Electrical Symbols, Electrical Diagram Symbols

Electrical Diagram Symbols
When drawing Electrical Schematics, Electrical Circuit Diagrams, Power Systems Diagrams, Circuit and Wiring Diagrams, Digital and Analog Logic Schemes, you will obligatory need the electrical symbols and pictograms to represent various electrical and electronic devices, such as resistors, wires, transistors, inductors, batteries, switches, lamps, readouts, amplifiers, repeaters, relays, transmission paths, semiconductors, generators, and many more. Today these symbols are internationally standardized, so the diagrams designed using them are recognizable and comprehensible by specialists from different countries. Electrical Engineering Solution included to ConceptDraw Solution Park provides 26 libraries with 926 commonly used electrical schematic and electrical engineering symbols making the reality the easy drawing of Electrical diagrams, schematics and blueprints. Now you need only a few minutes to create great-looking Electrical diagram, simply choose required electrical design elements from the libraries, drag them on the needed places at the document and connect in a suitable way.

Process Flow Chart Symbol

Process Flow Chart Symbol *
Process Flow Charts are very popular and widely used in chemical and process engineering for representation a general flow of plant processes and equipment. If you need often draw them, the ConceptDraw DIAGRAM diagramming and vector drawing software extended with tools of Flowcharts Solution will be useful for you. The mostly used set of process flow chart symbols includes the following: Rectangle (box) process flow chart symbol, Rounded rectangle, Circle, Diamond.
"The symbols and conventions used in welding documentation are specified in national and international standards such as ISO 2553 Welded, brazed and soldered joints -- Symbolic representation on drawings and ISO 4063 Welding and allied processes -- Nomenclature of processes and reference numbers. The US standard symbols are outlined by the American National Standards Institute and the American Welding Society and are noted as "ANSI/ AWS".
In engineering drawings, each weld is conventionally identified by an arrow which points to the joint to be welded. The arrow is annotated with letters, numbers and symbols which indicate the exact specification of the weld. In complex applications, such as those involving alloys other than mild steel, more information may be called for than can comfortably be indicated using the symbols alone. Annotations are used in these cases." [Symbols and conventions used in welding documentation. Wikipedia]
The example chart "Elements of welding symbol" is redesigned using the ConceptDraw PRO diagramming and vector drawing software from the Wikipedia file: Elements of a welding symbol.PNG.

This engineering drawing present weld type symbols and fillet weld symbols.
The weld type symbol is typically placed above or below the center of the reference line, depending on which side of the joint it's on. The symbol is interpreted as a simplified cross-section of the weld.
"Fillet welding refers to the process of joining two pieces of metal together whether they be perpendicular or at an angle. These welds are commonly referred to as Tee joints which are two pieces of metal perpendicular to each other or Lap joints which are two pieces of metal that overlap and are welded at the edges. The weld is aesthetically triangular in shape and may have a concave, flat or convex surface depending on the welder’s technique. Welders use fillet welds when connecting flanges to pipes, welding cross sections of infrastructure, and when fastening metal by bolts isn't strong enough." [Fillet weld. Wikipedia]

The vector stencils library "Bearings" contains 59 symbols of ball bearings, roller bearings, shafts, springs, gears, hooks, spindles, and keys.
Use it to design engineering drawings of machine tools and mechanical devices.
"A bearing is a machine element that constrains relative motion and reduce friction between moving parts to only the desired motion. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts. Many bearings also facilitate the desired motion as much as possible, such as by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts." [Bearing (mechanical). Wikipedia]

"Manufacturing is the production of goods for use or sale using labor and machines, tools, chemical and biological processing, or formulation. The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial production, in which raw materials are transformed into finished goods on a large scale.
Modern manufacturing includes all intermediate processes required for the production and integration of a product's components. Some industries, such as semiconductor and steel manufacturers use the term fabrication instead.
The manufacturing sector is closely connected with engineering and industrial design." [Manufacturing. Wikipedia]

The design elements library "Cable TV" contains 64 symbols of CATV network equipment.
"Cable television is a system of distributing television programs to subscribers via radio frequency (RF) signals transmitted through coaxial cables or light pulses through fiber-optic cables. This contrasts with traditional broadcast television (terrestrial television) in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television. FM radio programming, high-speed Internet, telephone service, and similar non-television services may also be provided through these cables.
The abbreviation CATV is often used for cable television." [Cable television. Wikipedia]
