4.0 Installation

4.0  Installation

4.1  General

The air-cooled rotary compressor (SLS 34 / SLS 54)
and vacuum pumps (SLS 34 DV / SLS 54 DV) gene-
rate pressure or vacuum. For constant duty they are
designed for a maximum pressure of 2 bar or a
vacuum of 100 mbar (90 %).

A ventilator fastened on the end of the drive shaft
cools the compressor. The automatic lubricating
device is driven by the rotor shaft. For V-belt propul-
sion, the pulley wheel can be placed directly on the
end of the compressor shaft, provided the radial load
does not exceed 105 kg.

4.2  Assembly

4.2.1  Stationary operation

Assemble the compressor bolted on the foundation
panel in a vibration-free manner. A concrete founda-
tion is not required. Using bolts, fasten the foundation
panel on the surface.

Drive

When driven by an electric motor, the compressor
must be precisely aligned with the motor. Ensure cor-
rect spacing of the wobbler (about 3-5 mm). Switch
motor on briefly and check direction of rotation (see
arrow on fan cowl of the compressor).

Coupling

The coupling must be of a resilient design and must
not transmit any axial thrust from the motor to the
compressor.

4.2.2  Installation in vehicles

The installation site for the compressor must be easily
accessible and protected against falling objects. The
compressor must be firmly bolted on the chassis. Suf-
ficient space must be provided for connection of the
delivery and intake pipes.

4.3  Power transmission

The power is transmitted by an articulated shaft, a V-
belt or a coupling. 

4.3.1  Articulated shaft drive

The articulated shaft must be designed as a 

spline shaft and must be

balanced, as well as having the

smallest possible angle and must be as short as
possible.

The centre axes of the articulated shaft flanges must
be parallel to each other.

The articulated shaft attachment flange is to be
pushed on the drive shaft of the rotary compressor /
the vacuum pump.

The spline shaft section of the articulated shaft must
be bolted on the attachment flange of the compressor
shaft.

The resultant prop. shaft angle must not exceed 15° at

a speed of 1500 min

.

Do not fit the drive shaft the wrong way -
observe the marking!

DIAGRAM 4. Drive shaft

The machine must be adequately
earthed.

An earth bonding strap should be
securely fastened between the machine
body and a suitable point on the vehicle
frame.

Ensure that the machine and all ancil-
liaries are earthed inaccordance with
BS5958 Pt1: 1991; 'Control Of Undisira-
ble Static Electricity'.
