Reading fluids circuit diagrams - hydraulic & pneumatic symbols

Below are some common illustrations of equipment located on fluids circuit diagrams, followed by descriptions of the most common elements. Later in this article series we will describe some simple hydraulic and pneumatic circuits composed of these circuit elements. Needle valves are used to throttle or shut-off flow of fluids. They usually will vary flow with pressure or viscosity change. Gauges are used to measure the oil pressure at a given point in the system. This is usually measured in PSI or bars.

Pneumatic & Hydraulic : Symbols

Electrical 2 windings Electrical control with two windings, two directions. Electrical 2 windings. Electrical control with two windings, two dir, variable. One closed direction. Restrictor V. Valve normally closed in unactivated position. Pressure control.


Pneumatic symbols conform to and are devised f th I t ti l St d d ISO 1 Through the 18 national associations which are member of CETOP, all well known.


Schematic Symbols Chart (Design Hydraulic and Pneumatic circits)

Circular -large circle - pump, motor -small circle - Measuring devices -semi-circle - rotary actuator Square -one square - pressure control function -two or three adjacent squares - directional control Diamond Miscellaneous Symbols -diamond - Fluid conditioner filter, separator, lubricator, heat exchanger -Spring -Flow Restriction Triangle -solid - Direction of Hydraulic Fluid Flow -open - Direction of Pneumatic flow Pumps and Compressors turn rotary torque from an AC or DC electric motor into pressure in a hydraulic or pneumatic system Fixed Displacement hydraulic pump. Proportional Pressure Relief - line pressure is limited to and proportional to an electronic signal Sequence Valve - when the line pressure reaches the setting of the valve, valve opens permitting flow to the secondary port. The pilot must be externally drained to tank. Pressure Reducing valve - pressure downstream of valve is limited to the setting of the valve Flow Control Valves Throttle valve Flow Control valve -adjustable output flow -with fixed output variations in inlet pressure do not affect rate of flow -with fixed output and relief port to reservoir with relief for excess flow variations in inlet pressure do not affect rate of flow -with variable output -fixed orifice -metered flow toward right free flow to left -pressure compensated flow control fixed output flow regardless of load -pressure and temperature compensated Flow dividing valve -with variable output and relief port to reservoir -flow is divided equally to two outputs.

Fluid power diagrams and schematics require an independent review because they use a unique set of symbols and conventions.

Прошу меня извинить. К человеку в моем положении часто приходят с… ну, вы понимаете. - Да, мистер Клушар, конечно, понимаю. Это цена, которую приходится платить за известность. - Действительно.  - Клушар вздохнул с видом мученика, вынужденного терпеть всякий сброд.  - Вы когда-нибудь видели что-либо более ужасное, чем это место? - Он обвел глазами палату.

Еще здесь был вещевой мешок, который полиция взяла в отеле, где остановился этот человек.

Сьюзан еще раз перечитала послание Танкадо. Главная разница между элементами… разница между… нужно найти число… - Подождите! - сказала.  - Слово разница многозначно. Нам нужно число - значит, речь идет о математике. Еще одна игра слов мистера Танкадо: разница означает результат вычитания.

 Он работает на Монокле, - пояснил Смит.  - Посылает сообщение о том, что Танкадо ликвидирован. Сьюзан повернулась к Беккеру и усмехнулась: - Похоже, у этого Халохота дурная привычка сообщать об убийстве, когда жертва еще дышит. Камера последовала за Халохотом, двинувшимся в направлении жертвы.

Сорокадвухлетний португальский наемник был одним из лучших профессионалов, находящихся в его распоряжении. Он уже много лет работал на АНБ. Родившийся и выросший в Лиссабоне, он выполнял задания агентства по всей Европе.
