Product Description

4-2X79 centrifugal fan

4-2X79 centrifugal fan is a centrifugal fan designed with a double-suction air inlet. The fan is mainly composed of an impeller, casing, air inlet, and other components. The fan can be made into two forms clockwise rotation and counterclockwise rotation. The air outlet position can be made into three fixed directions 0, 90, and 180. The impeller is made of 16 backward inclined arcs-shaped iron plate blades welded with arc-shaped front plate and flat plate chassis and is subject to strict dynamic balance correction, It has good air performance, high efficiency, and low noise. The fan is generally used for indoor ventilation of high-rise buildings, and also for gas input or output of dust-free workshops and large buildings in factories. The conveying gas is air and other non-spontaneous combustion, harmless to the human body, and non-corrosive gas. There shall be no viscous substances in the gas, the temperature of the extracted gas shall be ≤ 8O ºC, and the dust and hard particles shall be ≤ 150/m3.


4-2 × 79 centrifugal fan Purpose:
4-2x79 centrifugal fan This type of fan is mainly used for indoor ventilation of general factories and large buildings and can be used as input gas and output gas. No viscous substances are allowed in the gas, and the dust and hard particles contained are not more than 150 mg/m ³. The gas temperature shall not exceed 80 ºC.


4-2 × 79 types of centrifugal fan structure:
№ 3~6, mainly composed of impeller, casing, air inlet, and other parts equipped with a direct-connected motor. № 7~20 has not only the above parts but also the transmission part. The impeller is composed of 16 backward-inclined circular thin plate blades, a curved front plate, and a flat rear plate. The № 3-12 casing is integral and cannot be disassembled; The casings of № 14~20 are made of two openings, which are divided into two halves along the horizontal plane of the split and connected by bolts. The air inlet is made into a whole and installed on the side of the fan. The section parallel to the axial direction is curved, which can make the gas enter the impeller smoothly with less loss. The transmission part is composed of the main shaft, bearing box, rolling bearing, and pulley.


4-2 × 79 centrifugal fan type:
This type of fan can be made into two types: right rotation and left rotation. № 3~6 are both made into one type when leaving the factory. The user can install it in the required position according to the requirements, and it is not necessary to indicate when ordering; The adjustment range of the air outlet position of № 3~4.5 is 0 °~225 °, with an interval of 45 °. The adjustment range of the air outlet position of № 5~6 is 0 °~225 °, and the interval is 22.5 °. The transmission mode of № 3~6 is type A, and that of № 7~8 is type C. The positions of air outlets № 7~20 are made into three fixed types: 0 °, 90 ° and 180 °, which cannot be adjusted, and attention should be paid when ordering; № 10-20 transmission mode is E type; There are three types of double air inlet type № 5~20 with fixed air outlet positions: 0, ° 90 and ° 180 °. The transmission mode is E-type transmission, which shall be noted when ordering.

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.


Our company adopts computer simulation calculation and quasi-ternary flow theory, we correct the blade shape and calculate coordinate parameters of its shape, then make the core mold and the external pressure mold of the blade, and the blades are formed by hot pressing. According to a large number of experiments, the tilting blade has a larger lift-to-drag ratio than the original organic blade type and is the best choice for the airfoil blade.

The blades are welded with high-strength carbon steel material. The petiole is treated with high-quality carbon steel. So that the blade maintains the strength and rigidity of the steel blade when ensuring the corrosion resistance and wear resistance of the blade. Moreover, it effectively protects the blade from corrosion resistance and wear resistance in a humid air environment, and improves the operating life of the ventilator.
