Principle of Operation

Two profiled rotors counter-rotate in a machined housing with close-tolerances.Each rotation of the rotor set displaces a fixed volume of air from inlet to outlet.

from) the process to which it is connected.


6/69

Operating principle

The top rotor confines a volume of gas on the suction side

PD Blowers6


7/69

Operating principle

The top rotor confines a volume of gas which is isolated from the suction and delivery

PD Blowers7


8/69

Operating principle

This is a VOLUMETRIC machine with no internal compression

PD Blowers8


9/69

Operating principle

The rotors, synchronized by the pinions, turn in the opposite direction:

1. without any contact between them

2. without any contact with the fixed parts

Characteristics

Cubic capacity: This is expressed in l/revolution (litres per revolution)

This volume, for 1 revolution of the Blower drive shaft, is equal to

the following:

For the bi-lobes : to the green surface x length of the Stator x 4

For the tri-lobes : to the green surface x length of the Stator x 6

PD Blowers15


16/69

Characteristics

Volume generated : Qve expressed in m3/min.

Qve in m3/min. = Cubic capacity in m3 x Speed in rpm.

The speed to be taken into consideration is the exact speed of the

shaft end under operating conditions.

The cubic capacity has to be converted from litres to m3.

PD Blowers16


17/69

Characteristics

Power absorbed: Pabs is expressed in kW.

This is the product of the volume generated withwhich is the difference in pressure between the suction and delivery flanges.

p∆

Pabs in kW = Qve x p∆

Torque = Power / Speed

For a Blower:

=ve

Torque = Cubic capacity x Speed xSpeed

p∆

Consequences on behaviour

SNH

If the pressure remains constant and the speed changes:

.ambient air at 20 C.

At a speed of: 1500 rpm 3000 rpm

Actual flow rate: 7 20 m3/min. 17 m3/min.

Abs. power: 12.75 kW. 25.5 kW.Heating: 47°C. 40°C.

Delivery temperature: 67 C. 60 C.

21/69


When the Blower creates a VACUUM or PRESSURE:

Example: an SNH 6 that operates at a of 0.4 bars, at a speed of 1500 rpm and that sucks in airat 20°C

Under: Pressure Vacuum

p∆

Actual flow rate: 7.20 m3/min. 6.46 m3/min. Abs. power: 12.75 kW. 12.75 kW.Heating: 47°C. 87°C.Deliver tem erature: 67 C. 107 C.

PD Blowers21


22/69


SNH

The difference in temperature between operation under VACUUM and operation under PRESSUREis due to:

The lower the weight, the greater the heating.

PD Blowers22


23/69


SNH

The Blower has a suction filter that clogs up:

Exam le: an SNH 6 that o erates at a deliver ressure of 1 bar at a s eed of 2500 r m and that sucks in ambient air at 20 C

With a: Clean filter (no vacuum) Dirty filter (0.1b vacuum) Actual flow rate: 12.33 m3/min. 11.80 m3/min.

. . . . .Heating: 116°C 147°C.Delivery temperature: 136°C. 167 C.

The soiling or clogging-up of a filter may cause the complete destruction of a Blower.

Operating clearances

THE 3 TYPES OF CLEARANCES

Clearances between stator and rotors

1 Lateral clearances2

Clearances between rotors3

PD Blowers25


26/69

Characteristics

There is no internal compression but a simple transfer of gas from suction to delivery.

The Blower does not make any pressure or any vacuum.

It is the load losses (restriction to flow) that create the pressure or

.

As there is no contact in the com ression chamber, there is no lubrication

needed in that chamber

Therefore this type of Blower has no traces of oil or lubricant in the

com ression chamber.

Market Covera e:• Existing IR dealers will market this product as a complimentary

product offering to T30 & LIS & MIS range since the customerprofiles are similar.•

personnel directly .Key Accounts list already circulated to IR salesforce.Same wil l also be circulated to all dealers.

• Initially dealers wil l give back to back orders to IR,at a later date

basis their comfort level the could stock orders for fast movinmodels.• We are creating three service specialits for PD blowers,who in

turn will t rain IR & distributor sales . These service specialists wil lbe trained in June.

• Basis the init ial sales traction IR to stock parts at Naroda taking

guidance from global team for established norms & stockingrecommendations.

• At a later stage, dealers would stock spares.
