I. Product Overview

 SCF-type fire ventilation (dual) axial fans for high-rise buildings and underground fire exhaust systems and supply and exhaust ventilation systems. Has high efficiency, small installation space, light weight, easy to install features, is the latest development of products, but also high-rise buildings and underground ventilation equipment replacement products.

 II. Features

 1, Multifunction: Civil ventilation equipment industry is growing, also contributed to the matching motor manufacturers design capabilities and manufacturing levels progress. Quality with high temperature electrical fans supporting the continuous improvement in the company after the motor manufacturers with continuous testing and improvement of the motor insulation class F necessary modifications, in the case of no special cooling system, fully capable at 300 ? safe operation under high temperature over 90 minutes, the exhaust fan by the National Fire Equipment supervision and Inspection Center qualified. When a fan for ventilation change places, the use of ordinary motor, when the fan is used to fire exhaust system, using the modified class F insulation of the motor can be. According to different uses with different motors, to achieve multi-functional purpose.

 2, multi-parameter: This series of fan impeller diameters from 250mm to 1600mm, a total of 20 kinds of fan model, each fan with three different wheel design performance ratio, the ratio of each wheel is equipped with two different impeller speed motor, so a total of 120 kinds of different specifications of the fan. Air volume ranging from 705m3 / h to 167040m3 / h, pressure range from 40Pa to 1147Pa. Each specification fan at least five optional efficient operating point can achieve the goal of multi-parameter, which greatly facilitate the users to choose.

 3, the installation space is small: when the system fan exhaust fan when the alternative, because no special cooling systems, fans shorter length can be reduced about 30%. Users can reduce the investment in the turbine room. Users can easily handling and installation, will help improve the overall progress of the project.

 Three. Product Process

 1. Impeller: Baosteel produced blades made from high quality Q235 steel, metal cutting, hydraulic molding. Wheel Baosteel produced from high quality Q235 steel, hydraulic machine stretch forming. Leaves by special welding equipment welding protection of carbon dioxide gas. And by the significant number of hard-bearing balancing machine calibration, balancing accuracy G4.6 level and above.

 2, Hair Dryers: Baosteel produced from high quality steel with Q235 cutting shears, with three core Bending rounded, carbon dioxide gas welding. Spinning flow forming machine, beading machine spinning and then the two arc-shaped ribs on the barrel. Guarantee duct has sufficient strength, stiffness, elegant appearance.

 3, the inner tube: inner tube made of high quality steel Q235 Baosteel produced by cutting shears, with three core Coil rounded, beading machine, including two arc-shaped spinning barrel ribs. To ensure that the inner tube has sufficient strength and rigidity. Wicket with plasma cutting cutting, hydraulic molding machines, with carbon dioxide protection welding.

 4. Assembly: After the fan assembly, X, Y, Z axis vibration velocity is less than 5.6mm / s.

 5, high temperature performance: Fan can run 60 minutes at 300 ? above normal high temperature conditions, in full compliance with the National Fire Code
