Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. Roof ventilators at room temperature will be some high temperature conditions runtime, but are within the normal range, electric ventilators, which is due to friction between the parts of the machine itself, lead to high body temperature generates heat, but Not all over-temperature condition is normal. Fans device body temperature than normal, the following main reasons: The first: the motor bearing damage, with a small gap, does not meet the requirements. The second: The system resistance is too large or fan motor overload caused by an irrational option, because the pipe network resistance coefficient is too large or pipe coefficient Valve does not open; third: power supply pressure is low; fourth: Motor off phase movement or wiring error; fan body is actually too high a more serious problem, natural ventilation, especially for axial fans, roof fan these have important mechanical equipment, there are a little unusual place, it will affect to the normal operation of the machine, people should pay attention to. Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. Adjust the axial fan air flow method, air flow axial fan shifting adjustment: by changing the axial fan speed to achieve axial fan characteristic curve of change, thereby changing the amount of ventilation is an effective method of saving axial fan is running. 2, air flow axial fan at constant speed adjustment: for axial fan. By increasing the blade angle can be increased pressure, can also be adjusted by varying the amount of ventilation progression or blade work round number. However, these adjustments are generally required to be shut down when the fan is only suitable for a longer phase adjustment amount of wind, unable to achieve a smooth adjustment of ventilation and follow the actual ventilation requirements. Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. No power ventilation air using the principle of natural convection, becomes in any direction parallel to the flow rate, and the vertical air flow conversion. With the use of the chimney effect itself, ventilation, buildings and equipment to achieve an internal and external ventilation equipment. No power ventilation applications: large factories, warehouses, stadiums, pet farm functional areas, high-rise buildings, residential and other ventilation. Roof ventilation _ Flextronics ventilators (certified) _ Liaocheng ventilation is provided by Flextronics ventilation equipment.
