Fan type - centrifugal fan

 

The working principle of a centrifugal fan is based on centrifugal force. When the fan impeller rotates, the gas is accelerated and thrown out under the action of the impeller, thus forming an airflow. This type of fan has many advantages, such as being able to generate high pressure under the same power input, effectively overcoming resistance in the system, and suitable for situations that require high-pressure air supply or exhaust.

 

Rated voltage -400V

 

The design with a rated voltage of 400V enables it to adapt to a wide range of power supply environments. This voltage level is quite common in many industrial and large commercial places. It ensures that the wind turbine can operate stably when connected to the power system, reducing the risk of faults caused by voltage mismatch, such as motor overheating and unstable speed.

 

Size - Blade diameter 630mm

 

The blade diameter of 630 millimeters is a key dimensional parameter. A larger blade diameter means that the fan can push more air with each rotation. This helps to improve the air output capacity of the fan, which has significant advantages in application scenarios that require a large amount of air circulation, such as large air conditioning systems, industrial ventilation and cooling systems, etc.

 

Input power -3700W

 

The input power of 3700W indicates that the fan has strong power support. A higher power input enables the fan to operate stably under complex working conditions, such as in scenarios where significant resistance needs to be overcome or where rapid air circulation and ventilation are required. Meanwhile, a reasonable power design also takes into account energy utilization efficiency and avoids unnecessary energy waste.

 

Speed -1420rpm

 

The 1420rpm speed design has been carefully optimized. This speed ensures that the fan can generate sufficient air volume while also helping to control the noise level during fan operation. The reasonable selection of rotational speed also matches the overall structure and performance of the fan, ensuring the stability and reliability of the fan during long-term operation.

 

  • Product Features

 

Efficient aerodynamic design

 

The impeller and housing components of the R3G630-FB32-03 fan have undergone careful aerodynamic design. The blade shape, angle, and quantity of the impeller have been optimized to effectively convert the power of the motor into kinetic energy of the air, thereby improving the efficiency of the fan. The design of the casing also helps to guide airflow, reduce energy loss during air flow, and achieve efficient air output and pressure accumulation.

 

High quality motors and drive systems

 

The high-performance motor equipped is the core of the stable operation of the fan. The manufacturing process of the motor is exquisite, using high-quality materials and having good heat dissipation performance. This enables the motor to maintain stable output power during long-term operation without performance degradation due to overheating. At the same time, the drive system of the motor can accurately control the speed of the fan and flexibly adjust it according to actual needs, further improving the energy efficiency of the fan.

 

Excellent structural stability

 

The overall structural design of the fan is sturdy and stable. The shell is made of high-strength materials, which can withstand a certain degree of external impact and are not easily damaged. The internal impeller and other components are firmly installed, and there will be no looseness or displacement during high-speed rotation, ensuring the safe operation of the fan. This structural stability also helps to extend the service life of the fan and reduce maintenance costs.

 

Ability to adapt to multiple environments

 

In addition to being able to adapt to common power environments with a rated voltage of 400V, this fan also has good adaptability in environmental conditions such as temperature and humidity. Whether in high-temperature industrial workshops or in environments with high humidity such as commercial building basements, the R3G630-FB32-03 fan can operate normally. The protection level and material selection can resist the erosion of dust, water vapor, etc., ensuring that the performance of the fan is not affected.

 

  • Application scenarios

 

Ventilation of large industrial plants

 

In large industrial plants, the production process often generates a large amount of heat, dust, and harmful gases. The high air volume and high pressure characteristics of the R3G630-FB32-03 fan can effectively discharge these polluted air from the factory building while introducing fresh air. For example, in places such as steel plants and chemical plants, the fan can be installed on the top or side of the factory building to form a good ventilation system, improve the working environment inside the factory building, and ensure the health of workers and the normal operation of production equipment.
