[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - Fan] trends: forecasting general ventilation fan from the main areas of demand structure (typically for small and medium centrifugal and axial flow fan) the most widely used, demand maximum amount, the manufacturer is also up. Overall speaking, this kind of product oversupply. Special purpose fans (including anti-corrosion fan, heat fan, wear fan, exhaust fan fire, etc.) demand, while not great, but the special operating environment, require separate treatment, because the main material requirements more special. Roots blower is the most important feature within the allowable range when the pressure regulator, the flow rate has changed little centrifugal fan, a wide range of selection pressure, having forced gas transmission characteristics, the main drawback is noisy. [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 out of the exhaust, etc. before the smoke blower fan installation should be checked whether the collision phenomenon impeller fan, 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, or should be repaired rear can be installed. 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 unit heaters, fan installation should pay attention to the horizontal position of the fan, the fan and the foundation of the joint surface and the wind pipe The connection should be adjusted to make it a natural fit, 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 items, no abnormal phenomenon, the only test run, the exposed parts of the wind opportunity gearing should protective cover (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.
