Oil carryover from Separator 1 to Separator 2 or Pump
5.1.29 Oil carryover can be detected during every run maintenance when cleaning the
separator 2 outlet to pump inlet and when spot checking separator 2. The
presence and severity of oil is an indication of carryover to the pump. While
slight oil can be tolerated, the pump was not designed to have oil circulating
through it. Oil carryover will reduce the life of the pump and can damage the
pump if severe.
5.1.30 Causes
5.1.30.1 Orifice orientation is not within tolerance and oil is radius blasting
inside separator instead of intended cyclone current. Check to make
sure the welded downtube on your separator cap has not been turner
or bent out of the acceptable angles in the figure below.
5.1.30.2 Separator temperatures are above 40F after system is equalized,
usually after 1 hour after initialing. The temperature set point on the
chiller has a direct relationship with separator temperature. Turn the
set point on the chiller down until separator temperature is below 40F.
5.1.30.3 Extreme cold temperatures in separators cause oil carryover as well. If
the separator is encased in a block of ice the temperature is more than
likely a tad too cold. Ensure that the chiller is on and correctly
functioning before beginning a run, water lines are correctly assembled
between the collector cup and the separator, and the water line quick
connects have disengaged the check valves.
