How to customize Galvanized Sheet Metal Negative Pressure Fan to meet specific industry needs for special working conditions?

Customizing Galvanized Sheet Metal Negative Pressure Fan to meet specific industry requirements for special working conditions requires consideration and design from the following aspects:
1. Determine the working condition requirements
Firstly, it is necessary to have a detailed understanding of the specific industry requirements and operating conditions of the customer, including but not limited to:
Environmental conditions: such as temperature, humidity, presence of corrosive gases, etc.
Ventilation demand: Determine the required fan size and exhaust volume based on the size of the space and the amount of gas to be discharged.
Noise requirements: Different industries have different restrictions on noise, and it is necessary to ensure that the noise level of the fan during operation meets relevant standards.
Installation methods: wall installation, roof installation, or other special installation methods.
2. Choose materials and design
Galvanized steel plate thickness: Select the appropriate thickness of galvanized steel plate according to the corrosive strength and wind pressure requirements of the working conditions to ensure the strength and durability of the fan.
Blade design: Design reasonable blade shapes and angles based on ventilation and wind pressure requirements to improve ventilation efficiency and reduce noise.
Motor selection: Choose the appropriate motor type and power based on power and energy efficiency requirements to ensure stable operation and energy-saving effect of the fan.
3. Customization of special functions
Explosion proof design: In flammable and explosive environments, it is necessary to add explosion-proof design to the fan to ensure production safety.
Dustproof and Waterproof: For environments with high levels of dust or water, fans with higher levels of dust and waterproof can be customized to protect internal motors and components.
Variable frequency speed regulation: According to actual needs, the variable frequency speed regulation function can be customized to adjust the fan speed and air volume under different working conditions.
4. Customized installation accessories
Bracket and fixing parts: Customize suitable brackets and fixing parts according to the installation method and site conditions to ensure the stable installation of the fan.
Pipeline connection: If it is necessary to connect with the exhaust duct, corresponding connectors can be customized according to the size and material of the duct.
5. Testing and Verification
After customization, it is necessary to conduct performance tests on the fan, including testing of ventilation volume, air pressure, noise and other indicators, to ensure that it meets customer needs. Conduct environmental adaptability testing under special working conditions, such as high temperature, high humidity, corrosive gases, etc., to ensure the stability and durability of the fan.
