Abstract
The utility model discloses a tooth -like transmission centrifugal compressor diffuser belongs to tooth -like transmission centrifugal compressor technical field. The utility model discloses a diffuser body is equipped with a plurality of edges on the diffuser body diffuser body center is the blade of centre of a circle circumference evenly distributed and slant setting, and the profile of blade comprises a straight line and an arc curve end -to -end connection, and profile straight line one side of blade is located near diffuser body inboard, and profile arc curve one side of blade is located and is close to the diffuser body outside, the inlet angle one end of blade is close to the center of diffuser body, the outlet angle one end of blade is close to the outer edge of diffuser body, the inlet angle by 61 degrees contained angles constituteing of straight line and arc curve, the outlet angle by 63 degrees contained angles constituteing of straight line and arc curve. The utility model discloses to the inlet angle, the outlet angle is changed to changed original blade quantity, synthesize efficiency and promote 0.2 0.5%.
Description
Technical field
The utility model belongs to tooth-like transmission centrifugal compressor component technology field, and especially tooth-like with one transmission centrifugal compressor diffuser is relevant.
Background technology
Diffuser is a vitals in centrifugal compressor, and its Main Function is by flow slowing down out in compressor impeller, and makes kinetic energy be converted into pressure energy.For current centrifugal compressor, general using streamline vane diffuser, the inlet angle of blade, the angle of outlet and the number of blade can be on efficiency and produce certain impact.Patent publication No. is that 202851465U discloses a kind of diffuser, including back of the body dish and blade, wherein, multiple described blades are fixed on described back of the body dish, the inlet angle of existing diffuser and the angle of outlet are due to structure improvement the most targetedly, therefore causing its overall efficiency the highest, for this problem, applicant has researched and developed tooth-like transmission centrifugal compressor diffuser to solve this problem.
Utility model content
For the problems referred to above, the purpose of this utility model aims to provide a kind of tooth-like transmission centrifugal compressor diffuser improving comprehensive service efficiency.
nullFor this，The utility model is by the following technical solutions: a kind of tooth-like transmission centrifugal compressor diffuser，Including diffuser body，It is center of circle even circumferential distribution and angularly disposed blade along described diffuser body central that diffuser body is provided with multiple，It is characterized in that，The profile of described blade is connected by straight line and arc curve head and the tail and forms，The profile straight line side of blade is located close to inside described diffuser body，The profile arc curve side of blade is located close to described diffuser outer body，Inlet angle one end of described blade is near the center of described diffuser body，Angle of outlet one end of described blade is near the outer of described diffuser body，61 degree of angles that described inlet angle is made up of described straight line and arc curve，63 degree of angles that the described angle of outlet is made up of described straight line and arc curve.
Use the utility model can reach following beneficial effect: inlet angle, the angle of outlet are changed by the utility model, and change original blade quantity, and overall efficiency can promote 0.2-0.5%.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in detail.
Embodiment: as shown in Figure 1, the utility model includes diffuser body 4, it is center of circle even circumferential distribution and angularly disposed blade 2 along described diffuser body central that diffuser body 4 is provided with multiple, the profile of described blade 2 is connected by straight line and arc curve head and the tail and forms, the profile straight line side of blade 2 is located close to inside diffuser body 4, the profile arc curve side of blade 2 is located close to outside diffuser body 4, inlet angle 3 one end of described blade 2 is near the center of diffuser body 4, the angle of outlet 1 one end of described blade 2 is near the outer of diffuser body 4, 61 degree of angles that inlet angle 3 is made up of straight line and arc curve, 63 degree of angles that the angle of outlet 1 is made up of straight line and arc curve.
Further, blade 2 is fixed on the blade mounting groove of diffuser body 4.
As preferably, blade 2 quantity is 9.
Inlet angle, the angle of outlet are changed by the utility model, and change original blade quantity, and air-flow enters the runner between blade 2 through inlet angle 3, the angle of outlet 1 discharge, and overall efficiency can promote 0.2-0.5%.
Of the present utility model general principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; the utility model is not restricted to the described embodiments; described in above-described embodiment and specification, principle of the present utility model is simply described; on the premise of without departing from the utility model spirit and scope; the utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed the utility model.The utility model claims scope and is defined by appending claims and equivalent thereof.
