(54) СПОСОБ РЕГУЛИРОВАНИЯ ЦЕНТРОБЕЖНОГО КОМПРЕССОРА(54) METHOD FOR REGULATING CENTRIFUGAL COMPRESSOR
1one
Изобретение относитс к регулированию центробежных компрессоров.This invention relates to centrifugal compressor control.
Известен способ регулировани центробежного компрессора путем воздействи на исполнительные устройства по сигналам датчиков давлени и температуры газа, установленных на входе и выходе из компрессора I.There is a known method of controlling a centrifugal compressor by acting on actuators by signals from gas pressure and temperature sensors installed at the inlet and outlet of compressor I.
Однако этот способ не обеспечивает требуемой экономичности регулировани .However, this method does not provide the required economy of regulation.
Цель изобретени - повышение надежности .The purpose of the invention is to increase reliability.
Указанна цель достигаетс тем, что дополнительно измер ют текущую теплоемкость и массовый расход газа и по полученным сигна/там корректируют давление газа на входе и выходе из компрессора.This goal is achieved by additionally measuring the current heat capacity and mass flow rate of gas and, according to the received signal, corrects the gas pressure at the inlet and outlet of the compressor.
На чертеже представлена схема устройства , реализующего способ.The drawing shows a diagram of the device that implements the method.
Устройство содержит входной исполнительный механизм 1, выходной исполнительный механизм 2, датчики 3 и 4 давлени газа на входе и выходе из компрессора, датчики 5 и 6 температуры газа на входе и выходе первой ступени 7 компрессора, датчики 8 и 9 температуры газа на входе и выходе второй ступени 10 компрессора.The device contains an input actuator 1, an output actuator 2, sensors 3 and 4 of the gas pressure at the inlet and outlet of the compressor, sensors 5 and 6 of the gas temperature at the entrance and exit of the first stage 7 of the compressor, sensors 8 and 9 of the gas temperature at the entrance and exit second stage 10 compressor.
датчик 11 плотности газа и датчик 12 объемного расхода. Кроме того, на чертеже показаны вычислитель 13, теплообменник 14, технологическа установка 15 и конечный технологический аппарат 16. 5gas density sensor 11 and volumetric flow sensor 12. In addition, the drawing shows the calculator 13, the heat exchanger 14, the technological installation 15 and the final technological device 16. 5
Способ реализуетс в устройстве следующим образом.The method is implemented in the device as follows.
В вычислителе 13 по сигналам датчиков 5, 6, 8, 9 температуры, датчиков 11 и 12 Q плотности и объемного расхода газа, и по заданной зависимости теплоемкости газа от температуры, вычисл етс значение текущей теплоемкости и массового рас.хода газа, а затем определ етс значение текущей нагрузки компрессора по формулеIn the calculator 13, the signals of sensors 5, 6, 8, 9 of temperature, sensors 11 and 12 Q of density and volumetric gas flow rate, and for a given dependence of the heat capacity of the gas on temperature, calculate the value of the current heat capacity and mass flow rate of the gas flow, and then determine value of the current load of the compressor by the formula
15 где N - значение текущей нагрузки компрессора;15 where N is the value of the current compressor load;
3 - массовый расход газа; CpjO) - значение текущей теплоемкости 3 - mass flow rate of gas; CpjO) - the value of the current heat capacity
20 газа, вычисленное по заданной зависимости теплоемкости .от температуры газа на входе в i-тую степень компрессора с учетом концентрации и тепло20 gas, calculated from a given dependence of the heat capacity. From the gas temperature at the entrance to the i-th degree of the compressor, taking into account the concentration and heat
