Accurate leak detection, safeguarding every drop of purity - Upgrading guide for leak detection technology of household water purifiers
Date: 2025-11-26Read: 2
With the rapid development of urbanization and industrialization, water pollution has become increasingly severe, and safe drinking water has become a focus of attention for every household. The decline in the quality of drinking water in Quanqiu has driven the popularization of household water purification equipment - not only due to the awakening of consumer health awareness, but also driven by increasingly strict health and water safety standards.
In this context,Water purifier manufacturers are facing higher product reliability requirementsButLeak detection, as a critical link in production and quality control, is particularly importantEven minor leaks can affect equipment performance, cause malfunctions, and even lead to after-sales issues.
This article will introduce how to use modern high-sensitivity leak detection technology to accurately identify micro leaks in the early stages, thereby ensuring the long-term operation of products and improving user satisfaction.
The limitations of traditional leak detection methodsA typical household water purifier typically includes 3 to 5 filter cartridges, quick couplings, and plastic piping.In the traditional quality inspection process, water injection and pressure testing are often used. The components are placed on absorbent paper to observe whether there is water seepage. The entire process takes about 15 minutes, followed by a pressure test of about 4-5 bar.
For whole machine inspection, common methods include:
Water bath test: immerse the device under pressure in water and observe if any bubbles emerge;
Soap water test: Spray soap solution on the joints and connections, wait for 2-5 minutes for the bubbles to dissipate, and visually inspect for any bubbles.
Although simple to operate, these methods are time-consuming and rely on the experience of operators, making it difficult to detect micro leaksThis ultimately leads to problems with the product in actual use. In addition,The cleaning and drying process after testing can also easily cause congestion on the production lineIt affects efficiency.
Moving towards more precise and efficient leak detectionTo address the above challenges, the industry is gradually shifting towards more standardized and quantifiable leak detection solutions. among which,Using a mixed gas (such as containing 5% hydrogen and 95% nitrogen)astracer gasThe method has become a modern and efficient new choice.
This technology mainly consists of three steps:
1.Vacuum pumping:Remove residual air and moisture inside the equipment;2.Filling tracer gas:Inject a specific proportion of mixed gas;3.Detection and positioning:Use sniffing probes in conjunction with professional detectors to accurately scan and quantify leakage points.
This method not only significantly improves detection accuracy, but also avoids reliance on manual judgment, significantly improving quality inspection efficiency.
Why choose tracer gas leak detection?Compared with traditional methods, tracer gas detection has multiple advantages:
Quickly locate the leak location without relying on manual experience;Provide objective and quantifiable leaked data;Only repair leakage points that exceed the standard to reduce unnecessary rework;No need to clean or dry, saving time and space;Effectively prevent production line backlog and improve overall production efficiency.
INFICON's tracer gas leak detector is designed specifically for complex components such as multi-stage water purification systems, providing fast, accurate, and reproducible test results to help manufacturers improve product reliability while reducing scrap rates and rework costs.
