Mechanical Drawing Symbols

Mechanical Drawings are the special type of technical diagrams that visualize the structure of complex systems and illustrate the information about ventilation, heating, air conditioning, i.e. HVAC systems. These drawings are created on the base of floor plans and reflected ceiling plans, and then become an obligatory part of construction project which is needed directly for construction a building and for receiving a permit on it. Mechanical drawings and diagrams help effectively represent construction, technical and engineering solutions, and also schematics of different mechanical equipment. ConceptDraw DIAGRAM ector drawing software enhanced with Mechanical Engineering solution from Engineering area of ConceptDraw Solution Park provides wide set of effective drawing tools, predesigned mechanical drawing symbols, templates, samples and examples. Use of standardized and recognized mechanical vector symbols helps you design understandable mechanical drawings, diagrams and mechanical engineering schematics.

Elements location of a welding symbol

"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]

Design elements - Dimensioning and tolerancing

The vector stencils library "Dimensioning and tolerancing" contains 45 symbols of geometric dimensions and mechanical tolerances, geometric symbols, callouts, and text boxes and inserts.
Use these geometric dimensioning and tolerancing (GD&T) shapes to create annotated mechanical drawings.
"Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances. It uses a symbolic language on engineering drawings and computer-generated three-dimensional solid models that explicitly describes nominal geometry and its allowable variation. It tells the manufacturing staff and machines what degree of accuracy and precision is needed on each controlled feature of the part. GD&T is used to define the nominal (theoretically perfect) geometry of parts and assemblies, to define the allowable variation in form and possible size of individual features, and to define the allowable variation between features."

Welding symbols

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 "Valve assembly" contains 141 symbols of pressure and flow regulators, flow direction indicators, controls, and symbols to design flow paths of control valves.
Use these valve assembly shapes to design the engineering drawings of hydraulic and pneumatic valve assemblies in fluid power systems.
"Control valves are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a "setpoint" to a "process variable" whose value is provided by sensors that monitor changes in such conditions.
The opening or closing of control valves is usually done automatically by electrical, hydraulic or pneumatic actuators. Positioners are used to control the opening or closing of the actuator based on electric, or pneumatic signals.
A control valve consists of three main parts in which each part exist in several types and designs: Valve's actuator, Valve's positioner, Valve's body.

Design elements - Bearings

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]

Design elements - Hydraulic pumps and motors

The vector stencils library "Hydraulic pumps and motors" contains 74 symbols of hydraulic pump vector stencils, hydraulic motor symbols for engineering drawings of fluid power and hydraulic control systems.
"Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic.
Hydrostatic pumps are positive displacement pumps while hydrodynamic pumps can be fixed displacement pumps, in which the displacement (flow through the pump per rotation of the pump) cannot be adjusted, or variable displacement pumps, which have a more complicated construction that allows the displacement to be adjusted." [Hydraulic pump. Wikipedia]
"A hydraulic motor is a mechanical actuator that converts hydraulic pressure and flow into torque and angular displacement (rotation). The hydraulic motor is the rotary counterpart of the hydraulic cylinder.
Conceptually, a hydraulic motor should be interchangeable with a hydraulic pump because it performs the opposite function - much as the conceptual DC electric motor is interchangeable with a DC electrical generator. However, most hydraulic pumps cannot be used as hydraulic motors because they cannot be backdriven. Also, a hydraulic motor is usually designed for the working pressure at both sides of the motor.
Hydraulic pumps, motors, and cylinders can be combined into hydraulic drive systems. One or more hydraulic pumps, coupled to one or more hydraulic motors, constitutes a hydraulic transmission." [Hydraulic motor. Wikipedia]

Design elements - Pneumatic pumps and motors

The vector stencils library "Pneumatic pumps and motors" contains 39 symbols of pneumatic pumps, motors and pump-motors for designing the engineering drawings of pneumatic circuits.
"A pneumatic motor or compressed air engine is a type of motor which does mechanical work by expanding compressed air. Pneumatic motors generally convert the compressed air energy to mechanical work through either linear or rotary motion. Linear motion can come from either a diaphragm or piston actuator, while rotary motion is supplied by either a vane type air motor or piston air motor." [Pneumatic motor. Wikipedia]
"A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. An air compressor is a specific type of gas compressor.
Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible; while some can be compressed, the main action of a pump is to pressurize and transport liquids." [Gas compressor. Wikipedia]
