Hai Ruisi will reveal the secret to you: the "magic" and "worry-relief" of the air tightness tester

Imagine that you just bought a waterproof mobile phone and threw it into the water with great joy. As a result, the screen bubbled up. This was not because the phone was saying hello to you, but because there was a big problem with the sealing!According to statistics, the global product repair rate due to sealing defects is as high as 15% every year, which means that out of every 100 products, 15 may drive you crazy.The air tightness tester is the "behind-the-scenes hero" who silently protects product quality.Today, Haireisi takes you into the world of air tightness testers and talks about its working principles and solutions to common troublesome problems.Whether you are a factory owner or a DIY enthusiast, this guide will definitely help you avoid detours and even save some repair costs!Are you ready?Let’s “debunk” its secrets together!

How does an air tightness tester “sniff out” air leaks?

The working principle of the air tightness tester sounds like a science fiction movie, but it is actually as simple as blowing up a balloon.Have you ever tried to inflate a balloon and then pinch the opening to see if it leaks?That’s what an air tightness tester does, except it’s smarter and more precise.Hirays' air tightness tester uses compressed air to "inflate" the product, and then monitors pressure changes through precision sensors.If the pressure drops quickly like a deflated rubber ball, it means there is a leak; if it is as stable as a rock, it means the sealing is up to standard.This "pressure drop method" is the mainstream method in the industry, it is simple, crude and reliable.For example, when testing an automobile part, the instrument will increase the pressure to a specified value within a few seconds, and then stare at the pressure gauge "without blinking an eye." Once an abnormality is discovered, an alarm will be issued immediately.Doesn’t he sound like a meticulous detective?

Of course, Hai Ruisi's equipment also has a "unique skill" - positive and negative pressure switching test.Negative pressure means air extraction, which pulls air out like a vacuum cleaner. It is suitable for testing vacuum-sealed products.Imagine that you want to test the tightness of a thermos cup to ensure that it does not leak. Just pumping air in is not enough. You have to "suck" it in reverse.This flexibility makes Tansuo's testers very popular in the automotive, electronics, and even aviation fields.What are the user pain points?Many people think that air-tightness testing is just a matter of blowing casually. In fact, accuracy and stability are the key. Otherwise, if a small gap is missed, the product will become a "ticking time bomb" after it goes online.So, don’t underestimate this machine, it is the “goalkeeper” of quality!

Why are my test results always "erratic"?

Have you ever encountered this situation: the same product passed the test yesterday, but leaks today, making you doubt your life?This is not because the instrument is kidding you, but because something is wrong with the operating environment or settings.Haris engineers often receive such "help calls": users say that the test results are like riding a roller coaster, sometimes high and sometimes low.In fact, the "little goblins" of temperature and humidity may be the culprit.For example, when the temperature in the workshop is high, the air expands, and the pressure value may "dance"; when the humidity is too high, the seals become damp, and air leakage is more likely to be amplified.For example, a customer tested a mobile phone case, and the results were unstable every afternoon. Later, it was discovered that the problem was caused by temperature changes caused by the air conditioner nearby blowing directly onto the equipment.

There is another common problem: parameter settings are not “intimate” enough.The air tightness tester needs to set the inflation time, stabilization time and test time, but novices are often confused and just fill in the numbers and start working.The result?If the inflation time is too short, the pressure has not yet stabilized; if the stabilization time is not enough, the data will be measured before you can "take a breath".Haris's suggestion is to run once with the default values ​​and then fine-tune according to the pressure curve.For example, when testing a kettle lid, set the inflation setting for 10 seconds, stabilize for 5 seconds, and test for 10 seconds to see the pressure fluctuations.If the curve is like an electrocardiogram, the stabilization time must be lengthened.Don't rush to complain that the instrument is "picky". Try it a few times and you will find that it is actually very obedient!

What should I do if there is a gas leak?Don't panic, there is a "first aid kit" here

When you discover that a product is leaking, is your first reaction to drop the tester?Don't worry, Hai Ruisi tells you that air leakage is not terrible, but the terrible thing is that you can't find the reason.One of the common problems is aging seals – just like the tape on your door will harden over time, the same goes for the product.For example, a customer tested the battery case and found that it kept leaking. Later, he found out that the sealing ring had been used for half a year and needed to be replaced.It is also possible that the work clamps are misaligned and are clamped crookedly, and the anger will naturally escape.This situation is like if you wear shoes without tying them, they will fall off after taking two steps. Strange shoes are useless, you have to blame your own craftsmanship.

Another "culprit of air leakage" is excessive test pressure.Some people think that the greater the pressure, the easier it is to detect problems. As a result, the product "exploded" directly.Although Tanshuo's equipment can handle high voltage, it is recommended to set a reasonable range according to the product manual.For example, when testing the waterproofness of a watch, the IPX7 standard is generally 10kPa. Don't increase it to 50kPa. That is not a test, it is "murder"!Also, check the pipe connections. Loose screws or dust on the interfaces may be the cause of air leakage.Don’t panic when you encounter problems, start with the simple ones, and you can handle 99% of the cases by yourself.Have you ever encountered any weird air leakage problems?Leave us a message and let us know!

Practical tips from Haireisi: Make testing smoother

After reading the principles and problems, are you eager to get started?Don’t worry, Hai Ruisi has put together some super practical suggestions for you, ensuring that your air tightness test will go smoothly and be as relaxing and comfortable as drinking milk tea!

1. The environment should be as stable as an old dog: Find a corner with stable temperature and humidity to place the instrument, and don’t let it fall in love with the air conditioner.For example, a factory placed a tester by the window, but when the wind blew, the data was completely messed up.
2. Adjust the parameters to "Private Customization": Don’t be lazy and use the default values. Adjust the time and pressure according to the product characteristics.If you test a small headset, 5 seconds may be enough; if you test a large water tank, 20 seconds may be enough to start stably.
3. Perform regular "physical checks" on the instrument: Sealing rings, pipes and other parts will become "tired" after being used for a long time. Check them every six months, which is more diligent than changing your toothbrush.
4. Recording is like writing a diary: Write down the parameters and results after each test, and it will be much easier to reproduce next time.It's like memorizing recipes when cooking, so you don't have to rely on feeling every time.
5. Don't rush to complain about air leakage.: Start with the little things, like clamps, seals, and pressure settings.Just like if you lose your keys, go through your pockets first, don't rush to open the door.
