Description
Имитаци и измерение забросов и провалов давлени в топливных системах позвол ют определ ть минимальное врем изменени расхода рабочей жидкости, при котором величина заброса или провала дав .лени не превышает допустимых величин.Simulation and measurement of overshoots and pressure dips in fuel systems allow determining the minimum time of change in the flow rate of the working fluid, at which the magnitude of the overflow or pressure dip does not exceed the permissible values.
Известны способы имитации гидравлических ударов при испытании гидросистем, заключающиес в резком изменении расхода потока жидкости путем открыти или закрыти кранов-заслонок.Methods are known for simulating hydraulic shocks when testing hydraulic systems, which consist in a drastic change in the flow rate of a fluid flow by opening or closing valve-valves.
Предлагаемый способ имитации забросов и провалов давлени в топливных системах при их стендовых испытани х отличаетс от известных тем, что забросы и провалы давлени вызывают тарированным по времени изменением расхода рабочей жидкости при помощи крана-заслонки, управл емого электро-пнематическим струйным реле через сервопоршень.The proposed method for simulating intakes and pressure dips in fuel systems during their bench testing differs from the known ones in that pressure and pressure dips cause a time-calibrated change in the flow rate of the working fluid using a valve controlled by an electro-pneumatic jet relay through a servo piston.
На чертеже приведена примерна схе.ма установки дл испытаний систем по предложенному способу.The drawing shows an exemplary installation setup for testing systems according to the proposed method.
Насос / перекачивает рабочую жидкость по трубопроводу 2 из бака 3 через кран-заслонку 4 и расходомер 5. Давление на входе и выходе из насоса измер етс мано.метрами 6 н 7. Два датчика 8 н 9 давлени выдают сигналы на осциллограф 10, а датчик // выдает на осциллограф сигнал, пропорциональный перепаду давлений до и после сопла насоса /, что в определенно.м масщтабе соответствует расходу рабочей жидкости.The pump / pumps the working fluid through pipeline 2 from tank 3 through valve 4 and flow meter 5. The pressure at the pump inlet and outlet is measured with 6 n 7 meters. Two 8 n 9 pressure sensors send signals to an oscilloscope 10, and a sensor // outputs to the oscilloscope a signal proportional to the pressure differential before and after the pump nozzle /, which on a definite.m scale corresponds to the flow rate of the working fluid.
Изменение режима перекачки рабочей жидкости осуществл етс краном-заслонкой 4 при помощи сервопорщн 12, управл емого электрОПневматическим струйным реле J3.The change in the pumping mode of the working fluid is performed by the valve 4 with the help of servo valves 12, controlled by the electropneumatic jet relay J3.
Врем перемещени крана-заслонки 4 определ етс величиной сигнала, подавае.мого на обмотку 14 управлени реле, и осуществл етс следующим образом.The travel time of the valve 4 is determined by the magnitude of the signal supplied to the relay control winding 14, and is performed as follows.
