Stainless steel fan

Stainless steel fan is a kind of fan made of stainless steel anti-corrosion material. The working principle is that when the motor rolls and drives the fan impeller to rotate, the gas between the blades in the impeller also rotates, and these gases are thrown out under the action of centrifugal force. The gas flow rate increases, so that the gas converts kinetic energy into static pressure energy during the activity, and then follows the pressurization of the fluid to convert the static pressure energy into speed energy, the gas is discharged through the exhaust port, and a certain negative pressure is formed in the center of the impeller. Due to the negative pressure at the inlet, the outside gas is immediately replenished under the action of atmospheric pressure, and the gas is continuously discharged and replenished under the action of continuous rotation of the impeller. So as to reach the purpose of continuous blowing. Under equal power, the wind pressure and air volume are generally inversely proportional. Under equal power, if the wind pressure is high, the air volume will be relatively low, while if the air volume is large, the wind pressure will be lower, so that the talent can make full use of the power of the motor.

Structural characteristics

1. The stainless steel fan is mainly composed of impeller, casing, air inlet, motor, connector, heat dissipation fan and other parts.

2. The impeller adopts multi-wing single-inlet centrifugal impeller, adopts excellent galvanized sheet or cold rolled steel plate, and is designed according to aerodynamic principle. The impeller is composed of 10 backward tilting wing blades, curved front plate and flat rear plate. The material is made of high-strength and high-strength materials, excellent steel plate with good durability, strict action, static balance correction, good air performance, high efficiency, and smooth operation.

3. The air inlet adopts convergent streamlined vortex reduction form, with small airflow loss and high working efficiency of stainless steel fan.

4. The stainless steel fan shell is installed and connected with the metal casting of the motor, the heat dissipation blade is installed on the shaft head of the motor, and the outer wall of the metal casting is open. The outlet pipe interface cools the metal castings and shaft heads to ensure the normal operation of the motor at high temperatures.

5. The motor adopts special motor, the fan fluid adopts temperature-resistant materials, and the cooling structure performance is reliable.

Application

Stainless steel fans are mainly used in metallurgy, petrochemical, electric power, urban rail transit, textiles, ships and other fields of the national economy and ventilation in various places.
