Embodiment 1

[0028] See attached Figure 1~4 , the one-side fixed and rotatable super large centrifugal compressor impeller vertical assembly device provided by the present invention includes a stator 1 and a rotating shaft 5, the rotating shaft 5 is connected to the stator 1, and the large centrifugal impeller rotor main shaft 2 can rotate with the rotating shaft 5 as the center of rotation, This enables the rotor main shaft 2 of the large centrifugal impeller to gradually change from the angle between the axis and the horizontal plane of 0° to the angle between the axis and the horizontal plane of 90°.

[0029] The one-side fixed and rotatable super large centrifugal compressor impeller vertical assembly device provided by the present invention includes a stator 1 and a rotating shaft 5, the rotating shaft 5 is connected to the stator 1, and the large centrifugal impeller rotor main shaft 2 can rotate around the rotating shaft 5, The large centrifugal impeller rotor main shaft 2 can grad...

Embodiment 2

[0066] Different from the vertical assembly device for super-large centrifugal compressor impeller fixed and rotatable on one side provided in Embodiment 1 of the present invention, the vertical assembly device for super-large centrifugal compressor impeller fixed and rotatable on one side provided in Embodiment 2 of the present invention Among them, the large centrifugal impeller rotor main shaft 2 is fixedly connected to the rotating shaft 5, and the rotating shaft 5 and the stator 1 form a rotating pair.

[0067] Specifically, the stator 1 includes a base, a pair of connecting ears 4, and the pair of connecting ears 4 are respectively fixedly connected to both ends of the base, the bottom end 8 of the rotor main shaft 2 of the large centrifugal impeller is fixedly connected to the shaft sleeve 6, and the rotating shaft 5 is fixedly connected to the The axle sleeve 6, the rotating shaft 5 and the connecting ear 4 form a revolving pair.

Embodiment 3

[0069] Improvements are made on the basis of the one-sided fixed and rotatable ultra-large centrifugal compressor impeller vertical assembly device provided in Embodiment 1 or Embodiment 2 of the present invention, and the unilaterally fixed and rotatable ultra-large In the centrifugal compressor impeller vertical assembly device, the lengths of several connecting rods 11 can be adjusted. In this embodiment, the number of connecting rods 11 is 4, which are respectively connected to four points of the central sleeve. By adjusting the lengths of the 4 connecting rods 11, the axis of the large centrifugal impeller rotor main shaft 2 can be ensured. Exactly 90° angle with the horizontal plane.

Abstract

The invention discloses a one-side fixed and rotatable super large centrifugal compressor impeller vertical assembly device, which belongs to the technical field of workpiece fixing or positioning. It includes a stator and a rotating shaft, the rotating shaft is connected to the stator, and the main shaft of the large centrifugal impeller rotor can rotate around the rotating shaft, so that the main shaft of the large centrifugal impeller rotor can gradually change from the angle between its axis and the horizontal plane at 0° to the angle between its axis and the horizontal plane 90°, after the large centrifugal impeller rotor is in a vertical state, keep the main shaft of the large centrifugal impeller rotor at an angle of 90° between its axis and the horizontal plane, and after the secondary impeller is heated, hoist it into the main shaft. After the impeller is completely cooled, use the crane to level the main shaft. After the rotor is dynamically balanced, the first-stage impeller is installed, and the assembly process is the same as above. The assembly device solves the difficult problem of vertical assembly of large centrifugal impellers, improves the assembly accuracy, and ensures the product production cycle. A feasible scheme is provided for the vertical assembly of impellers of large rotor compressors.

Description

technical field [0001] The invention relates to the technical field of workpiece fixing or positioning, in particular to a vertical assembling device for a super large centrifugal compressor impeller fixed and revolvable on one side. Background technique [0002] Due to its advantages of high efficiency and low operating costs, air separation units are gradually being widely used in new coal chemical plants such as coal-to-oil, coal-to-natural gas, coal-to-olefins, and coal-to-aromatics. However, with the enlargement of the air separation unit, the technical parameters are more complicated, and the process assembly requirements are becoming more and more sophisticated. The main shaft of the 100,000 air separation rotor consists of three sections connected by bolts. In order to avoid the excessive static load of the tension bolt, it is not allowed to lift the main shaft vertically from the ground during the assembly process. Therefore, when carrying out vertical assembly to...
