Pumping viscous fluids using centrifugal pumps in the subsea industry is very common. The pump performance degrades drastically when viscosity of increases, which ultimately gives rise to installation and oil production cost. Their design optimization can lead a significant improvement their performance. Therefore, this study presented effect impeller geometry on pumping fluid through optimizat...

Centrifugal pump, which is widely used in water conservancy, electric power, petrochemical, ship, aerospace, and other technical fields, the core equipment to ensure all kinds of energy transfer. Cavitation not only affects service life centrifugal pump but also seriously impacts reliability process flow or device system. Due influence life, position number vibration sensors, existing cavitatio...

The following scenarios explore some of the common problems encountered during extracorporeal membrane oxygenation (ECMO) in adults. In each scenario, the circuit is comprised of a centrifugal pump and a polymethylpentene oxygenator.

In Egypt, surface irrigation is the most commonly used method comparing with the other irrigation systems in old land. In addition, centrifugal instruments are prevailing used for irrigating fields. However, the major problem who confronts the farmers at operating these instruments is priming it to be operating by filling the water to replace the air in pipes. To be prime the instrument need tw...

Inducer is often used to improve the cavitation performance of pump. In order study characteristics inducer under low flow condition high-speed pump, photography technology was employed in this paper carry out visual experiments on a centrifugal rates, Cavitation distribution and evolution among were captured. The experimental results revealed that band-shaped backflow vortex inlet pipe would o...

Centrifugal pumps are divided into two main components, namely the impeller and volute. The is a rotating pump component, while volute stationary component. current problem in industrial world that capacity operates not accordance with written so does work optimally. In addition, structural analysis of minimally carried out damage to often occurs. To overcome this, it necessary analyze performa...

Centrifugal blood pumps have provided a powerful artificial support system for patients with vascular diseases. In the design process, geometrical optimization is usually needed to acquire more biocompatible model clinical uses. current paper, we propose method multi-objective concerning both hydraulic and hemolytic performances of pump based on near-orthogonal array in which traditional hemoly...

Centrifugal pumps are considered to be less destructive to blood elements (1) when compared to roller pumps. However, their large prime volumes render them unsuitable as arterial pumps in heart lung machine (HLM) circuitry for children. In November of 2014, the circuit at Arnold Palmer Hospital, a Biomedicus BP-50 with kinetic assist venous drainage (KAVD) and 1/4″ tubing was converted to a rol...

A multistage centrifugal pump is designed for pumping low-viscosity, highly volatile and flammable chemicals, including hydrocarbons, high head requirements. The five-stage consists of a double-suction impeller at the first stage followed by twin volute. impellers stages two through five are single-suction diffuser vanes return channel vanes. analytical performance calculated initially in desig...

The inducer is a very small booster pump, lifting the suction pressure to a sufficient level for the main conventional impeller. By adding the inducer to high speed centrifugal pumps, NPSHr can be reduced to a great extent. Liquid with high gas content can be pumped successfully with inducer equipped pumps. Even low NPSHr allows a smaller, higher speed low horsepower pump, saving energy and cap...
