[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - fan] fan noise detection and fan vibration detection: the main basis GB / T 2888-2008 "fan and blower noise measurement method", JB / T 8690 -1998 "Industrial Fan noise limits", JB / T 8689-1998 "fan vibration detection and restrictions", GB 9068-1988 "heating, ventilation and air-conditioning equipment - Determination of sound power - Engineering method", GB / "Determination of sound power levels of noise sources reflecting plane free field sound pressure - Engineering method" T 3767-1996. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product --HTF fire exhaust fan] installation process a comprehensive sample of fans familiar, familiar fan specifications, form of the impeller rotation direction and the direction of the air flow in and out, etc., Fans should be checked before installation whether the collision phenomenon impeller wind chassis, and conduct a comprehensive inspection of the components, the attachment is complete, whether the firm connection of the components, carefully check whether the blades due to shipping damage or deformation, otherwise it should be repaired before installation . 2, there should be a separate duct connecting the fan support import and export, plus the weight of the pipe is not allowed on the blower parts, turbine installation should pay attention to the horizontal position of the fan, the fan and the ground connection to the combination of surface and out of the wind pipe should be adjusted so that the natural fit exhaust air box, not be forced to join. 3. After installing the fan, hand or lever Stubbs impeller, check whether there is too tight or collision phenomena, whether or interfere with the rotation of objects pipeline wind chassis, htfc wind chassis no abnormal phenomenon, the only test run, the wind opportunity the exposed parts of the actuator should guard (user-supplied). Such as when the fan is not connected to the inlet pipe, also need to purchase protective nets or other safety devices (user-supplied). 4, the fan wiring must be accurate and reliable, the fan housing should be properly grounded, grounding must be reliable. Fan power supply must be complete and comply with the relevant requirements. Electrical wiring must have electrical wiring expertise.
