GYF fire temperature exhaust axial fans Overview; 1, use: GYF fire temperature exhaust axial fans tested in accordance with GB50045 ~ 95 "fire protection design of tall buildings" and GB50067-97 "garage, repair garage, parking lot design fire protection "exhaust fan to buy a new energy-efficient exhaust fan the fire. The fan can be used as various buildings dedicated exhaust fan fire exhaust purposes, but also for high-rise buildings, general building, underground garage, culverts and other mines of smoke and ventilation, such as underground library usually used for ventilation ventilation, smoke with winds of revolution when needed. 2, Structure: leaf type with axial flow: There GYF-I (single speed) and GYF-SI (double speed); two kinds of fire exhaust fan. Leaf type with oblique flow: There GYF-II (single speed) and GYF-S2 (double speed) of two fire exhaust fan. If users have higher requirements on noise, you can make GYF-BX silencer exhaust fan the fire. Fans can also be made vertical exhaust fan mounted on the roof to do with fire smoke. GYF fire temperature exhaust axial fans consists of five main components: (1) the impeller (2) motor (3) circulating air impeller (4) guide vanes, the inner tube, guide holes (5) of the outer cylinder. 1. Commissioning number less than two, one to control power, one observes fan operation, abnormal phenomenon immediately stop inspection; First check the direction of rotation is correct; fan during each phase of the operation should be checked whether the current balance, current is exceed the rated current; if not normal, you should stop checking. After running for five minutes, the fan down to check whether there is abnormal phenomenon, confirmed that no anomalies start running again. 2. A two-speed fan test, it should start low, and check the direction of rotation is correct; it must be stationary fan speed after starting anew, to prevent the high-speed reverse rotation, causing the switch trips and motor damage. Fire exhaust fan set Location: Distance exhaust fan fire tunnel side walls should not be too close, so as not to affect the ventilation exhaust fan fire arrangement minimum distance from the wall of the tunnel 20 cm, rescue 'fixed' settings will tunnel into. Disaster different regions make full use of deviated and both ends of the tunnel exhaust fan fire rescue station designated as wind and smoke into the new channel, ventilation must be maintained at a positive pressure cross-channel ports to prevent flue gas flow channel. ventilation system from a secure tunnel to cross-channel air through the exhaust fan direction tunnel accident principle, suppress the flue gas into a cross-channel and tunnel accident did not occur to meet the evacuees facing fresh air into the tunnel cross passages and safety, while ensuring wait area needed fresh air. region according to different accident inside the tunnel using different disaster prevention ventilation. 'sentinel' Disaster ventilation program implementation point relief when the train, in the 'point' range of contact for all cross-channel set The fan can be reversed to obtain fresh air from within the security tunnel. exhaust fan quotes, Chen Yu-conditioned (certified), exhaust fan by Wu Cheng Chen-yu air-conditioning Limited.
