Business and axial
Depending on the design and on the direction of the air masses in the work wheel, the inventugns are classified as radial, diagonal, axial and diametrically. As a rule, in practice, the general name is used for radial and diagonal entoations – centrifugal devices.
Such entangles include a VC fan 14 46.
The masses of air that fall on the working shoulder blades of the axial impudence do not change the direction of movement, and it remains parallel to the axis of the turnover. During centrifugal ventilation, air enters the entrance, moving along the axis of rotation, but changes its direction and leaves, directed radially. In the diametrical entarlations, the air enters along the entire length of the rotor, moves to the output and movement of air the same as in centrifugal ventilation.
One -sided and bilateral
As you know, each fan has a sucking and supervisory modes, since depending on the method of connecting and placing ventilation holes, it can work in transmission mode or in air sucking mode. With centrifugal ventilation, according to how air enters the working wheel, one -sided and bilateral suction can be achieved.
Depending on the direction of the turning of the working rotor, the intrigues are with right or left rotation.
Classification by environmental properties
Depending on the physical and technical properties of the ventilated environment, the integrades are divided into:
The entourage used to throw air and other gas mixtures, the activity of which in relation to normal carbon steel does not exceed air aggressiveness;
Corosion -resistant entolations for throwing gases and air, contaminated with chemically – active impurities;
Businesses for use in explosive media, designed to throw out some explosive air mixtures;
Polvo entangles – for throwing air and gas masses containing crushed impurities and particles of mineral origin.
