THE PERFORMANCE OF WATER JET PUMPS AND THEIR APPLICATION IN SLURRY TRANSPORTATION

Öz:
This present work is focused firstly on an experimental investigation for the optimum design of water jet pumps to be used in the hydrotransport of solid particles through pipeline systems. Experiments were conducted in a closed test loop using five types of jet pumps with various dimensions of the driving nozzle, suction nozzle, mixing chamber, and diffuser employing water as driving and suction fluid. The efficiency of each water jet pump element was analyzed and interpretations of results related to each water jet pump were made about the parts to be considered in the optimum design of a water jet pump. From the experimental results, the water jet pump having the optimum mixing chamber, suction nozzle, driving nozzle location, and cross-sectional dimensions produced a maximum efficiency of about 33%. In the second part of the study, the solid particle carrying capacity of water jet pumps in a pipeline system was studied under saltation, moving bed, and heterogeneous flow regimes by introducing seven different types of solid particles having various concentrations into the closed test loop. The effect of jet pumps on separating solid particles from flow in a region was investigated. A curved form of a by-pass system called the ‘flow division unit’ was added to the main pipeline system and through the flow division unit, then most of the solid particles in the flow were forced to flow towards the suction pipe of the jet pump. As a result of this, only water with very small particle concentrations passed through the centrifugal pumps, and in this way, the wear risk of the centrifugal pump was reduced considerably.

SU JET POMPALARININ PERFORMANSI VE KATI-SIVI KARIŞIM TAŞIMACILIĞINDA UYGULANMASI

Öz:
Bu çalışma öncelikle, katı parçacıkların boru hattı sistemleri aracılığıyla suyla taşınımında kullanılacak su jeti pompalarının optimum tasarımı için deneysel bir araştırmaya odaklanmıştır. Deneyler, hem tahrik hem de emme sıvısı olarak su kullanan tahrik nozulu, emme nozulu, karıştırma haznesi ve difüzörün çeşitli boyutlarına sahip beş tip jet pompası kullanılarak kapalı bir test döngüsünde gerçekleştirildi. Her bir su jeti pompası elemanının verimliliği analiz edilmiş ve her bir su jeti pompasına ilişkin sonuçların, bir su jeti pompasının optimum tasarımında dikkate alınması gereken parçalar hakkında yorumları yapılmıştır. Deneysel sonuçlardan, optimum karıştırma haznesi, emme nozulu, tahrik nozulu konumu ve kesit boyutlarına sahip su jet pompası, yaklaşık %33'lük maksimum verimle üretilmiştir. Çalışmanın ikinci bölümünde, bir boru hattı sistemindeki su jeti pompalarının katı madde taşıma kapasitesi, çeşitli konsantrasyonlara sahip yedi farklı katı maddenin kapalı test döngüsüne sokularak sıçramalı, hareketli yatak ve heterojen akış rejimleri altında incelenmiştir. Jet pompasının bir bölgedeki katı partikülleri akıştan ayırmadaki etkisi araştırıldı. Ana boru hattı sistemine 'akış bölme ünitesi' adı verilen kavisli bir by-pass sistemi eklendi ve akış bölme ünitesi aracılığıyla, akıştaki katı parçacıkların çoğu jet pompasının emme borusuna doğru akmaya zorlandı. Böylece santrifüj pompalardan sadece çok küçük partikül konsantrasyonlarına sahip su geçmiş ve bu şekilde santrifüj pompanın aşınma riski önemli ölçüde azaltılmıştır.
