Abstract
The utility model relates to the field of impellers and particularly relates to a high-efficiency and high-pressure-head three-dimensional flow impeller. The three-dimensional flow impeller is characterized by being welded from blades and a wheel disk, wherein the wheel disk is provided with taper holes; the periphery of the wheel disk is provided with a different-thickness disk; and the pressure surface of each blade and the surface of each weld joint are sprayed with a nickel-chromium alloy powder layer which is 0.2-0.3mm in thickness. Due to the adoption of the technical scheme, the three-dimensional flow impeller has the advantages of high efficiency, high pressure head and low manufacturing cost; and the impeller is of a semi-open type and is convenient to process and manufacture.
Description
Technical field
The utility model relates to the impeller field, is a kind of efficient high-pressure head three-dimensional flow impeller.
Background technique
Along with the application of ternary flow technology in fan design is more next extensive approximately, adopt the CFD technology that the turbomachine interior flow field is analyzed, the impeller of designing efficiently and accurately has become the development trend of fan design.Traditional monobasic design method has been simplified the process of gas flow in the impeller level, and often error is very large in than level at high speed and high pressure, and its efficient is lower, and the not high and impeller of pressure head adopts that to mill processing and fabricating cost processed very high.
Summary of the invention
The purpose of this utility model is to provide that a kind of efficient is high, pressure head is high, the three-dimensional flow impeller of low cost of manufacture.
The technical solution of the utility model is: it is characterized in that impeller is that blade and wheel disc are welded, at wheel disc taper hole is arranged, the periphery of wheel disc is uniform thickness dish not, and at pressure side and the face of weld spraying plating nichrome powder layer of blade, thickness is 0.2～0.3m.
Owing to adopt technique scheme, efficient is high, and pressure head is high, low cost of manufacture, and this impeller is semi-open type, is convenient to manufacturing.
Description of drawings
Fig. 1 is impeller schematic representation of the present utility model.
Fig. 2 is impeller sectional view of the present utility model.
Fig. 3 is impeller nichrome powder layer schematic representation of the present utility model.
In the drawings: 1, blade; 2, wheel disc; 3, taper hole; 4, uniform thickness dish not; 5, nichrome powder layer.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
In Fig. 1, Fig. 2 and Fig. 3, impeller is that blade 1 and wheel disc 2 are welded, and at wheel disc 2 taper hole 3 is arranged, and the periphery of wheel disc 2 is uniform thickness dish 4 not, at pressure side and the face of weld spraying plating nichrome powder layer 5 of blade 1, thickness 0.2～0.3mm.
The material of blade 1 is Precipitation-hardening Stainless Steel FV520B, and the material of wheel disc 2 is 15MnNiCrMoV, all have anticorrosion about, weld seam adopts the FV520B welding rod special for special to be welded; Blade 1 outlet is radial, and exit installation angle is 90 °, and more about 20% than the energy head height of general backward bent vane, impeller diameter reduces in identical energy head situation, thereby the spiral case radius also reduces, and greatly reduces cost; The design of blade 1 inlet part wind-guiding section meets aerodynamics through the emulation of three-dimensional pneumatic software simulation, can reduce inflow Mach number, raise the efficiency, and the stress that this structure can reduce blade 1 inlet is concentrated.
At wheel disc 2 taper hole 3 is arranged, the mounting or dismounting that are conducive to impeller are convenient; Simultaneously the periphery of wheel disc 2 is uniform thickness dish 4 not, has alleviated impeller weight, has guaranteed again the structural reliability of impeller.
At blade 1 pressure side and face of weld spraying plating nichrome powder layer 5, thickness 0.2～0.3mm has anticorrosion, antiwear effect, the working life of greatly improving impeller.
