Description
Technical field
The utility model is related to the technical field of peripheral pump, more particularly, to a kind of noise-reducing peripheral pump.
Background technology
Peripheral pump is exactly that liquid is transmitted with momentum on liquid motion direction to the active force of liquid by rotary blade
Kinetic energy is to realize conveying liquid.The impeller of peripheral pump is first-class thick disk, there is many radial direction vanelets in the both sides of its outer rim,
With there is a prismatic annular channel on the pump case of blade corresponding site, whole runner is divided into suction, two sides of row by a cut water,
Suction respectively with pump, row pipeline are connected.Certain centrifugal force is produced when liquid is turned round with impeller in pump, is outwards got rid of into pump case
In annular channel, and be forced under the limitation of flow channel shape backflow, enter another leaf road below from root of blade again.Mesh
Preceding this traditional peripheral pump can produce the hot-tempered sound of sharp waterpower when work, and this brings great shadow to operating environment
Ring, certain health damage is also caused to workmen.
The content of the invention
The deficiency existed for above-mentioned prior art, the purpose of this utility model, which is to provide one kind and effectively reduces waterpower, hits
The noise of generation is hit, and causes the lower noise in working environment, also certain health care is provided to workmen
Noise-reducing peripheral pump.
To realize above-mentioned purpose, the utility model provides following technical scheme：
A kind of noise-reducing peripheral pump, including the pump housing, the pump housing, which is provided with water inlet one and delivery port one, the pump housing, is provided with pump water
Chamber, pump water cavity is provided with the water inlet two connected between water inlet one by intake tunnel and delivery port one is logical by water outlet
The delivery port two of road connection, is isolated, dividing wall is close to the side of delivery port two between water inlet two and delivery port two by dividing wall
Corner angle be arc chamfering.
The utility model is further arranged to：The axis perpendicular of the water inlet one and delivery port one.
The utility model is further arranged to：The caliber of the intake tunnel is divided into from water inlet one to the direction of water inlet two
Three sections, the caliber of first paragraph inlet channel equal, the caliber of second segment inlet channel from water inlet one to the direction of water inlet two
It is gradually reduced from water inlet one to the direction of water inlet two, the 3rd section of inlet channel is gradually increased from water inlet one to the direction of water inlet two
Greatly.
The utility model is further arranged to：The aperture area of the delivery port two is more than the aperture area of water inlet two.
The utility model is further arranged to：The end face of the dividing wall inclining to the direction of delivery port two by water inlet two
Tiltedly.
By using above-mentioned technical proposal, the technique effect that the utility model is reached is：In the pump housing outlet of peripheral pump
Corner angle of the place by dividing wall close to the side of delivery port two process the chamfering of camber, effectively reduce waterpower and hit making an uproar for generation
Sound, and cause the lower noise in working environment, also provide certain health care to workmen.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is sectional structure principle schematic of the present utility model.

Isolated between 2 15 and delivery port 2 17 by dividing wall 18, corner angle of the dividing wall 18 close to the side of delivery port 2 17 are arc
Chamfering 19.Wherein, the axis perpendicular of water inlet 1 and delivery port 1, the caliber of intake tunnel 14 from water inlet 1 to
The direction of water inlet 2 12 is divided into three sections, and the caliber of first paragraph inlet channel is equal from water inlet one to the direction of water inlet two, the
The caliber of two sections of inlet channels is gradually reduced from water inlet one to the direction of water inlet two, the 3rd section of inlet channel from water inlet one to
The direction of water inlet two gradually increases.In addition, the aperture area of delivery port 2 17 is more than the aperture area of water inlet 2 15, dividing wall
18 end face by water inlet 2 15 to the direction of delivery port 2 17 inclination.
Above-described embodiment is only preferred embodiment of the present utility model, and protection model of the present utility model is not limited according to this
Enclose, therefore：All equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by protection of the present utility model
Within the scope of.
