Description

Pump noise reduction booth

technical field

The invention relates to a noise reduction technology, in particular to a noise reduction shed for pumps used in petroleum and natural gas engineering stations and valve chambers to reduce the impact of noise.

Background technique

Pumping equipment such as diesel engines, linkage machines, generators, mud pumps, water injection pumps, etc. are often used in stations and valve rooms of oil and gas projects. Machine pumps, especially large machine pumps, often produce loud noises during operation. These noises are complex and interact with each other. The noise generated is mainly centered in the machine room and radiates to the surroundings in the form of spherical waves. It has the characteristics of medium and low frequency sound waves, long wavelength, weak directionality, and slow attenuation and disappearance. The impact of noise on the environment and various jobs within the operating area of the pump often exceeds the national standard "Noise Hygiene Standards for Industrial Enterprises" and "Standards for Hearing Protection of Industrial Enterprise Workers" which are less than 85dB. And because its operation is often located indoors, the noise is likely to cause long-term noise pollution and harm to the personnel responsible for operation and maintenance. In industries such as oil and gas, the problem of noise control of such equipment has been plagued by relevant operating units. The operating units generally take measures to reduce noise such as noise-reducing transformation of pump equipment, noise-proof treatment of operating rooms and workshops, and provision of labor protection supplies for employees to reduce noise. However, these measures have limited effects.

Contents of the invention

The object of the present invention is to solve the problem that the noise generated by the above-mentioned motor pump during use affects the surrounding environment, and to provide a motor pump noise reduction shed that can improve the noise impact of the existing motor pump.

The purpose of the present invention can be achieved through the following technical solutions:

The pump noise reduction shed includes a shed body provided with a pipe opening, and the shed body includes a side sound insulation layer and a top sound absorption layer. The main function of the side sound insulation layer is to block the direct noise of the machine pump. The main function of the top sound-absorbing layer is to absorb the reverberation noise of the pump.

The purpose of the present invention can also be realized through the following technical solutions:

Said side sound insulation layer preferably includes liner board, sound insulation board, sound absorption cotton and frame body. The function of the liner is to connect with the frame body and support the sound insulation board. The function of the sound insulation board is to reflect and absorb the direct noise of the machine pump, so as to prevent the noise from leaking out. The function of the sound-absorbing cotton is to absorb the direct noise of the machine pump and reduce the effect of the noise on the sound insulation board. The function of the frame body is to constitute the basic frame of the side sound insulation layer, which facilitates the assembly of other components of the side sound insulation layer. The combination of components of the side sound insulation layer has the advantages of simple structure, convenient installation and disassembly, and good noise absorption effect. The top sound-absorbing layer preferably includes a structure and a microporous sound-absorbing board. The function of the structure is to constitute the basic framework of the top sound-absorbing layer, and facilitate the assembly of other components of the top sound-absorbing layer. The function of the microporous sound-absorbing board is to absorb the reverberation noise of the pump and play a certain role in heat dissipation. The combination of components of the sound-absorbing layer on the top surface has the advantages of simple structure, convenient installation and disassembly, and good effect of blocking the direct noise of the machine pump. The top sound-absorbing layer is preferably provided with sound-proof louvers. The function of the soundproof louvers is to absorb the reverberation noise of the pump and at the same time play a better role in heat dissipation. The upper part of the side sound insulation layer is preferably provided with a vent, and the vent is provided with a muffler. The function of setting the vents is to improve the ventilation and heat dissipation performance of the shed. The function of the muffler is to absorb the noise at the vent. A fan is preferably provided at the vent. The function of setting the fan is to further provide good ventilation and heat dissipation for the motor pump in the shed. The side sound insulation layer is preferably provided with a sound insulation door. The function of setting the sound insulation door is to facilitate entering the shed to maintain the function of setting the switch at the entrance of the pump, so as to prevent the noise from leaking out after closing the entrance. The fan is preferably an explosion-proof axial flow fan. The explosion-proof axial flow fan has the advantages of low noise and stable operation. The muffler is preferably an impedance muffler. The impedance muffler has the advantages of good noise reduction effect, easy installation and use, and the like. The pipe opening of the shed is preferably provided with a rubber pad. The role of the rubber pad is to close the gap between the shed body and the pipeline at the mouth of the pipeline, so as to reduce the noise transmission and the mutual vibration between the shed body and the pipeline. The step of sealing the pump in the interior of the pump noise reduction booth preferably includes building the overall frame of the pump noise reduction booth around the pump, and assembling the pump noise reduction booth on the frame after the construction is completed. other constituent parts. This method step can make it easier for the pump noise reduction booth to realize a design that is compatible with the surrounding environment of the pump, and is convenient for completing the closed installation of the pump and ensuring the installation quality.

Beneficial effects of the present invention: Since the pump noise reduction booth is installed on the pump whose noise index exceeds the national standard, the composition and operation of the pump are not affected, and the pump noise reduction booth used includes a side sound insulation layer and a top surface The components such as the sound-absorbing layer can effectively block the impact of the operating noise of the pump on the surrounding environment, especially the operating room, so as to achieve the purpose of reducing the noise of the pump and protecting the operation and maintenance personnel of the pump. Therefore, the present invention has the advantages of simple and reasonable structure, reliability and good noise reduction effect.
