Fire smoke exhaust fan is mainly used for industrial and civil construction and civil air defense projects, usually also be used for indoor ventilation. Motor with high temperature and a cooling air circulation system, long-term operation at 100 ℃ medium gas can be smoothly transported 280 ℃ smoke up to 40 minutes or more. Horizontal, vertical, cabinet, three types are available. When dual exhaust ventilation, optional two-speed motor, low speed ventilation, high speed exhaust. Francis fan using advanced three-dimensional flow model design, but also has a high pressure axial fans and centrifugal fans high flow characteristics Hefei positive pressure blower, small size, high efficiency, easy installation, saving space for a variety of situations in the pipeline pressure ventilation. Oblique flow fan glass steel and steel are two, both centrifugal fans and axial fans high pressure coefficient flow coefficient characteristics of high efficient wide area, low energy efficiency, noise, can be directly connected in series in the pipeline ventilation, easy installation, saving space, no fan room paiyanfengjpaiyanfeng price Anhui axial fans, axial fan is the same direction with the axis of the air flow blades (ie wind direction and parallel to the axis), such as electric fans, air conditioning unit is an axial flow fan mode run fan. Axial fans called local ventilator positive pressure blower, industrial and mining enterprises commonly used as a fan, it is different from the general fan, its motor and blades in a cylinder, the shape is a cylindrical shape, for topical easy ventilation, installation, ventilation effect is obvious, safe, hair dryer can be connected to the designated lookout area. Axial fans 2 constitute axial fan is mainly composed of 1- hub; 2 - blade; 3- axis; 4- shell; 5- concentrator; a 6- streamline body; 7- rectifiers; 8- diffuser. As well as inlet and an impeller. Inlet by a set of wind and streamline body composition, the hub of the impeller blades 1 and 2 components. Impeller and shaft 3 are fixed together to form the fan rotor, the rotor is supported on bearings. When the motor-driven fan impeller rotates, there is the gas flows through each blade. [1] 3 works axial fan blade works with an airplane wing is similar. However, the role of which is to lift up on the wing and supports the weight of the aircraft, while the axial fan is fixed to the position and movement of air. Gas flow from the collector into the axial fan, the leader after obtaining pre-swirl leaf blower roof pressure to obtain energy in the rotor blades of the impeller, and then after the vanes, a portion of the deflection of the air flow kinetic energy into static pressure energy, the last gas flows through the diffusion tube, a portion of axial flow of kinetic energy into static pressure can enter into the pipe [2]. The company's main products are aluminum foil phenolic compound duct, color steel composite duct, extruded aluminum foil composite duct, GF-Ⅱ Goldwind composite duct, MG non-combustible inorganic glass fiber and magnesium duct, BWG water resistant non-combustible inorganic glass steel duct, GRC fiberglass duct, fan, muffler, fire dampers, aluminum outlet. Also sells fire-resistant partitions, fire package, blocking materials, and undertake water, electricity, heating, air defense and other installation business, the company pioneered the delivery of quality system certification of positive pressure blower manufacturers through the ISO, it is widely used throughout the province. To better serve the market, the company set up and installation company, to carry out integrity, credibility and achieved broad market.
