泄漏测试的重要性（中英文）

泄漏测试是一种产品质量控制方法，通过对制造部件或系统泄漏进行孔隙度测试来识别制造过程中的不一致性。这种无损检测通常通过密封测试产品可能存在的任何端口或孔洞，然后将测试介质（通常是空气、氮气或氦气）引入测试件内部或周围来完成。然后，经过培训的操作员或泄漏测试仪器将能够观察到产品的任何泄漏。

泄漏测试可以在整个制造过程的各个阶段进行。许多原始设备制造商 (OEM) 要求在组装前对组件进行泄漏测试，以确保完整性。OEM 还可能在组装的不同阶段对整个系统进行泄漏测试，以确保为最终用户提供最佳、安全的产品。同样，在产品开发过程的不同阶段，可能会使用泄漏测试来对原型进行台架测试。本文将介绍实施泄漏测试流程时的重要注意事项，以及泄漏测试行业的一些主要趋势。

Leak testing is a method of product quality control that identifies manufacturing inconsistencies by porosity testing a manufactured part or system leaks. This non-destructive test is typically accomplished by sealing any ports or holes the test product might have and then introducing a test medium—usually air, nitrogen, or helium—into or around the test piece. From there, a trained operator or a leak test instrument will be able to observe any leaks coming into or out of the product.  

A leak test can be performed at various stages throughout the manufacturing process. Many original equipment manufacturers (OEMs) require that components be leak tested to ensure integrity before assembly. The OEM might also perform a leak test on the entire system during different stages of assembly to ensure an optimal, safe product for the end-user. Similarly, a leak test might be used at various times during a product development process to bench test prototypes. Throughout this post, we will cover important considerations when implementing a leak testing process, as well as some key trends in the leak testing industry.  

为何要进行泄漏测试？

Why Leak Test?

泄漏测试可验证制造的产品是否符合预定规格，从而确保部件或系统能够按预期运行。此过程对于确保产品质量和最终用户的安全至关重要。此外，可靠的泄漏测试流程有助于减少产品保修索赔，并降低系统制造商的质量成本。

优化泄漏测试流程还能带来多种生产效率优势。泄漏测试有助于验证供应商组件的质量，并确保操作员已正确组装系统组件。这样一来，制造商就能提高生产效率，避免返工和产品废品。FasTest 技术销售总监 Mark Spindler 表示：“如果在制造流程早期遗漏了泄漏，后期可能会造成很大的麻烦。想象一下，你正在组装一台 16 升的发动机，一切进展顺利，但是由于气缸盖垫片安装不正确，最终的泄漏测试失败了。隔离发动机、找出泄漏原因、拆卸系统并进行维修所浪费的时间是巨大的。”如果泄漏测试流程保持一致，制造商将能够使用泄漏测试对组装或组件故障进行根本原因分析，这将极大地改进整个制造流程，并减少以后测试失败的次数。

Leak testing provides verification that a manufactured product meets predetermined specifications that allow the part or system to operate as intended. This process is crucial to ensuring product quality and the safety of end-users. Additionally, a reliable leak testing process will help reduce product warranty claims and the cost of quality for systems manufacturers.  

There are also several production efficiencies benefits to an optimal leak testing process. A leak test will help validate supplier component quality and verify that operators have assembled system components correctly. In doing so, the manufacturer can improve production efficiency, and eliminate rework and product scrap waste. “If a leak is missed early on in the manufacturing process, it can cause significant headaches later,” says Mark Spindler, director of technical sales at FasTest. “Imagine you are assembling a sixteen-liter engine, everything is going well, but then the final leak test fails because the head gasket was not seated correctly. The amount of wasted time that goes into quarantining the engine, identifying the cause of the leak, disassembling the system, and repairing it, is enormous.”  If a leak testing process is consistent, manufacturers will be able to use leak tests to perform root cause analysis for assembly or component breakdowns, which will greatly improve the manufacturing processes as a whole and reduce the number of failed tests down the road. 

连接的重要性

The Importance of the Connection 

任何泄漏测试中最重要的方面是被测部件或系统上所有端口和孔的可靠、一致的防漏连接和密封。无论使用哪种泄漏测试，连接都至关重要；然而，制造商在开发泄漏测试流程时，连接环节常常被忽视。任何泄漏测试的目标都是隔离待测试的组件或系统，而这只有在所有测试端口和孔洞均密封且无泄漏的情况下才能实现。

如果没有适当的密封，泄漏测试很容易出现误报：即使被测部件本身无泄漏，泄漏测试也可能出现泄漏或失败。误报通常是由连接不当或密封不严引起的，这会导致介质渗入或渗出测试部件，从而导致测试失败。许多泄漏测试失败需要将部件报废或从生产线上移出重新测试。潜在的产品废品浪费和返工，以及工艺瓶颈问题，都至关重要。幸运的是，利用可靠的快速连接工具、可靠的密封和适当的索具可以轻松避免误故障。

The most important aspect of any leak test is a reliable, consistent leak-tight connection and seal for all ports and holes on the part or system being tested. This holds true regardless of the type of leak test being utilized; however, the connection is often overlooked when a manufacturer is developing their leak test process. The goal in any leak test is to isolate the component or system for testing, which can only be accomplished when all the test ports and holes are sealed and leak-tight.  

Without a proper seal, the leak test is prone to a false failure: leak tests that register a leak—or fail—when the part being tested is leak-free. A false failure is typically caused by an improper connection or profile seal, which allows media to seep into or out of the test part, resulting in a test failure. Many failed leak tests require the part to be scrapped or moved off the manufacturing line for retesting. The potential product scrap waste and rework, as well as process bottleneck considerations, are significant. Fortunately, false failures are easily avoided utilizing reliable quick connection tools, dependable sealing, and proper rigging. 

使用FasTest 连接工具是创建防漏密封的可靠、一致且高效的方法。这些连接工具经过精心设计，可与特定类型的端口、螺纹、管子或孔建立可重复的防漏连接。连接工具允许用户安全地进行必要的连接，以运行正确的泄漏测试，而无需担心误报或意外断开。这些设备通过将测试设置时间缩短高达 95%，减少产品废品和返工，并在不损坏测试件的情况下密封设备，显著提高了泄漏测试过程的效率。

泄漏测试趋势

Trends in Leak Testing 

工业 4.0 运动正在颠覆全球制造企业。拥抱工业 4.0 运动的企业的目标是以更低的成本生产产品，提高生产效率，并提供比落后竞争对手更优质的产品质量。在泄漏测试领域，工业 4.0 正在推动许多关键领域的变革，包括智能测试连接工具的兴起。

The industry 4.0 movement is disrupting manufacturing companies all over the world. The goal of companies that embrace the industry 4.0 movement is to produce goods at lower costs, drive throughput efficiencies, and provide superior output quality than lagging competitors. In leak testing, industry 4.0 is driving changes in many key areas including the rise of intelligent test connection tools. 

智能测试连接

Intelligent Test Connections 

为了收集更多工艺和泄漏测试数据，许多制造商开始依赖 FasTest ICON™ 连接工具。这些连接工具内置传感器，使泄漏测试流程管理人员能够收集数据并监控连接点的测试操作。FasTest 先进技术总监 Dustin Sirny 表示：“许多制造商通常希望获得更多数据，但更重要的是，他们希望获得可立即改进工艺的可操作数据。密封件位置等数据点可以帮助工艺工程师立即识别泄漏测试过程中的问题并采取具体的纠正措施。”

借助智能快速连接工具，用户可以确保在运行泄漏测试之前已正确建立连接，并且已成功隔离测试部件或系统。Sirny 表示：“我们已经看到许多制造商彻底改变了他们的泄漏测试方式，更重要的是，他们隔离制造部件的方式。智能测试连接还允许操作员监控连接工具磨损部件的健康状况，并优化维护计划，以避免代价高昂的停机。” 

随着工业 4.0 持续革新制造工艺和企业，泄漏测试方法也将随之演变。“泄漏测试市场几年来基本没有变化”Sirny 说道。“随着工业 4.0 的出现，我们十年来首次见证了泄漏测试的重大变化。我预计未来几年我们将看到泄漏测试流程和最佳实践的更多变化。”

To help gather more process and leak testing data, many manufacturers have begun relying on FasTest ICON™ Connection Tools. These Connection Tools have incorporated sensors that allow leak test process managers to collect data and monitor testing operations at the point of connection. “Many manufacturers want more data to work with in general, but more importantly they want actionable data that can improve their processes immediately,” says Dustin Sirny, director of advanced technologies at FasTest. “Data points such as seal placement can help process engineers immediately identify problems in the leak testing process and take specific corrective actions.” 

With smart quick connection tools, users can ensure that the proper connections have been made and that the test part or system has been successfully isolated before running a leak test. “We’ve seen many manufacturers completely transform the way they are leak testing, and more importantly how they are isolating their manufactured part”, said Sirny. “Intelligent test connections also allow operators to monitor the health of the connection tool’s wear components and optimize maintenance schedules to avoid costly downtime.” 

As Industry 4.0 continues to revolutionize manufacturing processing and companies, leak testing methods will also evolve. “The leak testing market went largely unchanged for several years,” said Sirny. “With the emergence of Industry 4.0, we are seeing major changes in leak testing for the first time in a decade. I expect that we will see many more changes to the leak testing process and best practices in the coming years.”
