Abstract
The invention discloses a centrifugal fan with dividing channel in volute spiral room with the purpose that whole running status of fan is improved. It is provided with simple structure, less part added and easy machining. The invention comprises volute body, vane wheel, driving part, rectifying part and two and more than two dividing channels in the volute spiral room. Compared with current known centrifugal fan, air flow is leaded in time and does not interfere with each other in the spiral room so as to improve efficiency and increase flow quantity. In the same time it is provided with stable running.
Description
Technical field
The present invention relates to the centrifugal blower field, the volute that particularly relates to a kind of spiral case is established the centrifugal blower of runner.
Background technique
Statistics shows, in the total electricity consumption in the whole nation, is that Pumps ﹠ Fans consumes more than 30%.This shows that Pumps ﹠ Fans occupies an important position in the Chinese national economy construction.The using scope of centrifugal blower in fan-type is the widest.So the present invention relates to the centrifugal blower field.Centrifugal blower has a lot of known advantages, but also come with some shortcomings simultaneously, particularly in the volute of spiral case, air-flow impacts mutually, disturbs, produce vortex, consume a lot of energy in vain, because the generation of vortex region makes that the fluidised form in the volute worsens, air-flow can't smooth and easyly flow out, cause the static pressure in the volute to raise, will strengthen backflow, leakage loss, reduced volumetric efficiency.Because air-flow is in the indoor delay of spiral shell, the chance that friction takes place with the impeller of high speed rotating increases the time lengthening of friction, make energy change harmful heat into, the volute temperature is raise, when containing ignitable dust in the air-flow, very easily cause burning even blast, safe operation is produced hidden danger.
Summary of the invention
In order to overcome the deficiency on the prior art, the invention provides and a kind ofly can effectively improve the indoor air-flow fluidised form of snail shell coiling, improve the overall operation situation of blower fan; Simultaneously simple in structure, it is few to increase parts, and the volute of making the spiral case of easy processing is established the centrifugal blower of runner.
For achieving the above object, the technical solution adopted in the present invention is: provide a kind of volute of spiral case to establish the centrifugal blower of runner, comprise volute body, impeller, transmission part, rectification part, be provided with runner more than two or two at the volute of spiral case.
The inflow port of above-mentioned runner is the center with the impeller center, and layout is centrosymmetric.Runner can use the steel plate manufacturing with material, also can adopt the plastic board manufacturing, the foundation of employing is mainly decided on the character and the operating conditions of the gas carried.
The invention has the beneficial effects as follows:
1, timely dredging flow does not make mutual impact disturb, and improves flow efficiency.
2, airflow smooth, the indoor static pressure of snail shell coiling reduces, and has reduced return loss and leakage loss, improves volumetric efficiency.
3, the chance that rubs between air-flow and impeller reduces, the time shortens, produce heat less, helps safe operation.
Description of drawings
Fig. 1: be the layout schematic representation that volute of the present invention is provided with two runners.
Fig. 2: be the layout schematic representation that volute of the present invention is provided with six runners.
Among the figure: 1. spiral case, 2. impeller, 3. runner, 4. total runner.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
In the drawings, be provided with runner 3 in the volute in the spiral case 1, the layout of runner 3 is the center symmetric arrangement that the impeller center is the center, the air-flow that is thrown away by impeller 2 is imported in the runner 3 in time, take their own roads, do not disturb mutually, flow into total runner 4 swimmingly.For the selection of runner 3 quantity, can be selected according to the blower fan model; As preferably, optional two to six more suitable.When runner 3 usefulness steel plates were made, intensity, rigidity, antifriction performance, heat resistance were all better, can be used for carrying containing dust and the higher gas of temperature.When metal being corrosive gas, must adopt the plastic board manufacturing for conveying.
