Abstract
Przedmiotem zgłoszenia jest urządzenie do wykonania rewizji zastępczej stałych zbiorników ciśnieniowych eksploatowanych na elektrowni wiatrowej oraz sposób wykonania warunków rewizji zastępczej stałych zbiorników ciśnieniowych w układach hydraulicznych elektrowni wiatrowej. Urządzenie ma falownik (1) turbiny wiatrowej do płynnej regulacji obrotów silnika elektrycznego (2) połączonego sprzęgłem z pompą zębatą (3), zawór zwrotny (4) zainstalowany na wyjściu (W) pompy zębatej (3) zapobiegający cofaniu się oleju hydraulicznego na pompę zębatą (3) i zawór przelewowy (5) oraz zawory iglicowe (P) na wyjściu urządzenia. Ponadto ma armaturę hydrauliczną połączeniową (7) składającą się z elastycznych węży hydraulicznych. Do zbiorników ciśnieniowych (12, 13, 14) układu hydraulicznego turbiny wiatrowej (10) podłączone są pary czujników pomiarowych emisji akustycznej AE (18, 19, 20) połączone przewodami komunikacyjnymi (15) poprzez system pomiarowy emisji akustycznej AE (16) z komputerem (17). Urządzenie podłącza się do układu hydraulicznego turbiny wiatrowej (10), następnie redukuje się ciśnienie w do poziomu 0 bar, a w kolejnych etapach zwiększa się ciśnienie oleju. Pary czujników pomiarowych emisji akustycznej AE (18, 19, 20), sprzężone z systemem pomiarowym AE (16) za pomocą przewodów komunikacyjnych (15), wysyłają sygnały, których odczyt pomiaru realizowany jest za pomocą komputera (17).The subject of the notification is a device for performing a replacement inspection of fixed pressure tanks operated in a wind farm and the method of performing the conditions of a replacement inspection of fixed pressure tanks in hydraulic systems of a wind farm. The device has a wind turbine inverter (1) for smooth adjustment of the speed of the electric motor (2) connected with a gear pump (3), a check valve (4) installed at the output (W) of the gear pump (3) to prevent backflow of the hydraulic oil to the gear pump (3) and an overflow valve (5) and needle valves (P) at the output of the device. In addition, it has a hydraulic connection fitting (7) consisting of flexible hydraulic hoses. To the pressure tanks (12, 13, 14) of the wind turbine hydraulic system (10), pairs of AE acoustic emission measuring sensors (18, 19, 20) are connected, connected by communication cables (15) through the AE acoustic emission measuring system (16) with a computer ( 17). The device is connected to the wind turbine's hydraulic system (10), then the pressure is reduced to 0 bar, and in the next stages the oil pressure is increased. The pairs of AE acoustic emission sensors (18, 19, 20), coupled with the AE measurement system (16) by means of communication cables (15), send signals, the measurement reading of which is carried out by a computer (17).
