Recommended Maintenance Intervals
For latest available Recommended Maintenance Intervals, see ER-8.2 at
www.arielcorp.com.
Like all equipment, Ariel compressors do require maintenance. The frequency of mainte-
nance is dictated by the environment in which the compressor is placed, the loads the user
imposes on the compressor and the cleanliness of the gas.
First and foremost on the preventative maintenance list is the completion and compliance
with the Ariel Corporation Packagers Standard and Compressor Start Up Check List. All
items must be adhered to, both before and after start up.
The following is a guide only and, as stated above, may vary due to operating conditions.
The time intervals start from the start up date of the unit. If your oil supplier's recommended
oil service changes are more frequent than the Ariel recommendation, the supplier’s inter-
vals should be followed. Regular oil analysis is recommended. If problems develop, the oil
should be changed immediately and the cause of the problem determined and corrected.
A log book should be kept with each unit. Every maintenance item can be recorded with
exacting detail in order that records will be available for tracking maintenance cost per unit
and for trouble-shooting.
Operator logs should be reviewed by qualified personnel to determine trends in compressor
performance and/or maintenance.
Daily
1. Check frame oil pressure. It should be 50-60 PSIG (350-420 kPa) when at oper-
ating temperature. Compressor inlet oil temperature is 190°F (88°C) maximum.
2. Check frame oil level. Oil should be visible at approximately mid-level in the
sight glass when the compressor is running. If not, determine and correct the
problem. Do not overfill. Check oil makeup tank for sufficient oil supply.
3. Check lubricator block cycle movement indicator. Refer to information plate on
top of lubricator box for correct cycle time. Very dirty or wet gas may require a
more frequent cycle time than normal.
4. Check primary and secondary packing vents for blowing. If blowing, determine
cause and, if necessary, replace packing internal parts.
5. Check and correct any gas leaks.
6. Check and correct any oil leaks.
7. Check operating pressure and temperatures. If not normal, determine cause of
abnormality. It is recommended that a daily log of operating temperatures and
pressure be kept for reference.
