Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. No power ventilation system on the roof of the plant, can achieve very good ventilation effect. Because often due to the operation of machine tools to produce heat and smoke pollution within the plant, according to the "thermal expansion and contraction," the principle of hot air expands, so the number of molecules in a given volume of air is reduced, relative density of hot air cooler air will be small , that hot air lighter than cold air, so the indoor hot air to rise, cool air to fall, the indoor heat or smoke pollution will gather on the roof near the fire axial fan prices, so the indoor temperature high pressure. Then as long as the rotation of the turbine on the roof with no power fan, indoor heat or smoke pollution will be void by the blades to spin works out outdoor diversion method, when the heat is withdrawn without power ventilators interior will produce low pressure, The outdoor air is lower than the high pressure, the air flows into the room, filling the space heat is extracted, and then to adjust the temperature, to the decontamination of smoke effects, clean indoor air becomes cool.

Description No power ventilation is running Cause "buzzing" sound is now without power ventilation noise reasons sum up, mainly in the following six: one: no power roof ventilators poorly installed roof ventilator should be installed in suspension can not be crushed by the spring foot bolts. Two: No power roof ventilators installed in contact with the window frame is too tight, hence resulting sash resonance roof ventilator running. Three: No power roof ventilators eliminate vibration seat cushion or set screw too tight, lose eliminate vibration effects, the resulting sound vibrations at work. Four: seat screws loose, bad impeller assembly, excessive speed, shaft mounting screws loosening Workaround: roof ventilator fan base, shaft screw fastening. According to the technical requirements of reassembly, adjust the impeller clearance. Five: Wind Blade chassis collision (cover). Six: axial fan motor bearings bad price, axial fan base screws loose, fan shaft is not fixed tight top with a hood body blade gap is too small. t35 axial fan prices, Flextronics ventilators (certified), Hainan price axial fan ventilation equipment from Liaocheng Flextronics Limited.
