Description

TECHNICAL FIELD

[0001] The present application belongs to the field of compressor regulating mechanism, in particular to a guide vane regulating mechanism alignment tool and method. BACKGROUND

[0002] The guide vane regulating mechanism can adjust the rotation law of the guide vane, and further adjust the working range of the compressor, and improve the surge margin of the compressor. The guide vane regulating mechanism usually includes a driving device, a linkage ring and a rocker arm, etc. The linkage ring is installed on the outer periphery of the casing, the driving device drives the linkage ring to rotate on the casing, and then the linkage ring drives the rocker arm to rotate, finally realizing the angle adjustment of the blades at each stage. During the rotation of the guide vane, if the linkage ring is eccentric, the guide vane regulating law will be inaccurate, and the guide vane will be stuck, which is difficult to rotate. Therefore, it is particularly important to ensure that the linkage ring is concentric with the casing axis.

[0003] In the prior art, when adjusting the concentricity of the linkage ring and the casing, a limiting device is usually supported in the circumferential direction of the linkage ring. After assembly, whether the linkage ring and the casing are concentric is determined by measuring the distance between the linkage ring and the casing limiting device. However, there is no tool to ensure the concentricity of the linkage ring and the casing during assembly, and whether the linkage ring and the casing are concentric can only be determined by detection after assembly. If the linkage ring is eccentric, it needs to be disassembled and reassembled, which is extremely low in installation efficiency. Moreover, after installation, the distance between the linkage ring and the casing at different circumferential positions needs to be measured manually with a graduated scale, and the reading is visually observed. The accuracy of the graduated scale is low, and the visual reading error is large. SUMMARY

[0004] In view of the above problems, the present application provides a guide vane regulating mechanism alignment tool, which comprises an alignment ring, a plurality of fixed plates are uniformly distributed on one side of the alignment ring, a plurality of clamping jaws are uniformly distributed on the side of the alignment ring away from the fixed plates, a puller rod is provided on the fixed plate, a casing structure is clamped on the inner ring of the alignment ring, a linkage ring is sleeved on the casing structure, an adjusting piece in contact with the casing structure is provided on the linkage ring, a fixing piece is provided on the casing structure, the end of the fixing piece away from the casing structure is in contact with the linkage ring, and the clamping jaw is inserted between the linkage ring and the casing structure.

[0005] Further, the alignment ring is an integral ring.
