Vibration meter is an instrument used to directly indicate the peak value, peak-to-peak value, average value or root mean square value of vibration quantities such as displacement, velocity, acceleration and acceleration derivative. The main parts of this instrument are integral and differential circuit, amplifier circuit, voltage detector and…[Leia mais]

The paper box is a three-dimensional shape, which is composed of a polyhedron formed by moving, stacking, folding, and surrounding several surfaces. The faces in the three-dimensional composition play the role of dividing the space in the space. If the faces in different parts are cut, rotated, and folded, the obtained faces have different…[Leia mais]

A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer’s core, which induces a varying electromotive force across any other coils wound around the same core.…[Leia mais]

A spray dryer takes a liquid stream and separates the solute or suspension as a solid and the solvent into a vapor. The solid is usually collected in a drum or cyclone. The liquid input stream is sprayed through a nozzle into a hot vapor stream and vaporized . Solids form as moisture quickly leaves the droplets. A nozzle is usually used to make…[Leia mais]
