ABSTRACT:
A flushing fluid recycling system used with an electroerosion machine which includes a regenerating unit, i.e. an ion-exchange column as deionizer, through which the used liquid medium, e.g. water, collected from an electroerosion zone is passed for regeneration and return to the electroerosion zone. A pump is periodically actuated to intermittently pass the liquid medium through the deionizing column with predetermined on-time and off-time regardless of whether the value of an electrical property, e.g. specific resistance of the fluid, determined by a sensing unit lies above a certain level. However, the ratio of the on-time to the off-time is altered depending on the particular value of the electrical property sensed.
