3454 results about "Centrifugal pump" patented technology

Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from which it exits.

Computational fluid dynamics (CFD)-based centrifugal pump multi-working condition hydraulic power optimization method

The invention discloses a computational fluid dynamics (CFD)-based centrifugal pump multi-working condition hydraulic power optimization method. The method comprises the following steps of: 1, establishing an initial specimen bank for centrifugal pump multi-working condition hydraulic power optimization on the basis of external characteristic tests; 2, establishing a CFD-based centrifugal pump multi-working condition hydraulic power optimization model; 3, generating a specimen bank for the centrifugal pump multi-working condition hydraulic power optimization and constructing a response surface approximate model by CFD technology on the basis of single point hydraulic design and uniform design methods; 4, globally optimizing the approximate model by a global optimization algorithm; and 5, performing hydraulic power design on a centrifugal pump by a parametric computer aided design (PCAD) according to optimization results so as to obtain a multi-working condition hydraulic power model of the centrifugal pump.

The United States of America consumes nearly 20 million barrels of oil a day, 6.6 billion per year. This depleting chemical composition, in part, ends up in our air, on our trees, on our clothing, in our lungs, in our blood streams. A large portion of this oil is imported causing a dependency on foreign countries and a significant economic burden to this country. Clean, renewable, domestic energy is a necessity, not a luxury. The Z-333 Energy Management System is an answer to this challenge. There have been many Vertical Axis Wind Turbine patents issued since Mr. Elhanan L. Stoners' patent in 1891. However it appears that none has yet manifested itself into a large scale economic reality. The Z-333 Energy Management System is the latest of a series of improved Vertical Axis Wind Turbine designs which will make that reality come to pass. The Z-333 Energy Management System includes several novel changes to previously patented designs, plus incorporates totally new accessories to make man's continuing conquest of wind an actuality. These innovations include; Aerodynamic “balanced” wings. Tightly stretched fabric-only wings strengthening the overall structure, and at the same time, drastically lower the cost of construction. Flexible photovoltaic cells cover the aforementioned fabric-only-wings. A rotating tower that is flexible and safer. A unique high winds shut off switch. A multi-generator braking system maintains the shaft at a constant RPM. Generators and gears mounted to removable panels. Rubber-like covered shaft and large ring transmission. A low cost switch that controls the angle of attack of the wing with less problems and cost. A tower made of prefabricated interchangeable modules that can be used as a home, water tank, storage room, shop, and/or a shed. A base which is also a large battery and/or a control box shell. A programmable intelligent control box, which notifies the owner by cell phone, of battery fast charge/discharge, vandalism, key energy indicators, integrates a multi-circuit station timer, plus provides an electric-fence-like shock protection from animals and vandals. Low cost, multi-pancake generator that is highly efficient. A shaft centered flywheel. A shaft centered centrifugal pump. A sea base with ballast for low cost erection. A sea base with desalinization equipment built inside. A sea base with integrated hydrogen and oxygen producing equipment.

Centrifgal pump

The invention is related to a centrifugal pump with an existing pump housing made of plastic material that can be processed through injection molding, having a first housing section, featuring a suction nozzle and a pressure nozzle, a second housing section supporting an electronically commutated DC motor and a split case, a motor housing section that closes a dry chamber separated from a wet chamber by the split case in which a stator and an electronic component are arranged, and a permanent magnet rotor that is mounted in the wet chamber in such a way that it can rotate, and drives a pump impeller that reaches into the pump chamber. The electronic components are arranged on an electronic circuit board aligned at right angles to an axle and parallel to a base of the split case. The electronic circuit board is in heat conducting contact with the base. The task of the invention is to cool electronic components sensitive to heat in a simple way and with a high degree of efficiency such that a simple installation of the electronic components is guaranteed and only a small number of parts is required, the construction space being as small as possible. According to the invention, this problem is solved by the fact that one or several conductors of the electronic circuit board are in heat conducting contact with the base.
