Embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Fig. 1 ~ 3, the utility model mainly comprises rectifier lamp 1, damping net 2 and honeycomb rectifier 3, rectifier lamp 1 inwall welding honeycomb rectifier 3, and honeycomb rectifier 3 one sides are provided with the multilayer damping net 2 that is welded on rectifier lamp 1 inwall.
On described honeycomb rectifier 3 end faces, be covered with multiple orthohexagonal rectification through holes 4, multiple rectification through holes 4 are cellular and are uniformly distributed, and between multiple rectification through holes 4, are not communicated with mutually, mutually isolated.
Described damping net 2 is formed by connecting by multiple transverse steel wire 5 and multiple longitudinal steel wires 6 parallel to each other, that be equally spaced parallel to each other, that be equally spaced, and multiple transverse steel wire 5 and multiple longitudinal steel wire 6 are orthogonal.Between multiple transverse steel wire 5 and multiple longitudinal steel wire 6, form multiple damping through holes 7.
In embodiment as shown in Figure 1, the diameter of honeycomb rectifier 3 is D, and the apothem of orthohexagonal rectification through hole 4 is d1, and the scope of d1 is 0.01D ~ 0.03D.The width of honeycomb rectifier 3 is L1, and the scope of L1 is 8d1 ~ 15d1.
Damping net 2 is generally 3 ~ 5 layers, and the spacing between multiple damping nets 2 is L2, and L2 is more than or equal to 0.2D.A damping net 2 that approaches most honeycomb rectifier 3 is L3 to the spacing of honeycomb rectifier 3, and L3 is identical with L2.The order scope of counting of damping net 2 is 18 order ~ 30 orders.Transverse steel wire 5 is identical with the thickness of longitudinal steel wire 6, and scope is 0.2 mm ~ 0.5mm.
Working principle of the present utility model is: when work, disorderly air-flow enters in rectifier lamp honeycomb rectifier one side is set, and first passes through honeycomb rectifier.Orthohexagonal rectification through hole on honeycomb rectifier end face is large broken reformation of whirlpool in stream in the future, little whirlpool after fragmentation is after over commutation through hole, experience sufficiently long rectifier lamp, disorderly air-flow can be reformed in order, the tangential velocity of eliminating air-flow, makes the flow direction of air-flow all consistent with pipeline center.Air-flow experience multilayer damping net subsequently, damping net produces retardance to air-flow, is characterized in that the flow velocity of air-flow is faster, and blockage effect is more obvious.Like this, the air-flow group that normal velocity is large, blocks also greatly, and the pressure loss is just large, and pressure is just less than by the average gas pressure of air-flow after damping net, and air-flow just needs deceleration like this, and the speed of air-flow can be converted into pressure energy.Otherwise the air-flow group that normal velocity is little, blocks littlely, the pressure loss is also little, and pressure is just greater than by the average gas pressure of air-flow after damping net, and air-flow will accelerate like this, and unnecessary pressure energy is converted to speed energy.With this, the damping net normal velocity that just effectively air-flow is rolled into a ball is adjusted evenly.
The utility model arranges multilayer damping net after honeycomb rectifier, and the tangential and normal velocity of the air-flow of simultaneously adjusting, improves the uniformity in flow field greatly; Improve the precision that blower fan is measured, avoid air turbulence can have a negative impact to blower fan.
