Abstract
The utility model belongs to the technical field of high-voltage three-phase asynchronous electric motor fan housings, and relates to an electric motor fan housing, in particular to a high-voltage compact electric motor fan housing with sound absorption wool. According to the technical scheme, the high-voltage compact electric motor fan housing with the sound absorption wool comprises a housing body, and the sound absorption wool wraps the housing body. The housing body is fixed to a machine frame of a three-phase asynchronous electric motor, and when a three-phase asynchronous electric motor works, noise output caused when the three-phase asynchronous electric motor works can be reduced via functions of the housing body and the sound absorption wool. The high-voltage compact electric motor fan housing is simple and compact in structure, convenient to use and process, low in use cost, wide in application range, safe, reliable, and capable of effectively reducing noise of the electric motor.
Description
Technical field
The utility model relates to a kind of motor fan housing, and especially a kind of high-voltage compact motor fan housing with silencing cotton belongs to the technical field of high-voltage three-phase asynchronous motor fan housing.
Background technology
Noise directly affects the healthy of people, too strong or long noise, can make people very painful, feel bad, even make people deaf or dead, noise is one of three large public hazards of modern society's contaminated environment.Motor is one of sound source producing noise, and the industries such as motor You family, business, office and workers and peasants doctor extensively and are in large quantities being applied, closely related with the people's life.Along with social progress, people have proposed more and more higher requirement and restriction to the noise of contaminated environment, especially to all the more so with the household electrical appliance of people's close contact.This respect, advanced country especially payes attention to.The noise of motor is mainly divided into three bulks, one: machinery noise, and friction, shock, imbalance and the mesomerism of motor transhipment part form machinery noise; Its two: electromagnetic noise, the pulsation of magnetic field in motor space, a kind of low-frequency noise that causes stator, rotor and whole electric machine structure and generation of vibration is electromagnetic noise; Its three: aerodynamic noise, during electric machine rotation, on fan and rotor, some protrudes that position produces air to impact and friction forms aerodynamic noise.Generally, general user especially Foreign User can increase noise requirement in agreement, and the principle that people-oriented can require noise numerical value lower than the several decibels of national standard numerical value conventionally.Therefore the noise that, how to reduce high-voltage compact motor is an an urgent demand when front motor development.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of high-voltage compact motor fan housing with silencing cotton is provided, and it is simple and compact for structure, can effectively reduce noise of motor, processes easy to usely, and use cost is low, and wide accommodation is safe and reliable.
The technical scheme providing according to the utility model, the described high-voltage compact motor fan housing with silencing cotton, comprises cover body; The outside of described cover body is enclosed with silencing cotton.
Described silencing cotton is wrapped in the outside of cover body after fixing by steel wire.Between described silencing cotton and cover body, glue line is set.
Described steel wire is provided with fixed leg, and one end of described fixed leg is fixedly connected with cover body after passing steel wire, silencing cotton, after the other end bending of fixed leg, by pad, is connected with steel wire.
Advantage of the present utility model: cover body is fixed in the frame of threephase asynchronous, when threephase asynchronous is worked, by the effect of cover body and silencing cotton, the noise output producing in the time of can reducing threephase asynchronous work, simple and compact for structure, can effectively reduce noise of motor, process easy to use, use cost is low, and wide accommodation is safe and reliable.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is use state diagram of the present utility model.
Description of reference numerals: 1-cover body, 2-glue line, 3-silencing cotton, 4-steel wire, 5-pad, 6-fixed leg and 7-frame.
Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1: in order effectively to eliminate the noise producing when high-tension compact type threephase asynchronous is worked, the utility model comprises cover body 1; The outside of described cover body 1 is enclosed with silencing cotton 3.
Particularly, described silencing cotton 3 is wrapped in the outside of cover body 1 after fixing by steel wire 4.1 of described silencing cotton 3 and cover body arrange glue line 2.By glue line 2, can allow silencing cotton 3 be bonded in the outer surface of cover body 1.
Described steel wire 4 is provided with fixed leg 6, and one end of described fixed leg 6 is fixedly connected with cover body 1 after passing steel wire 4, silencing cotton 3, after the other end bending of fixed leg 6, by pad 5, is connected with steel wire 4.The utility model embodiment is total, and fixed leg 6 is connected and fixed by welding and cover body 1.
As shown in Figure 2: during use, cover body 1 is fixed in the frame 7 of threephase asynchronous, when threephase asynchronous is worked, by the effect of cover body 1 and silencing cotton 3, the noise output producing in the time of can reducing threephase asynchronous work, simple and compact for structure, can effectively reduce noise of motor, process easy to usely, use cost is low, wide accommodation, safe and reliable.
