8.1 TESTING

All the Battioni Pagani rotary blades vacuum pumps are tested before delivery at our factory.
®
To carry out testing of the rotary blades vacuum pump verify the previous steps, possibly using a
workbench.
Ensure that the shaft of the power take-off (PTO) turns freely and that the direction of rotation is
the same as that indicated by the arrow.
In case of verification of operation of the rotary blades vacuum pump without connection to the intake/discharge
pipes, there is a danger of severing for the operators due to access to the inside of the discharge elbow. There is
also danger under the same conditions of the intake of foreign objects inside the machine.
Check that the handle position is correct and that the rotary blades vacuum pump is intaking or compressing.

8.2 RUNNING IN

The running in period foreseen for a rotary blades pump is of 30 of effective working. During that period the working parameters
must be reduced of 20%

Pressure: the maximum permitted pressure is 2,5 absolute bar (1.5 relative bar).
In order to avoid exceeding this value or to obtain a lower max pressure, an over-
pressure valve, "C", must be applied that is of a size capable of discharging the
excess air delivery. Working pressure 2 bar absolute (1 bar relative).
Vacuum: too high a vacuum can cause ovality and undulation of the body or
breaking of the blades. It is therefore advisable to use a vacuum regulator valve,
"D". These valves may be fitted on the manifold cover or on manifold of the
Rotary blades vacuum pump. Vacuum working degree is of –0,80 bar.

8 - TESTING AND RUNNING IN

ATTENTION: The system must ALWAYS be equipped
with a vacuum regulating valve (calibrated at -0.80
bar) and overpressure valve (calibrated at 1 bar).
Adjustment of the valves must be performed by the
customer at the testing phase.
The regulation of the valves is done by acting on the
throttle placed on the valve same (overpressure valve) or
action on nut and locknut (vacuum adjustment valve).
