Abstract

W jednym przykladzie wykonania symulator ukladu krazenia zawierajacy sterowane elektrycznie zródla cisnienia i strumienia cieczy oraz przetworniki cisnienia na sygnal elektryczny ma postac bloku elektrohydraulicznego zbudowanego z kilku, korzystnie z dwu do czterech modulów funkcjonalnych (S1 do S4), z których kazdy zawiera jedno elektrycznie sterowane zródlo (I) cisnienia lub strumienia cieczy majace jeden hydrauliczny kanal wejsciowy (15) polaczony ze zbiornikiem cieczy roboczej (20) oraz jeden hydrauliczny kanal wyjsciowy (16) polaczony z robocza komora hydrauliczna (10) modulu, przy czym te robocze komory hydrauliczne sa korzystnie umieszczone szeregowo w jednym bloku hydraulicznym, w którym wspólne scianki komór maja otwory robocze (8), w których sa umieszczone hydrauliczne elementy w postaci np. sztucznych zastawek serca, rur hydraulicznych lub plytek (9) odcinajacych przeplyw cieczy. W kazdej komorze roboczej (10) modulu funkcjonalnego jest umieszczony przetwornik cisnienia na sygnal elektryczny. Kazda z hydraulicznych komór roboczych symulatora jest polaczona z kanalem wejsciowym przeciazeniowego zaworu bezpieczenstwa oraz kanalem wyjsciowym recznego lub elektrohydraulicznego zaworu odcinajacego, których kanaly wyjsciowe sa polaczone ze zbiornikiem plynu roboczego (20). W kazdej z bocznych scianek komór roboczych, które nie sa ich sciankami wspólnymi, sa wykonane otwory (7) laczace komory robocze z badanymi urzadzeniami (4) wspomagania krazenia, a kazda komora robocza (10) w swojej górnej sciance ma otwór laczacy ja z kanalem wejsciowym kondensatora hydraulicznego korzystnie typu pneumohydraulicznego.In one embodiment, a circulatory system simulator containing electrically controlled pressure and fluid stream sources and pressure transducers for an electric signal has the form of an electrohydraulic block made of several, preferably two to four functional modules (S1 to S4), each containing one electrically controlled source (I) pressure or fluid stream having one hydraulic inlet channel (15) connected to the spray liquid tank (20) and one hydraulic outlet channel (16) connected to the hydraulic working chamber (10) of the module, these hydraulic working chambers being preferably arranged in series in one hydraulic block, in which the common walls of the chambers have working holes (8), in which hydraulic elements are placed in the form of e.g. artificial heart valves, hydraulic pipes or plates (9) cutting off the flow of liquid. In each working chamber (10) of the functional module there is a pressure transducer for an electric signal. Each of the hydraulic working chambers of the simulator is connected to the input channel of the overload safety valve and the output channel of a manual or electrohydraulic shut-off valve, whose output channels are connected to the working fluid tank (20). In each of the side walls of the working chambers, which are not their common walls, there are holes (7) connecting the working chambers with the tested devices (4) for circulatory support, and each working chamber (10) in its upper wall has a hole connecting it with the channel of the hydraulic condenser input, preferably of the pneumohydraulic type.
