Abstract
The utility model discloses a spiral case support disassembling device of a multi-shaft centrifugal compressor. The spiral case support disassembling device comprises a flange plate, wherein the thickness of the flange plate is not less than 30 mm, the flange plate is provided with two ring through holes, i.e. an inner ring through hole and an outer ring through hole, the inner ring through hole is formed by three holes which are mutually in 120 degrees, the outer ring through hole is formed by three holes which are mutually in 120 degrees, and two adjacent holes are arranged in the same diameter of the flange plate. According to the spiral case support disassembling device of the multi-shaft centrifugal compressor, disclosed by the utility model, the structure is simple, the use is convenient, the disassembly is easy, the safety performance and the maintenance efficiency of the equipment maintenance are increased, and the labor intensity of workers are reduced as well.
Description
Technical field
The utility model relates to the provision for disengagement of a kind of multi-shaft centrifugal compressor spiral case support.
Background technology
The multi-shaft centrifugal compressor stator is comprised of spiral case, diffuser, the support of type ring, end plate etc.Diffuser is fixed by bolts to one section of spiral case, and it is interference fits that the type ring supports with spiral case, with the sealing of rubber " O " circle, as shown in Figure 1.Compressor operation is after a period of time, because the compressed air water content is large, the type ring support and spiral case between seriously corroded, when causing the air compressor machine maintenance, diffuser, type ring support and are difficult to remove.Sometimes overhaul pincers worker and clash with sledgehammer, there are very large potential safety hazard in equipment and maintainer.For this reason, need research to make a cover type ring and support tool special for dismounting, the one, can improve security and the overhaul efficiency of overhaul of the equipments, the 2nd, reduce workman's labour intensity.
Summary of the invention
For above-mentioned prior art, the utility model provides the provision for disengagement of a kind of multi-shaft centrifugal compressor spiral case support.
The utility model is achieved through the following technical solutions:
The provision for disengagement of a kind of multi-shaft centrifugal compressor spiral case support, comprise ring flange, the thickness of ring flange is not less than 30mm, ring flange is provided with two ring through hole: interior ring through hole and outer ring through hole, interior ring through hole is comprised of three holes that are mutually 120 °, outer ring through hole is comprised of three holes that are mutually 120 °, and two adjacent holes are on the same diameter of ring flange.
Preferably, described interior ring through hole is comprised of three Φ 20 holes that are mutually 120 °, and outer ring through hole is comprised of three M22 screws that are mutually 120 °, ring flange diameter 895mm, ring flange center hollow diameter of a circle 614mm, inner ring diameter 644mm, race diameter 794mm.
Further, described ring flange outer rim is provided with gap, gap degree of depth 50mm, length 500mm.
Preferably, described interior ring through hole is comprised of three Φ 20 holes that are mutually 120 °, and outer ring through hole is comprised of three M20 screws that are mutually 120 °, ring flange diameter 518mm, ring flange center hollow diameter of a circle 286mm, inner ring diameter 316mm, race diameter 482mm.
Described each parameter can be selected different size according to actual conditions.
The using method of multi-shaft centrifugal compressor spiral case support of the present utility model provision for disengagement is:
1, stator end plate is pulled down, with the M22 jackscrew provision for disengagement of the present utility model is installed in stator end.
2, support 3 hangers of inwall welding at the type ring, with M20 * 120 bolts, support 3 Φ 22 holes by the type ring, provision for disengagement is fixed on the type ring supports.
3, pass through stator faces M22 screw with the M22 jackscrew, provision for disengagement and the maintenance of type ring are ejected in the lump.Reach the purpose of the support of dismounting type ring and diffuser.
Multi-shaft centrifugal compressor spiral case support of the present utility model provision for disengagement, simple in structure, easy to use, dismounting had easily both improved security and the overhaul efficiency of overhaul of the equipments, had reduced again workman's labour intensity.
