10-100 Base-T

10-100 Base-T is the designation for Ethernet connections that support data transfer rates of 10 Mbps (megabits per second) and 100 Mbps. Here is the meaning of this label: Data transfer rate: The number "10" in 10-100 Base-T indicates a…

5G network

  Scheme of signal coverage and communication in a mixed 4G-5G network       The top of the mast with the antennas of the 5G network5G (short for 5th generation) is the fifth (latest in use) generation…

A backup source

A backup source is a system that includes a generator, fuel cells or batteries, and other electrical devices that, in the event of a power outage in the network, quickly ensure its restoration and short-term supply. In homes and offices, UPS…

A control insert

A control insert is a mechanical element that is used to control the flow of a liquid or gas in a pipe or system. It is a component that allows you to change the amount of fluid or gas that passes through the pipe, thereby affecting the pressure,…

A heating cable

A heating cable, also known as a heating cable, is an electrical cable designed to heat or defrost surfaces, especially in areas where ice, frost or snow accumulation may occur. These cables are used to maintain temperature in certain places…

A heating coil

A heating coil is a specific type of heat exchanger or heater that is used to transfer heat from one medium to another. This design is called a "spiral" because of its basic structure, which consists of bent tubes or pipes in a spiral…

A pipework

A pipework is a system of pipes that serves to transfer heat from burning fuel to a heat-carrying liquid, often water vapor. It is an important part of the boiler, which enables efficient combustion of fuel and heat exchange between the burning…

A pressure hose

A pressure hose is a flexible tube or hose that is used to transfer various liquids, gases or other media under pressure. Pressure hoses are usually made of a flexible material that allows them to adapt to the pressure and temperature of the…

A pressure station

A pressure station is a device used to control and maintain a constant pressure in a system, most often a water or hydraulic system. These stations are often used to ensure a consistent flow of liquid such as water, oil or other fluids in a…

A pressure switch

A pressure switch (also called a pressure sensor or pressure protection) is a device that is used to monitor and regulate the pressure in the system. Its main function is to switch the electrical circuit based on reaching a certain…

A sinusoidal output

A sinusoidal output is a type of output signal or a signal that takes the form of a sinusoidal waveform. A sinusoidal waveform is a mathematical form that has a curve shape similar to a sine function and is characterized by a periodic and…

A submersible pump

A submersible pump is a pump that is placed directly in the liquid it is supposed to pump. Its main characteristic is that it is completely immersed in the transported liquid, which makes it an efficient device for pumping large quantities of…

A synchronous motor

A synchronous motor is a type of electric motor that works by synchronizing the rotating magnetic field in the stator (the fixed part of the motor) and the rotating disk or rotor (the moving part of the motor). In a synchronous motor, the…

A thermostatic head

A thermostatic head is a device that is used to regulate the temperature in radiators or heating elements in heating systems. Its main function is to maintain a constant temperature in the room and regulate the supply of hot water to the…

A thermostatic mixing valve

A thermostatic mixing valve is a device that serves to maintain a constant temperature of water or other liquids when mixing hot and cold water. Its main function is to regulate the temperature of the outlet water to a preset value, which is…

Abrasiveness

Abrasiveness or scratchiness is the abrasive, abrasive effect of a substance on objects coming into contact with it.

Absorption

Absorption can be: in general and in medicine: absorption, absorption, amalgamationphysics and chemistry: the process of dissolving a gaseous compound in a liquid, or solid substancephysics:absorption of (light, X-ray, radioactive, etc.) radiation…

absorption layer

The absorption layer on solar collectors is a critical part of the device, which ensures efficient absorption of solar radiation and its conversion into heat. This layer is placed on the surface of the collector and is made of a material…

absorption surface

The absorption surface on solar collectors is the part of the collector surface that is responsible for absorbing solar radiation and converting it into heat. This surface is usually made of a material with high absorption capacity for solar…

accumulation tank

An accumulation tank is a device that serves to accumulate heat and then release it in heating or hot water heating systems. This tank is used to store the excess heat that is generated in the system when there is no need to use the heat at…

Accumulator

A battery is an electrical device that stores and releases electrical energy using chemical reactions. It is one of the most common electrical energy storage devices used for various purposes in households, industry and transport. How the…

Acetylén

Acetylene (ethine) is a hydrocarbon belonging to the group of alkynes. Its chemical formula is C2H2, which means it consists of two carbon atoms and two hydrogen atoms. It is a colored and colorless gas with a specific smell. Acetylene is known…

Acids

Acids, also called acids (commonly referred to as HA), are chemical compounds whose aqueous solutions have a pH lower than 7.0. This definition is an approximation of the modern Brønsted-Lowry concept, which defines an acid as a substance…

Acoustic pressure

Acoustic pressure is a physical quantity that describes the pressure of sound waves on a surface. It is a change in pressure caused by the fluctuation of the molecules of the medium in which the sound propagates. Acoustic pressure is one of the…

Active and passive cooling

Active and passive cooling are two different approaches to removing heat from different devices and systems. Here's the difference between the two methods, how they work, their advantages, and the areas where they're more suited: Active…
