An explosion-proof axial flow fan is a special type of fan designed for use in areas where flammable and explosive substances are present; the most common industries that utilize them are petroleum and chemicals. Its main function is to prevent sparks generated at the motor’s wiring terminals, the stator and rotor, or other components during the startup and operation of the fan from coming into contact with flammable and explosive gases in the surroundings, thereby avoiding safety accidents. Advantages of explosion-proof fans: High reliability: Apart from the impeller, the vortex air pump has no other moving parts, and the impeller is directly connected to the motor without gears or belts, resulting in high reliability and almost no need for maintenance. Low vibration: High mechanical precision, with all components of the rotating parts designed with extreme precision for balancing; as a result of testing and calibration, the vibration level is very low. Low noise level of the vortex fan: It uses a low-noise motor for direct drive, and both the inlet and outlet are equipped with built-in silencers to reduce noise during operation. Over 30 years of manufacturing experience, combined with strict quality control, ensures that all components meet the highest quality standards. Meanwhile, to ensure performance, every vortex blower undergoes an operating test before leaving the factory. Working principle of the all-air high-pressure blower: The high-pressure blower is a rotary vane air pump that can both blow and suck air. Its special blade design enables it to deliver high pressure, large airflow, low noise levels, and resistance to high temperatures. The pump features excellent insulation performance, easy installation, and high stability. The gas passing through it is oil-free and dry, ensuring top-quality output. The high pressure and strong suction are generated by the unique design of the impeller. Air suction function: Absorption of waste gases in screen printing machines and welding processes, wire suction from looms, photoengraving, transportation of powders and particles, absorption in printing processes, industrial dust collection, vacuum dehydration, bookbinding machines, treatment of leftover fabric, milk carton filling machines, tofu manufacturing equipment, holding of processed items, construction sites, fabric ironing machines, gas decomposition. Blowing function: Combustion of gas and heavy oil, drying of bottles in bottle washing machines, blowing of paper or cloth strips, air knives for drying, air cushions in cutting machines, aeration during livestock manure fermentation, conveyance of documents, stirring of electrolyte solutions, oxygen supply in aquaculture ponds, easy removal of formed products after stamping in punch presses, transportation of powders and granules, waste disposal in incinerators, blowing and suction of flue gases, drying of vehicles after washing, forced drying in printing machines, and drying after cleaning. When selecting an explosion-proof fan, the following points should be taken into consideration: 1. Determine the type of fan based on its intended use. For example, when conveying clean air, a standard ventilator for general ventilation can be used; when conveying corrosive gases, a corrosion-resistant ventilator should be selected; when conveying flammable gases or dusty air, an explosion-proof ventilator or a dust-extraction ventilator must be chosen. 2. Determine the fan model based on the required air volume, dust load, and the selected type of fan. 3. To facilitate the connection and installation of the ventilator with the system pipes, an appropriate outlet direction and drive method for the ventilator should be selected. 4. Explosion-proof fans | When selecting a fan, it is necessary to ensure that it meets the requirements regarding air volume and pressure. When choosing a Hebei-made fan, one should pay attention to selecting a ventilator with relatively low noise levels.
