Performance: A: It has excellent sound insulation performance, which can reduce the noise of the unit within the specified level.

To this end, an important factor is fully considered in the design of the sound-proof box, one is that the box should have the necessary ventilation and heat dissipation conditions to ensure the normal operation of the unit, and the other is that the sound insulation and sound absorption performance of the sound-proof box should be as high as possible. In this way, the key to the design of the sound protection box is mainly how to determine the area of the air inlet and exhaust outlets. Let it strike a balance between the two.

According to the experience in the design and development process, there are:

The effective ventilation area of the exhaust should be 125%-130% of the effective ventilation area of the radiator.

The effective ventilation area of the inlet air should be 105%-110% of the effective area of the exhaust air.

B: The unique design of the air inlet groove of the soundproof box can effectively let the cold air pass through the air inlet groove of the soundproof box, and the heat generated by the unit will be discharged out of the unit through the exhaust fan according to the principle of convective heat transfer.

Whether it is a domestic silent diesel generator set or a silent imported diesel generator set, there are many products in the market. However, there are many things to pay attention to in how to choose a ***** silent diesel generator set.

1. First of all, we must choose a regular diesel generator set direct sales manufacturer.

2. Consider the purpose of the unit. Because the silent diesel generator set can be used in 3 situations, such as common, standby and emergency. Therefore, the requirements for silent diesel generator sets are different for different purposes.

3. Load capacity. The load capacity and load change range should be selected according to different uses, and the single capacity of the silent diesel generator set and the standby silent diesel generator set capacity should be determined.

4. The environmental conditions of the unit (mainly referring to the altitude and climatic conditions) 4. The selection of silent diesel generators.

5. Selection of generator and excitation mode.

6. The selection of the automation function of the silent diesel generator.

The purchase of silent generators should first pay attention to the selection of unit manufacturers, and choose the OME factory of well-known diesel engine manufacturers to ensure the quality and after-sales service of the unit.

Then pay attention to the purpose of the silent generator. Because the diesel generator set can be used in 3 situations, such as common, standby and emergency. Therefore, the requirements for diesel generator sets for different purposes are different.

Load capacity. The load capacity and the load change range should be selected according to different uses, and the single capacity of the diesel generator set and the standby diesel generator set capacity should be determined. It is also necessary to pay attention to the choice of unit brand and configuration, and be willing to communicate with the manufacturer.

There will be some consumption when the generator set is running, and the exhaust gas consumed by these consumption should be directly discharged, so the speed of the fan will be significantly enhanced when the exhaust gas is discharged, which will cause the appearance of exhaust sound. When the generator is running, it will produce different noises with the process of operation, which is the mechanical sound, which is generated by general generators. There is also the noise of the cooling fan, which is a relatively common sound.

There will be noise when it is discharged, and it will also be noise when it is intake. Therefore, if it is used in urban areas, it requires that the silent diesel generator set is carefully designed by introducing foreign low-noise generator and engine technology; The design concept is advanced and the variety is complete. In addition to the ability of ordinary diesel generator sets, the product also has the following characteristics:

The noise of the unit is low, the overall mechanism is compact, and the space occupied is small; The box is all detachable structure, the box is made of steel plate splicing, the surface is coated with high-performance anti-rust paint, and it has the functions of noise reduction and rain protection; The inside of the box adopts a multi-layer barrier impedance mismatch silocation structure and a large impedance silencer built into the stove cavity.
