Product Description

4-79,2×79type centrifugal fan

4-79, 4-2×79 type centrifugal fan use: The 4-79 centrifugal fan can be used for indoor ventilation in general factories and large buildings. It can be used for both input and output gas. The type of gas to be transported is air and other gases that are not spontaneously combustible, harmless to the human body, and non-corrosive to steel materials. No viscous substances are allowed in the gas, the dust and hard particles contained in it are not more than 150mg/m³, and the gas temperature must not exceed 80°C.

Structural features
The fan can be made into two forms clockwise rotation or counterclockwise rotation.
The fan is mainly composed of an impeller, a casing, an air inlet, a transmission, and a direct-connected motor.
1) The impeller is composed of 16 backward-inclined arc-shaped thin-plate blades, a curved front disc, and a flat rear disc, all of which are made of steel plates and have undergone dynamic balance correction. The air performance is good, the efficiency is high, the noise is low, and the operation is balanced.
2) The casing is made in two different forms. The casing of No.3-12 is made as a whole and cannot be disassembled; the casing of No.14-20 is made of two openings, which are divided into two halves along the horizontal plane in the middle, and are fixed by bolts. Connect.
3) The air inlet is made as a whole and installed on the side of the fan. The section parallel to the axial direction is in a curved shape so that the gas can enter the impeller smoothly with less loss.
4) The transmission part is composed of a main shaft, a bearing box, a rolling bearing, and a pulley.

Our Advantages

 

 

Strict quality standards, precision machining, and other spare parts and design maintain product stability, strictly select product parts suppliers, and perfect after-sales service system to allow customers to enjoy a new experience

Our company has introduced the latest research results of the Chinese Academy of Sciences, C4-II ternary flow wing twisted blades, which have high aerodynamic efficiency.
The surface of the ventilator impeller blade is sprayed with advanced super-resistant (CN) metal material to form a wear-resistant, anti-corrosion protection layer on the surface of the blade. The wear resistance of the blade surface is 10 to 50 times higher than that of the ordinary carbon steel material, thereby greatly prolonging the service life of the blade.
