A method for controlling content of mechanical impurities in the liquid, DEVICE FOR IMPLEMENTATION AND MONITORING SYSTEM Content of mechanical impurities in the liquid stream

摘要

FIELD: measurement equipment.;SUBSTANCE: group of inventions relates to control (monitoring) of content of mechanical impurities in flows of fluid media. The method to control content of mechanical impurities in working fluids, in particular, in liquid hydrocarbon fuel, consists in the fact that the flow of fuel is sent, maintaining the permanent flow, via a system of filtering partitions with serially reducing pore size, at the same time pressure is measured in front of each filtering partition, as well as pressure behind it, hydraulic resistance of the filtering partition in time is calculated on the basis of variation of pressure difference, then, using the produced data, they determine the degree of filtering partition clogging by comparison with available calibration data, showing variation of hydraulic resistance of the filtering partition depending on content of mechanical impurities, and on the basis of this data they determine quantity of mechanical impurities of certain size in fuel. Also the device and system for method realisation are described.;EFFECT: efficient control (monitoring) is achieved for availability of mechanical impurities in fuel, their weight quantity and particle distribution by size ranges during assessment of fuel treatment circuit efficiency.;7 cl, 2 dwg
