11. Oil Skimmer
The optional Oil Skimmer removes from the surface of the power washer's sump floating
oils, greases, sludge, fatty acids and other contaminants that cling to the wheel. These
contaminants cling to the rotating skimmer wheel, and are then scraped off into a
container by spring-loaded wiper blades. Water is not removed.
The skimmer provides these benefits:
·
Extension of cleaning-solution life
·
Better cleaning results
·
Reclamation of oil in many cases
11.1. Theory of Operation
The Oil Skimmer is mounted in a small box on the side of the power washer cabinet.
Refer to the following figure.
Skimmer Assembly : The skimmer is electrically connected to the washer by a
standard 120V 3-prong grounded plug. It is operated by a single-phase, 60-
cycle gear motor. The skimmer is lightweight and has only one moving part.
The skimmer's manual/off/auto switch is located on the washer's control panel.
Skimmer Function : The lower part of the skimmer wheel is submerged in the
solution. As the wheel rotates, it picks up oil and other clinging contaminants
from the surface of the solution. The contaminants are collected in the run-off
trough and directed to a suitable disposal container. The skimmer will remove
up to 1 1/2 gallons (5.7 liters) of contaminants each hour.
