Negative pressure measuring and adjustment

Measuring of the negative pressure

The negative pressure is measured with the pressure sensor underneath the ink pump,
when transferring ink into the buffer tank. This measured value is compared to a set point
value.

Adjustment of the negative pressure

Three cases can arise:

Measured value < Set point value

(weak suction and a risk of the gutter overflowing)

Air pumping is reactivated to increase the negative pressure in the buffer tank (suction
in buffer tank, backflow in condenser).

Measured value > Set point value

(strong suction but excess make up consumption)

Vacuum pumping (suction and backflow in buffer tank)

Measured value = Set point value

Air pumping to maintain negative pressure without exceeding the set point value.
Vacuum pumping if value exceeded.
