Micro-Mist Lubricators (Figure 1)
Description
These micro-mist lubricators are designed to deliver an atomized oil mist to air
operated tools, motors, and other pneumatic equipment. Units are equipped
with full-view sight glass for visual indication of oil drop rate, needle valve feed
adjustment to regulate oil drop rate, and a venturi bypass disc to compensate
for changes in air flow demands.
Installation of Lubricator
1.
Lubricator should be installed with reasonable accessibility for service
whenever possible - repair service kits are available. Keep pipe and tubing
lengths to a minimum with inside clean and free of dirt and chips. Pipe
joint compounds should be used sparingly and applied only to the male
pipe – never into the female port. Do not use PTFE tape to seal pipe joints
- pieces have a tendency to break off and lodge inside the unit, possibly
causing malfunction.
2.
Install lubricator so that air flow is in the direction of arrow on body.
3.
Installation should be upstream from, and as close as possible, to the
device it is to lubricate (valve, cylinder, tool, etc.). Whenever possible,
avoid locations that require air-borne oil to move in an upward direction to
reach the device to be lubricated.
4.
The installation of an individual lubricator for each air consuming device
provides best assurances of proper lubrication.
5.
In new installations, it is good practice to “wet down” the inside diameter of
piping and/hose with oil before making final connections. Although your
lubricator delivers oil to the line, pre-coating the inside diameter with oil
helps insure that proper amounts of oil are delivered to the point
of application.
Operation & Service of Lubricator
! Warning: Before filling, inlet pressure must be eliminated and
then de-pressurize system pressure.
1.
FILLING - After de-pressurizing system, remove fill plug or bowl to refill
lubricator. Fill bowl to fill line indicated on the bowl with oil of 150 to 200
SSU at 100°F viscosity - same as SAE No. 10 (petroleum based hydraulic
oils or spindle oils are good examples). DO NOT USE OILS WITH TACKY
ADDITIVES, COMPOUND OILS CONTAINING SOLVENTS, GRAPHITE,
SOAPS OR DETERGENTS. (Automotive oils generally contain detergents
and are not recommended.
2.
Replace the fill plug or bowl and seat firmly. Excessive torque is not
necessary. The lubricator is now ready for setting.
3.
OIL DELIVERY ADJUSTMENT - To adjust oil delivery, turn the adjusting
needle on top of the lubricator.
Leaner - Clockwise
Richer - Counterclockwise
By counting the number of drops per minute in the sight dome, you can adjust
lubricator to your required setting. Approximately 3% of the droplets visible in
the sight dome go downstream; adjust drip rate accordingly. Consult oil delivery
conversion chart (see below).
Generally, one drop per minute downstream for every 10-15 SCFM flow is
satisfactory. 25 drops per minute equals one ounce per hour - volume of oil
passing through the sight dome.
NOTE: This is a constant density type lubricator which delivers a constant
ratio of oil to air flow. Therefore, if air flow increases or decreases, oil
delivery will be effected proportionately. ONLY IF DIFFERENT RATIO
IS DESIRED NEED YOUR NEEDLE VALVE SETTING BE CHANGED
AFTER YOUR INITIAL SETTING.

WARNING
To avoid unpredictable system behavior that can cause personal injury
and property damage:
• Disconnect electrical supply (when necessary) before installation,
servicing, or conversion.
• Disconnect air supply and depressurize all air lines connected to
this product before installation, servicing, or conversion.
• Operate within the manufacturer’s specified pressure, temperature,
and other conditions listed in these instructions.
• Medium must be moisture-free if ambient temperature is below
freezing.
• Service according to procedures listed in these instructions.
• Installation, service, and conversion of these products must be
performed by knowledgeable personnel who understand how
pneumatic products are to be applied.
• After installation, servicing, or conversion, air and electrical
supplies (when necessary) should be connected and the product
tested for proper function and leakage. If audible leakage is present,
or the product does not operate properly, do not put into use.
• Warnings and specifications on the product should not be covered
by paint, etc. If masking is not possible, contact your local
representative for replacement labels.
