In modern industrial production, airtightness testing plays a crucial role. Whether it is to ensure the performance, safety or service life of the product, airtightness testing is an indispensable link.
For example, in the automotive industry, good airtightness can ensure the normal operation of automotive parts and avoid problems such as fuel leakage and water ingress; in the field of medical devices, airtightness is directly related to the accuracy of the equipment and the safety of the patients; in consumer electronics, such as cell phones and watches, the requirements for airtightness, such as waterproofing and dustproofing, are also increasing.
I. The nature of airtightness testing
Airtightness, i.e., the ability of an object to prevent the penetration and leakage of gases and liquids. Imagine the consequences of a leaky tire, a seeping hose, or water in diving equipment.The mission of the airtightness tester is to accurately determine whether the sealing and waterproofing of a product is up to standard before it leaves the factory.
In this article, we will introduce two mainstream testing technology in-depth analysis, differential pressure quantitative and differential pressure airtightness tester.
1. Differential pressure quantitative airtightness tester
Working Principle
Differential Pressure Quantitative Tester designed for fully enclosed products.It is like doing a "Precision Airtightness Physical Examination" on a product. It ensures that the sealing of the product meets extremely high standards through a standardized testing process.
The testing process includes:
- Inflation phase: Pressure set according to preset criteria
- Equilibrium phase: waiting for pressure to stabilize
- Detection phase: precise measurement of pressure changes
Diving equipment battery compartment differential pressure quantitative air tightness tester
As an example, the test parameters for the battery compartment of a diving equipment are as follows (adjustment is supported):
- Inflation time: 40 seconds
- Equilibration time 1:40 seconds
- Equilibration time 2: 30 seconds
- Test time: 20 seconds
- Leakage range: ±3000 Pa
- Test pressure: 1000 kPa
Applicable Scenarios
Particularly suitable for fully enclosed, high-precision sealing requirements, such as:
- diving equipment
- Precision Medical Devices
- High-end electronic equipment
- Aerospace key components
2. Differential pressure airtightness tester
Working Principle
Differential pressure direct pressure (i.e. differential pressure) airtightness testers are more suitable for open or semi-open products.With the help of highly sensitive differential pressure sensors inside the instrument, it monitors the pressure difference between the tested part and the standard part in real time during the pressure holding process, and immediately determines that there is a leakage problem in the product once the pressure difference is out of the normal range.
Key Features:
- Very high accuracy: up to 0.1 Pa
- High sensitivity and fast response
- Suitable for a wide range of product types
- Multiple products can be tested at the same time
Hardware casting differential pressure airtightness tester, three products at a time, precision resolution 0.001ml/min
Applicable Scenarios
More suitable for open or semi-open products such as:
- Auto Parts
- Hardware Die Casting
- Pipe Connectors
- Industrial valves
Second, the core difference between the two detectors
target of detection
The Differential Pressure Quantitative Airtightness Tester mainly focuses on the airtightness testing of fully enclosed products, which are like a separate sealed world and need to be verified by precise quantitative pressure testing.
Differential pressure direct pressure airtightness tester is better at dealing with open or semi-open products, and its structural features make direct monitoring of pressure changes an effective way to determine leakage.
Detection Principle
- Differential pressure direct pressure type: Comparative differential pressure change monitoring
- Differential pressure quantitative type: Standardized quantitative pressure test
Third, the combination of MES systems and the Internet of Things
In addition.Jingcheng Industrial Science and Technology these two differential pressure airtightness tester support MES system, you can remote monitoring and viewing, to achieve intelligent production and operation management.
The combination of MES system and Industrial Internet of Things (IOT) will realize the comprehensive monitoring and management of the production process. By connecting the airtightness instrument to the Internet of Things and uploading real-time inspection data to the MES system, the enterprise can realize real-time monitoring, data analysis and quality traceability of the airtightness of the products on the production line, and improve the level of intelligence in production management.
IV. Development of customized solutions
