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, exhaust fan specifications, 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. HTF series exhaust fan fire for high-rise buildings, underground buildings and tunnels, drying room and other high-temperature exhaust or ventilation. Continuous operation at 280 ℃ under the high temperature for 30 minutes or more, the medium temperature at 100 ℃ continuous operation 20 hours / times without damage, fire is the ideal necessary facilities. 1, the performance of the fan performance table lists the properties in the most efficient range, according to the performance of the air volume is divided into five working points, according to prevail in the selection of the performance table. Qualified fan factory is rated flow, total pressure error does not exceed ± 5%, the performance of the selection list is performance under standard conditions, regardless of the technical documentation or performance are subject to the requirements of the standard state orders; 2, the fan installation can be divided into horizontal and roof type, Pu'er exhaust fan, air volume, total pressure, dimensions and other properties have special requirements; install an exhaust fan in front, before the wind turbine installation should be carefully examined whether the fan intact, each fastener bolts are loose or fall off, whether the collision impeller hood. carefully check fan or blinds during transport without deformation damage. 2, the installation environment select the outlet, exhaust fan model, attention should not have too much of the opposite outlet obstructions within 2.5 -3M. When the exhaust fan installation 1, the installation smoothly: the wind turbine installation should pay attention to the horizontal position of the fan, the fan and adjust the level of a solid ground plane after installing the motor can not have tilt. 2, the fan should be installed so that the motor is in position adjustment bolts easy to operate. When adjusting belt tension for ease of use. 3. When installing the fan bracket, exhaust fan price, be sure to let stand firm and level ground plane, re-install the angle iron reinforcement if necessary next fan. 4, the fan after installation, to check their tightness around. If the space available solar panels or glass glue for sealing. Exhaust fan quotes, Chen Yu-conditioned (certified), Pu'er exhaust fan by Wu Cheng Chen-yu air-conditioning Limited.
