Roof ventilation performance mainly reflected? (3) step-up roof ventilation duct to collect roof air ventilators, without power fan assembly diagram, the wind pushed the amount of non-powered exhaust fan to form a bottom discharge hot air upward actuated position ; top (4) roof ventilators wind in any direction, the ventilator is bound to a suction outlet ventilation to improve the speed bump. Adjust the motor, hydraulic coupling, when the coupling between the roof axial fans, using the following two methods are inappropriate alignment: 1, by coupling halves are not in contact with a dial indicator fixed on a stationary coupling halves, the roof axial fans allow probe to measure the other rotary coupling halves radial and axial runout. 2, to help assist with a feeler flat block radial and axial runout. 3, the roof to adjust the axial flow fan with horn dimensions, the horn is applied between the bottom plate and foundation horn, Liaocheng without power fan, and each bolt is tightened, the bolt force to ensure a substantially uniform. 4, the roof axial fans use pump lubrication, running bearings are generally not lose oil, so when the slinger damage, Taiyuan without power fan, too lazy to fill because of the inconvenience of installation and equipment. 5, fan slinger role in that encounter unexpected roof axial flow gas station outages or short fault and not the normal supply, the oil ring from the bearing housing oil pool will lift oil to supply certain bearing The oil, to ensure its continued rotation without damage, so must not be missing. Taiyuan without power fan | large unpowered fans | ventilators Flextronics (high merchant) provided by the Liaocheng Wei Chong ventilation equipment. Liaocheng Flextronics ventilation equipment (www.lcwctf.com) (www.lcwctf.com) provide customers with "no power ventilation" and other business, the company has "Flextronics" brands. Focus on the fan, ventilation equipment and other industries, have higher visibility in Liaocheng. Welcomes inquiries, contact: Du Jingli.
