Abstract
The utility model relates to a noise-reducing fan cover for a motor, in particular to a low-noise fan cover for a high-pressure compact type motor. The fan cover comprises a first noise-reducing end cover (1) connected with a motor, wherein a cooling fan (2) is fixed at the center position at the outer-side end of the first noise-reducing end cover, a ring-shaped noise-reducing structure body (3) is arranged between the outer periphery of a fixed frame of the cooling fan and a housing wall of the first noise-reducing end cover, a connecting place between a housing outer wall enclosing the cooling and an outer wall enclosing the ring-shaped noise-reducing structure body is provided with a cylindrical noise-reducing body (5), the peripheral space of the cylindrical noise-reducing body is provided with a cylindrical second noise-reducing end cover (6) of which the end is sealed and the open end is fixedly connected with the ring-shaped noise-reducing structure body, and an air inlet (4) is arranged on a housing of a corresponding end between the second noise-reducing end cover and the cylindrical noise-reducing body. A curve road is added on the design of an air channel, a noise-reducing principle is abundantly used, and the noise is abundantly absorbed when being propagated along with the change of the length and the cross section of the air channel, so that the noise can be effectively reduced. The noise-reducing fan cover is simple in structure and reasonable in design.
Description
Technical field
The utility model relates to a kind of motor noise-reducing fan housing, particularly relates to a kind of high pressure compact(ing) machine low noise fan housing.
Background technology
The motor fan housing of conventional design does not have noise eliminator, and is relatively poor for the absorption of noise of motor, and the fan housing noise is bigger; And old-fashioned noise reduction end shield air channel is narrow, and is bigger to electric machine temperature rise influence, increases electric machine temperature rise 3-5K, and simultaneously, noise elimination structure only simply stops air outlet, and is relatively poor for the absorption of noise of motor, only can reduce about 5 decibels the effect price differential; And the manufacture craft property and the versatility of common fan housing and noise reduction fan housing are relatively poor.
The utility model content
The utility model is not enough to prior art, proposes a kind of high pressure compact(ing) machine low noise fan housing.
The technical scheme that the utility model adopted:
A kind of high pressure compact(ing) machine low noise fan housing; Comprise the cylindrical shape first noise elimination end shield (1) that is connected with motor; Said cylindrical shape first noise elimination end shield (1) the outboard end center is fixed with cooling fan (2); Be provided with annular noise elimination structure body (3) between the housing wall of the fixed frame excircle of said cooling fan (2) and the cylindrical shape first noise elimination end shield (1); Be connected with cylindrical shape muffler body (5) around the casing outer wall of said cooling fan (2) and the outer wall of said annular noise elimination structure body (3); Peripheral space at said cylindrical shape muffler body (5) is provided with the cylindrical shape second noise elimination end shield (6) that closed-end, opening end and annular noise elimination structure body (3) are fixedly connected, and offers air inlet (4) on the housing of said cylindrical shape second noise elimination end shield (6) and cylindrical shape muffler body (5) corresponding end.
Described high pressure compact(ing) machine low noise fan housing, cylindrical shape muffler body (5) is that dismountable activity is fixedly connected with the cylindrical shape second noise elimination end shield (6) and the connected mode of annular noise elimination structure body (3).
Described high pressure compact(ing) machine low noise fan housing, the cylindrical wall and the closed end of the cylindrical shape second noise elimination end shield (6) are equipped with the deadener layer.
Described high pressure compact(ing) machine low noise fan housing, the air inlet of offering on cylindrical shape second noise elimination end shield (6) housing (4) is four, per two in second noise elimination end shield (6) the housing upper and lower position symmetric arrangement respectively.
The useful good effect of the utility model:
1, the utility model high pressure compact(ing) machine low noise fan housing; The noise elimination end shield has increased Qu Lu in air channel design, made full use of noise-cancelling theory, through air channel length and cross section variation; Noise fully is absorbed in the air, and then effectively reduces noise.Be particularly suitable for high pressure compact threephase asynchronous, can effectively reduce about 10 decibels of noises.
2, the utility model high pressure compact(ing) machine low noise fan housing is simple in structure, reasonable in design, sets up the structural design of dismounting, has interchangeability and versatility with common end shield, has improved manufacture craft property.
