Abstract
The utility model belongs to the field of compressors, and particularly relates to a centrifugal compressor in the isobutane and butyl rubber fields. The centrifugal compressor comprises a rotor and a stator, and is a quad-stage horizontal subdivision compressor; the centrifugal compressor is totally separated into four stages and eight levels, all the impellers and the corresponding stators form a level, every two levels form a stage, each stage is provided with an air inlet tube and an air outlet tube, and totally, eight air tubes are provided; and air which enters the centrifugal compressor is compressed by each stage, then cooled, and enters the next stage to be compressed. The centrifugal compressor is the quad-stage horizontal subdivision centrifugal compressor, and adopts multistage compression and multistage cooling, the air temperature is enabled not to exceed a set value during the whole compression technological process, and moreover, the mechanical loss, the idle work consumption and the like are reduced. The efficiency of the whole machine is improved by about 7.5%.
Description
Technical field
The utility model belongs to compressor field, the centrifugal compressor in specifically a kind of isobutane and the butyl rubber field.
Background technique
In isobutane and the butyl rubber field, compressor is one of nucleus equipment, because the needs of processing technology, final pressure is higher; And in the process of compression, the temperature of medium must not surpass 90 degrees centigrade, must carry out intersegmental cooling in order to reach requirement, and limit every section compression ratio must not be too high.
This generic request need be used two 2 segmentation horizonally split compressors to link in the past and realize, the method is arranged inconvenience, and floor space is big, the pipeline complex connection, and power loss is big in the transmission process, and overall efficiency is low.
The model utility content
In order to solve the problems referred to above that existing this type of compressor (group) exists, the purpose of the utility model is to provide a kind of four-part form horizontally split centrifugal compressor.
The purpose of the utility model realizes through following technological scheme:
The utility model comprises rotor and stator; Said centrifugal compressor is a four-part form horizonally split compressor.
Wherein: it is four sections that said centrifugal compressor is divided into, and every section is equipped with the air inlet air duct and each one of the air duct of giving vent to anger, totally eight air ducts; The main shaft of said rotor is provided with eight impellers, and the stator that each impeller and this impeller are corresponding forms one-level, and every two-stage is formed one section; Get into gas in the centrifugal compressor after every section compression, gas cools off, get into next section again and compress.
Advantage of the utility model and good effect are:
1. the utility model is the horizontally split centrifugal compressor of four-part form, multistage compression, and every grade of cooling guarantees that in the manufacturing process of whole compression, the temperature of gas is no more than setting value, and has reduced mechanical loss, idle work consumption etc.Overall efficiency improves about 7.5%.
2. the utility model carries out the aeroperformance analysis and optimization to stator component, makes flow losses be reduced to minimum, and stator elements efficient improves 2.5～4.2%
3. the utility model has reduced the usage quantity of power link, has reduced transmission loss, has improved efficient.
4. the stator design of the utility model has improved material and utilization of space.
