The

main remplacement parts are interchangeable:

This

enables easier

disassembly-assembly operations and replacement without changing the

in

contact with gases are free of

zinc, copper and cadmium.

The

other construction materials include cast iron, aluminium alloy, stainless

steel, fluorocarbons

(FPM),

Single-stage

rotary

vane

pump

The

pumping

cycle

is

given

below:

Inlet

Transfer

Compression

Exhaust

Operating principle of

the

rotary vane pump

This

is

a volumetric pump, with a functional

part

composed of:

- A

hollow

cylindrical stator with inlet

and

exhaust valves.

- A rotor mounted eccentrically inside the stator for pumping.

-Two vanes sliding

in

the rotor, forced against the stator

by

centrifugal force

and springs.

In.

~Exh.

As the vane passes in front

of

the

inlet orifice, an increasing space

is

formed into which the gas from the

chamber

to

be evacuated expands.

When

the second vane passes, the

space

is

closed.

The gas trapped in the space

between the

two

vanes

is

transferred

to the exhaust orifice

as

the rotor

rotates.

The space communicates with the

exhaust, which

is

fitted with a valve:

the gas

is

compressed until the safety

valve

is

opened.

The

gas

is

expelled into the oil

casing when the pressure

is

sufficient

to open the valve.

Application

Single stage rotary vane pumps

are

the best choice for continuous pressures

above

1.0

Torr (1,3 mbar),

as

well

as

applications where large amounts

of

condensable gases

are

present.

Two-stage

rotary vane pump

To

improve

the

backing pressure and flowrate at low

pressure,

two

stages

are

connected

in

series.

The

second

is

similar

to

the

first both structurally and

operationally.

The

gases

pulled

in

by

the

first (low

pressure)

stage are transferred

to

the

second (high

pressure)

stage and discharged through

the

high pressure

(HP)

valve.

In.

Low

pressure

stage

High

pressure

stage

Application

Two

stage rotary vane pumps are

the

best

choice for application requiring

an

ultimate vacuum

as

low

as

10.3

Torr

(1.33 x 10.3 mbar).

Note:

when operating a two stage vane pump continously, greater

than

half

an

hour,

above 1.0

Torr,

the

unit should

be

equipped with

an

oil

mist

eliminator and

oil return

system,

see

oil draining kit

(page

63), or a single stage pump should

be

used.

Its

function

Choosing

the

right

oil

Lubrication

and

anti-noise

device

Oil

has

several important functions

in

the

pump:

-

It

lubricates mechanical components (bearings,

seals,

rotor, vanes, etc.).

-

It

makes

moving parts relatively tight by limiting internal leakage.

-

It

carries away

the

heat produced by

the

compressed

gases.

Not

all oils produce

the

same

ultimate pressure

in

a given pump. Ultimate pressure

depends

on

the

saturated vapour pressure of

the

oil,

its

viscosity and

its

ability

to

dissolve gases.

Good pumping conditions are related

to

the

type

of

oil

used.

The

choice depends on:

-Expected pump performance.

-Chemical aggression and corrosion

of

pumped gases.

-Accessories

used.

-Desired maintenance intervals and total operating

cost.

ALCATEL

has

selected various

types

of oil for

its

pumps

(see

page

67).

The

pump

is

equipped with a

lubrication

system

which regulates

the

oil flow rate

required

in

the

vacuum pump.

In

addition

this

system

also

ensures

the

gassing

of

the

lubrication oil and therefore

the

low

noise

level

of

the

pump.

Gas

ballast When condensable vapours are being

pumped, gas

is

compressed beyond

its

saturated vapour pressure

in

the

"compression" phase and can

condense, impairing pump

performance.

The

gas ballast can

be

used

to

inject a

certain quantity of air (neutral or dry

COMPRESSION

gas)

into

the

last stage of

the

pump

during

the

"compression" phase

so

that

the

partial pressure of

the

pumped gas

is

less

than

its

saturated vapour pressure at

the

temperature of

the

pump.

Condensation

is

therefore impossible if

this

limit

is

not reached.

The

maximum'

admissible vapour pressure

is

obtained at pump inlet for

this

value.

At

the

end

of "compression",

the

pressure

in

the

exhaust chamber

is

greater than

atmospheric pressure.

An

anti-suckback device (valve + spring) prevents

the

gases

and oil

from

being drawn back into

the

inlet.

The

saturated vapour pressure of a body

is

higher when

the

system

is

hot than

when it

is

cold; therefore,

the

pump

must

reach operating temperature before

pumping condensable vapours.

&

'"

Using

the

the

pump

the

-

The

gas

ballast

control,

located

at

the

front

of

the

oil

case

cannot

be

used

to

rate.

-

When

the

gas

ballast

control

is

open,

the

pump

is

not

tight

when

stopped.

To

guarantee

this

tightness,

install

an

automatic

ballast.

Safety instructions concerning the installation and

operation

of

pumping

systems

Unpacking

When

you receive the equipment, unpack it carefully. Do not discard the

packaging until you have ensured that the pump

has

not been damaged

during transport. Otherwise, take the necessary measures with the transporting

company and,

if

necessary, notify

ALCATEL.

For all handling, only

use

the devices provided for this purpose (lifting rings,

handle, etc.).

The

pump

is

not supplied filled with oil.

The

oil

is

contained

in

separate

bottles. Similarly, it

is

recommended to drain the pump before redispatching

the equipment.

Storage

• if the pump

is

to be stored,

we

guarantee the reliability of our equipment

without particular storage precautions for up to 3 months (ambient

temperature between 41°F and 149°F or 5 and

6SOC).

•

For

storage periods

of

over 3 months,

we

recommend to fill the pump with

oil during storage.

For

this, fill the pump and

run

it at ultimate vacuum (inlet

orifice blocked) for approximately 1 hour in order to lubricate all

the

parts

of

the functional block (see

page

76).

Then,

stop

the

pump and store it with the inlet and exhaust orifices sealed:

clamping ring, centring ring, plug, etc.

The

shaft should be rotated

by

hand or

by

starting the pump every six months

following this storage procedure.

• After 6 months storage without oil, factors

such

as

temperature, degree of

humidity, salt air, etc. may cause the deterioration

of

the pump components,

particularly

the

hardening

of

O-rings and the "sticking"

of

lip seals on shafts

and the gumming

of

oil.

in

this state, a pump may have operational problems,

particularly oil leaks. Before any start-up (new pump

as

well

as

used), the

pump

must

be disassembled (see

page

91), and all the

seals

changed.

Note

1:

The

seal

kits

must

be stored with caution. Keep

them

away

from heat and

light (sunlight and ultraviolet light)

in

order

to

prevent the elostomers from

hardening (AFNOR standard

FD

T

46.022).

65

Installation and

start-up •

The

machines

must

be connected to an electrical installation

in

compliance

with decree

88-1056

dated 14th November

1988,

as

well as any local

electrical codes that apply.

•

It

is

important to isolate the machine from the power source before any

intervention on

the

equipment (for maintenance purposes).

• When switching off the power of equipment containing capacitors loaded

with over

60

VDC or

25

VAC, take precautions when accessing the connector

pins (single-phase motors, equipment with mains filter, frequency converter,

monitor, etc.).

• Vane roughing pumps

use

lubricants, it

is

recommended to request

information from the manufacturer on

the

safety data

sheets

concerning the

product used.

•

Our

pumps are tested

in

the factory with

ALCATEL

120

oil or Alcatel

119

for the USA (Alcatel

113

oil for the C2series).

It

is

recommended to

use

the

same oil during operation.

If

changing the type of oil, refer

to

the

chapter concerned for the procedure

and the type

of

lubricant required.

•

Our

pumps are designed to prevent any thermal risk for user safety.

However, specific operating conditions may generate temperatures which may

justify particular attention on the part of the user (outer

surfaces>

70°e).

pumping

procedure

-Valve off the pump from the

system

and increase the pump temperature,

30

minutes with gas ballast

(see

page

76).

-Start pumping and check

the

oil level:

•

the

level drops, oil

is

being lost;

•

the

level rises, condensates have been added to the oil.

-After pumping, regenerate the oil using gas ballast if it

is

cloudy

or

discoloured.

•

if

the level

is

too high, change

the

oil and regenerate.

-Change the oil

Operation of gas ballast

In

a pump stored with the same oil for a long time, condensed vapours may

contaminate the oil bath and affect performance.

This

is

also the case after

pumping vapours and when

the

oil appears cloudy or discolored through the

sight glass.

-

Run

the

pump, shutting it off from the

system

at the inlet

by

a valve or a

plug.

-Open the gas ballast and

allow

the pump

to

operate for

1/2

hour

to

1 hour, or longer

if

the oil remains cloudy.

This

operation accelerates the

temperature rise

of

the pump while eliminating residual vapours present

in

the oil bath.

To

pump with condensable products, it

is

necessary to operate with a hot

pump. For this, isolate the pump from the

system

and

allow

it

to

operate for

1/2

hour with the gas ballast open, or 1 hour (if possible) with the gas

ballast closed. When the oil bath

is

hot, the condensation

of

vapours

in

the pump

is

reduced

or

prevented.

The

pump's capacity to eliminate condensable vapours

is

their type,

the pump temperature and the quantity

of

air

introduced

by

the gas ballast.

Thus,

for high vapour levels

in

a

system,

the single-stage pump

is

more

suitable. However, when not pumping vapours,

its

ultimate pressure

is

higher.

Care should be taken

to

limit the inlet pressure

of

the pump to

its

maximum

admissible water vapor pressure with the pumped product.

This

is

obtained

by

reading the pump characteristic table for water vapour.

The

use

of

cold traps or condensers are recommended when large quantities

of

vapours are

to

be extracted. Excessively intense or prolonged pumping may

cause the products condensed

in

the trap to be evaporated a second time.

Choose an oil which facilitates

the

separation

of

pumped products which may

be condensed

in

the

oil bath (anti-emulsion oil for water-based compounds,

etc.)

(see

page 67).

Assembly

The

condensation

of

vapours at the pump exhaust

is

reduced if:

-the pump and oil temperature are high;

-the pressure at the exhaust

is

as

low

•

as possible (removal of the oil mist

eliminator...

);

-the condensates are collected

Exh.

separately from the oil bath and

do

not

block

the

exhaust duct.

For this:

-avoid using any vertical ducting which

promotes the condensation

of

products

and the return of

these

products to

the

pump.

-

use

a condensate collector;
