Pressure set point
7.9.1 Automatic operation
For the automatic operation it is necessary to set a pressure set point. The pressure set point is a
control variable, which specifies the speed of the eccentric screw pump, so that a constant pressure
prevails in the screen housing of the separator.
The pressure set point regulates the inlet pressure and the feed flow, this way the separator is supplied
with only as much material as is needed. Due to the precisely controlled feed rate no overflow and no
ventilation for the overflow is needed.
The optimal system pressure varies depending on the medium and can be individually adjusted with
the potentiometer for the automatic operation (min. 0, 1 bar, - max.0, 3 bar).
7.9.2 Adjusting the pressure set point
The adjustment of the pressure set point is done by a potentiometer on the front of the control panel.
Classification of the scale:
potentiometer on position 0 = 0,1 bar
potentiometer on position 10 = 0,3 bar
7.9.3 Shutdown of the plant at excess pressure
On the one hand the built-in disconnection with overpressure serves for the protection
of the pressure sensor and the system and on the other hand the overpressure discon-
nection prevents the separator from a
“breakthrough”. The „disconnection with over-
pressure
“ is only active during automatic operation. In manual operation the operator
must make sure that the overflow can run off freely, the air pipe is screwed on and that
the
1 ½” ball valve in inlet T- piece is opened to prevent an increase of pressure in the
inlet. If the pressure in the inlet rises too high, it can cause damage to the system. The
shut-down pressure which is preset in the sensor is set in the factory and cannot be
changed. The maximum pressure in the sensor is set higher than the maximum working
pressure(0,3bar). The sensor is adjusted in order to switch the system off in case the
maximum pressure is exceeded and the fault lamp on the electrical cabinet and on the
pressure sensor lights up. In order to start the system again, the pressure must be re-
leased from the inlet pipes (red light on the pressure sensor goes out).
