Device for removing moisture from oil

Abstract

A device in which moisture-adsorbing material that adsorbs moisture dissolved in oil and the electrical resistance of which decreases in accordance with the amount of moisture adsorbed, is immersed in circulating oil supplied to machinery and is connected to a sensor that outputs a signal when the electrical resistance of the material falls below a given preset value. This moisture-adsorbing material absorbs moisture not yet dissociated from the oil, and removes the moisture from the oil, preventing deterioration of the oil. Moreover, because the sensor electrically detects the decline in the adsorptive strength of the moisture-absorbing material as the amount of moisture adsorbed increases, upon depletion of this adsorptive capability the material can be rapidly replaced, permitting the moisture content of the oil to be held below a given value.
