The PN2Z-G.70-20-200 is a high-performance double-acting cylinder specifically developed for the railway industry. It is ideally suited for critical railway equipment scenarios such as turnout switching, vehicle braking, and signal execution. With its durability and stability in extreme railway operating conditions, it has become one of the core components for improving the continuous operation capability of railway equipment.
High wear resistance
Railway equipment is exposed to dusty, high-frequency vibration outdoor environments for extended periods. The cylinder barrel of this cylinder uses a special wear-resistant coating material, which can effectively resist wear caused by the intrusion of metal particles and sand and dust. The wear rate is lower than that of ordinary cylinders, which can reduce the frequency of equipment downtime for maintenance.
Shock and vibration resistance
The vibrations during railway line operation and the impacts of vehicle start-stop are quite strong. The cylinder is equipped with reinforced end caps and a buffer structure, which can stably maintain the thrust output accuracy under the high-frequency impact conditions of the turnout actuator, avoid action failure caused by vibration, and ensure the continuous and reliable operation of the railway signaling system.
Wide Temperature Adaptability
Railway equipment needs to withstand temperature differences from -30℃ (high-altitude cold regions) to 50℃ (summer high temperatures). The cylinder seals adopt a multi-sealing structure resistant to high and low temperatures, which can maintain zero leakage sealing performance in the turnout drive scenario along high-altitude cold railway lines, adapting to the all-weather operation requirements of railway environments in all regions.
Modular Installation
The cylinder adopts a modular design, which can be directly matched with the standard railway equipment interfaces of turnouts and braking systems, without the need for additional customized brackets. This significantly improves the operation and maintenance efficiency of railway equipment and reduces the total life cycle operation and maintenance cost.
Railway turnout switching system: A turnout switching mechanism adapted to railway mainlines and stations, which acts as an actuator to drive the precise switching of turnout switch rails and ensure the stability of track direction changes.
Railway vehicle braking auxiliary device: used in the braking system of passenger and freight trains, as a pneumatic actuator in conjunction with the pipeline to achieve rapid response of braking components and improve the braking safety of vehicle operation.
Track maintenance equipment power unit: As the actuator of the track fastener tightening and loosening equipment, it provides stable thrust in daily track maintenance operations and improves the efficiency of fastener operation and maintenance.
Is it convenient to replace this cylinder during emergency repairs at railway sites?
Yes, it supports rapid replacement. The cylinder uses standardized interfaces and a modular structure typical of railway equipment. Maintenance personnel only need basic tools such as wrenches to quickly disassemble and reassemble it, perfectly meeting the efficiency requirements of emergency repairs at railway sites.
Does it require special treatment when used in frigid northern regions?
No special treatment is needed. This cylinder has passed a -30°C low-temperature test and can be used directly in frigid northern regions. Preheating is recommended before use in extremely cold conditions (below -25°C) to ensure optimal performance.
