5 OPERATION AND ROUTINE MAINTENANCE
5.1 OPERATION AND GENERAL MAINTENANCE
The commissioning procedure (Section 4) should be used:
–
a) For the first commissioning run;
b) Following overhaul;
c) After standing idle for an extended period.
External cleanliness of the compressor pipework and jointing is imperative in order that any leakages
may be readily detected. Monitor and record stage pressures and temperatures in order to give
advanced warning of any malfunction. Ambient conditions, especially temperatures, will vary readings
but they are usually within plus or minus 4%.
Marking the pressure gauge glass at the normal running pressure will allow easy comparisons of
pressure to be made.
5.2 STARTING UP
Ensure operator is fully conversant with controls and safety devices.
Check oil level in crankcase and top up if necessary, using recommended oil until sight glass is up to
high level mark.
Set stop valves in control pipework correctly.
Ensure trip circuits, if fitted, are correctly set.
Check V belts are in good condition and correctly tensioned. Check APP011.
Check that compressor and ancillary equipment are clear of all loose equipment and tools.
Ensure that there is adequate water in the cooling system (radiator sets) or supply from the mains.
Manually operate suction unloaders if receiver pressure is unavailable to achieve this.
Operate main control or motor starting gear.
As soon as Diaphragm Drain Valves (DDV’s) are actuated to load machine, release suction unloaders
if previously manually operated.
5.3 RUNNING ON LOAD
Set automatic timer (when fitted) to vent diaphragm drain valves every 30 minutes for 5 seconds
duration, or more frequently if high humidity prevails. Contact Gardner Denver Ltd for more details.
Monitor gauges for normal pressures and temperatures.
Check water temperature rise 10°C to 12°C across machine and adjust to suit.
Observe compressor is functioning correctly without undue vibration or noise.
