Intelligent axial flow fan: When harmful gases are detected, the fan automatically alarms and starts. It discharges the harmful gases to ensure the safety and health of workers in enclosed areas. The fan inlet can be connected to the air duct. It can also be used to achieve联动of multiple fans. It can also be customized according to the specific requirements of the customers.
The application forms of T30/T35/T40 axial flow fans are mainly classified according to the application scenarios and functional requirements. Common types include the following:
1. General ventilation and air exchange type
This is the most basic application form of axial flow fans, mainly used for air replacement in enclosed or semi-enclosed spaces such as factories, workshops, warehouses, and basements. By forcing air circulation, it removes dirty air (such as dust, odors, and humid hot air) from the room and introduces fresh air to improve indoor air quality and ensure the comfort of personnel and the safety of the production environment. For example, this type is applicable in scenarios such as removing metal dust from mechanical processing workshops or dispersing humid hot air from textile workshops.
2. Positional air supply / Cooling type
Designed for the local cooling or air supply needs of specific work positions (such as welding stations, assembly operation tables, and areas near high-temperature equipment). It is usually used in combination with position-specific mobile support frames, which can be moved to the target position and directly supply air to the operators, reducing the local environmental temperature and dispersing harmful gases (such as the smoke from welding), improving the comfort of the position operation, and avoiding operators being exposed to high temperatures or dirty environments for a long time.
3. Pipe exhaust / Air supply type
Some axial flow fans can be adapted to pipe systems and used as pipe-type fans. By connecting the air ducts, they can achieve directional exhaust or air supply in specific areas, such as local exhaust systems in buildings (such as bathrooms and auxiliary exhaust for kitchens), and process air flow transmission in production lines (such as material cooling air flow transmission in the light industry sector). These fans need to match the pipe dimensions to ensure that the wind pressure can overcome the resistance of the pipe.
4. Auxiliary heat dissipation
Used for auxiliary heat dissipation of industrial equipment, electrical cabinets, and small refrigeration units. For example, the T30 fan mounted beside the motor housing can accelerate the heat dissipation of the motor, preventing the equipment from being damaged due to long-term overheating; the small T30 fan in the distribution cabinet can remove the heat generated by electrical components in the cabinet to ensure the stable operation of the circuit.
5. Temporary emergency ventilation typeIntelligent axial flow fan
The T30 fan with mobile support frames can be used as emergency ventilation equipment for emergencies (such as temporary maintenance in the factory, ventilation and drying after water accumulation in the basement, and the dispersion of harmful gases at the accident site). Its mobile feature enables it to respond quickly to temporary ventilation needs and make up for the deficiencies of fixed ventilation systems.
Axial flow fans are a widely used general-purpose ventilation equipment with compact structure and stable operation. They are suitable for various ventilation and air exchange needs in different scenarios. The following provides a detailed introduction from the core parameters, structural design, derivative models, and installation and maintenance aspects:
1. Core performance parametersIntelligent axial flow fan
Specifications and air volume and pressure: This type of fan has a wide range of specifications, with 46 varieties, and the number of blades covers 3, 4, 6, 8, and 9 types. The machine number ranges from №2.5 to №10 (the 2.5-blade model is unique, and the rest of the blade types have machine numbers from №3 to №10). The air volume range is 550 – 49500 m³/h, and the pressure range is 25 – 505 Pa, which can meet the ventilation needs of different spaces.
Speed and power: The 3 – 8-blade models are compatible with two types of motor speeds, while the 9 and 10-blade models have only one speed. The motor power varies with the model number and operating conditions. Small models such as №2.5 have a power as low as 0.09 KW, while large models such as №10 can reach 11.0 KW, which can meet the power requirements of different air volume and pressure.
Operating conditions: It is only suitable for conveying non-corrosive and non-severe dust gases. The gas temperature must not exceed 80℃ to avoid component damage and affect the equipment lifespan.
2. Structural design
The fan consists of a motor, wind tube, impeller, bracket, and protective net.
Impeller: It is composed of blades and hub. The blades are formed by stamping thin steel plates and welded on the outer circle of the hub. Different blade numbers correspond to different installation angles. The 3-blade angles are divided into 10° and 15°, etc., while the 4, 6, and 8-blade angles are divided into 15° and 20°, etc. The angle adjustment can adapt to different air volume requirements. The impeller is directly connected to the motor shaft, with high transmission efficiency.Intelligent axial flow fan
Casing: It includes the wind tube and base frame. The base frame has two materials: thin steel plate and profile, which can protect the internal components and achieve stable installation through the base frame, suitable for fixed or mobile installation scenarios.
Protective net: To prevent leaves and other debris from entering the wind tube and damaging the impeller.
Motor: It is a YE3 energy-saving copper core motor.
3. Derivative models
The main derivative is the BT30 explosion-proof axial flow fan. The impeller (except the hub) is made of aluminum, and it is combined with an explosion-proof motor. The switch is selected as an explosion-proof switch or installed away from the explosive area. This model is suitable for industries such as chemical and pharmaceutical, and can be used to discharge flammable non-volatile gases. The installation process is the same as the ordinary T30 axial flow fan, and the safety meets the explosion-proof requirements of special industries.
