What is a high temperature centrifugal fan?

2021-08-13

High temperature resistant centrifugal fan is a kind of centrifugal fan commonly used in our lives, but many of us may not have seen it, because it is used in high temperature workplaces, which is a basic need in industry, so it is more important to transport gas in industry , So its structure is closely related to our body, so let us and our editor to popularize this kind of high temperature resistant centrifugal fan.

The high temperature resistant centrifugal fan is a special fan specially used in high temperature working places. The material has strong resistance to high temperature and high pressure. High temperature resistant centrifugal fans mainly include stainless steel high temperature resistant centrifugal fans, transmission high temperature resistant centrifugal fans, centrifugal high temperature resistant centrifugal fans, etc. High temperature resistant centrifugal fans are widely used in chemical, petroleum, metallurgy, forging, electric power, nuclear power plants, environmental protection and other fields. The gas transported is air or other gases that are not spontaneously combustible, non-explosive, non-entangled, harmless to the human body, and corrosive to steel materials. It can also be used in various industries to transport hot gas, steam and smoke that are non-corrosive, non-self-igniting, and non-sticky substances. Other similar performances can also be selected, but the temperature of the conveying medium must not exceed its rated temperature range.

The high temperature resistant centrifugal fan is mainly composed of impeller, casing, air inlet, motor, connector, cooling blade and so on. The impeller adopts a multi-wing single-import centrifugal impeller, which is made of high-quality galvanized sheet or cold-rolled steel sheet. The blades are designed according to the principles of aerodynamics. The impeller consists of 10 backward-inclined airfoil blades, a curved front disc and a flat rear disc. The material is made of high-strength, high-quality steel plate with good durability, which has undergone strict dynamic and static balance correction. The air performance is good, the efficiency is high, and the operation is stable. The air inlet adopts the convergent streamline vortex reduction form, the air loss is small, and the high temperature resistant centrifugal fan has high working efficiency. The shell of the high temperature resistant centrifugal fan is connected with the motor through metal casting, and the motor shaft head is provided with cooling blades. The outer wall of the metal casting is equipped with water inlet and outlet pipe connections to cool the metal casting and the shaft head to ensure the normal operation of the motor at high temperatures.
