On an industrial production line, time is money.airtightness leak detector(also known asAir tightness testing equipment,Sealing Tester)Although accurate and reliable, it can be a bottleneck to productivity if the test cycle is too long. So how long do the various stages of the testing process actually take? And how can we improve efficiency while maintaining quality?
I. The five stages of detection: their respective time codes
Air tightness testing is like a carefully choreographed dance, where each movement has its own purpose and required timing. But unlike a fixed dance, these times are flexible and adjustable as the 'stage' (the product) and the 'music' (the test requirements) change.
front exhaust--Stage preparation phase, which usually takes a few seconds. Like clearing the stage before a show.This step expels air from the product under test, creating a clean environment for subsequent testing.. For products that need to be tested under vacuum conditions, this phase may take longer.
Inflation time--The moment the lights come on for a few seconds to a few tens of seconds.The larger the volume, the more time it naturally takes to fill the required gas, just like filling a large pool of water!. High-pressure testing is like trying to fill a pool to a higher level, again requiring a longer inflation time.
equalization time-- A moment when the actor is in position, typically a few seconds to a dozen seconds. During this seemingly static phase, subtle adjustments are actually being made within the system, theAllow the pressure of the product under test and the reference chamber to reach a perfect equilibrium, ready for accurate measurementsThe
detection time-- the centerpiece of the show, ranging in length from a few seconds to tens of seconds. This is the soul of the entire process, and the system is at this point fully focused on monitoring pressure changes and capturing tiny leak signals. In theory.The longer the detection time, the smaller the leak that can be found, but also the less efficient it isThe
Pressure relief time--Curtain call session, which takes a few seconds. It's like resuming the stage after a show thatThis step releases the test pressure and prepares for the next round of testing. Relieving pressure after a high-pressure test is like deflating a large balloon, and naturally takes more time.
II. The Wise Way to Improve Efficiency
Optimizing the time parameters of an airtightness test is like an experienced director who knows how to make the whole show tighter and more efficient without sacrificing the quality of the performance.

Exhaust: only necessary preparations
First, ask yourself: is this step really necessary? If the test doesn't require a pre-established vacuum, consider just skipping it.
If it does need to be vented, find thatJust enough time to get the job done.. Just like boiling water, you don't need to wait for the water to boil for a long time before you can make tea, the water is just boiling.
Inflatable: fast and steady balance
Choosing the right gas source and line is like choosing a faucet with a high water flow rate that fills the sink quickly.
precise control of the inflation process.When the target pressure is reached, extend the inflation time appropriately(e.g., 1x longer, inflate from 5 to 10 seconds)(math.) genusto avoid under-inflation due to peak compressed air fallback. This is just like when inflating a tire, if you don't extend the inflation time, you may under-inflate the tire due to momentary fluctuations in air pressure.
Balance: finding the shortest path to stability
The key to balancing time is toFinding the shortest wait time that ensures accurate measurements without wasting excessive time. This delicate balance can be found by looking at the trend of the pressure curve.
Controlling the temperature of the test environment, like keeping the room at a constant temperature, allows the product to reach a steady state faster and reduces waiting time.
Testing: Accuracy is king
Detection time optimization is a combination of science and art. It depends on yourHow strict are the quality standardsand the ability toHow much risk to acceptThe
Start with a more conservative detection time, gradually reduce it, and closely monitor the false positive rate. This incremental approach helps you find the optimal balance of efficiency and accuracy.
Using a high-precision sensor is like using a high-powered microscope, revealing more details in a shorter period of time, thus shortening the required observation time.
Pressure relief: safe and quick release
optionPressure relief valves for high flow rates, like opening a larger spout, allows the pool to empty faster.
For high voltage testing, consider usingGraded Pressure Reliefway, descending step by step like a staircase.Protecting products and equipment while saving time overallThe
III. Global optimization: the power of systems thinking
In addition to optimizing each stage individually, we can also improve efficiency from a holistic perspective:
Streamline fixtures
Designing fixtures that are smaller in size reduces the amount of space that needs to be filled and emptied, just like using a smaller pool that naturally fills and empties faster.
Upgrade equipment
Choose better performanceairtightness leak detectorFor example, the Jingcheng EngineeringJC-C10005 Differential Pressure Instrument, just like with a more advanced camera that captures a clearer image in less time.

intelligent software
Using inspection software with self-optimizing features, the system learns and adapts to the characteristics of your product, automatically adjusting to the best parameters.

multichannel parallelism
If the conditions allow, you can choose the Jingcheng Engineering TechnologyMulti-channel airtightness testing equipmentThe test is performed on multiple products at the same time, like a multi-threaded process, dramatically improving overall efficiency.

IV. Final word of advice: quality is always the bottom line
In the quest for efficiency, we must keep in mind:The fundamental purpose of hermetic testing is to ensure product quality. Excessive shortening of testing time may lead to misjudgments or omissions, ultimately damaging product reputation and user trust.
By mastering the art of balancing time adjustments, your airtightness inspection journey will be much smoother and more efficient. After all, a good start is half the battle, and adequate balancing is a good start to accurate testing.
