In order to improve detection accuracy and efficiency, realize detection automationAir tightness leak detection equipment, the currently popular air tightness testThe measurement method is the differential pressure method. If the container being measured leaks, it will inevitably cause the loss of gas mass in the container, causing the original content of the container to leak.Some air pressures decrease. By measuring the gas pressure drop in the container, the actual amount of gas leaking from the container can be deduced to achieveAir tightness leak detection equipmentpurpose.

Based on differential pressure measurementAir tightness testing equipmentAlthough compared with traditional detection methods, this technology has improved detection efficiency andThe degree of automation, but in some cases still cannot meet the requirements of production efficiency, especially when the internal volume of the workpiece being tested isWhen it is larger, in order to ensure a certain detection accuracy, sufficient inflation time and balancing time must be ensured.Because, chargingDuring the gas filling process, the temperature of the gas will change. If the filling time and equilibrium time are not long enough, the temperature change cannotWhen it stabilizes and enters the detection process, temperature changes will cause changes in differential pressure, which will reduce the detection accuracy.At this time, checkMeasurement accuracy and detection efficiency have become a contradictory relationship.In order to improve the efficiency of leak detection, some domestic and foreign research institutionsSome theories and methods were proposed, such as rapid inflation method, temperature compensation method, and adding fillers to reduce the number of measured workpieces.Content volume and other methods.These detection efficiency improvement measures have been verified and developed in practical applications.Ruhiruisi AutomationTechnology Co., Ltd. provided by a gearbox manufacturerAir tightness testing equipment, by adopting the above efficiency improvement measuresAfter that, the working rhythm is changed from the original every 2 minutes1items increased to1minute1parts, the detection efficiency is improved50%.In addition, forTo meet the needs of automated production, the company has developed various integrated feeding and sealing equipment based on air tightness testing equipment.It is an automated air tightness leak detection equipment that integrates functions such as detection, display, alarm, and discharge.

aboveAir tightness testing equipmentofAlthough technology can detect whether the workpiece is leaking, it cannot determine the specific location of the leak.Set.In some cases, when the workpiece fails to pass the inspection, it is necessary to put the workpiece into the water tank and determine it through water inspection.Leak location.In order to improve detection efficiency, new leak detectors often combine air tightness detection (dry leak detection) and water detection functions.combined in one device.After the workpiece to be tested enters the leak detector, dry leak detection is first performed. If the workpiece is qualified, the workpiece will beSend items out.If the workpiece is unqualified, the workpiece will be automatically sunk into the water tank under the air-tight leak detector, and a water test will be performed to ensure that the workpiece is unqualified.The location of the leak point is determined, which further improves the automation and detection efficiency of air tightness detection.In addition, as computers,With the rapid development of electronic sensing technology, the development of leak detection technology will usher in new development opportunities.Air tightness testing of the futureMeasuring technology will further develop in the direction of high precision, high efficiency, and intelligence.Wide application of modern air tightness testing equipmentIt will also play an increasingly important role in ensuring product quality, ensuring production safety, and improving corporate economic benefits.

In order to improve the efficiency of air-tight leak detection equipment, Hirays Technology has proposed some theories and methods, such as rapid inflationmethods, temperature compensation methods, adding fillers to reduce the internal volume of the workpiece being measured, etc.These detection efficiency improvement measures are inIt has been verified and developed in practical applications.
