Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. An axial fan roof ventilation equipment for industrial workshop roof ventilation axial fans is based on the principles of the natural environment caused by the flow of partial pressure difference and air flow generated by the gas, the roof so no power-driven axial fan, can effectively cost and energy savings. No wind when the outdoor roof exhaust fan, you can rely on a stable temperature difference between indoor and outdoor air exchange flow is achieved. When a large outdoor natural wind when the wind speed exhaust fan factory roof, the roof axial fans will be able to rely on outside pressure to ensure the effective air exchange. Under the same ventilation area ventilation effect depends on the following factors: 1, the size of indoor and outdoor temperature. Promote the flow of gas pressure to boost air flow. 2, outside the room size natural wind. Indoor and outdoor pressure difference caused by large, allowing air to flow. 3, the impact of high and low temperatures also contributed to the air flow and exchange of reasons. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Through axial fan power required to offer means exhaust fan in the roof of a specific condition, coupled with proper mechanical losses in terms of the safety factor. To avoid electrical overload burned when axial fans start up and commissioning, must stop at no load conditions. If in good condition, and gradually open the gate fiberglass roof exhaust fan, arriving until the rule conditions, during operation, should strictly control the current, shall not exceed the motor rating. When the axial fan starts, reaching the normal speed, during operation, always check whether the normal bearing temperature, bearing temperature must not exceed the ambient temperature around 40 ℃, the root mean square value of vibration velocity bearing parts must not be greater than 6.3mm / s . When axial fans have found violent vibration, shock, rapid increase in bearing temperature anomalies, etc., required emergency stop.
