[High temperature fan] High temperature fan use High temperature fan structure High temperature fan installation
High temperature fan use:
1. It is used in drying industry, boiler industry, cleaning industry, coating industry and food drying industry.
2. The operating temperature is between 100℃-180℃.
3. The gas to be transported is air or other gas that is not self-igniting, non-self-exploding, non-entangling, harmless to human body, and non-corrosive to steel materials. It can also be used to transport non-corrosive, non-self-igniting, non-viscous hot gas, steam and flue gas in various industries. Others with similar performance can also be selected, but the temperature of the conveying medium shall not exceed its rated temperature range.
4. No viscous substances are allowed in the gas, and the dust and hard particles contained are not more than 150mg/m3. If the dust content is large, a dust removal device that is not less than 85% ready must be installed in front of the fan to reduce the dust content of the flue gas entering the fan, so as to improve the life of the fan.
High temperature fan structure:
1. The high temperature fan is mainly composed of impeller, casing, It is composed of air inlet, motor, connector, cooling fan and other parts.
2. The impeller adopts multi-wing single-entry centrifugal impeller, which is made of high-quality galvanized sheet or cold-rolled steel sheet. The blades are designed according to the principle 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-quality steel plate with high strength and good durability, and has undergone strict dynamic and static balance correction. Good air performance, high efficiency and smooth operation.
3. The air inlet adopts a convergent streamlined eddy-reducing form, the airflow loss is small, and the high temperature fan has high working efficiency.
4. The high temperature fan casing and the motor are installed and connected by metal castings, the cooling fan blades are installed on the shaft head of the motor, and the water inlet and outlet pipe interfaces are set on the outer wall of the metal casting to cool the metal casting and the shaft head. , to ensure the normal operation of the motor at high temperatures.
5. The motor adopts special high-temperature motor, and the fluid part of the high-temperature fan adopts temperature-resistant material, and the cooling structure performance is reliable. Compared with other boiler induced draft fans, it has the advantages of simple structure, convenient maintenance and high cost performance.
High temperature fan installation:
1. This high temperature fan has two forms. Viewed from the side of the motor, if the impeller rotates clockwise, it is called a right-handed fan, and it is indicated by “right”; if the impeller rotates counterclockwise, it is called a left-handed fan, and is indicated by “left”.
2. The outlet position of the high temperature fan is indicated by the angle of the air outlet of the casing. Fans No. 1.5-6 are made into an adjustable type when they leave the factory, and the user can install them in the required position according to the requirements. The adjustment range of the air outlet position is 0°～255°, and the interval is 45°. The transmission mode is “A” type direct drive.
