Abstract
Contaminants of oil fillings of technological units using oil as a cooling, lubricating, insulating, or power medium, are removed by periodically applying a separating working cycle and a pressure working cycle in a vessel connected with the oil system of the technological unit, and returning the cleaned oil to the oil system of the unit. In the course of the separating working cycle, gaseous and liquid contaminants in the vessel are brought to boiling by under-pressure generated by a reversible pump; a gas-liquid cushion created thereby above the oil surface in the vessel is displaced from the vessel in the course of the following pressure working cycle, which is caused by the reverse action of the pump, while the cleaned oil is returned to the oil system of the technological unit. Both cycles are repeated as often as required to clean the oil to the desired degree.
