Products; 1.HTF type fire temperature exhaust axial fans, the basic form of an axial flow type structure, with high temperature motor, arranged a special motor cooling system, products by the National Fire Equipment Quality Supervision and Inspection Center GA211-1999 "fire exhaust fan high temperature test method" high-temperature test at medium temperature conditions of high temperature 300 ℃ continuous operation more than 60 minutes at a temperature of 100 ℃ continuous operation 20 hours / time is not damaged, can be dual exhaust ventilation. 1.2 Categories by Mounting points: horizontal and Roof (W type). Press the air flow pressure point: there is pressure type Ⅰ and Ⅱ (double speed); medium-pressure (mixed flow impeller) has Ⅲ, Ⅳ type (double speed); there is low pressure type D1, D2 type. Press Speed ??points: single-speed, two-speed, variable frequency (by frequency conversion motor with variable frequency controller, inverter implementation, in order to adapt to different conditions, it is recommended to adjust the frequency locked in 25Hz ~ 50Hz). 1.3. In order to meet the requirements of different places noise exhaust fan, the fan can be equipped with different lengths muffler, it can be made into a sheathed (housing silencer). 2, HTF-type fire temperature exhaust axial fans working conditions Operating temperature: -20 ℃ ~ + 60 ℃ (continuous operation); temperature: 100 ℃ (continuous operation 20 hours), 300 ℃ (continuous operation 60 minutes ); temperature: <90%; medium conditions: air (dust content of no more than 100mg / m3); Power supply: three-phase, 380V / 50Hz; 3, HTF-type fire temperature exhaust fan axial fans can be widely used application rise construction, oven, underground garage, tunnels and other places exhaust ventilation. 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 exhaust fan Wu Cheng, in the case of fire, quickly exhaust cooling, fire into the disaster area to assist firefighters, 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 principle exhaust fan, Francis fan explosion-proof choice. 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 range; (1): the fan connecting pipeline and installation of air conditioning inside, noise is less than 70dB (2): Alternative low centrifugal fan 2000pa less, can Widely used in industrial, civil ventilation and dust removal. MHL3-2A, MPYH-14A (MHTFL-14A) Francis two-speed high-temperature exhaust fan only has HL-3-2A Ventilator function, but also the environment around 280 ℃ 0.5 hours in normal operation temperature exhaust fan buy, both for ventilation, it can play a dual role in high-temperature exhaust, applicable to underground tunnels, underground shopping malls, underground warehouses, and other fire-fighting facilities, by design institutes and users selection. exhaust fan model, Chen Yu-conditioned (certified), exhaust fan by Wu Cheng Chen-yu air-conditioning Limited. wucheng Chenyu Air Conditioning Equipment Co., Ltd. (www.wccykt.com) Shandong Dezhou, fans, leaders ventilation equipment, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
