WebThe diaphragm, or cone, of such a loudspeaker moves with the coil, converting the electric current in the coil into a pressure wave. A lit candle placed in front of a loudspeaker cone that is oscillating at about 10 hertz can render the sound wave “visible,” as the flame vibrates back and forth longitudinally with the air. WebOn engines that use a carburetor (e.g. in older cars, lawnmowers and power tools), a mechanical fuel pump is typically used in order to transfer fuel from the fuel tank into the carburetor. These fuel pumps operate at a relatively low fuel pressure of 10–15 psi (0.7–1.0 bar). The two most widely used types of mechanical pumps are diaphragm ...
WebA compressed gas accumulator consists of a cylinder with two chambers that are separated by an elastic diaphragm, a totally enclosed bladder, or a floating piston. One chamber contains the fluid and is connected to the hydraulic line. WebBefore the invention of electromagnetic telephones, mechanical acoustic devices existed for transmitting speech and music over a greater distance. This distance was greater than that of normal direct speech. The earliest mechanical telephones were based on sound transmission through pipes or other physical media. The acoustic tin can telephone, or …
WebA rupture disk, also known as a pressure safety disc, burst disc, bursting disc, or burst diaphragm, is a non-reclosing pressure relief safety device that, in most uses, protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions. WebMechanical gauges: These use some form of mechanical linkage or diaphragm arrangement that does not require onics. The arrangement physically moves an electr indicator needle that shows the pressure or vacuum. • Thermal gauges: Commonly referred to as Pirani, thermocouple, and convection gauges, these function
WebShear pins as safeguards. In the role of a mechanical safeguard, a shear pin is a safety device designed to shear in the case of a mechanical overload, preventing other, more expensive or less-easily replaced parts from being damaged. As a mechanical sacrificial part, it is analogous to an electric fuse.. They are most commonly used in drive trains, …
