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.

Design elements - Fluid power equipment

The vector stencils library "Fluid power equipment" contains 113 symbols of hydraulic and pneumatic equipment including pumps, motors, air compressors, cylinders, meters, gauges, and actuators. Use it to design fluid power and hydraulic control systems.
"Fluid power is the use of fluids under pressure to generate, control, and transmit power. Fluid power is subdivided into hydraulics using a liquid such as mineral oil or water, and pneumatics using a gas such as air or other gases. Compressed-air and water-pressure systems were once used to transmit power from a central source to industrial users over extended geographic areas; fluid power systems today are usually within a single building or mobile machine." [Fluid power. 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 - Fluid power valves

The vector stencils library "Fluid power valves" contains 93 symbols of pre-made hydraulic and pneumatic valves, including directional control valves, flow control valves, pressure control valves, and electrohydraulic and electropneumatic valves.
"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.

Pneumatic 5-ported 3-position valve template - Mac

"Directional control valves are one of the most fundamental parts in hydraulic machinery as well and pneumatic machinery. They allow fluid flow into different paths from one or more sources. They usually consist of a spool inside a cylinder which is mechanically or electrically controlled. The movement of the spool restricts or permits the flow, thus it controls the fluid flow. ...
While working with layouts of hydraulic machinery it is cumbersome to draw actual picture of every valve and other components.instead of pictures symbols are used for variety of components in the hydraulic system to highlight the functional aspects. symbol for directional control valve is made of number of square boxes adjacent to each other depending on the number of positions.connections to the valve are shown on these squares by capital letters.usually they are named only in their normal position and not repeated in other positions.actuation system of the valve is also designated in its symbol."
