HTFC (DT) series of fire ventilation (dual) low noise cabinet centrifugal fan use, maintenance 1, check A fan installation before use, to understand the specifications of the fan, form, inlet and outlet position B, the blades should be carefully checked before installation and install the appropriate size, with motor power requirements C, exhaust port and exhaust fan should be set up interlock device, when any one of the exhaust port open, exhaust fan that is able to automatically start. D, before fans start, first check whether the prejudice within the rotating fan and piping items, check the electrical wiring is intact E, after installation, periodic inspection of the components fan, check the bearing lubricant is sufficient to ensure that the fans can start at any time, Zhejiang wind chassis, normal operation. F, impeller rotation direction must be marked with duct Jane consistent head. 2. Fan common fault analysis A, vibration. Many causes can be checked from the following aspects; a, because storage enclosure deformation of the impeller rotation grazing. At this will sound unusual and severe vibration Anhui wind chassis, because the storage and transportation process or impeller fan casing parts deformed. b, fan foot bolts not tightened. c, because the impeller compression deformation, loose loose coupling, bearing damage the impeller balance destroyed. B, motor heat. It may be caused by one of the following reasons. a, motor bearing damage. b, geometric tolerances of the motor shaft and fan shrouds installed does not meet the technical requirements. c, the power supply voltage is too low. 3. Maintenance fans the best regular maintenance at least once a year, check the bearing wind chassis models, the internal fan to eliminate dust, dirt. HTFC (DT) series of fire ventilation (dual) a low noise cabinet centrifugal fan, HTFC (DT) series of fire ventilation (dual) low noise cabinet centrifugal fan Overview tank centrifugal HTFC series of fire ventilation (dual) low noise Fans are Shanghai Jiaotong University and the success of our plant jointly developed a high-efficiency, low-noise centrifugal fan wind chassis, with a high temperature, excellent performance, the new structure is compact, small vibration, light weight, and easy to install and use.
