Fan soundproof cover is an effective sound insulation measure to reduce the noise of high noise equipment. It seals off equipment with high noise, effectively blocking the external transmission of high noise equipment noise and reducing the impact of noise on the environment. Sometimes it can cause inconvenience for equipment maintenance, monitoring, pipeline layout, etc., and is not conducive to the heat dissipation of the enclosed device. Most require ventilation facilities to cool the air inside the hood.
Characteristics of Jingong fan soundproof cover: The soundproof cover produced by Jingong Machinery consists of soundproof components and supporting structures. According to different requirements, the soundproof enclosure wall is made of metal materials such as 1.5-2mm galvanized steel plate and aluminum plate. The soundproof cover adopts a modular design, which is convenient for transportation, suitable for on-site installation, and easy to maintain and repair. Perspective doors/windows, lighting equipment, ventilation and heat exchange systems, etc. can be installed according to different usage requirements, and different sizes can be customized according to requirements, with various exterior colors painted.
Application of Wanhao fan soundproof cover: Suitable for reducing the noise of various blowers, induced draft fans, generators, air compressors, transformers, crushers, ball mills, motors, water pumps, woodworking machinery, printing and other equipment. As a control room for high noise workshops, it can reduce the harm of noise to human health. At the same time, it is equipped with ventilation and cooling devices, heat dissipation devices, and inlet and outlet mufflers to ensure the normal operation of the equipment. Our company can independently complete the design, manufacturing, and installation of soundproof enclosures; There are successful engineering cases such as punch press soundproof covers, Roots blowers, and centrifugal blower soundproof covers.
The sound insulation cover effect of Wanhao fan: Depending on the form of the sound insulation cover, it can generally achieve a sound insulation of 10-30dB.
Fan noise control measures: In addition to considering the noise from the air outlet, the noise from the fan body and the solid sound transmission of vibration should also be given attention according to the on-site situation. Due to the loud noise emitted by the fan during operation, and the fan noise also increases with the increase of air volume and pressure. There are usually several methods to solve the problem of fan noise:
(1) The noise of the casing and motor can be solved by installing soundproof covers, placing the fan in an independent soundproof room, and conducting sound absorption and insulation treatment in the fan room.
(2) Install a muffler outside the exhaust port of the fan, with built-in noise reduction inserts, to continuously reduce noise through special construction. Muffler is an effective measure to reduce the radiation or transmission of noise along the inlet and outlet of aerodynamic equipment.
(3) Use soundproof louvers as much as possible for the exterior louvers on the ground floor.
(4) The fan suspension adopts damping spring suspension damper.
(5) Perform overall vibration isolation treatment on the fan foundation.
