Fire Suppression High-Temperature Exhaust Fan Overview
1. Application: The GYF fire-fighting high-temperature exhaust axial fan meets the GB50045-95 "Code for Fire Prevention Design of Civil High-Rise Buildings" and GB50067-97 "Code for Fire Prevention Design of Parking Garages, Repair Garages, and Parking Areas," and is a new type of energy-saving fire-fighting exhaust fan. It can be used for fire and smoke exhaust in various buildings, as well as for exhaust and ventilation in high-rise buildings, general buildings, underground parking garages, mine tunnels, etc. For instance, the underground storage area is used for ventilation and air exchange during normal operation, and can switch to high airflow smoke exhaust when needed.
2. Structural Forms: Axial flow blade design: includes GYF-I (single-speed) and GYF-SI (double-speed); two types of fire smoke exhaust fans.
The blade design is of oblique flow type: featuring two fire and smoke exhaust fans, the GYF-II (single-speed) and GYF-S2 (dual-speed).
If the user has high noise requirements, a GYF-BX silencing fire smoke exhaust fan can be produced. The fan can also be made in a vertical design, installed on the roof for fire smoke exhaust purposes.
The GYF fire-resistant high-temperature exhaust axial flow fan consists of five main components: (1) impeller (2) motor (3) internal recirculation impeller (4) guide vanes, inner tube, and flow tube holes (5) outer casing.
3. Installation and Usage:
1) The fan can be installed in vertical, horizontal, or suspended mounting positions. The fan base must naturally fit with the foundation surface without forceful pounding to secure the base. The weight of the piping should not be added to any components of the fan.
2) Before installation, carefully inspect the impeller and housing for any damage or deformation due to transportation. If any, repair them before installation.
3) Check if the connecting bolts are loose, if the motor insulation is good, and if there are any obstructions inside the fan pipeline that may hinder rotation.
4) After the fan installation, a trial operation must be conducted. Any abnormal rubbing, bumping, or vibration should be eliminated immediately.
