A
ir/Oil Minimal lubrication is a relatively new technology that has
been used successfully to substitute costly Oil Re-circulation and
non environmentally-sound Mist Systems.
It has provided excellent results both in terms of performance and
total system cost.
It is ideal for use on Bearings, High Speed Bearings, Gears and
also in certain circumstances on Guides. It is particularly suited to
Spindle Lubrication.
In the past, excessive oil has been used often only to ensure that
the ‘system is working’. This oil generates heat and has to be
collected away from the lubrication point.
Dropsa has taken the ‘minimal lubrication’ concept one step further
with the VIP4Air that can achieve ultra-low volume oil discharge
and at the same time provide electronic monitoring (using a custom
designed differential flow sensor integrated into the unit). This
allows true minimal lubrication by applying micro-amounts of
lubricants at more frequent intervals whilst giving positive feedback
that oil is correctly being injected and mixed into the air stream.
The VIP4Air System contains all components necessary to
achieve and monitor optimum minimal Air/Oil Lubrication.
PRODUCT FEATURES :
• 1 – 8 Lubrication Points each with independent monitoring
• 0.005 – 0.030 cm3(0.0003 – 0.0018 cu.in) of oil per discharge
(standard settings 7-15-30 mm3)(0.0004 – 0.0009 – 0.018 cu.in).
• Tamperproof adjustment ‘rings’ avoids end-user modifications.
• Integrated Differential Flow sensor gives positive feedback of
Air/Oil lubrication.
• Fully Electronic Controls = quick Set-up and interfacing to host.
• Integrated Mixing Air Pressure Transducer provides accurate
and quick setting of Air Pressure on the electronic display, as
well as providing alarms for blocked or broken lubrication lines
via high/low air pressure monitoring.
• Automated Priming Sequence for quick and easy installation.
• Integrated & Compact – Connections are internal to the unit

10.1 STARTING THE VIP4Tools PANEL
Before using the VIP4Tools panel, it is necessary to carry out some preliminary checks:
- check the integrity of the equipment
- check that the electrical and pneumatic connections have been effected correctly
- vent the residual air from the pump using the vent screw, located at the center of the
securing screws, until lubricant exits (retighten the vent screw without using excessive
force).
- to facilitate the venting, regulate the pumps to maximum flow and operate for some
cycles.
10.2 EXCLUDING LUBRICANT DELIVERY FROM AN INDIVIDUAL PUMP:
-Unscrew (anticlockwise) the red cap at the end of the pump to its stop, so completely blocking
off the delivery.
10.3 REGULATING LUBRICANT DELIVERY FLOW:
Use the red cap to determine the nominal flow of the individual pump.
- Completely unscrew the pump red regulating cap (0 mm³ flow) turn clockwise for 1.5 turns
(min. flow 5 mm³) after which every turn corresponds to an increase in flow of 5 mm³ until
reaching 30 mm³ at the 7th turn. (see table)
