Abstract
Способ определения ресурса фильтра, включающий пропускание загрязненной жидкости, измерение перепада давления и объема прошедшей жидкости, отличающийся тем, что, с целью повышения эксплуатационных возможностей способа, из падающей магистрали до фильтра отбирают пробу жидкости, пропускают ее через образец фильтрового материала, аналогичного материалу, которым оснащен фильтр, и в конце пропускания пробы измеряют температуру и расход жидкости через образец, с использованием измеренных значений температуры и расхода жидкости определяют перепад давления при течении через незагрязненный образец чистой жидкости с тем же расходом по формулеΔPov = v= αμhW+ βhρW ,где ΔPov = v- перепад давления при течении через материал чистой жидкости;μ - вязкость жидкости;ρ - плотность жидкости;W- скорость фильтрации;G - расход жидкости через образецF - площадь фильтрования;h - толщина материала;α и β - коэффициенты вязкостного и инерционного сопротивления соответственно, а ресурс фильтра определяют по формулегде V- ресурс фильтра;V- объем пробы жидкости, прошедшей через образец фильтрового материала;f- площадь фильтрования образца;F- площадь фильтрования фильтра;ΔPv = vи ΔPov = v- заданный (выбранный) предельный перепад давления на фильтре, определяющий ресурс фильтра, и перепад давления на незагрязненном фильтре при течении чистой жидкости с тем же расходом соответственно;ΔPv = v- измеренный перепад давления на образце фильтрового материала в конце пропускания пробы.The method of determining the filter life, which includes passing a polluted liquid, measuring the pressure drop and the volume of the transmitted liquid, characterized in that, in order to increase the operational capabilities of the method, a liquid sample is taken from the falling line to the filter, passing it through a sample of filter material similar to equipped with a filter, and at the end of the sample transmission measure the temperature and the flow rate of the liquid through the sample, using the measured values of temperature and flow rate determine the pressure drop when a pure liquid flows through an uncontaminated sample with the same flow rate using the formula ΔPov = v = αμhW + βhρW, where ΔPov = v is the pressure drop when flowing through a pure liquid material; μ is the fluid viscosity; ρ is the liquid density; W is the filtration rate; G is the fluid flow through the sample, F is the filtering area, h is the material thickness, α and β are the viscous and inertial resistance coefficients, respectively, and the filter life is determined by the formula V, the filter life, V is the volume of the sample that passed through the filter material sample, f - P sample filtering ground; F is the filtering area of the filter; ΔPv = vand ΔPov = v is the specified (selected) maximum pressure drop across the filter, which determines the filter life, and the pressure drop on an unpolluted filter when the flow of pure liquid with the same flow rate is respectively; ΔPv = v - the measured pressure drop across the sample of filter material at the end of sample transmission.
