Foundry Q235 Carbon Structural Steel Air Inlet Centrifugal Ventilation Fans
Introduction Of Centrifugal Fan
When the fan is working, the airflow enters the blade space from the fan axially, and then rotates with the impeller under the drive of the impeller; on the other hand, it increases energy under the action of inertia, leaves the impeller along the radius, and does work by the centrifugal force generated. The fan is called a centrifugal fan.
The main components of the centrifugal fan are: impeller, casing, coupling and shaft. The impeller is the main work component that generates wind pressure and transfers energy; the casing is mainly used to introduce gas and exhaust gas, and at the same time convert part of the kinetic energy of the gas into pressure energy; the coupling is used to connect the motor and the fan to transmit torque;the shaft is installed with the motor through a coupling and the impeller is fixed.
The centrifugal fan is mainly composed of an impeller and a casing. The impeller of the small fan is directly mounted on the motor, and the large fan is connected with the motor through a coupling or a pulley.
Centrifugal fans generally use single-side air intake and use single-stage impellers; those with large flow can be air-intaken on both sides and use two back-to-back impellers, which are also called double-suction centrifugal fans.
Application
1. As a device with good performance, centrifugal fans are now widely used for ventilation, dust exhaust and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings. The role of centrifugal fans is powerful. When users choose to use them, they also need to start from the characteristics of centrifugal fans and use them in a scientific way to ensure that the fans bring greater benefits to themselves.
2. In the factory, the workshops, warehouses and other departments are equipped with centrifugal fans, which play a role in ventilation, ensure the fresh air in the workshop, and help to purify the working environment and the health of employees. At the same time, the factory warehouse is equipped with centrifugal fans to dry the air to ensure that the mechanical equipment or other industrial products maintain the original quality.
3. Install centrifugal fans in mines and tunnels to re-enter fresh air and exhaust dirty air to ensure air circulation in the mines and tunnels.Centrifugal fans can help dust discharge, ensure air transparency in mines and tunnels, and ensure the health of workers in mines and tunnels.
4. A centrifugal fan is installed in the cooling tower, which not only plays the role of ventilation and ensures the normal operation of the cooling tower, but also plays a positive role in improving the cooling effect of the cooling tower by the large flow wind generated by the centrifugal fan.
5. Main ventilator in coal mine is an important equipment to ensure normal ventilation in underground mine, which not only affects the production capacity of coal mine, but also is very important to the safety of mining industry.
6. Centrifugal fans are widely used in boilers and industrial furnaces. They mainly play the role of ventilation and air induction. On the one hand, they ensure the environment of the boiler room or industrial kiln. On the other hand, they allow the replacement of oxygen-enriched air, which makes the firepower of the boiler or kiln more fierce and saves coal to a certain extent. Wait for power resources to reduce enterprise production costs.

1. It can output high outgas pressure and can work at higher medium temperature, suitable for any industrial occasion where high pressure & high temperature gas needs to be delivered.
2. In the case of common base, the installation is very simple and requires little support from a professional technician.
3. The bearing housing is reserved for the installation position of the temperature and vibration sensors, and the fan operation monitoring device can be conveniently installed.
4. When the airflow resistance is increased, the motor load will be automatically reduced and the motor will not be burnt.
5. Customized design according to customer's performance requirements, and optimized by CFD technology, the energy consumption is lower than similar models.
6. The tight fit between the components and the good sealing performance ensure that the output pressure is not reduced.
7. The impeller is subjected to a high standard of dynamic balance correction to ensure stable operation of the fan.
8. After the production is completed, after running test and vibration value detection, the operation is reliable.
9. There are a variety of options to choose from.
