Abstract
The utility model discloses a composite plate type isolator of a multistage compressor. The utility model designs a fire-new sound insulation cover under the condition of no any change of the structure of a compressor by using the mechanism of viscous loss generated by the effect of air molecular vibration caused by sound waves entering micropores. The utility model can effectively isolate noise. When a whole air compressor is put into the sound insulation cover, noise can be effectively controlled to be not propagated outside and the influence of the noise for environment is reduced. The appearance of the sound insulation cover is in square steel plate structure. The inner face of a steel plate is added with ribs and is attached with rubber damping materials with the thickness of 7 mm in consideration of the effect of resonance and coincidence. The inner surface of the steel plate is provided with super thin glass wool with the thickness of 50 mm. The sound insulation cover and machines uses a vibration insulating and treating measure. A forced ventilation device is arranged for avoiding the temperature rise of machines in the sound insulation cover, the sound insulation cover can effectively reduce noise by about 50dB through the certification of experiments and the mute of the air compressor is achieved.
Description
Technical field
The utility model relates to a kind of sound arrester, relates in particular to a kind of composite board type sound arrester of multipole piston type air compressor.
Background technique
Air compressor is a kind of high equipment of making an uproar, and its noise frequency is relatively broader, and general influential main crest frequency is between 20～2000Hz.The noise source of compressor is a kind of comprehensive noise source, and it comprises three types of mechanical noise, air power noise and electrical noises.The main cause that produces mechanical noise is the existence in motion gap, the knock of air inlet and exhaust valve valve block.Aerodynamic noise mainly is the noise that produces owing to compressor air suction, exhaust.Thereby high velocity air produces a large amount of eddy current and forms the continuous medium-high frequency pneumatic noise of wide band when the air valve passage, simultaneously owing to the discontinuity of air-breathing exhaust, also can produce the microseismic noise of air-flow.The intense noise that produces when compressor normally moves is worked the operator for a long time in high-noise environment, hearing is damaged, and healthyly is affected in various degree.Therefore noise control just seems particularly necessary.
Noise of Air Compressor mainly is made of mechanical noise and air power noise.Therefore the control of compressor noise is many at present carries out from Control of Mechanical Noise, two aspects of air power noise control.Mechanical noise control relates to a lot of aspects factor, mainly starts with from control vibration, bump and their transmission at present.The impact, the raising balance quality that reduce parts in addition also are effective measures.Air power noise control then by compressor is advanced, the air-flow path of exhauster system, and the chamber that links to each other with these passages carries out rationality design and realizes.These two kinds of noise control methods all can increase production cost of products, and noise reduction is also limited.
The model utility content
The purpose of this utility model is by a kind of composite board type sound arrester of multipole piston type air compressor is provided, device with effective partition noise, whole air compressor put into acoustic hood, can control the unofficial biography of noise effectively, reduce the influence of noise surrounding environment.
The utility model is to adopt following technological means to realize.
A kind of composite board type sound arrester of multistage compressor is equipped with multistage compressor above gas holder, in a side of multistage compressor motor is installed; Fastening has the composite board type sound arrester in the outside of compressor, motor and gas holder, in a side of motor, has the hole that ventilating fan is installed; This composite board type sound arrester is for being fastened on the outer field plank frame of compressor, and its outermost is a steel plate structure; Be fitted with rubber damping material on the rib in the described inner surface of steel plate, be provided with Mild Steel Expanded Sheets, between Mild Steel Expanded Sheets and rubber damping material, be provided with glass wool at the opposite side of described composite board type sound arrester.
One side of aforesaid sound arrester offers circular hole, on this circular hole ventilating fan is installed.
Further add rubber sheet gasket between aforesaid sound arrester and the base.
The utility model compared with prior art has remarkable advantages and beneficial effect:
A kind of composite board type sound arrester of multistage compressor is arranged on the outside of compressor, and this device is for being fastened on the outer field plank frame of compressor, and its outermost is a steel plate structure; Be fitted with rubber damping material on the rib in the inner surface of steel plate, be provided with Mild Steel Expanded Sheets, between Mild Steel Expanded Sheets and rubber damping material, be provided with glass wool at the opposite side of described composite board type sound arrester.This structure can effectively be cut off the device of noise, and whole air compressor put into acoustic hood, can control the unofficial biography of noise effectively, reduces the influence of noise to surrounding environment, has realized quietization of air compressor.
