The technical task of creating new designs submersible vane pumps is to maintain stable operating parameters and increase the productivity pumping station with periodic regeneration sediment removal. well contains an outer chamber inner chamber, in which a unit installed, pipelines are connected lower upper pools. In structure under study, parts chambers equipped sealed head, part stopper. side...

The availability of various koi pond pump products is marketed with kinds, types, and advantages. This diversity makes it difficult for business owners to determine a product that suits their needs. consideration the in question form an electric submersible or ESP. One method can be used selection AHP (Analytical Hierarchy Process) method. study uses assisted by expert choice software. From res...

This paper analyzes the dynamic properties of a submersible drogue for which buoyancy control is implemented by a flexible membrane and pneumatic actuation. It is shown how a simple on/off switching algorithm tuned on the basis of depth measurements and an estimated depth velocity can be used to achieve accurate depth control with small fluctuations. The switching control makes the pneumaticall...

In order to clarify the non-constant flow characteristics of impeller and bulb body submersible tubular electric pump device, entire rate conduit device is numerically calculated using numerical simulation method, focusing on analysis field guide vane time–frequency variation law pressure pulsation, results physical model testing confirm validity simulation. The findings demonstrate that a most...

Wave run-up is one of the most important and effective parameters in designing semi-submersible platforms. Besides unforeseen effects on the movements and response of the platform, wave run up can also cause slamming forces to be exerted on the lower deck of the platform. Therefore, at the first stages of this plan, before running tests on the model of the platform, numerical methods are usuall...
