(Also popularly known as vacuum Cleaners)
WHAT IS VACUUM ??
Vacuum is space which has no matter in it, ie any space
in which pressure is lower than atmosphere pressure
Atmospheric pressure is –
1 kg/sq.cm :1 bar :760 nun of mercury
:10,000 mm of water :1,01.350 pascal

3. Principle utilized by Vacuum Cleaner
_____________________________________________________________
All liquids & gases flow from high pressure
area to low pressure area.
Common Example : Drinking thru a straw
Volume of air
It is the quantity of air in liters for a given unit of time, which enters the vacuum
cleaner or which the fans exhaust.
1000 liters : 1 cu.m.
3600 seconds : 1 hour
e.g. 35 liters/s = 126 cu.m/lh = 0.277 liters/s

11.  Transport velocity and capture:
Velocity is the number of meters a particle travels in a unit of time. In
suction, it is decided by the volume of air and the diameter of the hose a')
velocity is volume of air divided by the area of hose.
Capture velocity: This is the velocity of the air that is needed at the inlet or
at the nozzle, to capture the product and carry it away. It will depend on:
the size of particle
the specific gravity
the charge the particle catties
e.g. III grinders or mills, the loose particles have a speed. The capture
velocity at the nozzle has to be greater in order to suck them in.
Selection of insufficient velocity will cause the product to settle out on the
interior of the piping system and clog it.
 For ordinary dust, we shall use 20-21 meters/second and for heavy dust
(Cement, Metal shavings) up to 35 meters/second.

12. Calculating hose size :
 How to calculate the hose size:-
e.g.:
The machine has the air flow rate of 68 liters/second
we know that Velocity = Volume / Area.
 Therefore, Area = Volume / Velocity
= 0.0019 sq. meter.
 Area of a circle = 3.14 x sq. of radius
 Therefore, radius = sq. root of (Area x 3.14)
= 0.0248 meter
= 24.87 mm
We multiply the radius by 2 to get the diameter
Hence, the diameter is 49.7mm i.e.50mm
Hence, the machine to use will be GS 83 or GB 733 or any
higher machine.

14. Selection of Vacuum Cleaners
Single-phase for flexible and in-expensive cleaning
The single-phase motor driven machines are designed for flexibility and are easy to
maneuver. They are primarily used for occasional cleaning of manufacturing areas
or for overhead cleaning.
The single-phase motors are normally fitted with carbon brushes. Single-phase
motors are also available in a brushless version for durability and explosion-proof
applications.
Three-phase for continuous operation
The three-phase machines are designed for continuous use e.g. for process-
integrated cleaning or fixed installations with several inlets in use at the same time.
The three-phase machines can be subdivided into side-channel blowers where the
vacuum fan is mounted directly on the motor, and turbine motors where the motor
and the fan units are connected via a drive belt.

15. Side-channel blower or turbine machine?
Choosing a machine equipped with side-channel blower or turbine depends on
the cleaning task at hand.
A side-channel blower has a direct relation between vacuum/airflow and rated
power (kW)
A turbine solution provides you with the ability to change the ratio between
vacuum and airflow independent from the rated power by changing the
combination of turbine and motor.
Example 1: light dust requires high airflow and less vacuum
with a turbine solution - 4,0 kW rated power (197 l/sec 14,7 Kpa)
with a side-channel solution - 7,5 kW rated power (205 l/sec 27,5 Kpa)
Example 2: heavy debris requires less airflow and high vacuum
with a turbine solution - 3,0 kW rated power (87 l/sec 22,5 Kpa)
with a side-channel solution - 4,0 kW rated power (100 l/sec 27,0 Kpa)
