TARIFNAME MONOBLOK YAPIDA HIDROLIK TAHRIKLI KISA YATAKLI POMPA YAPILAN MAsi TEKNIK ALAN Bulus, makine, imalat, enerji, atik su, denizcilik, bina teknolojileri, endüstriyel uygulamalar olmak üzere birçok alanda akiskanlarin transfer isleminde kullanilan pompalarda; monoblok yapida hidrolik tahrikli santrifüj pompalar tasarlanirken pompa boyutunu azaltmak, maliyeti düsürmek, daha sessiz bir çalisma ortami saglamak ve pompa verimini yükseltmek amaciyla teknigin bilinen durumunda kullanilan pompalardan daha kisa tasarlanarak zamanla milde meydana gelecek eksen kaymalarini minimuma indirilmesini içeren yapilanma ile ilgilidir. ÖNCEKI TEKNIK Santrifüj pompalar, hidrolik olarak çalisan ve motorlarindan aldiklari dönme enerjisini akiskanlara aktaran makinelerdir. Esas amaçlari, akiskanlarin basincini yükselterek aktarmaktir. Farkli yapilara sahip olsalar da çalisma prensipleri ve akiskan dinamigi karakteristikleri her zaman aynidir. Esasen santrifüj pompalar, mahfaza içinde dönen bir çarktan olusur. Bu çark, kinetik enerjiyi pompalanan siviya ileten, tercihen radyal tasarimli bir dizi kanat içerir. Gövde üzerinde akiskan için emme ve bosaltma nozullari yer alir. Emme nozulu, çarkin dönme ekseniyle örtüsen bir eksendeyken, bosaltma nozulu ekseniyse bu ikisine dik bir konuma sahiptir. Pompalanan sivi, çarkin ortasindaki pompanin emme agzindan sürekli olarak giris yapar. Buradan çarkin en uç noktasina kadar radyal yönde hizlanir ve ardindan mahfaza içine bosalir. Akiskan hizi, çark kanatlarinin egimli olmasi sayesinde aldigi itme kuvvetiyle artar. Bu sekilde sivi, ortalama hizini arttirirken ayni zamanda enerji kazanir. Gövde içinde, hareket yönünde kademeli olarak genisleyen bölüm sayesinde sivinin hizi kontrollü olarak azalir. Bunun gibi bir kesit artisi genellikle mahfazanin çevresel parçasinin enine kesitli bir spiral seklinde tasarlanmasiyla saglanir. Bu sekilde akiskanin sahip oldugu kinetik enerji basinç enerjisine dönüsür. Mahfaza emme agzinin karsisindaki kisimdan kapak ile kapalidir. Kapagin mil geçisinin bulundugu orta kisminda salmastranin muhafaza edildigi bir odacik bulunur. Yüksek basinç bölgesi (gövdenin içinde) ve düsük basinç bölgesi (emme nozulu) arasindaki sizdirmazlik, çark ve gövde arasindaki düsük mesafeli bosluk sayesinde saglanir. Çark ve mil, özel bir destek içinde mahfazanin disinda bulunan iki yatakla desteklenir. Santrifüj pompalar akiskani bir yerden baska bir yere transfer eden enerji tüketen makinalardir. Santrifüj pompalar belli bir enerji kaynagindan tahrik edilir. Genellikle elektrik motorlari ya da dizel motorlari ile tahrik edilmektedir. Santrifüj pompalar araç içi ekipman olarak da kullanilmaktadir. Araç içi sistem olarak kullanildiginda tahrigini kullanilan aracin yag basincindan elde etmektedir. Ancak burada gerekli olan baglanti araçta büyük bir yer kaplamaktadir.

TR TR TR TR TR TR TR TRDESCRIPTION HYDRAULIC SHORT-BEARING PUMP WITH MONOBLOCK STRUCTURE TECHNICAL FIELD The invention relates to the design of monoblock hydraulically driven centrifugal pumps used in the transfer of fluids in many areas including machinery, manufacturing, energy, wastewater, maritime, building technologies, and industrial applications. This design involves minimizing shaft misalignment over time by designing shorter pumps than currently used pumps in order to reduce pump size, reduce costs, provide a quieter operating environment, and increase pump efficiency. PREVIOUS TECHNICAL FIELD Centrifugal pumps are hydraulically operated machines that transfer rotational energy from their motors to fluids. Their primary purpose is to increase fluid pressure and transfer fluids. Although they have different structures, their operating principles and fluid dynamics characteristics are always the same. Essentially, centrifugal pumps consist of an impeller rotating within a casing. This impeller contains a series of vanes, preferably of radial design, that transfer kinetic energy to the pumped liquid. Suction and discharge nozzles are located on the casing for the fluid. The suction nozzle is oriented on an axis that coincides with the impeller's axis of rotation, while the discharge nozzle is oriented perpendicular to these two. The pumped liquid continuously enters the pump's suction port at the center of the impeller. From there, it accelerates radially to the tip of the impeller and then discharges into the casing. The fluid velocity is increased by the thrust force exerted by the inclined impeller vanes. In this way, the liquid increases its average speed and simultaneously gains energy. The fluid velocity decreases in a controlled manner within the casing thanks to a section that gradually widens in the direction of motion. Such an increase in cross-section is usually achieved by designing the circumferential section of the casing as a spiral cross-section. In this way, the kinetic energy of the fluid is converted into pressure energy. The casing is closed by a cover on the side opposite the suction nozzle. The middle section of the cover, where the shaft passage is located, contains a chamber housing the packing. Sealing between the high-pressure zone (inside the casing) and the low-pressure zone (suction nozzle) is achieved by the small clearance between the impeller and the casing. The impeller and shaft are supported by two bearings located outside the casing within a special support. Centrifugal pumps are energy-consuming machines that transfer fluid from one location to another. Centrifugal pumps are driven by a specific energy source. They are generally driven by electric motors or diesel engines. Centrifugal pumps are also used as in-vehicle equipment. When used as an in-vehicle system, they are driven by the vehicle's oil pressure. However, the required connection takes up a large amount of space in the vehicle. Some other problems that may arise due to the pump's size include: - High infrastructure and production costs, - Negative effects on surrounding living things and electro/mechanical structures due to high noise, - Pump not operating at high performance and stability due to high vibration, - Need for constant air purging of the pump, - Low pump speed, - Foreign material accumulation and sedimentation inside the pump that will affect performance, - Pump operating at low speed due to insufficient pressure, - Lengthy pump assembly/disassembly processes, - High pump maintenance/repair costs, - Axis misalignment of the shaft. According to our searches in the Turkish patent database, no application compatible with our invention was encountered. As a result, due to the drawbacks encountered in the state of the art and described above, the need for improvements in the construction of monoblock hydraulically driven short-bearing pumps has arisen. OBJECTIVES OF THE INVENTION The purpose of the invention relates to the construction of monoblock hydraulically driven centrifugal pumps used in the transfer of fluids in many areas including machinery, manufacturing, energy, wastewater, marine, building technologies, and industrial applications; in order to reduce pump size, reduce costs, provide a quieter operating environment, and increase pump efficiency, designing shorter pumps than those used in the state of the art to minimize axial misalignment that will occur on the shaft over time. Due to the drawbacks existing in the prior art, the invention aims to resolve all of the drawbacks described. The general purpose of the invention is to reduce pump size when designing monoblock hydraulically driven centrifugal pumps; - to reduce costs, - to provide a quieter operating environment, and - to increase pump efficiency. Another purpose of the invention is to minimize shaft misalignment over time by designing a shorter shaft length, between 300 and 500 mm, than the current state-of-the-art design. Another purpose of the invention is to eliminate the coupling between the drive element and the pump and reduce the bearing size, saving both space and cost. Another purpose of the invention is to eliminate all problems arising from pump and hydraulic motor alignment. Another purpose of the invention is to reduce mechanical losses by mounting the bearing directly to the end of the pedestal. Another purpose of the invention is to provide ease of service in narrower spaces thanks to its low-noise, compact design. The advantages of the invention over the state of the art are: - low infrastructure and production costs, - thanks to low noise, no negative effects on surrounding living things and electro/mechanical structures, - thanks to the reduction of vibration effect, the pump operates at high performance and stability, - eliminating the need for constant airing of the pump, - ensuring that the pump speed operates at maximum levels and full capacity, - reducing and/or eliminating the accumulation of foreign matter and sedimentation that may affect the performance inside the pump, - short pump assembly/disassembly processes and service times, - low pump maintenance/repair costs, - reducing and/or eliminating axis shifts that may occur on the shaft.

The invention is connected to the channel (201) through which the fluid on the drive element (200) enters and exits, using a source taken from an oil tank or the hydraulic circuits in the vehicle.
