ÜÇ KADEMELÝ DALGIÇ POMPALARIN PERFORMANS EÐRÝLERÝNÝN ÝNCELENMESÝ

Uluslararasý literatürde “Vertical Turbine Pump (VTP)” olarak adlandýrýlan pompalar seri pompa uygulamasý olarak düþey çalýþabilecek þekilde tasarlanmýþ pompalardýr. Günümüzde “Derin Kuyu Pompalarý (DKP)” olarak bahsedilen pompalar, yüzey kaynaklarýnýn yetersiz olduðu bölgeler için dar ve derin kuyularda çalýþabilme amaçlý geliþtirilmiþ pompalardýr. Bu pompalardan verimli bir þekilde yararlanmak için kademe sayýsýnýn uygun seçilmesi gerekmektedir. Bu çalýþmada; yeni bir dalgýç pompa dizayn edilmiþ, farklý kanat sayýlarýndaki (z = 3, 4, 5, 6, 7) üç kademeli dalgýç pompalarýn performanslarý deneysel olarak incelenerek tek kademeli dalgýç pompaya göre en iyi verim noktasýnda (b. e. p.) verim artýþ oranlarý hesaplanmýþtýr.

INVESTIGATION OF PERFORMANCE CURVES OF THREE STAGE DEEP WELL PUMPS

In literature, pumps which are known as vertical turbine pump (VTP) have been designed to work vertically. Today, they are known as deep well pumps. These pumps are especially used in narrow and very deep wells where the surface sources are insufficient. Therefore, it is necessary to select suitable stage number to benefit from deep well pumps efficiently. In this study, a new deep well pump has been designed and the performances of three stage deep well pumps have been investigated experimentally using different number of blades. Efficiency increase ratio of these three stage deep well pumps has been determined at the best efficiency point with respect to single stage deep well pumps.
