When the indoor or surrounding environment has strict requirements on the noise generated by the equipment, Dongguan Ruitian Electromechanical "target=_blank> electromechanical suggestion, in addition to the vibration and noise reduction treatment of the Reitz centrifugal fan, should also do noise reduction, sound insulation deal with.
Mosquito Net For Bed and Tent net
The Reitz fan is mostly treated with an acoustic enclosure, and the Reitz fan enclosure is made of various shapes according to the type and size of the fan. It is made up of a number of standard or non-standard sound insulation panels, or it can be made into a single cover. The cover body leaves the fan inlet and outlet and the inspection door, and all other parts are closed. In order to eliminate the heat dissipated during the operation of the motor, an exhaust pipe is installed on the top of the cover.
The sound insulation cover can be made of steel and flame retardant FRP.
The structure of the steel sound insulation board is mainly the method of adopting the internal suction outer partition. The principle of action is that the vibration wave generated by the operation of the Reitz fan and the sound wave generated by the high-speed movement of the air flow are gradually passed by the perforated plate and the glass cloth to the ultra-fine glass wool board. The tiny pores are absorbed, and the galvanized outer panel can prevent the sound waves that are not completely absorbed from coming out of the cover and protecting the seal.
The glass fiber reinforced acoustic enclosure is made of a non-metallic multilayer composite structure. The soft and hard sound-absorbing sound insulation materials are alternately arranged, and the sound waves can be applied to different materials to generate reflection and absorption to achieve sound insulation. effect.
