Description
Technical field
The present invention relates to a kind of technology of noise-reducing, particularly a kind of pump that is used in the field, engineering station such as petroleum gas, internal valve chamber reduces the pump noise reduction canopy of noise effect.
Background technique
Often use the pump equipment such as diesel engine, gear, generator, slurry pump, water injection pump in the field, station of the engineerings such as petroleum gas, the inside of valve chamber.Pump, especially large-scale pump often produces larger noise at run duration.These noises are comprehensively complicated, influence each other, the noise of generation mainly centered by machine room to, with the form of spherical wave to around radiation propagation, have medium and low frequency sound wave characteristics, wavelength is longer, a little less than the directivity, dyingout is slow.Noise usually surpasses the regulation requirement that is lower than 85dB in NBS " industrial enterprise's noise sanitary standard " and " worker of the industrial enterprise hearing protection standard " to the impact in environment and each work position in the pump operating area scope.And because its operation work often is positioned at indoorly, noise has produced long-term noise pollution and harm easily to the personnel that are responsible for operation maintenance.The noise abatement problem of this kind equipment is perplexing relevant unit of operation always in the industries such as petroleum gas.Run unit is generally taked pump equipment is carried out the noise reduction transformation, the operation room factory building is carried out noise prevention processes, is equipped with for the worker measure such as articles for labour protection and reduce noise, yet the effect that these measures are played is more limited.
Summary of the invention
Purpose of the present invention is intended to solve noise that present above-mentioned pump in use produces to the problem of surrounding enviroment impact, and a kind of pump noise reduction canopy that can improve existing pump noise effect is provided.
Purpose of the present invention can realize by following technical solution:
This pump noise reduction canopy comprises the canopy body that is provided with pipeline opening, and described canopy body comprises side Sound insulating layer and end face absorbent treatment.The Main Function of described side Sound insulating layer is the through noise that intercepts pump.The Main Function of described end face absorbent treatment is the reverberation noise that absorbs pump.
Purpose of the present invention can also be opened realization by following technical solution:
Described side Sound insulating layer preferably includes liner plate, sound insulationg board, cotton, the framework body of sound absorption.The effect of described liner plate is to be connected with described framework body, and the described sound insulationg board of support.The effect of described sound insulationg board is reflection and absorbs the through noise of pump, stops noise to leak.The cotton effect of described sound absorption is to absorb the through noise of pump, and noise reduction is to the effect of sound insulationg board.The effect of described framework body is the basic framework that consists of described side Sound insulating layer, the assembling of convenient described side other members of Sound insulating layer.The advantages such as that the combination of the component parts of this described side Sound insulating layer has is simple in structure, easy installation and removal, absorption of noise are effective.Described end face absorbent treatment preferably includes structure and micropore acoustic board.The effect of described structure is to consist of described end face absorbent treatment basic boom, the assembling of convenient described other members of end face absorbent treatment.The effect of described micropore acoustic board is the reverberation noise that absorbs pump, and plays certain thermolysis.The advantage that the combination of the component parts of this described end face absorbent treatment has is simple in structure, the through noise effects of easy installation and removal, obstruct pump is good etc.Described end face absorbent treatment preferably is provided with sound insulation louver window.The effect of described sound insulation louver window is in the reverberation noise that can absorb pump, plays the effect of better heat radiation.Sound insulating layer top, described side preferably is provided with ventilated port, and described ventilated port place is provided with silencing apparatus.The effect that described ventilated port is set is the ventilation and heat performance that improves described canopy body.The effect of described silencing apparatus is the noise that absorbs described ventilated port place.Described ventilated port place preferably is provided with blower fan.The effect that described blower fan is set is further to provide good ventilation and heat for the pump in the described canopy body.Described side Sound insulating layer preferably is provided with soundproof door.The effect that described soundproof door is set is for conveniently entering described canopy body to safeguard the entrance configuration switch function of pump, leaking to guarantee to intercept to make an uproar after closing this entrance.Described blower fan is preferably explosion-proof axial flow fan.Described explosion-proof axial flow fan has that noise is little, the advantage of working stability etc.Described silencing apparatus is preferably impedance muffler.Described impedance muffler have soundproof effect good, the advantage such as be convenient to install and use.The benefit of the pipeline opening of described canopy body is provided with the rubber protection pad.The effect of described rubber protection pad is canopy body and the pipeline gap at the described pipeline opening of sealing place, to reduce noise unofficial biography and described canopy body and the mutual influence of vibration of pipeline.The step that pump is closed in the inside of pump noise reduction canopy preferably includes the integral frame of building described pump noise reduction canopy around described pump, builds other component parts of assembling pump noise reduction canopy after finishing at this framework.The design that this method step can make the surrounding enviroment of the easier realization of described pump noise reduction canopy and pump adapt is convenient to finish installation quality is installed and guaranteed in the sealing of pump.
Beneficial effect of the present invention: owing to by the pump that exceeds NBS in the noise index pump noise reduction canopy is installed; do not affect formation and the work of pump; employed pump noise reduction canopy comprises the component parts such as side Sound insulating layer and end face absorbent treatment; effectively intercept the pump running noises to the particularly impact of operation room of surrounding enviroment, thereby can realize reducing the noise of this pump and protection pump operation maintenance personnel's purpose.So advantage such as that the present invention has is simple and reasonable, reliable, noise reducing is effective.
