Abstract

Disclosed is a centrifugal compressor balance disk device. By means of the centrifugal compressor balance disk device, the stress of a rotor is balanced, and the service life of a compressor can be prolonged. The centrifugal compressor balance disk device is composed of partition boards and balance disks. The partition boards include the upper partition board and the lower partition board which are mounted in an interlocking mode; opposite semi-circular notches are formed in the contact surfaces of the upper partition board and the lower partition board correspondingly; circular arc clamping grooves are formed in the positions, corresponding to the semi-circular notches, of the upper partition board and the lower partition board correspondingly and circular arc sliding ways are formed; a plurality of vent holes I are uniformly formed between the right sides of the upper and lower partition boards and the corresponding circular arc sliding ways; the balance disks include the upper semi-annular balance disk and the lower semi-annular balance disk which correspond to each other; corresponding comb-tooth-shaped sealing semi-rings are disposed on the inner walls of the upper balance disk and the lower balance disk correspondingly; circular arc clamping stands corresponding to the circular arc sliding ways are disposed on the outer walls of the upper balance disk and the lower balance disk correspondingly and vent holes II corresponding to and communicating with the vent holes I are formed in the outer walls of the upper balance disk and the lower balance disk correspondingly; and the circular arc clamping stands are located in the circular arc clamping grooves.

Description

Centrifugal compressor balancing frame device
Technical field
The present invention relates to a kind of centrifugal compressor balancing frame device.
Background technology
Centrifugal compressor is to air work by impeller, in the runner of impeller and diffuser, utilizes centrifugal boosting and reduction of speed diffusion action, converts mechanical energy into the pressure energy of gas, and it is in the extensive use of the field such as oil, chemical industry.
In actual use, owing to impeller is subject to the Airflow Exciting-Vibration Force that circumferential asymmetry is even, cause the rotor at impeller place by force unbalance, shorten the service life of compressor.
Summary of the invention
The present invention is to solve above-mentioned technical problem, it is provided that a kind of rotor stress balance, can extend the centrifugal compressor balancing frame device in compressor service life.
The technical solution of the present invention is:
A kind of centrifugal compressor balancing frame device, is made up of dividing plate and balancing frame;
Described dividing plate includes upper spacer and the lower clapboard that make-up is installed, it is respectively equipped with relative semicircle gap with the contact surface place on lower clapboard at upper spacer, it is characterized in that on described upper spacer and lower clapboard corresponding semicircle opening position is respectively equipped with arc neck and forms circular arc slideway, is laid with multiple passage I respectively between the right side and corresponding circular arc slideway of described upper and lower dividing plate;
Described balancing frame includes two corresponding semiorbicular upper balancing frames and lower balancing frame, described upper balancing frame and lower balancing frame inwall are respectively equipped with the comb teeth-shaped of correspondence and seal semi-ring, described upper balancing frame is respectively equipped with the circular arc chuck corresponding with described circular arc slideway and passage II that is corresponding with described passage I and that communicate with lower balancing frame outer wall, and described circular arc chuck is positioned at arc neck.
The invention has the beneficial effects as follows:
During installation, the circular hole that the rotor of centrifugal compressor is formed through upper and lower balancing frame.During work, centrifugal compressor impeller rotates the high pressure draught produced through passage I, in passage II entrance, comb teeth-shaped on lower balancing frame inwall seals in semi-ring, and with from upper, lower clapboard right-hand member is from upper, the lower high pressure draught entered between balancing frame and rotor converges, upper, the stable air film of multi-turn is formed between the rotor of lower balancing frame and Qi Nei, the slit flow between semi-rings and rotor is sealed through two comb teeth-shapeds upwards after, low-pressure end on the left of lower clapboard, this air film greatly reduces the unbalanced Airflow Exciting-Vibration Force of rotor axial, rotor is enable to operate smoothly, extend the service life of compressor.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the structural representation of balancing frame in Fig. 1;
Fig. 3 is A portion enlarged drawing in Fig. 1.
In figure: 1-dividing plate, 2-balancing frame, 3-upper spacer, 4-lower clapboard, 5-semicircle gap, 6-arc neck, the upper balancing frame of 7-passage I, 8-, balancing frame under 9-, 10-comb teeth-shaped seals semi-ring, 11-circular arc chuck, 12-passage II.
Detailed description of the invention
As it can be seen, a kind of centrifugal compressor balancing frame device, it is made up of dividing plate 1 and balancing frame 2;Described dividing plate 1 includes upper spacer 3 and the lower clapboard 4 that make-up is installed, it is respectively equipped with relative semicircle gap 5 with the contact surface place on lower clapboard 4 at upper spacer 3, on described upper spacer 3 and lower clapboard 4, corresponding semicircle gap 5 place is respectively equipped with arc neck 6 and forms circular arc slideway, is respectively equipped with, between right side and the corresponding arc neck 6 of described upper and lower dividing plate 3,4, the passage I7 that multiple circumference is uniform;
Described balancing frame 2 includes two corresponding semiorbicular upper balancing frames 8 and lower balancing frame 9, described upper balancing frame 8 and lower balancing frame 9 inwall are respectively equipped with the comb teeth-shaped of correspondence and seal semi-ring 10, described upper balancing frame 8 and lower balancing frame 9 outer wall are respectively equipped with the circular arc chuck 11 corresponding with described arc neck 6 and passage II12 that is corresponding with described passage I7 and that communicate, and described circular arc chuck 11 is positioned at arc neck 6.
