Products; fire exhaust fan installed in the production of it can be directly connected to the wind pipe or wall-mounted exhaust fan buy, and it can be installed in the form of vertical or horizontal, so it saves a large extent covers area. In addition, it also can run more than 60 minutes continuously under high temperature 300 ℃ conditions, at a temperature of 100 ℃ continuous 20 hours / times without damaging the exhaust fan, it is widely used in high buildings, oven, underground garage, tunnels and other occasions. Exhaust fan fire a wide range: it can according to the different requirements of senior civil use of variable speed or multi-speed drive form, in order to achieve one machine (ie, when used through ventilation and fire high-temperature exhaust) purposes; leaf type divided axial flow (HTF-Ⅰ, Ⅱ) and mixed flow (HTF-Ⅲ, Ⅳ), so fans of the series has a wide range of performance parameters. Special attention is required when users require a higher noise, it can be made into a silencer-type fan. Fire temperature exhaust fan, can be used for various building fire smoke, but also for a variety of construction, civil air defense projects, underground railways, mines, tunnels and other smoke and exhaust. Other notes The fan is designed with special high-temperature motor cooling system. Main air duct medium temperature exhaust fan 280 ℃ principle, it can run more than 30 minutes continuously. ≤150 ℃ when long-term continuous operation. 1. Small size and lightweight light with the same amount of wind centrifugal fan less accounted for two-thirds of the space. Lighter than half. 2. Simple structure The fan consists of five main parts. The impeller motor ③ ① ② ④ circulating air cooling system guide vanes, inner tube ⑤ outer cylinder. Disassembly and easy maintenance. 3. Easy installation The fan is available upon request building construction crane with horizontal and vertical installation. The power of three-phase 380V, 50HZ1 when commissioning less than the number two exhaust fan Chen Yu, a controlled power supply, one fan running observe, abnormal phenomenon immediately stop inspection; First check the direction of rotation is correct; Fan process should Check the operating current of each phase is balanced, the current exceeds 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.
