Each of us has touched and used electricity to the ground, but there are not many people who know about electricity. For some employees in the electrical industry. The electrical knowledge I know is not very comprehensive. Here we introduce the little electrical knowledge that seldom people pay attention to. Maybe it will bring some help to your future work.
Electricity is a general term for disciplines or engineering fields such as the production, transmission, distribution, use of electrical energy, and electrical equipment manufacturing. It is a science to create, maintain and improve confined space and environment by means of electric energy, electric equipment and electric technology, covering three aspects of electric energy conversion, utilization and research, including basic theory, applied technology, facilities and equipment.
It is a formula for calculating how to divide the total voltage of each resistor in series and how much voltage is divided into. How much of the sub-voltage is calculated as follows: the percentage of the total resistance is the percentage of the sub-voltage.
American science and technology awards pay more attention to honor. National awards such as the National Science Award, National Technology Award, and Fermi Award have no bonuses. In our country, with the continuous deepening of the reform process, we have gone from one misunderstanding to another.
In addition to meeting basic needs, award-winning designs must also achieve both “innovation” and “impact”. In this particular year of 2020, the judges’ favourite works share the common goal of “making the world a better place”, which is also the microcosm of contemporary Australian design. This year’s most prestigious awards, design of the year and Patron of the Year, were awarded to outstanding technology in the medical field.
When designers are working on different design requirements, product design methodology can provide designers with clear steps and frameworks; how designers should think when designing products, and from which direction to think in order to design products with good user experience ; The author of this article shared about the design values in the product design methodology, let’s take a look.
After combining personal experience and product experience, the author shared with us his seven thoughts on making products, hoping to bring you thoughts and inspiration.
Stepping motor is an open-loop control element that converts electrical pulse signals into angular displacement or linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequency and pulse number of the pulse signal, and are not affected by the load change, that is, when a pulse signal is added to the motor, the motor will rotate through a step angle.
Since the new crown epidemic, masks have once become one of the most important materials in the world. Generally, protective masks have a three-layer structure, and the outer layer has an anti-droplet design (spunbonded non-woven fabric) + middle layer filtration (meltblown non-woven fabric) + inner moisture absorption (spunbonded non-woven fabric). Among them, the meltblown cloth, which is the “heart of the mask”, has high requirements for the plant environment due to the huge investment in the production line, the high technical content, the complicated equipment installation, and the environment.
Recently, the World Economic Forum and the “Scientific American” magazine jointly released the “Top Ten Emerging Technologies of 2020”. The international expert steering group selected these technologies from 75 technical nominations.
In order to ensure the quality of the project and extend the service life, metal accessories such as pipe clamps, brackets, hooks, pull rings and box (box) bolts, nuts and other ferrous metal accessories used in wiring and electrical installation lighting projects are required. All should be galvanized or coated with anticorrosive paint.
2020.5.4 Update 15-November-2022 Assemblies Resolved an issue where “Place and ground first component at origin” is not working when copying multiple components between assemblies. INVGEN-64903 Translators – DWF Resolved an issue where the dimension text…
Many applications of lightweight conveyor belts require it to be tensioned first, and then to change its length by adjusting any rollers. In this case, the tension in the belt will change throughout the life of the belt.
Is it designed based on KKD (experience, intuition and courage) alone? Explain the advantages and necessary knowledge of tolerance design concisely and easily!
Everyone has their own ideas when programming PLC, even if the same control logic is written by different engineers, they will get different results. Even the same engineer has different ideas at different times.
