7 Difference Between Hydraulics and Pneumatic

Practically every industrial process requires objects to be moved, manipulated, or be subjected to some form of force. This is generally accomplished by means of electrical equipment such as motors or solenoids , or via devices driven by air pneumatics or liquids hydraulics. Traditionally, pneumatics and hydraulics are thought to be a mechanical engineer's subject and are generally taught as such in colleges. In practice, techniques and, more important, the faultfinding methodology tend to be more akin to the ideas used in electronics and process control. This book has been written by a process control engineer as a guide to the operation of hydraulic and pneumatic systems.

Introduction to Hydraulics and Pneumatics

Hydraulic and pneumatic devices are all around us. They're used in manufacturing, transportation, earthmoving equipment and common vehicles we see every day. The brakes on your car are hydraulically operated; the garbage truck that passes weekly by your house uses hydraulic power to compact trash. Your mechanic uses a hydraulic lift when working on the underside of your car. Pneumatic systems are equally widespread.

Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically-powered compressor powers cylinders , air motors , pneumatic actuators , and other pneumatic devices. A pneumatic system controlled through manual or automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer alternative to electric motors and hydraulic actuators. Pneumatics also has applications in dentistry , construction , mining , and other areas. Pneumatic systems in fixed installations, such as factories, use compressed air because a sustainable supply can be made by compressing atmospheric air. The air usually has moisture removed, and a small quantity of oil is added at the compressor to prevent corrosion and lubricate mechanical components. Factory-plumbed pneumatic-power users need not worry about poisonous leakage, as the gas is usually just air.

Most companies spend a great deal of money training their maintenance personnel so that they can troubleshoot and correct failures of a hydraulic system. If the focus was shifted to the prevention of system or component failures, less time and money could be spent on troubleshooting. We normally expect hydraulic system failure, rather than deciding not to accept hydraulic failure as the norm.

Hydraulics and pneumatics will be a familiar topic for you. The major difference between these two power transferring technique is the medium used. For hydraulics, incompressible fluids are used and for pneumatics, compressed gases are used. The article Hydraulics and Pneumatics will be one useful article if you want to study the difference between these. In general, hydraulic systems are used for precise controlling of large force applications and pneumatic systems for lightweight and speedy applications. Hydraulic-based components are made using steel and pneumatic components are made using plastics and non-ferrous materials.

ГЛАВА 59 Сьюзан протянула руку, и коммандер Стратмор помог ей подняться по лестнице в помещение шифровалки. А перед глазами у нее стоял образ Фила Чатрукьяна, его искалеченного и обгоревшего тела, распростертого на генераторах, а из головы не выходила мысль о Хейле, притаившемся в лабиринтах шифровалки. Правда открылась со всей очевидностью: Хейл столкнул Чатрукьяна. Нетвердой походкой Сьюзан подошла к главному выходу- двери, через которую она вошла сюда несколько часов. Отчаянное нажатие на кнопки неосвещенной панели ничего не дало: массивная дверь не поддалась.

А я-то думал, что ты будешь это отрицать. - Подите к черту. - Очень остроумно. - Вы болван, Стратмор, - сказал Хейл, сплюнув.  - К вашему сведению, ваш ТРАНСТЕКСТ перегрелся.

Прошу меня извинить. К человеку в моем положении часто приходят с… ну, вы понимаете.

Стратмор кивнул: - Это наименьшая из наших проблем. - Не можем ли мы подкупить Танкадо. Я знаю, он нас ненавидит, но что, если предложить ему несколько миллионов долларов. Убедить не выпускать этот шифр из рук. Стратмор рассмеялся: - Несколько миллионов.

Ровно год назад он разбил здесь себе голову. Сегодня годовщина. Беккер кивнул, плохо соображая, какая тут связь. - Такая прическа была у Табу в день гибели.  - Парень снова сплюнул.

 Понятно. Она получит ваше письмо утром. - Спасибо, - улыбнулся Беккер и повернулся, собираясь уходить.
