Reliable automation despite continuous load

For HYTRON, the equipment previously used in the PSA process required a high level of maintenance. Conventional ball valves with welded ends couldn’t withstand the extreme load conditions. This resulted in wear, leakages, and costly downtime. Each repair involved cutting, re-welding, and this led to production stops in a process designed for continuous operation. The goal was to have a system that could withstand these stresses, would need fewer interventions, and would still meet all explosion protection standards.

To replace the existing setup, we supplied angle seat valves with a longer service life compared to other valves and flanged connections that eliminate the need for cutting or welding during maintenance.

Pneumatic actuation is provided by an Ex-certified automation system with a valve terminal CPX/MPA which integrates communication, control, and monitoring components into a compact cabinet. This design provides precise control and consistent switching performance. The process now runs smoothly and reliably, even with hundreds of thousands of switching cycles per year.

借助 Festo AX，在问题发生前防患于未然

为进一步减少停机时间，控制系统增设了数字监控功能。 现在，可通过 Festo AX Motion Insights Pneumatic 应用持续分析来自 PSA 系统的数据（包括阀门动作及切换频次）。 该系统能及早检测行为偏差，并在磨损导致故障前提示需要进行维护。 对 Neuman & Esser 而言，这意味着减少非计划性干预、延长设备运行时间，并能全面掌握每个组件的运行状态。 传统维护转变为可预测、数据驱动的流程，能切实提升可靠性和效率。 更多详情请阅读我们的博客文章。

联合开发，共筑未来

Neuman & Esser 与 Festo 的工程团队紧密合作，共同开发了这套解决方案。 防爆设计的每一个组件都经过实际工况下的测试、优化与验证。 开发周期得以缩短，最终形成的解决方案如今已成为未来氢能应用领域 PSA 项目的参考范本。 得益于其模块化架构，该方案可轻松适配其他系统与工艺，从而为氢能全价值链中安全、数字化互联的自动化提供可扩展的基础。
