Ludaofeng 11-62 (A) Series Oil Fume Multi-wing Fan Product Overview
The 11-62 (A) series of low-noise multi-wing centrifugal fans are designed and manufactured by our factory to meet the needs of the increasingly purifying industry and environmental protection and noise reduction. The multi-objective design method of adopting various aerodynamic parameters such as noise and efficiency is designed. , To achieve the best overall performance matching, so as to have good aerodynamic performance. The wind blade is strictly rectified by dynamic balance and has the characteristics of stable operation, low noise, large flow, small vibration, long life and so on. Widely used in kitchens such as unit canteens, hotels, restaurants, restaurants and other public places for exhausting, fume extraction or ventilation. It is also suitable for food machinery, chemical machinery, plastic machinery and other production equipment. It has a wide range of applications and strong applicability. . The medium to be transported is air or other non-self-igniting gas that is harmless to the human body. The medium does not contain viscous substances, the temperature is ≤80 ° C, and the dust and hardness particles are not greater than 150mg / m °.
Form of fan
The 11-62 (A) series fans are designed with seven machine numbers No2.8, 3, 3.5, 4, 4.5, 5, and 6. The fan can be made into right-handed and left-handed forms. When viewed from the motor, the impeller rotates clockwise into a right-handed fan, which is indicated by "right"; otherwise, it is "left". The position of the air outlet of the fan can be made into 0 °, 90 °, and 180 °. The fan is directly driven by the motor, that is, the transmission mode is A type.
Structure of the fan
The fan is mainly composed of an air inlet, an impeller, a casing, and a motor.
Impeller: It is made of steel plate, and is made of 40-80 thin-plate circular-arc blades, which are riveted with the wheel disc and wheel cover. After dynamic balance correction, it has good aerodynamic performance, low noise and stable operation.
Chassis: Welded into high-quality steel plate to make the whole structure, and the volute part of the chassis adopts new sound-absorbing structure, which has good sound-absorbing effect.
Air inlet: Convergent streamline made of ordinary steel plate and welded to the front cover to form an integrated structure.
