The Samsung Galaxy S23, which takes an input current of 3 A, can charge its internal battery packs at 6 A thanks to a 2:1 current pump. [3] Oppo's 240 W SUPERVOOC goes further and uses three charge pumps in parallel (98% claimed efficiency [4]) to go from 24V/10A to 10V/24A, which is then taken by two parallel battery packs. [5]
As mentioned, HPLC relies on pumps to pass a pressurized liquid and a sample mixture through a column filled with adsorbent, leading to the separation of the sample components. The active component of the column, the adsorbent, is typically a granular material made of solid particles ( e.g. , silica , polymers, etc.), 1.5–50 μm in size, on ...
Presently, about one third (approximately 2 gigatons of carbon per year) [2] [3] of anthropogenic emissions of CO 2 are believed to be entering the ocean. The solubility pump is the primary mechanism driving this flux, with the consequence that anthropogenic CO 2 is reaching the ocean interior via high latitude sites of deep water formation ...
The type of pump used varies. Gear pumps [1] [2] trochoid pumps [3] and vane pumps [a] are all commonly used. Plunger pumps have been used in the past, but these are now only used rarely, for small engines. To avoid the need for priming, the pump is always mounted low-down, either submerged or around the level of the oil in the sump. A short ...
An electromagnetic pump is a pump that moves liquid metal, molten salt, brine, or other electrically conductive liquid using electromagnetism. A magnetic field is set at right angles to the direction the liquid moves in, and a current is passed through it. This causes an electromagnetic force that moves the liquid.
Electromagnetic rotation experiment of Faraday, ca. 1821 [2] Working principle of a homopolar motor: due to movement of negative charges from center towards rim of the disk, a Lorentz force F L is created which brings the entire disk into rotation. The homopolar motor was the first electrical motor to be built.
The basic working principle of an air-operated double diaphragm pump. Cross-section sketch of diaphragm fuel pump Air-operated double diaphragm pump. A diaphragm pump (also known as a Membrane pump) is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable valves on either side of the diaphragm (check valve ...
A pump-jet works by having an intake (usually at the bottom of the hull) that allows water to pass underneath the vessel into the engines. Water enters the pump through this inlet. The pump can be of a centrifugal design for high speeds, or an axial flow pump for low to medium speeds. The water pressure inside the inlet is increased by the pump ...
