Fire temperature exhaust fan 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 ℃, it can be 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. Three-phase 380V power supply exhaust fan specifications, 50HZ 1. centrifugal fan wind chassis, motor power is the desired conditions to be determined, together with proper mechanical loss reserves, it is not a fully open when the outlet power required, such as the fan outlet duct is not connected or add external resistance and empty running, the motor burned danger, for safety reasons, the valve should be added at the fan outlet or inlet pipe, starting the fan Close, will slowly open the valve operation, is reached a predetermined condition, and pay attention to fan current exceeds a predetermined value. 2. The fan allows full pressure start or step-down start, but it should be noted that the current full voltage starting time of 5 to 7 times the rated current wucheng exhaust fan, voltage starting torque is proportional to the square of the voltage, when the grid capacity insufficient, should step-down start. (When the power is greater than 11KW exhaust fan use, should be adopted step-down start). Use; 1.MHL3-2A, MPYH-14A (MHTFL-14A) Francis two-speed high-temperature exhaust fan for tunnels, underground garage, metallurgy and other high-temperature exhaust, in the case of fire, can quickly exhaust cooling assistance firefighters into the disaster area fire, fire safety is an essential facility. 2, the type of gas transportation: air and other non-natural, harmless, non-corrosive gases for just, in special circumstances, the choice of explosion-proof Francis fan. 3, impurity gases inside: adhesive materials are allowed within the gas contained in the dust and hard particles is not greater than 150mg / m3. 4, the temperature of the gas: MHL3-2A, MPYH-14A (MHTFL exhaust fan hydraulic _ Chenyu air conditioning (certified) _ exhaust fan by Wu Cheng Chen-yu air-conditioning Co. wucheng Chenyu Air Conditioning Equipment Co., Ltd .. (www.wccykt.com) is an industry leader in Shandong Dezhou, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
