Abstract

1. Способ определения содержания загрязнений в жидкости, текущей в трубопроводе, включающий отбор пробы жидкости, фильтрование пробы через фильтр и определение массы частиц загрязнений, осажденных на фильтре, отличающийся тем, что из текущей по трубопроводу жидкости проводят непрерывный отбор части жидкости в магистраль отбора через контрольный фильтр с измерением ее расхода, причем расход жидкости в магистрали отбора устанавливают с условием равенства скоростей жидкости в заборном элементе устройства отбора проб и жидкости в трубопроводе в месте установки устройства отбора проб, а содержание загрязнений в жидкости, текущей в трубопроводе, определяют по формуле ! , ! где m1 - масса частиц загрязнений в жидкости, прошедшей по трубопроводу; ! m2 - масса частиц загрязнений, осажденных на контрольном фильтре магистрали отбора проб; ! V0 - объем жидкости, прошедшей по трубопроводу; ! V2 - объем жидкости, прошедшей по магистрали отбора проб и контрольный фильтр. ! 2. Способ по п.1, отличающийся тем, что отфильтрованную на контрольном фильтре жидкость возвращают в трубопровод за местом отбора пробы.1. The method of determining the content of contaminants in the fluid flowing in the pipeline, including sampling the fluid, filtering the sample through the filter and determining the mass of particles of contaminants deposited on the filter, characterized in that a portion of the fluid is continuously taken from the fluid flowing through the pipeline to the sampling line through a control filter with a measurement of its flow rate, and the fluid flow rate in the sampling line is established with the condition that the fluid velocities in the intake element of the sampling device and fluid in the pipe water at the installation site sampling device, and the content of contaminants in a liquid flowing in a pipe is determined according to the formula! ! where m1 is the mass of particles of contaminants in the fluid passing through the pipeline; ! m2 is the mass of contaminant particles deposited on the control filter of the sampling line; ! V0 is the volume of fluid passing through the pipeline; ! V2 is the volume of fluid passing through the sampling line and a control filter. ! 2. The method according to claim 1, characterized in that the liquid filtered on the control filter is returned to the pipeline beyond the sampling point.
