8. PRESSURE GAUGES
We recommend that pressure gauges are checked from
time to time. For this purpose we have developed a special
test pressure gauge with an adaptor which immediately re
cognizes any deviations in readings.
See High Pressure Accessories Catalogue no.
8550/7.92.
Slight deviations during operation are normal and can be ig
nored. Excessive inaccuracy will require the pressure gauge
to be replaced.
9. VALVES
9.1. GENERAL INSTRUCTIONS FOR CHANGING
THE VALVES
Always replace valves as a complete set.
Carefully clean dirty valves. Never use a sharp tool for
this purpose. Soak the valves in diesel oil or petroleum
and clean with soft brush.
Lubricate valves before installing with Weicon AS 040,
order no. N19753, or equivalent.
Check individual components for excessive wear. If the
valve seat and valve disks are dented, replace the valves.
Valve head screws must be tightened with a torque
wrench (see tightening torque values chapter D.17.1.).
Check the valve space in the valve heads for dirt and
clean, if necessary.
Use only satisfactory gaskets and O-rings on reas
sembly.
Observe the correct sequence when fitting together
again.
After finishing all maintenance work on the valves,
turn the compressor manually using the flywheel and
check whether all items have been correctly installed.
30 minutes after restarting the compressor unit stop
unit, let it cool down to ambient temperature and
retighten valve studs and cap nuts. Otherwise valves
could work loose due to setting of the gaskets.
9.2. CHANGING THE VALVES
9.3. VALVE CHANGE
Changing the valves should be performed by trained per
sonnel, only.
Valve change is described in the workshop manual which
is available through the BAUER technical service.
10. AUTOMATIC CONDENSATE DRAIN
10.1. GENERAL
Due care must be taken to ensure that any oil which may
be drained with the condensate will not pollute the envir
onment. For example, the drain pipe can be directed into
a collecting vessel or into drain facilities incorporating oil
separators.
Dispose of the condensate according to
local regulations!
10.2. MAINTENANCE
The condensate drain valves for the intermediate separat
ors and for the oil and water separator are provided with
manual drain valves to check correct operation of the auto
matic system.
The automatic condensate drain system must be serviced
as follows:
- Open all manual drain valves on the separators one after
the other, once a week.
This must be carried out immediately after the automatic
system has drained the condensate. Observe the drainage
of condensate when opening the manual drain valves. If the
system drains a lot of condensate this is a sign that the sys
tem or the corresponding condensate drain valves are not
working properly. Find the fault and remedy accordingly. If
hardly any condensate emerges, the automatic system is
operating properly. For fault correction, see section D-16.
“Trouble-shooting”.
