current location: DN High efficiency silencer

DN High efficiency silencer

At present, the air conditioning and ventilation system of ships mostly adopts centralized air supply system to realize the air environment control in the cabin. The main noise sources are as follows: one is the noise of (combined) air conditioners and ventilators; The second is the regenerative noise of air flow in the air duct and equipment, including the noise generated by the air duct and the tuyere. Therefore, noise control needs to start from two aspects: on the one hand, optimize the system design, reduce the noise from the sound source; On the other hand

Adopting measures of sound absorption and noise reduction to control the noise propagation can attenuate the noise to a lower value to a certain extent. In the air conditioning and ventilation system, air flow needs to pass through the air outlet. In this case, vibration isolation and noise reduction schemes can not meet the needs in some positions. At this time, we generally install mufflers on the ventilation pipe to reduce noise. According to GB/T 25516-2010 standard, zhaisheng air conditioner is specially developed for all kinds of ventilation systems with high efficiency muffler, which has the characteristics of good noise cancellation effect, small air resistance loss and easy installation. Widely used in various equipment rooms, garages, ships and offshore platforms and other places.

Model Description:

DN: silencer

"1600" inside diameter size

Composition: the muffler is composed of muffler shell and muffler unit, and the muffler unit channel is set in the middle. The muffler unit channel is made of muffler hole plate, superfine glass fiber cotton and glass fiber hole cloth.

Product features:

DN series Marine muffler is a muffler device which attenuates or prevents sound transmission and allows air to pass through. With the help of sound absorbing material or sound absorbing structure, the noise transmitted along the pipeline attenuates with the increase of distance, and the sound energy is absorbed and converted into heat energy to achieve the purpose of muffling and reduce the airflow noise in machinery.

DN series muffler for ventilation pipe muffler, for Yin anti sound flow type; It can absorb and reduce the noise of high and middle frequency, suitable for each cabin.

Product advantages:

Our muffler can be made into round type, square type, and fan matching use, good ventilation flow, low resistance, good muffler effect, vertical installation can also be horizontal installation. The muffler unit has ideal muffler effect and good aerodynamic characteristics in a wide frequency band. The special design of diversion and orifice plate makes the resistance loss smaller.



Basic parameters:

● DN300-600 noise reduction: 4-6 dB(A)

● Dn700-1000 noise reduction: 6-8 dB(A)

● DN1200-1600 noise reduction: 8-10 dB(A)

● The shell is made of ordinary steel plate and can also be made of stainless steel and other materials according to user requirements;

● Silencer plate common steel plate stamping, rolling, but also according to user requirements, the use of stainless steel and other materials;

● Silencing cotton using superfine glass fiber cotton

● Glass fiber cloth is covered on muffled cotton to fix muffled cotton and prevent its scattering.


Application:

Widely used in various types of passenger ships, cargo ships, naval vessels and offshore oil platforms and other places.
