Types of fansThe fans find a great application in the common

engineering. They are widely used in the ventilationand air-conditioning installations in houses, public andindustrial buildings; in central and local ventilation ofmines; in pneumotransport; in agriculture, etc.

The fans are an essential part of many technologicalprocesses in the metallurgy, chemical industry andenergetics. They serve for creating of technologicallyclean environments - for production of elements, inradioelectronic and computer machinery, in laborato-ries for tissue cultivation.

Practically, there is no branch of the national econo-my, where fans don't find application.

Main producer of fans in the republic of Bulgaria is"Spartak" joint-stock company, Bourgas.

The fans are working hydraulic turbomachines forair or gas, where the mechanical energy is trans-formed into hydraulic - kinetic and potential. The mainenergy changing element is the impeller, which,according to the direction of the air or gas flowinggoing through it, can be radial, diagonal or axial.Generally the fans with radial and diagonal impellersare called centrifugal fans. They can be single - ordouble - inlet, and the position of their housting areshown on fig.1.

The fans are produced in right-hand version - the im-peller rotates clockwise, as seen from the sucking side(opposite ti the motor position) and left-hand version -the impeller rotates counterclockwise, as seen fromthe sucking side.

1. Flow, Q[m3/h] - the volume of air (gas) trans-ported by the fan per unit of time.

2. Full pressure, Pv[Pa] - increase of the specificenergy of the air (gas), flown through the fan.

3. Static pressure, Pst [Pa] - the differencebetween total pressure Pv and dynamic pressure(kinetic energy)Pd is the difference in the dynamicpressure before and after the fan. The characteris-tics shown in this catalogue are stated for air at nor-mal atmosphere conditions: temperature 293,16degrees K (20 degrees C) and air density p = 1,2kg/m3.

4. Installed power, Nm [Kw] - the power of theused el.motor. This power is with reserve andexceeds the consumed power of the fan about 10 -20%, depending on the model and version of imple-mentation.

General instruction for fan selection

In selection of centrifugal and axial fans capacity,pressure, kind of transported gases (including dust,temperature, aggressiveness, explosiveness and otherspecific features) and also constructive reasons shouldbe stated.

The sequence of choosing a fan is given in the fol-lowing example

EXAMPLE : We need a fan with a flow of Q = 70 000m3/h and total pressure of Pv = 1000 Pa

From the summary aerodynamic characteristics ofthe different versions of fans shown in the catlogue forparameters Q = 70 000 m3/h and Pv = 1000 Pa andother specific requirements, we choose fan VNSN-14.

From the individual aerodynamic characteristics ofVNSN-14 for Q = 70 000 m3/h and Pv = 1000 Pa, we findrotation frequency per minute n = 660 min-1. Theinstalled power of the fan is 30 kw.

The level of sound pressure of the fan for given aero-dynamic parameters is between the curves 85 and 87,5dB/A/. With a simple interpolation the point is foundLpa = 86 dB/A/.

In order to achieve noise level in octaves, we use non-dimensional spectrum, which is given in a table belowaerodynamic characteristics as f(∆Lp)

The sound pressure level in octave spectrum is givenin the formula :

Lp = Lpa + ∆Lp

For the chosen point from the aerodynamiccharacteristic, using nondimensional spectrum wereceive the sound pressure level in octave from 63 to8000 Hz.

6

The sound pressure level of a distance of r = 3 iscalculated according to the formula :

LPA(3) = LPA(1) +20 lg 1

where :LPA(3) - sound pressure level up to 3m distanceLPA(1) - read from the characteristic level of

sound pressure.r = 3m.

The level of sound power is calculated from thelevel of sound pressure by the formula :

LW ≈ LPA + 8where :

Lw - level of sound power For the example : Lw ≈ 86 + 8 Lw ≈ 94 dB/A/

When ordering fan to the manufacturer, the follow-ing characteristics should be stated:

- type of fan- capacity [m3/h]- full pressure |Pa]- installed power [kW]- rotation frequency per minute [min-1]- position of the housting - according to fig.1.- characteristic of the fluid - temperature, explosive

ness dust, adhesiveness of the dust and other specific requirements

- fan equipment - frame, vibrated frame, flexible joints and other.

PURPOSE

Cenrifugal double-intlet fans are intended to com-plete fan section from Sectional air-condioning cham-bers. They can be used also in other ventilation sys-tems. They transport air and gasses, free frommechanical particles, with a maximum temperatureup to 223,16° K (50°C). They can operate in rooms ofclasses PI, Pll, Plla and PIll in accordance with PSTN-87.

Fans of the series type VCD provide a flow of 2000to 100000 m3/h and a pressure up to 1500 Pa.

They are completed with el.motors and startlingequipment with a grade of protection IP44, belts andslide rails for the el.motor.

Protection against direct atmospheric influence isrecommended when mounting.

Ambient temperature from -10°C to + 40°C.
