5.6 Nozzle assembly regulation – fixed
brake plate
Nozzle assembly regulation is used to achieve the most favourable pressure
drop possible across the brake plate.
Nozzle assembly regulation should be adjusted for Stage 2 output
Adjustment
Adjust to the desired position on the scale (A) using the set screw (B)
(turning anti-clockwise reduces the pressure drop and moves the brake plate
outwards).
If pulsation occurs, the pressure drop across the brake plate can be alte-red
until pulsation stops.
5.7 Nozzle assembly regulation –
adjustable brake plate
Nozzle assembly regulation is used to achieve the most favourable pressure
drop possible across the brake plate for each output stage.
Two nozzles
Nozzle assembly regulation adjusts the position of the brake plate between
Stage 1 and Stage 2 by means of a hydraulic piston.
Three nozzles
Nozzle assembly regulation adjusts the position of the brake plate between
Stage 2 and Stage 3 by means of a hydraulic piston.
Low load
The low load adjustment takes place by changing the guide rail’s mounting
to the hydraulic piston.
This takes place using a locking screw located through an oval hole. In the
default setting, the value that is read in the table (3,4 3,5) is used for the
setting values for the chosen power for step 2. During operation, the insert is
adjusted in order to achieve the best function.
Undo the locking screw (C).
Set the desired position on the scale (A) by pushing the disc in the desired
position.
Tighten the screw (C).
High load
Adjust to the desired position on the scale (A) using the set screw (D)
(turning anti-clockwise reduces the pressure drop and moves the brake plate
outwards). If pulsation occurs, the pressure drop across the brake plate can
be alte-red until pulsation stops.
