Introduction to Silencing Engineering of Diesel Generators

Jun. 24, 2022

When the diesel generator runs at 1500rpm, a noise of 105 decibels will be generated at a distance of one meter from the unit. In order to prevent noise from being transmitted to the engine room, the noise reduction project should include the following links. Starlight power generation equipment will briefly introduce to you.

low noise generator

1. Muffler for the entrance and exit of the computer room

Each computer room has at least one entrance and exit door. From the point of view of noise reduction, the door of the computer room should not be set too much. Generally, one door and one small door should be set up, and the area should not exceed 3 square meters as much as possible. The structure is made of metal. The interior is equipped with high-strength sound insulation material, the exterior is metal iron plate, and the sound-absorbing door is closely matched with the wall and door frame up and down.

2. Muffler of the air intake system

When the diesel generator is working, there must be enough intake air to maintain normal operation. Generally, the intake system should be set directly opposite the fan exhaust port of the unit. According to our experience, the intake air adopts the forced air intake method. The muffler air trough is drawn into the machine room by the blower.

3. Muffler of exhaust system

Diesel generators use a water tank fan system for cooling, and the radiator of the water tank must be discharged out of the engine room. In order to prevent noise from being transmitted outside the engine room, an exhaust air muffler must be set for the exhaust system.

4. Noise reduction of the exhaust system outside the computer room

After the exhaust air of diesel generator is denoised by the exhaust muffler air groove, there is still a high noise outside the machine room. The outside of the trough is a brick wall structure, and the inside is a sound-absorbing board.

5. Exhaust muffler system

The exhaust gas emitted by diesel generators produces a certain amount of noise. We have added a muffler box to the exhaust gas emission system of the unit, and at the same time, the exhaust muffler pipes are wrapped with fire-resistant rock wool material, which can reduce the heat dissipation of the unit into the machine room. , and can reduce the working vibration of the unit, so as to achieve the purpose of attenuating noise.

Starlight Power has advanced testing equipment, modern production technology, professional manufacturing technology, perfect quality management system, and strong technical research and development capabilities. It can provide 3KW~2500KW various specifications of ordinary, automatic, four protection, automatic switching, low noise and mobile generator sets, high quality and low energy consumption to meet the diverse power needs of customers, and can also meet users with different voltages and different frequencies. It is required to create a parallel power supply system for multiple units. If you are interested in our product or any question on generator, welcome to send email to sales@dieselgeneratortech.com.
