Abstract
The utility model discloses a noise eliminator of a motor, which comprises a composite shell body and a honeycomb body. The composite shell body is composed of an outer shell board, a noise-absorption material and an inner noise-absorption wallboard; the outer shell board and the inner noise-absorption wallboard form, a hollow cavity body, the noise-absorption material is filled in the cavity body, and the honeycomb body is transversely arranged in the through-flow direction. With simple as well as reasonable structure and convenient assembling/disassembling, the noise eliminator is a special one suitable for a Y-series three-phase asynchronous motor. The noise eliminator is installed at the position of a cover shell at the tail part of the motor and is used for lowering noise of a wind wheel at the tail part, and the honeycomb at the inner part can lower the running noise of the motor; therefore, the noise eliminator can be widely used for the Y-series three-phase asynchronous motor with a rotating speed of more than 1,440 r/m and is particularly suitable for being popularized and applied on the motors of a water pump, a high-pressure fan and the like.
Description
Technical field
The utility model relates to a kind of muffler, particularly a kind of muffler that is used for Y series threephase asynchronous.
Background technology
Y series motor promptly is totally-enclosed self cool mouse-cage type threephase asynchronous, and Y series is general purpose motor, can drive the various plant equipment of no specific (special) requirements, as blower fan, water pump, lathe, mixer etc.The synchronous speed of motor has 3000,1500,1000,750 and 600 rev/mins, Y series threephase asynchronous machine running noises more than per minute rotating speed 1440 changes is at 80dB＜A〉more than, its sound source mainly contains: afterbody wind wheel noise, electromagnetic noise, mechanical vibration noise, groove noise.Wherein the wind wheel noise is the main noise source, therefore, noise of motor refers generally to afterbody wind wheel noise, its noise level 80～95dB, the noise of this progression has reached people's normal life and the able-bodied degree of influencing, therefore, be badly in need of a kind of muffling device that can reduce such motor afterbody wind wheel noise on the market and occur, to stop the noise propagation in space towards periphery.
The utility model content
At above-mentioned the deficiencies in the prior art part, the utility model provides a kind of muffler of the Y of being specifically designed to series threephase asynchronous, can effectively solve the problem that above-mentioned prior art exists.
To achieve these goals, the technical solution adopted in the utility model is: disclose a kind of motor muffler, it comprises combined housing and honeycomb ceramics, described combined housing is made up of Shell Plate, sound-absorbing material and interior sound absorption wallboard, Shell Plate and interior sound absorption wallboard form the cavity of hollow, sound-absorbing material is filled in this cavity, and described honeycomb ceramics is along through-flow direction horizontally set.
As preferably, described honeycomb ceramics is spaced by several conduit walls and forms, and is spaced apart gas channel between the conduit wall;
Further, described conduit wall is the perforated metal of filling sound absorption fiber material in it.
Further, described gas channel is square or circular.
As preferably, described Shell Plate is a metallic plate, and its thickness is 0.7-1mm.
As preferably, the end of described Shell Plate is provided with metal perforated plate or guard, plays dustproof anti-foreign matter and enters inner effect with air-flow.
Compared with prior art, the beneficial effect that this utility model is brought is: this utility model is simple in structure, rationally, tear open, dress is convenient, it is a kind of muffler of the Y of being specially adapted for series threephase asynchronous, this muffler is installed on motor afterbody case place, be used to reduce the noise of its afterbody wind wheel, its inner honeycomb ceramics length equals motor entity diameter, the length of honeycomb ceramics adds upper forepart and motor mating part, total length after the wind collecting section, rear portion is divided is during more than or equal to 1.6 times of motor entity diameter, can reduce more than the motor running noises 18dB, therefore, this muffler can be widely used in the Y series threephase asynchronous of rotating speed more than 1440 rev/mins, be particluarly suitable for pump motor, apply on the high pressure positive blower motor etc.
