Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Adjustable axial fan air flow method, the amount of wind speed axial fans during adjustment: by changing the axial fan speed to achieve change FRP axial fan characteristic curve of the fan without power, thereby changing the amount of ventilation, energy-saving operation is axial fan effective way. 2, constant speed axial fan air flow regulation: for axial fan. By increasing the blade angles can be increased pressure, can also be adjusted by varying the amount of ventilation series or number of pieces of work impeller wheel. However, these adjustments are generally required to be carried out in the fan down, only for a longer phase of adjusting the amount of wind, unable to achieve a smooth adjustment of ventilation and follow the actual amount of ventilation required. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. The role of mechanical ventilation axial fans in the grain temperature due to the temperature difference between the larger and the first time to choose the ventilation during the day without power turbine manufacturers to reduce the gap between food mild temperatures, reduce condensation occurs. After ventilation as much as possible at night, because this is a cool airy main evening relatively high atmospheric humidity, low temperature, so that reduces moisture loss, but also take advantage of the low temperature at night, improved cooling effect . When retarder ventilation axial fans, due to the small amount of wind power axial fan without fan, in addition to food is a poor conductor of heat, ventilation prone to individual parts of the initial slow airy, with airy proceed gradually warm whole grain warehouse balance. Slow food carried ventilation must be vibration sieve cleaning, and into the food must be promptly cleaned compartment automatic grading caused impurity region without power roof fan manufacturers, could easily lead to uneven local exhaust ventilation. Advantages to conduct retarder axial fan ventilation: cooling effect is good; low energy consumption, is particularly important in promoting energy today; ventilation and easy to grasp the opportunity, less prone to condensation; not alone with fans, convenient and flexible. Disadvantages: Due to the small amount of wind, a long time ventilation; ineffective precipitation, high moisture grain should be ventilated with axial fans.
