1. Introduction

 

Generating sets, air conditioners, air compressors, or other moving machinery or other sound sources produce a lot of noise, with a sound value of more than 118 decibels, causing serious environmental pollution and affecting people’s normal work and life. Destroy the body's physical and mental health Our company is the muffler engineering expert who turns these sound sources into dumb.

 

2. Noise control scope

 

1. Industrial production sites such as generator room, air compressor room, central air-conditioning room, industrial refrigeration room, and sports machinery room.

2. Noise control of electromechanical equipment in high-noise production workshop.

3. Karaoke halls, opera houses, office buildings and other cultural and entertainment venues.

4. High-demand ultra-quiet, low-noise or no noise, laboratory, scientific research room, etc.

 

3. Technical requirements for noise reduction engineering of generator room

 

1. Air intake system: each generator set needs a lot of fresh air when it works, which is mainly used for diesel engine combustion and electric bulb cooling.

2. Exhaust system: When the diesel engine is working, a large amount of heat is generated. This heat must be pumped (discharged) out of the engine room to ensure that the temperature of the engine room does not exceed 50 degrees and provide a normal working environment for the generator set.

3. The noise reduction engineering of the engine room must refer to the scientific and technical parameters such as the air demand, exhaust gas emission, and heat dissipation requirements of the diesel generator set to design a reasonable air intake and exhaust area.

 

4. Introduction to the principle of noise reduction in generator room

 

The noise control project of Yongdaxing Company adopts the principle of treating both symptoms and root causes, from the entrance and exit of the engine room, the air intake system of the diesel engine, the cooling and exhaust system of the water tank and the exhaust system of the exhaust smoke pipe to muffling, sound absorption, vibration reduction, sound insulation, etc. In terms of design and construction, effective and comprehensive treatment of the various ways of noise from the diesel generator room spreading out, limiting the noise in the engine room, and dividing the noise to be discharged outside the engine room, breaking down each, and completely eliminating it. According to user requirements, sound absorption and sound insulation measures can be taken on the roof and walls of the engine room to reduce noise in the engine room. To ensure that the room temperature and diesel engine working temperature will not rise, forced ventilation and exhaust measures shall be taken. The fresh air needed by the generator is replenished in time, and the dirty and hot air is discharged in time. The company installs sound-absorbing panels, sound-absorbing films, and shock-absorbing films in the air inlet and exhaust channels. The installation of a second-level silencer in the exhaust pipe has won unanimous praise from users for its technical content, silencer effect and degree of specialization.

        The sound-absorbing duct is set to silence the noise to minimize the noise. The outside of the sound-absorbing duct is a brick wall structure and the inside is a sound-absorbing panel.

 

5. Service tenet of Yongdaxing Company:

 

       "Strict compliance with standards, scientific design, careful construction, low cost, and high-quality after-sales service" is the service tenet of Shenzhen Yongdaxing Company. We will send professional engineers to inspect the site according to the specific layout of the computer room to provide users with the best design plan. Shenzhen Yongdaxing Company will provide two-year free warranty for noise reduction projects and provide permanent services.

1. After the project is completed, compare the equipment engineering drawings and conduct on-site training and instruction to your equipment manager (person in charge) and operation exercises.

2. Perform quality follow-up service once a month, notify Party A in time if hidden dangers are found, and deal with it according to Party A's requirements.

3. Establish complete equipment operation and maintenance data in the computer to facilitate service tracking and improve maintenance efficiency. Whenever a failure occurs, Party B will send someone to the scene within 12 hours after receiving the failure notification to eliminate the failure

4. Quality requirements:

      The noise reduction project undertaken by our company must meet the function of product introduction. All materials are national standard products, and the parts are consistent with the product standard equipment.

5. Project period:

      According to the size of the project, the work day will be determined for completion from the date of construction.

6. Acceptance criteria:

      1 meter away from the factory boundary, 0.5 high, daytime noise is less than 65 minutes, and sudden noise does not exceed 15 minutes. The temperature at the control surface of the unit does not exceed 4-8 degrees Celsius of the outside temperature.
