Nowadays, when it comes to the face of Chinese railroads, it is the "Fuxing", with its slender streamline shape, industrial quality silver-gray body and "golden phoenix" shape, which has amazed countless passengers. It is not only high value, but also fast, a minute can be forward 5833 meters, more valuable is that in the high-speed operation of the state, the brake is still accurate and smooth. This is inseparable from the excellent performance of the braking system.
The role of the braking system is to control the safe stopping of the vehicle. For a high-speed train, the importance of the braking system is beyond doubt, and every component must be highly reliable. In fact, EO tube coupling is only one of the EO series couplings from Parker Hannifin, and the EO series coupling family is well known in the rail industry for many years. "The EO-2 series is another important member of the EO family - the EO-2 series coupling.
Based on Ermeto ferrule system design
The EO-2 series couplings are based on the well-known Ermoto ferrule system and feature a large volume elastomeric seal that is invisible from the outside but maintains long-lasting functionality and sealing performance under extreme application conditions. The sealing effect is supported by the system pressure and is suitable for high pressure applications. Due to the high preload of the seals, the EO-2 series couplings are designed with a strong gas-tight seal that prevents air penetration in a vacuum. Compared to other coupling types, EO-2 Series couplings have no gap construction, preventing common seal damage such as spiral crush or wear caused by the "pulse effect".
Avoiding under- and over-assembly
Under- and over-assembly is a common problem in fitting installation, but not in EO-2 series fittings. Prior to assembly, there is a gap between the seal and the end face of the locating ring. Once the ring reaches the final cut-in depth of the pipe, the gap closes, indicating that the assembly is complete, and the same result can be obtained with manual assembly. The operator can visually confirm that the assembly is complete.
EO2-2 improves assembly safety
Once the gap between the two rings is closed, the assembly check and final installation of the EO-2 series fitting can begin. Simply tighten the function nut with a wrench and twist it 1/4 to 1/6 turn. This stopping point is obvious, i.e. it increases the safety of the user and effectively prevents dangerous situations of under-assembly. Always remember this: "Turn to the stop and you're done", the EO-2 connector is designed to be so user-friendly.
Conformity with international standards
The EO-2 series couplings comply with DIN 2353 and ISO 8434 standards. They are suitable for steel pipes with an outside diameter of 6 - 42 mm and cover most applications up to 200°C. Of course, they are also suitable for use in the Arctic. The EO-2 series couplings are available in carbon steel or stainless steel, so you can choose for your specific application. All EO-2 series couplings are certified to EN45545-2 and EN61363, and are also IRIS certified. For designers, this means a wide selection of fittings that meet international standards, simplifying design and reducing procurement requirements.
EO2-3 is easy to assemble for a wide range of applications
The EO-2 series couplings cover a wide range of applications, including hydraulic and pneumatic applications. For the user, the EO-2 series couplings offer cost savings and reduced workload. In addition, the EO-2 series coupling series is suitable for installation in extremely limited spaces. eO-2 series couplings are well lubricated and easy to assemble. Threads over size 25S/28L are additionally lubricated with EO-LU. As a result, the torque of EO-2 series couplings is reduced by approximately 25%, helping to prevent under-assembly situations.
Savings in procurement and storage costs
The EO-2 function nut assembles the seal and locating ring together, and the three are combined into one design element, thus avoiding missing, mixing, or installing individual components such as seals and ferrules in the wrong way. The individual components can also be easily brought together during assembly, thereby reducing assembly time, reducing storage costs and improving system safety. As a whole, the EO-2 series couplings can help you reduce overall costs and are safe and reliable as an alternative to similar coupling systems.
