Filling
Lubricators may be filled either under no pressure or under pressure
- without shutting down equipment. To fill through the fill port, a
long spout oil can must be used. Slowly remove fill plug and insert
tip of spout to bottom of fill port recess or oil blow back will occur.
Fill to within 1/2" of top of bowl using correct oil. These lubricators
may also be fitted with Button Head Fill Fittings (SAA606C109-1)
to aid in refilling through the use of a bucket pump.
Lubricator Adjustment
The adjustment knob is factory set so that, when turned fully
clockwise, no oil is delivered to the venturi for atomization, and
equipment is not being lubricated. To initially adjust oil drip rate,
turn on the air, start flow and set knob to obtain the desired
drip rate, which is visible through the sight dome. After system
reaches normal operating temperature, fine tune the drip as
needed. As a start, one to two drops per minute is suggested,
correct lubrication being a matter of experience and demand.
Clockwise rotation of knob decreases oil feed rate. To check
lubrication, hold thumbnail or a mirror near the equipment
exhaust. A heavy film indicates over-lubrication and the drip rate
should be reduced by turning knob to a lower setting. After final
setting has been achieved, the knob may be removed to make
the adjustment mechanism tamper-resistant.
Cycling Applications
If the lubricator is to be used in a cycling application, the
conditions must be as follows:
• The lubricator must stay pressurized during On
AND
Off
cycles.
• On cycle time must be at least 15 seconds, and
• The flow rate during each on cycle must be at least 4 SCFM.
