Description
Изобретение относитс к технике гид- р(авлического сопротивлени элементов гидравлических систем с жидким теплоносителем .The invention relates to the technique of hydr (avlicheskogo resistance of elements of hydraulic systems with a liquid coolant.
Известны способы определени гидравлических сопротивлений в современных теплотехнических системах (системах водного отоплени , дерных и других теплоэнергетических установках), заключак шиес в определении параметров эксплуатационных режимов путем расчета гидралических сопротивлений отдельных участков контура по Известным формулам p.j.There are known methods for determining hydraulic resistance in modern heat engineering systems (water heating systems, nuclear and other heat and power plants), which consist in determining the parameters of operating modes by calculating the hydraulic resistance of individual sections of the circuit using the well-known formulas p.j
Известные расчетные формулы .справедливы только дл : ограниченного, набора конфигураций участков и скоростей течени теплоносител . Дл выбора подход щей расчетной формулы дл участка необходимо знать вид течени в нем, который зависит в свою очередь от гидравлического сопротивлени контура в целом и условий теплоотвода .и теплоподвода в контуре.The known calculation formulas are valid only for: limited, set of configurations of sections and flow rates of the heat carrier. In order to choose a suitable calculation formula for a section, it is necessary to know the type of flow in it, which in turn depends on the hydraulic resistance of the circuit as a whole and the conditions of heat dissipation and heat supply in the circuit.
Поэтому процесс расчета гидравлического сопротивлени замкнутого контура Therefore, the process of calculating the hydraulic resistance of a closed loop
при малых расходах оказываетс чрезвычайно громоздким и может приводить к. неоднозначным результатам.at low costs, it is extremely cumbersome and can lead to ambiguous results.
Наиболее близким из известных вл етс способ определени гидравлического сопротивлени , заключающийс в создании заданного потока жидкости через макет, например, элементов силовых трасформаторов с последующим измерением перепада давлени 2.The closest known one is a method for determining hydraulic resistance, which consists in creating a predetermined flow of fluid through a prototype, for example, of elements of power transformers with subsequent measurement of pressure drop 2.
Использование известного способа дл определени гидравлического.сопротивлени замкнутого контура при малых расходах теплоносител неприемлемо из-за сложности измерени перепада давлени на каждом участке контура и необходимости учета гидростатического напора.Using a known method for determining the hydraulic resistance of a closed loop at low flow rates of the coolant is unacceptable due to the difficulty of measuring the pressure drop over each section of the circuit and the need to take hydrostatic pressure into account.
Пель изобретени - определение гидравлического сопротивлени замкнутого контура в диапазоне расходов естественной циркул ции жидкого теплоносител и упрощени процесса измерени .Pel of the invention is the determination of the hydraulic resistance of a closed loop in the range of flow rates of the natural circulation of the heat-transfer fluid and the simplification of the measurement process.
Достигаетс цель тем, что последовательно при двух различных мощност х подогрева измер ют скорость роста темThe goal is achieved by the fact that, at two different heating powers, the growth rate of
