Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. Natural ventilation is based on the air thermodynamic principles, by indoor and outdoor thermal pressure, complemented by natural wind, in the case without the need for power-driven continuous indoor air from the outdoors, while the inflow of fresh outdoor air, thereby promoting and improving indoor temperature and humidity conditions. Since this is an energy-saving ventilation, so the "heating, ventilation and air conditioning design specifications" GB50019-2003 the provisions of Article 5.2.1: the elimination of building heat, ventilation design than wet, should give priority to the use of natural ventilation. Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. To fan the body intact, no leakage of high pressure axial fan site: local fan body to be in good condition, no leakage high pressure parts. You must elevate when local fan installed 0.3 meters above (with track surface counting) and securely mounted. At the same time it must be made by designated personnel responsible for the management, to ensure the normal operation. 7. Local Fan and pressed into starting device must be installed into the wind tunnel building ventilation skylights, return air from the roadway of not less than 10 m, wind tunnel where the whole supply pressure is greater than the local fan intake air volume and the installation Place the return air in the wind tunnel of not less than 0.25m / s. 8, should be made of antistatic, flame-retardant duct. Hairdryer hanging straight no dead corner, every ring will hang, discovery break promptly repaired or replaced. Hairdryer corner to set up elbow, can not bend Shui dead, specifications and standards of local fan and install spare local fan automatically switches to work cross-duct joints shall be specified in the operating procedures. 9, normal operation and standby local fan was stopped after a loss of power, when the power is restored, the local fans and spare local fan normal work shall start on its own, must be manually turned on local fan. 10, using the local fan sites for wind wind power lockout must be implemented to ensure the normal operation of the local fans when stopped or cut off after stopping the wind can stop the wind zone all non-intrinsically safe electrical equipment supply. Local fan fault working, switch to alternate work of local fan ventilation rectangular skylight, should stop within the scope of work of local fan ventilation roof ventilation skylights, troubleshooting; After troubleshooting, recovery to normal operation after local ventilation before return to work. 11, once every ten days methane ventilation skylights wind blocking test at least, every day should be local fan with a standby local fan once a working automatic switching test, shall not affect the local ventilation during the test, the test records to be archived for future reference. Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. Through axial fan power required means the specific conditions, plus the mechanical losses due in terms of the safety factor. To avoid motor overload burned, at start-up and commissioning of axial flow fan, must stop at no load conditions. As good condition, and gradually open the gate to reach the rule conditions so far during operation should strictly control the current, shall not exceed the motor rating. When the axial fan starts, when reaches 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 is not greater than 6.3mm / s . Such as found in axial fans have violent vibration, shock, rapid increase in bearing temperature anomalies, etc., required emergency stop. Plant ventilation skylights, ventilation silver sunroof, Flextronics ventilation provided by the Liaocheng Wei Chong ventilation equipment.
