Abstract
The utility model discloses a diffuser and a compressor containing the same, and belongs to the technical field of compressors. The diffuser comprises a dorsal disc and blades, wherein a plurality of blades are installed and fixed on the dorsal disc. According to the diffuser and the compressor containing the same, the blades are installed on the dorsal disc in a detachable mode, and thus not only can the amount of finish be decreased, but also processing cost is reduced.
Description
Technical field
The utility model relates to the Compressor Technology field, particularly a kind of Diffuser and comprise the compressor of this Diffuser.
Background technique
Diffuser is a vitals in the centrifugal compressor, and its Main Function is that out air-flow in the compressor impeller is slowed down, and makes kinetic energy convert pressure energy to.Along with the production of present Methods for Series Mechanical Products, different compression types need to be equipped with different Diffusers, and different Diffusers only is that setting angle difference or the number of blade are different.Existing general Diffuser mostly is blade with the Diffuser back of the body dish processing is in the same place, and will so that the Diffuser amount of finish strengthens, and cause processing cost too high like this.
The model utility content
In order to solve the large and higher problem of processing cost of present Diffuser amount of finish, a kind of Diffuser now is provided and has comprised the compressor of this Diffuser.Concrete technological scheme is as follows:
A kind of Diffuser comprises back of the body dish and blade, and wherein, a plurality of described blades installations are fixed on the described back of the body dish.
Preferably, described back of the body dish is provided with the groove that a plurality of and described blade is complementary, and described blades installation is in described groove.
Preferably, be provided with mounting hole one in the described groove, described blade is provided with the mounting hole two corresponding with described mounting hole one, and described blade pass crosses described mounting hole one and described mounting hole two is fixed on the described back of the body dish with pin or bolt.
Preferably, described depth of groove is 1-2mm.
A kind of compressor, described compressor are equipped with above-mentioned each described Diffuser.
Compared with prior art, the Diffuser that technique scheme provides and comprise that the compressor of this Diffuser has the following advantages: by being installed on the Diffuser back of the body dish blade is dismountable, not only can reduce amount of finish, and reduce processing cost.
Description of drawings
In order to be illustrated more clearly in the technological scheme among the utility model embodiment, the accompanying drawing of required use was done to introduce simply during the below will describe embodiment, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the Diffuser back of the body dish front schematic view that provides among the utility model embodiment;
Fig. 2 is the Diffuser back of the body dish axial view that provides among the utility model embodiment;
Fig. 3 is that the Diffuser that provides among the utility model embodiment is installed axial view;
Fig. 4 is the Diffuser front view that provides among the utility model embodiment.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing the utility model mode of execution is described in further detail.
Such as Fig. 1-shown in Figure 4, the utility model embodiment provides a kind of Diffuser, comprises back of the body dish 1 and blade 2, and a plurality of these blades 2 are fixed on the back of the body dish 1.At a plurality of grooves 4 that are complementary with blade 2 of back of the body dish 1 processing, and blade 2 can process separately, also can be processed into one rectangular after again according to the design thickness intercepting, and blade 2 is installed in this groove 4.Specific design is for being processed with mounting hole 1 in groove 4, mounting hole 26 is arranged on the blade 2, mounting hole 26 is corresponding with mounting hole 1, blade 2 is fixed on the groove 4 with pin or bolt 3 by this mounting hole 1 and mounting hole 26, the working depth of groove 4 is about 1-2mm, and the installation of its Leaf 2 is installed according to blade 2 quantity and the angle of diffuser Design.Back of the body dish upper groove 4 faces should fit tightly with 2 realizations of blade in the installation process.
The utility model embodiment also provides a kind of compressor, and this compressor is equipped with above-mentioned Diffuser, and the other parts of compressor can be with reference to prior art, does not do at this and gives unnecessary details.
The disclosed Diffuser of the utility model embodiment and blade pass is crossed pin with the compressor that comprises this Diffuser or bolt is installed on the Diffuser back of the body dish, and can adjust blade quantity and angle according to the design needs, both reduce amount of finish, saved processing cost; The diffuser structure simplicity of design has very strong practicability simultaneously.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
