Fire exhaust fan, as a dual-purpose machine ventilation equipment, plant and equipment by the residents and the shop's favorite, today will take you to a detailed understanding of the important role under fire exhaust fan in the mechanical ventilation. With the initial fire exhaust fan there may be windows, walls condensation exhaust fan principle, even slight condensation surface grain surface, as long as the fan is stopped, open the windows, turn on axial fan, exhaust fan turning grain surface specifications necessary, The humid air inside the warehouse outside the warehouse can be excluded. Fire temperature exhaust fan installation process: 1, fully conversant with the sample fan, familiar fan specifications, form, impeller rotation direction and the direction of airflow in and out, etc., before the wind turbine installation should be checked whether the collision phenomenon impeller exhaust fan picture and to conduct a comprehensive inspection of the components, the attachment is complete, whether the firm connection of the components, carefully check whether the blades before installation due to shipping damage or deformation, or should be repaired. 2, import and export of the fan duct connection should be a separate support, 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 exhaust fan, the fan and the foundation of the joint surface and the wind connecting pipeline should be adjusted so that the natural fit, not be forced to join. 3, after the wind turbine installation, by hand or lever Stubbs impeller, check if there are too tight or collision, the availability interfere with the rotation of the article, no abnormal phenomenon, the only test run, the exposed parts of the wind opportunity gearing should protective cover (user-supplied). Such as the fan inlet pipe is not connected, but also need to purchase fencing or other safety devices (user-supplied). 4, the fan wiring must be correct and reliable, the fan housing should be properly grounded, grounding must be reliable. Fan power supply must be complete and meet the relevant requirements. Electrical wiring Electrical wiring must have professional knowledge.
