressure. After the cylinder 104 is fitted and installed, the hydraulic cylinder 104 is connected to the intake side...

Abstract

A wind tunnel compressor rotor assembly method according to the present invention includes: horizontally fixing the air outlet side shaft on the operating platform; assembling the hydraulic cylinder with the air outlet side shaft; assembling the hub assembly with the air intake side shaft; Each level of adjustment cylinders is installed in the hub assembly; the hub assembly is assembled with the intake side shaft; the wind tunnel compressor rotor assembly method adopts a vertical assembly scheme, which eliminates the seams of large-sized parts The high-precision positioning problem greatly reduces the difficulty of assembly and simplifies the assembly steps, which can ensure that after the wind tunnel compressor rotor is assembled, all indicators meet the design requirements.

Description

technical field [0001] The invention relates to an assembly method of a compressor, in particular to an assembly method of a wind tunnel compressor rotor. Background technique [0002] Wind tunnel compressors are large-scale compressor equipment. Their rotors have complex structures, many parts, large dimensions, and a weight of 50-80 tons. At present, there are no relevant standards for the design, manufacture and inspection of wind tunnel compressor rotors. The rotor is multi-component spigot positioning, and the size and weight of each single piece are super-large components in related fields, and the design requires high positioning accuracy. [0003] Due to its large positioning spigot size (φ1500-2500mm) and high positioning accuracy (positioning gap 0.10-0.20mm), there is no reference experience for the assembly scheme in related fields. If the horizontal assembly is adopted, it is necessary to solve the centering accuracy of the notch and the deviation during the la...
