Product Description

Dust removal induced draft fan model and parameters, 2 fan motor power: 2.2kw, 3kw, 4kw, 5.5kw, 7.5kw, 11kw, 15kw, 18.5kw, 22kw, 30kw, 37kw, 45kw, 55kw, 75kw, 90kw, 110kw, 132kw , 200kw, 220kw, etc. The fan unit has the following models: 4-72no 2.8a (1.5kw), 4-72no 3.2a (2.2kw/1.1kw), 4-72no 3.6a (3kw/1.1kw), 4-72no 4a (5.5kw/1.1 kw), 4-72no 4.5a (7.5kw/1.1kw), 4-72no 5a (15kw/2.2kw), 4-72no 6a/6d (4kw/1.5kw), 4-72no 8d (18.5kw/5.5kw) /3kw), 4-72no 10d (18.5kw/55kw/7.5kw), 4-72no 12d (45kw/18.5kw), etc. The number of kilowatts of the motor is in brackets.
The fan of the bag filter is an important part of the bag filter, and it is also an important indicator for judging the dust capture ability. The performance of the fan is different, and the selection method is also different. In addition to meeting the requirements for the air volume and pressure loss of the dust removal system, the fan should also consider the requirements of the fan itself for efficient operation. It should be determined according to the dust removal system and the selection parameters of the fan manufacturer. When the air volume and air pressure of one fan in a production line cannot meet the requirements, two fans (two identical fans) can be connected in series or parallel to meet the requirements of air volume or air pressure.
The dust removal fan can absorb the dust in the workshop, prevent the inhalation of the human body, and is beneficial to human health. The working principle of the general centrifugal fan is basically the same. When the impeller rotates at a high speed, all parts of the air in the impeller are also driven to rotate together. At this time, the air at the center of the impeller will be thrown to the edge of the impeller due to centrifugal force. , a vacuum is formed at the center of the impeller, so the external air continuously flows in under the action of the pressure difference and is supplemented to the center of the impeller, so that the fan has the ability to inhale air. Since the speed of the air leaving the impeller blades during rotation is much greater than the airflow speed in the space around the impeller, part of the kinetic energy of the gas is converted into static pressure energy during the movement. The space presents a positive pressure, so that the fan has the ability to transfer the gas into the guide wheel, and in the guide wheel, part of the kinetic energy is converted into static pressure energy, and then flows into the motor, and at the same time, the motor is dissipated and pressed out through the outlet.
