Low noise centrifugal fan cabinet is to meet the growing current air conditioning, purification of industrial and environmental noise requirements in the digestion and absorption of foreign advanced technology premise, using the principle of aerodynamics and aeroacoustics combining redesign successful development of new products. Wind volume, total pressure, low noise, small vibration, etc. exhaust chassis, in line with the requirements of environmental protection and labor protection. Low noise centrifugal fan cabinet is to meet the growing current air conditioning, purification of industrial and environmental noise requirements of wind chassis, in the digestion and absorption of foreign advanced technology premise, using the principle of aerodynamics and aeroacoustics combining redesign of the successful development of new products. Wind volume, total pressure, low noise, vibration and other characteristics, in line with the environment ... 1. Fans should be possible to aerodromes or arranged on the platform, in order to maintain and repair; when equipped with centrifugal fan motor pressurized air box when power is less than or equal to 75kW, do not just start with the installation of the valve. When the result of the carriage of high temperature gas or air and the choice of boiler centrifugal fan, should be set up to start with the valve, causing the motor to prevent overload cold running. 2. Fan mounting pedestal (base) should have sufficient strength, stability and durability, vibration pedestal shall meet the following requirements: a natural frequency) base unit shall not exceed 1/3 of the motor and fan speed; 2 ) difference vibration velocity and vibration velocity fan stationary fan operation must be greater than the time of more than 3 times. The connection between the import and export with duct 3. fan, flexible joints should be located. Inlet duct, the duct, and other devices should be supported independently by the foundation or support other components of the building firm, should not bear the weight of other chassis parts are. 4. When the fan is mounted on the building elements, isolation measures should be taken to wind chassis htfc, wind chassis, rich ventilation equipment from Dezhou Plumper ventilation plant. Dezhou Plumper ventilation plant (0) strong, credible, in Dezhou fan, ventilation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Plumper ventilation equipment into the brilliant and you work for a better future!
