Abstract

Su, insan hayatının vazgeçilmezi olup yerleşim yerlerinde temiz suyun temini ve atık suyun uzaklaştırılması zorunlu ihtiyaçtır. Bu zorunlu ihtiyaç gelişen teknoloji ile birlikte farklı yöntemlerle karşılanmaktadır. Arşimet pompalar da su temini ve atık suyun uzaklaştırılmasında kullanılan en eski akım makineleridir. Bu çalışmada Klasik Arşimet Pompa’ya alternatif olarak geliştirilmiş olan Dış Çeperli Arşimet pompanın performansı ve kova doldurma performansı incelenmiştir. Tasarımı yapılan dış çeperli Arşimet pompanın basma yüksekliği 6 metre, basma açısı 30° olacak gerçek boyutlarının 1/20 ölçeği referans alınarak tasarlanmıştır. Tasarımın farklı basma açılarındaki performansını değerlendirmek için 20°, 30°, 40° basma açılarında analizler ve deneyler yapılmıştır. Hesaplama ile elde edilen kova hacimleri geometrik analiz ile elde edilen hacimlerinden %15 daha büyüktür. Ancak deneysel olarak elde edilen kova hacimleri hesaplama ile elde edilen hacimlerin azami %37’sine karşılık gelmektedir. Bu durum dış çeperli Arşimet pompa tasarımında memba tarafının suya batma miktarının kova doldurma oranını doğrudan etkilediğini göstermektedir. Ayrıca kova hacmi hesaplamalarında CAD modeli üzerinden yapılan hacimsel analizler Arşimet pompaların kova hacimlerini daha net bir şekilde hesaplayabilmektedir.

INVESTIGATION OF THE BUCKET VOLUME PERFORMANCE OF THE OUTER WALLED ARCHIMEDEAN PUMP ACCORDING TO THE MOUNTING ANGLE

Abstract

Water is indispensable for human life and supply of clean water and removal of waste water in settlements is a compulsory need. This compulsory need is met by different methods with the developing technology. Archimedes pumps are the oldest current machines used in water supply and waste water removal. In this study, the performance and bucket filling performance of the outer wall Archimedes pump, which has been developed as an alternative to the classical Archimedes pump, has been investigated. The design of the outer wall Archimedes pump with a head of 6 m and a discharge angle of 30° is based on 1/20 scale of the actual dimensions. In order to evaluate the performance of the design at different discharge angles, analyses and experiments were performed at 20°, 30°, 40° discharge angles. The bucket volumes obtained by calculation are 15% larger than the volumes obtained by geometrical analysis. However, the experimentally obtained bucket volumes correspond to a maximum of 37% of the volumes obtained by calculation. This shows that the amount of submergence of the upstream side in the outer wall Archimedes pump design directly affects the bucket filling rate. In addition, volumetric analyses made on the CAD model in bucket volume calculations can calculate the bucket volumes of Archimedes pumps more clearly.
