How to configure the origin value of rider ring wear calculation?Download PDF 1

After each replacement of the piston rider rings or adjustment/ replacement of sensor the rider ring wear monitor has to be reset to zero.  For this purpose the PROGNOST®-NT VISU software provides a separate dialog under “Tools – Rider Ring Wear Settings”.

Rider Ring Wear

  1. Sensor
  2. Input support for executed activities (for example, the installation of a new rider ring)
  3. Changeable parameters
  4. Trend of the rider ring wear
  5. Trend of the single value = average value of rod position

New rider rings have been installed

The following steps are required if you have installed new rider rings:

  • Check value of wear potential.
  • If the wear potential changes, the first and second warning threshold must be adjusted.
  • Position cursor inside the trend window (position should be selected so that it is placed within a time period of 2 hours to a maximum of 2 days following the start of the machine).
  • Select Apply.
  • Select Save.

Residual wear potential measured

The following steps are required once you have measured the residual potential of the rider rings:

  • Enter residual potential value.
  • Position cursor inside trend window (position must be selected so that cursor falls between 2 hours and a maximum of 2 days following the start of the machine).
  • Select Apply.
  • Select Save.

Just changed the sensor position

The following steps are required if you have changed the sensor position:

  • Position of 1st cursor inside the trend window (position should be selected so that it is placed within a time period of 2 hours to a maximum of 2 days following the start of the machine).
  • Position of 2nd cursor inside the trend window (position should be selected so that it is placed within a time period of 2 hours to a maximum of 2 days following the start of the machine). Use the button to change between the 1st and 2nd cursor.
  • Select Apply.
  • Select Save.
