Description
Technical field
The utility model belongs to the technical field of centrifugal compressor, namely belongs to the technical field of the multistage centrifugal pump compressing or find time, and is specifically related to a multistage centrifugal compressor vertically split.
Background technique
Centrifugal compressor is widely used in petrochemical industry, metallurgical industry and other industrial technical field as pneumatic machinery, when designing centrifugal compressor, must consider many-sided factor, as reduced cost of production; Improve compressor operating efficiency.
The shell of current centrifugal compressor adopts the structure of casting usually, and this structure makes body heavy, and needs large size machine tool to process, and especially for Large centrifugal compressors, problem seems more outstanding.
Chinese patent ZL200480039764.6 discloses one " multistage centrifugal compressor and installation method thereof ", and its multistage centrifugal compressor is provided with can the container of horizontal opening, comprises lower tank and up-per semi-tank.Obviously, this is the centrifugal compressor that a kind of level splits.Chinese patent ZL200480032608.7 also discloses one " multistage centrifugal compressor ", is also the structure that employing level splits.
The structure that centrifugal compressor level splits, is convenient to mounting or dismounting and maintenance, is really subject to the welcome of user.But, when the output pressure (i.e. exhaust pressure) of compressor is too high, the danger of just implicit explosion, therefore this structure can only be applicable to the manufacture of the compressor of low-voltage and medium voltage usually.
Model utility content
The shortcoming of the centrifugal compressor that the design people splits for level, proposes a kind ofly to be suitable for the vertical fractionation structure of high pressure compressor and the multistage centrifugal compressor of tubular construction.。
The multistage centrifugal compressor of a kind of vertical fractionation of the present utility model, comprises casing, dividing plate, impeller, Balance disc, thrust disc, rotatingshaft, intake duct, Diffuser, return channel, sealing, it is characterized in that:
(1) casing is a horizontal cylinder being arranged on the both ends open on support;
(2) multiple impeller and baffle interval are installed on the rotating shaft in order;
(3) Diffuser is fixed on dividing plate periphery in impeller outer end;
(4) thrust disc and Balance disc are fixed on and turn the tip of the axis;
(5) two ends of rotating shaft be provided with two with the cover plate of casing cylinder close fit.
The multistage centrifugal compressor of vertical fractionation of the present utility model, is characterized in that: be mounted with compressor bearing below horizontal cylinder; Its two ends are designed with sucking pipe and outlet pipe respectively.
The multistage centrifugal compressor of vertical fractionation of the present utility model, is characterized in that: multiple impeller can be divided into several groups; Can arrange by forward between two groups of impellers; Also can oppositely arrange.The chemical reaction of two kinds of gases is conducive to when oppositely arranging.
