Preface

Congratulations on your purchase of the Busch compressor. With
watchful observation of the field’s requirements, innovation and steady
development Busch delivers modern vacuum and pressure solutions
worldwide.

These operating instructions contain information for

–

product description,

–

safety,

–

transport,

–

storage,

–

installation and commissioning,

–

maintenance,

–

overhaul,

–

troubleshooting and

–

spare parts

of the compressor.

For the purpose of these instructions, “handling” the compressor
means the transport, storage, installation, commissioning, influence on
operating conditions, maintenance, troubleshooting and overhaul of
the compressor.

Prior to handling the compressor these operating instructions shall be
read and understood. If anything remains to be clarified please con­tact your Busch representative!

Keep these operating instructions and, if applicable, other pertinent
operating instructions available on site.

Product Description

Use

The compressor is intended for

–

the compression

of

– air and other dry, non-aggressive, non-toxic and non-explosive

gases

Conveying media with a lower or higher density than air leads to an in­creased thermal and/or mechanical load on the compressor and is per­missible only after prior consultation with Busch.

Max. allowed temperature of the inlet gas: 40 °C

Standard-version:

The gas shall be free from vapours that would condensate under
the temperature and pressure conditions inside the compressor.

Version “Aqua”:

The compressor features the corrosion protection coating CPC and
is capable of conveying water vapour (Ú page 7: Conveying
Condensable Vapours). Conveyance of other vapours shall be
agreed upon with Busch. Conveyance of water or other liquids in
liquid phase increases the power consumption and shall therefore
be avoided (risk of drive overload).

The compressor is intended for the placement in a non-potentially ex­plosive environment.

The compressor is thermally suitable for continuous operation
(100 percent duty).

Max. permissible number of startings per hour: 12

The maximum allowed pressure on the pressure connection (i) is

0.8 ... 2.0 barg (the nameplate of the compressor indicates the valid
pressure). By means of process control and/or pressure relief valves it
must be made sure that the maximum allowed pressure will not be
exceeded.

Principle of Operation

The compressor works on the claw principle.

The components are dimensioned such, that on the one hand there is
never contact between the two claws or between a claw and the cylin

-

der, on the other hand the gaps are small enough to keep the
clearance loss between the chambers low.

In order to avoid the suction of solids, the compressor is equipped with
a screen (715) in the gas inlet.

In order to avoid reverse rotation after switching off, the compressor is
equipped with a non-return valve (714).

The compressor compresses the inlet gas absolutely oil-free. A lubrica­tion of the pump chamber is neither necessary nor allowed.

Cooling

The compressor is cooled by

–

radiation of heat from the surface of the compressor

–

the air flow from the fan wheel of the drive motor

–

the process gas

–

the air flow from the fan wheel mounted opposite the drive motor,
driven by a separate motor (e)

Start Controls

The compressor comes without start controls. The control of the
compressor is to be provided in the course of installation.

state-of-the-art methods. Nevertheless, residual risks may remain.
These operating instructions highlight potential hazards where appro

­priate. Safety notes are tagged with one of the keywords DANGER,
WARNING and CAUTION as follows:

DANGER_a

Disregard of this safety note will always lead to accidents with fa

-

tal or serious injuries.

WARNING_a

Disregard of this safety note may lead to accidents with fatal or se­rious injuries.

CAUTION_a

Disregard of this safety note may lead to accidents with minor inju­ries or property damage.

Risk of damage to the hearing.

Persons staying in the vicinity of a non noise insulated compressor
over extended periods shall wear ear protection.

Transport

Transport in Packaging

Packed on a pallet the compressor is to be transported with a forklift.

Transport without Packaging

In case the compressor is packed in a cardboard box with inflated
cushions:

◆ Remove the inflated cushions from the box

In case the compressor is in a cardboard box cushioned with rolled cor­rugated cardboard:

◆ Remove the corrugated cardboard from the box

In case the compressor is laid in foam:

◆ Remove the foam

In case the compressor is bolted to a pallet or a base plate:

◆ Remove the bolting between the compressor and the pal­let/base plate

In case the compressor is fastened to the pallet by means of tightening
straps:

◆

Remove the tightening straps

CAUTION_af

Do not walk, stand or work under suspended loads.

●

Attach lifting gear securely to the eyelets on the base frame

●

Attach another belt/rope as a protection against overturning to a
suitable point (eyebolt, drive motor flange etc.)

●

Attach the lifting gear to a crane hook with safety latch

●

Loosely hang the additional belt/rope into the crane hook

●

Lift the compressor with a crane

In case the compressor was bolted to a pallet or a base plate:

◆

Storage

Short-term Storage

●

Make sure that the gas inlet and the pressure connection are
closed (leave the provided plugs in)

●

Store the compressor

–

if possible in original packaging,

–

indoors,

–

dry,

–

dust free and

–

vibration free

Conservation

In case of adverse ambient conditions (e.g. aggressive atmosphere, fre­quent temperature changes) conserve the compressor immediately. In
case of favourable ambient conditions conserve the compressor if a
storage of more than 3 months is scheduled.

● Make sure that all ports are firmly closed; seal all ports that are not
sealed with PTFE-tape, gaskets or o-rings with adhesive tape

Note: VCI stands for “volatile corrosion inhibitor”. VCI-products (film,
paper, cardboard, foam) evaporate a substance that condenses in mo­lecular thickness on the packed good and by its electro-chemical prop­erties effectively suppresses corrosion on metallic surfaces. However,
VCI-products may attack the surfaces of plastics and elastomers. Seek
advice from your local packaging dealer! Busch uses CORTEC
VCI 126 R film for the overseas packaging of large equipment.

● Wrap the compressor in VCI film

● Store the compressor

–

if possible in original packing,

–

indoors,

–

dry,

–

dust free and

–

vibration free.

For commissioning after conservation:

● Make sure that all remains of adhesive tape are removed from the
ports

● Commission the compressor as described in the chapter Installation
and Commissioning (Ú page 4)

Gas Inlet

CAUTION_a

Intruding foreign objects or liquids can destroy the compressor.

In case the inlet gas can contain dust or other foreign solid particles:

◆ Make sure that a suitable filter (5 micron or less) is installed

upstream the compressor

The following guidelines for the suction line do not apply, if the air to
be compressed is taken in right at the compressor.

●

Make sure that the suction line fits to the gas inlet (b) of the
compressor

●

Make sure that the gas will be sucked through a vacuum-tight
flexible hose or a pipe

In case of using a pipe:

◆

Make sure that the pipe will cause no stress on the
compressor’s connection, if necessary use an expansion joint

●

Make sure that the line size of the suction line over the entire
length is at least as large as the gas inlet (b) of the compressor

In case the length of the suction line exceeds 2 m it is prudent to use
larger line sizes in order to avoid a loss of efficiency and an overload of
the compressor. Seek advice from your Busch representative!

Version “Aqua”, if very humid process gases and/or adverse operating
cycles bear the risk, that condensates remain in the compressor:

◆

Provide a shut-off valve, a drip-leg and a drain cock in the suc

­tion line, so that condensates can be drained from the suction
line

◆

Provide a valve for the unthrottled suction of ambient air (am

­bient air valve) between the shut-off valve and the compressor
(in order to dry the compressor after process end).

●

Make sure that the suction line does not contain foreign objects,
e.g. welding scales

Pressure Connection

● Make sure that the pressure line fits to the pressure connection (i)
of the compressor

● Make sure that the pressure connection is connected to a pres­sure-tight flexible hose or a pipe

● Make sure that the pressure line is designed for 2 barg and 250 °C

In case of using a pipe:

◆ Make sure that the pipe will cause no stress on the

compressor’s connection, if necessary use an expansion joint

● Make sure that the line size of the pressure line over the entire
length is at least as large as the pressure connection (i) of the
compressor

In case the length of the pressure line exceeds 2 m it is prudent to use
larger line sizes in order to avoid a loss of efficiency and an overload of
the compressor. Seek advice from your Busch representative!

● Make sure that the pressure line either slopes away from the
compressor or provide a liquid separator or a drip leg with a drain
cock, so that no liquids can back up into the compressor

Conveying Condensable Vapours

Version “Aqua”:

CAUTION_a

Due to the corrosion protection coating CPC the compressor is ca­pable of conveying water vapour.

Very humid process gases and/or adverse operating cycles can lead
to residual condensates, though, which cause corrosion.

If this is the case, it is necessary to counteract residual condensates
by warming up the compressor, conveyance of ambient air after
process end and regular draining of the anti-pulsation chamber.

◆ Close the shut-off valve in the suction line

◆ Warm up the compressor for approx. 10 minutes

At process start:

◆ Open the shut-off valve in the suction line

At the process end:

◆ Close the shut-off valve in the suction line

◆ Open the ambient air valve

◆

Operate the compressor for another approx. 10 minutes

◆

Close the ambient air valve

CAUTION_a

During operation of the compressor the anti-pulsation chamber is
under pressure.

Risk of injury when the condensate drain cock is opened!

Drain condensate only when the compressor is shut down and the
pressure connection (i) is vented to atmospheric pressure.

◆

Regularly drain condensate from the anti-pulsation chamber

Maintenance

DANGER_age32

In case the compressor conveyed gas that was contaminated with
foreign materials which are dangerous to health, harmful material
can reside in filters.

Danger to health during inspection, cleaning or replacement of fil

-

ters.

Danger to the environment.

Personal protective equipment must be worn during the handling
of contaminated filters.

Contaminated filters are special waste and must be disposed of
separately in compliance with applicable regulations.

CAUTION_ac

During operation the surface of the compressor may reach temperatures of more than 70 °C.

Risk of burns!

Let the compressor cool down prior to a required contact or wear heat protection gloves.

Problem Possible Cause Remedy

The compressor does not reach the usual pres­sure

The drive motor draws a too high current
(compare with initial value after commission­ing)

Filling the system takes too long
Building up pressure in the system takes too

long

The pressure system or pressure line is not
leak-tight

Check the hose or pipe connections for possi­ble leak

The pressure relief valve/regulating system is
misadjusted or defective

Adjust, repair or replace, respectively

The screen (715) in the gas inlet (b) is partially
clogged

Clean the screen (715)
If cleaning is required too frequently install a

filter upstream

In case a filter (b) is installed on the gas inlet
(b):

The filter (b) on the gas inlet (b) is partially
clogged

Clean or replace the inlet air filter (b), respec­tively

Partial clogging in the suction, discharge or
pressure line

Remove the clogging

Long suction, discharge or pressure line with
too small diameter

Use larger diameter

The valve disk of the inlet non-return valve is
stuck in closed or partially open position

Disassemble the inlet, clean the screen (715)
and the valve (714) as required and reassem­ble

Internal parts are worn or damaged Repair the compressor (Busch service)

The compressor does not start The drive motor is not supplied with the cor-

rect voltage or is overloaded

Supply the drive motor with the correct volt­age

The drive motor starter overload protection is
too small or trip level is too low

Compare the trip level of the drive motor
starter overload protection with the data on
the nameplate, correct if necessary

In case of high ambient temperature: set the
trip level of the drive motor starter overload
protection 5 percent above the nominal drive
motor current

One of the fuses has blown Check the fuses

The connection cable is too small or too long
causing a voltage drop at the compressor

Use sufficiently dimensioned cable
