・If the machine operation is irregular in a day, calculate the oil amount (V cm
3
/h) by dividing with
actual operated time (h, hour).
(3) Estimated calculation of oil consumption from the number of oil drips in the sight-dome.
MC9 oil shots pump supplies oil drop to venturi-nozzle by 0.05 cm
3
per shot through the drip
tube in the sight-dome. If 10% of the supplied oil amount (atomized oil percentage would
depend on kind of oils, and operating pressure) is transferred to lubrication:
Oil consumption for 1minute is as following:
N (＝Number of oil drips) × 0.05 × 0.1 ＝ 0.005 × N(cm
3
)
(4) Generation of Micron-Fog by Micron-Lub unit will be confirmed by followings.
Put glass plate or mirror in front of the Fog-Nozzle for about 5 minutes.
If oil appeared on the surface of the glass plate or mirror, lubrication system works
satisfactorily.
If there is an extra port of nozzle branched from the main manifold, use this port for checking.
If an extra nozzle port is branched from the main manifold line, use this port for checking.
7-8. Oil Replenishment
・Oil replenishment is possible without stopping the supply air
and the supply electricity.
・Oil replenishment should be done when oil surface moves to
the OIL FILL LEVEL of the reservoir or when alarming signal
is issued through oil level switch.
Oil amount remained in the reservoir is enough to ensure
sufficient time for oil replenishment on this time. Replenish
oil without haste.
・Open the filler ports after checking around the filler port is
clean, and replenish the oil slowly. After oil replenishment,
close the filler port cap tightly.
・Refill clean specified oil
・Pour oil little by little for the refilling during the operation in order to avoid blow
off of oil by weak return air.
・Do not use non-specified oil. The machine could be damaged
7-9. Operation of Warning equipment
・If operating pressure decrease, manifold pressure failure, or oil amount decrease occurred, the
warning signal will be issued. Output equipment such as lamp and buzzer, if these were installed,
would be actuated by the warning signal.
・When the warning has issued, check each section according to each warning.
・Operating pressure switch: PS switches when operating pressure becomes under 0.1MPa.
