WAY OF FLUID OPTIMAL WORKING PURITY MAINTAINING IN HYDRAULIC SYSTEMS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC F15B21/04 

FIELD: chemistry.

SUBSTANCE: method involves regulation of fluid treatment period and the period of stopping the cleaning process, and the cleaning period and the periods stop cleaning fluid is set in advance fluid contamination monitoring time in the hydraulic tank. After that, the sequence diagram of the block further purification in "work - pause" mode is set by a programmable time switch in accordance with the results of preliminary monitoring time cleaning performance and contamination period of time. The apparatus comprises a tank connected to the hydraulic unit further purification filter device comprising a pump, pump controller. In the pump control unit, the programmable timer is integrated, operable to regulate a continuous automatic repeat operating cycles purification unit and configured to replace operation cycle periods.

EFFECT: increase of reliability of maintaining the required level of cleanliness of the working fluid.
