Operating  principle  of  large  industrial  fan

Large industry fan can push large amounts of air to the ground and form a horizontal movement of air layer at a certain height, to create a integral air circulation. The advantages are the full coverage of ground and three-dimensional circulation of air. If being installed at place with poor ventilation, the fan can totally discharge gases such as heat, unpleasant odor, chokedamp, dust, etc. out of the plant building, and at the same time, can exchange the indoor air with the fresh outdoor air, to continuously provide fresh and clean air and increase the air oxygen content for the workshop. Severe working environment has been improved and employees’ health has been protected, and the work efficiency will be improved.


Safety Precautions

Safety precautions prevention all risks

Fastener: All fasteners, which adopt High strength industrial bolts, have more than decuple of actual stress.

Steel wire traction: Stress intensity of wire cable can reach 1000KG, and double protection is set for each connection point.

Protective structure of the fan body: Upon unexpected accident, The safety link of the fan can play a protective role to prevent any component from slipping off  When  an unexpected situation occurs.

I-shape safety structure of the fan blade: Reconnect all the blades to the chassis, to form the integral structure.

If any abnormality occurs during a test, the inverter control system will automatically alarm and stop running.

II. Safe Installation

GERY has an experienced team with electric, mechanical and architectural engineer staff, who can make stress analysis according to different building structure and provide propriate installation  solution;  We can also carry out installation and construction for various buildings meeting the installation conditions. We have strict operation specifications and installation standards during our operation process, our professional skills and high requirements will remove all your suspicion

Installation plan—customized services;

Installation procedure—simple, clear and scientific;

Upon demands of customers, comprehensive tests on site for airflow volume, wind speed, noise, etc. can be made after installation, and test reports can ben issued.

 

Precautions for Large Industrial Fans


I. Large fan products are characterized with low speed and large torque during running. Switch on and switch off must be in accordance with reasonable and normal switch steps. Especially remember that rotate speed of the inverter must be switched to lowest before switch off, and the power off knob can be switched to the “stop” position only until the fan has turned to still from normal running, to avoid potential safety risks caused by direct and sudden shutdown.

II. Large fans generally can be installed either whether there has crane or not have, but the safety height left from the top of the crane to the roof for installation shall be 1.5 meters or more.

III. If building roof of the installation site hasn’t been insulated, fan mounting extension rod shall be considered to use for installation, keep the fan blades as far away from the roof as possible to avoid the upper hot air being driven to the operation area below by the large fan.
