General
The normal routine of running the machine is very simple. If it is carried out strictly at all times, many years of trouble free service can
be expected.
We emphasise three points of paramount importance-
1. Filtration of incoming air of gas
2. Lubrication
3. Temperature monitoring
It is essential that the compressor/booster is installed, commissioned and maintained correctly. To assist with this an
installation/commissioning check sheet, and a sample logbook record sheet is found at the back of this manual. If the operator can
enter daily/weekly readings into the logbook, with regular logbook readings along with the check sheet completed on installation can
then show whether the machine is performing as it did originally.
Operating Principle
Centrifugal pumps, work as their name suggests by centrifugal force driving outwards from the centre of rotation. They provide a
constant, low-pulsation supply of air or gas.
The machines have an impeller rotating inside a volute casing. The air/gas enters at the eye (centre) of the impeller, and is thrown out
to the edge of the casing by centrifugal force as the impeller rotates (fig 1) and is discharged through the machine outlet.
The impeller has a number of curved vanes fitted to either one or fitted between two side plates (fig 2) to generate the centrifugal
force when the impeller is rotated at high speed.
Some boosters has multi-stages, following the same principle through each stage, the main advantage of multi-stage pumps is that
they are able to achieve higher delivery pressures, which allows greater flexibility in variations of flow and pressures
The machine can only be run in one direction, which is indicated by an arrow on the casing. The direction of rotation must not be
reversed.
