Description
ни , соответственно, устанавливаемые на диагностируемый узел гидронрИБОда. На выходе преобразователей 1 и 2 температуры и расхода установлены измерительные приборы 4 и 5. С первичным преобразователем 3 давлени св заны прибор 6 дл измерени пульсаций давлени через дифференцирующую цепочку 7 и прибор 8 дл измерени средней величины давлени через интегрирующую цепочку 9. Устройство 10 дл определени частоты импульсов св зано с первичным преобразователем 3 через формирователь импульсов 11. К первичному преобразователю 3 подключен также электронный осциллоскоп 12 дл анализа формы кривой пульсаций давлени .nor, respectively, installed on the diagnosed node of the hydronibr. At the output of the temperature and flow transducers 1 and 2, measuring devices 4 and 5 are installed. The pressure transducer 3 is connected to a device 6 for measuring pressure pulsations through a differentiating chain 7 and a device 8 for measuring the average pressure through an integrating chain 9. Device 10 for determining the pulse frequencies are connected to the primary transducer 3 through the pulse shaper 11. An electronic oscilloscope 12 is also connected to the primary transducer 3 to analyze the shape of the pressure pulsation curve.
Диагностирование производитс после установки преобразователей в гидросистему и соединени их с гидротестером. По приборам, показывающим среднюю величину давлени , угловую скорость вращени вала гидронасоса и температуру рабочей жидкости, устанавливаетс и поддерживаетс определенный режим работы диагностируемого гидропривода. После этого берутс отсчеты по приборам, показывающим величину расхода и величину пульсаций давлени , или производитс регистраци результатов измерений. Фиксируют наблюдаемую на экране осциллоскопа кривую изменени пульсаций давлени . Полученные Diagnostics is performed after installing the transducers in the hydraulic system and connecting them to the hydro tester. Instruments showing the average pressure, the angular velocity of rotation of the hydraulic pump shaft and the temperature of the working fluid establish and maintain a certain mode of operation of the diagnosed hydraulic drive. After that, readings are taken from the instruments, showing the magnitude of the flow rate and the value of the pressure pulsations, or the measurement results are recorded. The curve of pressure fluctuations observed on the oscilloscope screen is recorded. Received
результаты сравнивают с допустимыми (эталонными ) , на основании чего производ т оценку технического состо ни диагностируемой системы.the results are compared with the permissible (reference) ones, on the basis of which the technical condition of the system being diagnosed is assessed.
Изобретение позвол ет упростить конструкцию гидротестера и снизить трудоемкость диагностировани за счет уменьшени числа преобразователей.The invention allows to simplify the design of the hydrotester and reduce the laboriousness of diagnosing by reducing the number of transducers.
