Abstract
The utility model relates to the field of compressors, in particular to a ternary-flow impeller of a high-efficiency compressor. The ternary-flow impeller of the high-efficiency compressor is especially applicable to power high-efficiency compressors, chemical engineering high-efficiency compressors and other high-efficiency compressors needing to convey gases. The ternary-flow impeller of the high-efficiency compressor is characterized in that nine main blades and nine splitter blades are welded to a wheel plate and welded to the wheel plate at equal intervals in an isolated mode; the size of the main blades is larger than one third of that of the splitter blades and the main blades are the same with the splitter blades in terms of images; the outer circle ends of lower meridian runner type lines of the main blades and the splitter blades are flush with the outer circle ends of upper meridian runner type lines of the main blades and the splitter blades. The angles of the lower meridian runner type lines are larger than those of the upper meridian runner type lines. The angles of the inner circle ends of the upper meridian runner type lines are 90 degrees and the inner circle ends are connected with the lower meridian runner type lines. By means of the technical scheme, an obvious flow loss source in the impeller is eliminated, thus the ternary-flow impeller can be possessed with good flow performance and low efficiency loss.
Description
Technical field
The utility model relates to compressor field, is a kind of three-dimensional flow impeller of high-efficient compressor.Be specially adapted to electric power, chemical industry and other need to carry the high-efficient compressor of gas.
Background technique
Along with giving priority in industry of the national economy such as China divides at sky, metallurgy, building materials, petrochemical industry, electric power, sewage treatment, the industrial structure is to energy-conserving and environment-protective future development, and its industry equipment is also gradually to energy-conserving and environment-protective future development.Therefore, industrial centrifugal compressor has been proposed towards the new demand of the future developments such as high efficiency, low flow rate, long service life, for ease of maintenaince installation.Traditional compressor impeller Pneumatic design method, has simplified the process of gas flow in impeller, and in low flow rate level, error is very large, and efficiency is generally on the low side, has increased the operating cost of compressor, has greatly wasted the energy.
Summary of the invention
The utility model is intended to overcome above-mentioned defect, and object is to provide that a kind of high efficiency, low noise, security of operation are reliable and stable, the compressor impeller of long service life.
The utility model is achieved in that a kind of three-dimensional flow impeller of high-efficient compressor, it is characterized in that being welded with nine primary blades and nine splitterr vanes on wheel disc, and equidistant being separated by of primary blades and splitterr vanes is welded on wheel disc; The size of primary blades is greater than 1/3rd of splitterr vanes, and its figure is the same; The outer nose circle of the lower meridional channel molded line of primary blades and splitterr vanes and the cylindrical of upper meridional channel molded line are held level with both hands together, the angle of lower meridional channel molded line is greater than the angle with upper meridional channel molded line, and the interior nose circle of upper meridional channel molded line is an angle of 90 degrees and is connected with lower meridional channel molded line.
Owing to having adopted technique scheme, eliminate in impeller significantly flow losses source, thereby obtain good flowing properties, three-dimensional flow impeller that loss in efficiency is low.
Accompanying drawing explanation
Fig. 1 is impeller schematic diagram of the present utility model.
Fig. 2 is impeller sectional view of the present utility model.
Fig. 3 is impeller meridional flow diatom schematic diagram of the present utility model.
In the drawings: 1, primary blades; 2, splitterr vanes; 3, wheel disc; 4, lower meridional channel molded line; 5, upper meridional channel molded line.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
In Fig. 1, Fig. 2 and Fig. 3, on wheel disc 3, be welded with nine primary blades 1 and nine splitterr vanes 2, equidistant being separated by of primary blades 1 and splitterr vanes 2 is welded on wheel disc 3; The size of primary blades 1 is greater than 1/3rd of splitterr vanes 2, and its figure is the same; The outer nose circle of the lower meridional channel molded line 4 of primary blades 1 and splitterr vanes 2 and the cylindrical of upper meridional channel molded line 5 are held level with both hands together, the angle of lower meridional channel molded line 4 is greater than the angle with upper meridional channel molded line 5, and the interior nose circle of upper meridional channel molded line 5 is an angle of 90 degrees and is connected with lower meridional channel molded line 4.
Therefore, the compressor impeller that adopts this Advanced Idea to design, its internal flow is smooth and easy, produces noise low, has and can improve this obvious advantage of overall efficiency.Through CFD checking, impeller of the present invention is under its operating point for design, and polytropic efficiency is up to 93.67%.
