真空制动器, 真空制动系统
a braking system that uses suction to apply brakes, commonly found in older railway systems
A vacuum brake is a type of braking system used on some trains, which operates by creating a vacuum, a space with low air pressure, to activate the brakes. The vacuum is created in a chamber and, when applied, causes a valve to open, which allows brake pads to press against the wheels, slowing the train down. This system was widely used in the past, especially on older trains, but has been mostly replaced by air brakes in modern rail transport due to the greater reliability and power of air brake systems. Despite this, vacuum brakes are still found on some older or preserved trains.
- Trains equipped with a vacuum brake system rely on air pressure differences to slow down and stop the locomotive.
配备真空制动系统的火车依靠气压差来减速和停止机车。
- The vacuum brake became a standard feature in railways during the 19th century, improving safety and efficiency in train operations.
真空制动器在19世纪成为铁路的标准配置，提高了列车运行的安全性和效率。
- When the vacuum brake is engaged, it creates a vacuum in the braking system's pipes, allowing atmospheric pressure to push brake blocks against the wheels.
当真空制动器启动时，它会在制动系统的管道中产生真空，使大气压力将制动块推向车轮。
- Maintenance of the vacuum brake system requires specialized knowledge and regular checks to ensure optimal performance.
真空制动系统的维护需要专业知识和定期检查以确保最佳性能。
- Modern trains have largely replaced vacuum brakes with more advanced air or electronic braking systems for enhanced reliability and control.
现代火车已经很大程度上用更先进的空气或电子制动系统取代了真空制动器，以提高可靠性和控制性。
