The oil skimmer is equipped with a frequency converter and a timer in order to adjust the capacity of the oil skimmer to the amount of sludge floating on the coolant.
During production, it takes about 5 – 10 min. until the thin layer of oil and particles floats on the surface of the coolant. It takes approx. 2 rounds of the oil collector tube to remove the floating particles with the magnets. During the start-up-period, the exact speed and the exact times were determined.
During production stop or during weekends, the coolant rests in the tank. Most of the tramp oil in the coolant floats on the surface when the coolant rests. During this time, the oil skimmer operates continuously in order to collect the floating tramp oil.
In addition, the oil skimmer was equipped with a sensor, which checks the operation of the oil collector tube. In case that the oil collector tube does not move, although the oil skimmer is working or in case that the oil collector tube has been destroyed mechanically an alarm is shown.
The switchboard of the oil skimmer can be connected with the central control system, so that the continuous supervision is possible.
