pneumatic
의미: Operated by or involving compressed air or gas. Pneumatic tools and systems use air pressure to transmit force.
Pneumatic systems are the air-powered counterpart of hydraulic systems. They are widely used in factories, construction sites, and workshops — pneumatic drills (jackhammers), nail guns, and spray guns are common examples. Pneumatic systems are generally lighter and cleaner than hydraulic ones, though they cannot generate as much force. The word is pronounced with a silent 'p' (new-MAT-ik), which frequently trips up learners.
예문
- The construction workers used a pneumatic drill to break up the old concrete pavement. 建筑工人使用气动钻来破碎旧混凝土路面。Los obreros utilizaron un martillo neumático para romper el viejo pavimento de hormigón.建設作業員は古いコンクリート舗装を砕くために空気圧ドリルを使用しました。건설 작업자들은 오래된 콘크리트 포장을 부수기 위해 공압 드릴을 사용했습니다.
- Pneumatic systems are preferred in food processing because, unlike hydraulic systems, a leak will not contaminate the product. 气动系统在食品加工中更受青睐,因为与液压系统不同,泄漏不会污染产品。Los sistemas neumáticos se prefieren en el procesamiento de alimentos porque, a diferencia de los hidráulicos, una fuga no contamina el producto.空気圧システムは食品加工で好まれます。油圧システムとは異なり、漏れが発生しても製品を汚染しないからです。공압 시스템은 식품 가공에서 선호됩니다. 유압 시스템과 달리 누출이 발생해도 제품을 오염시키지 않기 때문입니다.
- The factory's assembly line relies on pneumatic actuators to position components with speed and precision. 工厂的装配线依赖气动执行器来快速精确地定位零部件。La cadena de montaje de la fábrica depende de actuadores neumáticos para posicionar los componentes con rapidez y precisión.工場の組立ラインは、部品を迅速かつ精確に配置するために空気圧アクチュエータに依存しています。공장의 조립 라인은 부품을 신속하고 정밀하게 배치하기 위해 공압 액추에이터에 의존하고 있습니다.
