Abstract AR
التكهف أحد العيوب الخطيرة في التوربينات الهيدروليكية التي تؤثر سلبا على كفاءتها و قد يسبب أضرارا فيها.
و هو يظهر في شكل تنقر على سطح أجزاء التوربينات مسببا أشكالا مجوفة.
في هذه الورقة تمت دراسة و تحليل التكهف في توربين كابلان وحده 2 في محطة كهرباء الرصيرص، أثناء فترات الفيضان و انحسار الماء و الإظلام التام .
إن السمات العامة لهذه الظاهرة تم توصيفها و تحديد عواملها.
كما تم حساب و مقارنة مؤشرات التكهف و عوامله الحرجة في الفترات الثلاثة.أظهرت النتائج إن التوربين يعمل في مدى حد التكهف، أثناء هذه الفترات.
وأن أعلى مؤشر للتكهف وجد في فترة الانحسار بينما وجد اقل قدرة و هبوط في الضغط في فترة الفيضان و الإظلام التام و هذا أيضا يزيد من احتمال حدوث التكهف.
Abstract EN
Cavitation is one of the serious problems in hydraulic turbines negatively affects their efficiency and may cause damages.
Cavitation is a phenomenon which occurs as a pitting of metallic surfaces of turbine parts because of the formation of cavities.
In this paper, cavitation in Kaplan turbine unit 2 in Rosieres power plant was studied and analyzed during flood, water restriction and blackout periods.
The general features of cavitation were described and cavitation variables were determined in the plant.
Cavitation indexes and critical cavitation factors were calculated and compared during these three periods.
The results showed that: the turbines were operated within cavitation limit during these periods.
Cavitation index was found to be higher in water restriction, while minimum power and drop of pressure, which also increase the possibility of cavities were found in flood and blackout.
