I. Introduction
With the continuous development of people's living standard, noise has become to harm human health is one of the major sources of pollution and strong noise on the human body will have a certain degree of harm, so the noise control has become an important part of environmental governance. In the face of the increasingly serious noise pollution, our company has been increasing its investment in science and technology, and has formed a complete set of scientific management system, which has been proved to carry out the scientific management system.
Two, product description
Our company noise and vibration control engineering projects are the main products:
1, sound insulation cover
Sound insulation cover adopts a totally enclosed assembly type structure, it is the noise source cover in a smaller space, partition noise to the external transmission of a control measure; due to the characteristics of each sound source, control requirements, the use of the environment is not the same, so often it requires according to the scene into the design scheme.
The type of sound insulation board, sound insulation door, observation window and frame of the frame can be disassembled and assembled, which has the advantages of convenient assembly and disassembly, convenient maintenance operation and so on.
Sound insulation cover at the same time, the installation of ventilation and cooling device and air inlet, exhaust muffler, etc., can guarantee the normal operation of the equipment.
Sound insulation cover can be used for all generators, motors, fans, compressors, pumps, punching machine, sawing machine, air conditioning, power plants and mines ball grinding coal machine and high noise of mechanical equipments, reduce the equipment to the surrounding radiation noise energy to the environment pollution, and has the advantages of compact structure, convenient assembly, sound insulation effect is good wait for a characteristic absorption.
2, sound insulation screen
The sound insulation barrier is a sound absorbing material as the core material, and the acoustic components are assembled into a suction and sound barrier. Acoustic elements can be processed into a louver, perforation type, micro perforated and slotted hole and several kinds of ceiling, insulation acoustic units. Sound barrier is arranged on the noise source and the protected areas between acoustic baffle, its role is blocked from a sound source and by the sound of the direct sound, and the sound diffraction as little as possible, so that in the acoustic shadow inside the equipment, buildings and environment protected.
For highway, high-speed railway, elevated road traffic noise control. The control of noise in the business world, workshop, equipment, etc..
3, sound insulation door, window
Soundproof door series single sound insulation valve, double sound insulation door, sound insulation door, large soundproof door by door filled in the cavity of the centrifugal glass cotton, damping composite ceiling insulation material and structure, sound insulation door in each frequency band has good sound insulation performance; according to user requirements and the actual situation in the field, but also design and production of the special requirements of sound insulation door. The sound insulation window has a single and double glazing windows are standardized, series.
4, sound insulation felt
The sound insulation mat is a kind of high density EPDM three yuan, after the wet heat, extrusion effect of felting a rubber sheet material. The product quality is stable and the process condition is controlled conveniently, and has good effect of sound insulation. Noise insulation blanket EPDM rubber has physical properties can not change the characteristics, material is qualitative light, ultra thin, soft, tensile strength, black finish, with good resilience, suction shock and insulation, heat insulation and sound insulation properties. Under the conditions of high temperature and low temperature should not be broken and become soft, soundproof felt performance can always maintain the same sound insulating properties, the characteristics of the viscoelastic properties of the rubber can ensure the soundproof felt in the processing of airborne noise and impact noise with excellent insulation properties.
5, absorption body
The space absorption body has the advantages of high absorption efficiency, light weight, easy to install and so on. It is suitable for the improvement of the acoustic quality of the theater, cinema, gymnasium, auditorium, conference room and so on. Space absorber shape can be divided into plate, plate shaped, spherical, cylindrical, conical, cylindrical etc.. The room with noise source is generally used to control the noise source of the room, which is 5~6dB (A) and the highest 10dB (A).
6, shock absorber
Shock absorber is an elastic support component, which is a kind of independent, self - forming device which is manufactured by special design. The most common shock absorber is divided into metal spiral spring shock absorber, rubber shock absorber, metal wire mesh shock absorber, metal and rubber composite shock absorber, air spring shock absorber.
Company design, production, installation of noise and vibration control project, has been in the metallurgical, electric power and other occasions received a good effect. The company of noise control engineering, from the scheme design, equipment manufacturing, construction, installation and commissioning of the implementation of one-stop service.
