3C fire ventilation and smoke exhaust fan

3C fire ventilation and smoke exhaust fanfeature

1. The HTF (GYF) series fire high-temperature smoke exhaust axial flow fan has the characteristics of excellent performance, good high temperature resistance, high efficiency, less land occupation than centrifugal fans, and easy installation.

2. The HTF (GYF) series of high-temperature smoke exhaust axial flow fans for fire protection have been tested and qualified by the Fixed Fire Extinguishing System and Fire resistant Construction Quality Supervision and Inspection Center. Their performance has reached the high-quality level in China and has been recognized by more than 30 provinces and cities nationwide. This wind turbine is exported to various provinces (cities) and autonomous regions across the country.

3. Excellent high temperature resistance performance: The fan test meets the requirements of GB/T13274-91 "Technical Conditions for General Purpose Axial Flow Fans" and GA211-2009 "High Temperature Resistance Test Method for Fire Exhaust Fans" fire code standards. The fan is designed with a built-in high temperature resistant motor and equipped with a motor cooling system. It can operate continuously for more than 100 minutes at 300 ℃ and continuously for 20 hours/time at 100 ℃ without damage. Widely used in high-rise civil buildings, underground garages, tunnels, subways and other occasions.

4. Wide application range: It can be driven by variable speed or multi speed according to the different requirements of civil buildings to achieve the purpose of dual-use (i.e. ordinary ventilation and high-temperature smoke exhaust for firefighting). The blade type is divided into axial flow smoke exhaust HTF (GYF) - I, II, D1, D2 and mixed flow smoke exhaust HTF (GYF) - III, IV, and can also be made into roof type and silencing type.

5. High efficiency: This series of fans adopts high-quality CAD software and is a new product developed through multi-objective optimization design. Tests have shown that the fan efficiency is greater than 80%, and some large machine numbers are greater than 85%. It also has the characteristic of a flat efficiency curve, which is conducive to energy conservation.

6. Easy to install and requires less space for centrifugal fans: The basic form of this fan is an axial flow fan or a mixed flow fan, which can be directly connected to the air duct or wall mounted. The installation form can be vertical or horizontal, which greatly saves space.

3C fire ventilation and smoke exhaust fanCleaning and maintenance:

1. Disconnect the main power supply, hang the "Do Not Close" sign, and check if the motor grounding wire is in good condition.

2. Firstly, we should adjust the tightness of the belt used for the 3C fire exhaust fan, manually rotate the fan wheel, and investigate whether the transition is stable.

3. Add lubricating oil to the transition section of the 3C fire exhaust fan to ensure the sensitivity and stability of the coupling and bearings.

4. Filter and inside the casing. Regarding the areas where paint has fallen off, it should be repainted.

5. Check whether the opening and closing action of the 3C fire damper is reliable and sensitive, and whether the opening and closing viewpoint of the 3C fire exhaust fan symbolizes clarity.

6. Check and replace the gaskets and sealing fillers between the joint surfaces of the 3C fire exhaust fan, and be sure to add these gaskets and sealing fillers properly.

7. The 3C fire smoke exhaust fan can be manually turned on to check the indicator lights, current and voltage meters for normal operation. It is also necessary to check whether there is any abnormal noise in the operation of the fan's various components and whether the three-phase current values are balanced.

8. Check whether the mechanical opening and closing action of the regulating valve is reliable and flexible, and whether the opening and closing angle markings are clear.

9. Manually turn on the machine to check if the indicator lights, voltage, and current meters are working properly, if there are any abnormal sounds from the operation of the 3C fire exhaust fan components, and if the three-phase current values are balanced.

10. Conduct a comprehensive inspection of the components inside each remote control box to ensure they are functioning properly.

The daily cleaning and maintenance of 3C fire exhaust fans are very important, as they can ensure the normal operation of the equipment and increase its service life.
