Analysis of frequently asked questions about air tightness testing: What should I do if a problem occurs?
Air tightness testing plays a vital role in various industrial and manufacturing processes.Whether it is automobile manufacturing, home appliance production or aerospace, air tightness testing can ensure that products will not leak during use and ensure safety and performance.However, precisely because of its importance, various problems are inevitable in actual operation.How to deal with these problems has become a big challenge.As the industry's leading supplier of air tightness testing equipment, Hirays will provide you with a detailed analysis of eight common problems and solutions during the air tightness testing process.From subtle leak detection to complex system failures, we strive to help you solve problems one by one and protect your production.
Whether you are new to air tightness testing or a veteran, this article will provide you with practical information and valuable insights.If you are having trouble using air tightness testing equipment, this article is undoubtedly your best guide.Are you ready?Let’s find out!
1. Test results fluctuate greatly
If your test results frequently fluctuate, you first need to check the stability of your test environment.Changes in temperature and humidity often affect test results.Air movement is also an important factor, and if the air movement around the test equipment is too strong, it may cause the results to fluctuate too much.The best solution is to ensure the stability of the test environment.Consider adding a dedicated testing room to maintain constant temperature and humidity.
Alternatively, the calibration of the device itself may be the source of the problem.It is critical to calibrate equipment regularly to ensure its accuracy.If the equipment has not been calibrated for a long time, problems are inevitable.Don't ignore the proficiency of the operator. A skilled operator can effectively reduce human errors.
2. The test time is too long
Long test times are another common problem, especially if high-volume production is required.The extension of test time will not only affect production efficiency, but also increase costs.There may be many reasons for this, such as unreasonable testing procedures, delayed leakage detection valves, etc.
Optimizing test procedures is the key to solving this problem.For example, re-evaluate the necessity of each test step and eliminate unnecessary steps.You can also consider using higher-speed detection equipment to increase detection speed.Hirays provides a series of high-efficiency air tightness testing equipment, which can significantly shorten testing time and make your production line more efficient.
3. Equipment leaks
Air leakage problems in the equipment itself also occur from time to time.This may be caused by the device's seals being old, damaged, or improperly installed.If you suspect a leak in your equipment, the first step is to conduct a comprehensive equipment inspection.
Carefully inspect each sealing part of the equipment to see if there are any obvious cracks or signs of wear.If the seal is found to be aged or damaged, it should be replaced in time.When installing the seal, make sure it is installed in place to avoid air leakage problems caused by improper installation.
4. Insufficient vacuum
Insufficient vacuum is a common problem when performing vacuum testing.This may be due to a poor vacuum pump performance, a leaking line, or a problem with the test vessel itself.Check the working status of the vacuum pump to ensure it is operating normally.
If there is no problem with the vacuum pump, you can check the vacuum line for leaks.The method is to immerse part of the pipeline in water and observe whether there are bubbles emerging.If a pipeline leak is found, it should be repaired or replaced in time.Inspect the test container itself to make sure it is free of cracks and leaks.
5. Unable to detect small leaks

Detecting small leaks is a major difficulty in air tightness testing.Usually, this problem is caused by insufficient sensitivity of the test equipment or improper test methods.Consider using higher sensitivity test equipment.For example, the high-precision leak detector provided by Hirays can easily detect small leaks.
It is equally important to ensure that the test environment is clean and stable.Some dust, impurities, etc. may interfere with the test results.Before conducting the test, ensuring that the object being tested and the test environment are clean can improve the accuracy of the test.
6. Insufficient operators
Although modern air tightness testing equipment is increasingly automated, the training and number of operators are still important factors affecting test quality.Insufficient operators or insufficient training can lead to unstable test results and even misjudgments.
The key to solving this problem is to strengthen the training of operators to ensure that they are proficient in equipment operation and testing procedures.Formulating detailed operating procedures and conducting regular training and assessments can effectively improve the skills and responsibility of operators.
7. High error
Excessive test error is another common problem, often caused by inaccurately calibrated equipment or problems with the test method.Regular calibration of test equipment is key to ensuring test accuracy.Different testing methods may bring different testing results.
When conducting air tightness testing, selecting appropriate testing methods and instruments and adjusting them according to the actual situation can effectively reduce testing errors.Hirays' air tightness testing equipment is equipped with a variety of test modes and accuracy options to meet different testing needs.
8. Data management is confusing
In a high-volume production environment, how to effectively manage and analyze test data is a challenge.Recording and analyzing data manually is not only time-consuming and labor-intensive, but also error-prone.The use of automated data management systems is an effective way to solve this problem.
Hirays provides a complete set of data management solutions, which can realize real-time data collection, storage and analysis through network interfaces and professional software, helping you better manage test data and improve production efficiency.
in conclusion
In general, although the problems in air tightness testing are diverse, they can all be solved with appropriate methods and equipment.Whether it is environmental factors, equipment issues or operator skills, they all need to be fully considered and adjusted.With proper optimization and training, you can greatly improve the efficiency and accuracy of your air tightness testing.
