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 of 280 ℃ when the exhaust fan uses more than 30 minutes of continuous operation. ≤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. Power three-phase 380V, 50HZ install and use: 1) can be vertical, horizontal and hanger installation. Fan base must be flat natural combination exhaust fan base price, and not to beat coupling force base, the weight of the pipeline must not be applied to the turbine components. 2) should be carefully checked before installation whether the impeller and the casing due to transport damage and deformation, if any, should be repaired before installation. 3) Check for loose bolts, electrical insulation is good, whether the goods hinder the rotation within the fan duct. 4) After you install the fan to make a trial run, abnormal rub, touch and vibration to be excluded immediately. Performance exhaust fan; fire exhaust fan, said during use, not only to make the appropriate use and maintenance work, and to its performance fully displayed, and improve the efficiency of the fan, so as to increase its scope of application, get the majority of user acceptance. So we should make energy-efficient exhaust fan fire effect on how full performance of it, today as we detail below: For some relationship between the different flows, we adjust the way is also divided into several different approaches that adjust the way little impact on energy savings wucheng exhaust fan, even not only energy saving, but because of presence of a regulatory apparatus more power consumption. Variable-speed control curve closer to the ideal curve. So exhaust fan, variable-speed control mode is superior, especially the use of variable frequency motor speed control of energy-saving program is the best, but the need for additional frequency devices.
