Application Fields of BOLYFA Watch Airtightness Testing Fixture
Quality Inspection in Watch Manufacturing Factories
During the watch production process, the airtightness of each watch is tested to ensure that the product meets the waterproof standards and guarantees product quality.
Verification of Waterproof Performance after Repair
After a watch has been repaired, it is tested with the airtightness testing fixture to verify whether its waterproof performance has returned to the original level.
Verification of Waterproof Design in the R & D Stage
In the watch R & D stage, this fixture is used to test and verify different waterproof design schemes, providing a basis for optimizing the waterproof design.
The watch airtightness testing fixture, as a professional device, plays a crucial role in testing the waterproof performance of watches during the watch manufacturing and quality control processes.
Working Principles
Air Pressure Testing Method
By filling compressed air into the sealed cavity and monitoring the pressure changes in real - time, the sealing performance of the watch can be judged. If there is a sealing problem with the watch, the pressure in the cavity will change abnormally.
Vacuum Testing Method
First, evacuate the sealed cavity to a vacuum state, and then closely observe the pressure recovery. If the watch has a leak, the vacuum environment will be disrupted and the pressure will gradually rise.
Water Pressure Testing Method
Completely immerse the watch in water and apply a certain pressure. By carefully observing whether there are any bubbles generated, the waterproof performance of the watch can be judged. If bubbles emerge, it indicates that there is a sealing defect in the watch.
Main Components
Sealed Cavity:This is a sealed test chamber that highly matches the shape of the watch. It can create a closed environment for the watch airtightness test to ensure the accuracy of the test results.
Pressure Control System:It has the function of precisely controlling the test pressure and can be accurately adjusted to the appropriate pressure value according to different test requirements.
Sensor:It can sensitively detect minute pressure changes and provide key data support for judging the airtightness of the watch.
Display/Recording Device:It can not only visually display the test results but also record the relevant data for easy subsequent reference and analysis.
Fixture System:It is used to firmly fix the watch and ensure a good seal between the watch and the sealed cavity, preventing leakage during the test from interfering with the test results.
Technical Parameters
Test Pressure Range:Generally, it is in the range of 0.1 - 10 bar. The specific value will be adjusted according to the different waterproof grade requirements of the watch.
Accuracy:It can reach ±0.1%FS, ensuring the high accuracy of the test data.
Test Time:The duration ranges from a few seconds to a few minutes, depending on the test method and the complexity of the watch.
Leakage Rate Detection Sensitivity:It can reach 0.01 mbar/s, which can effectively detect extremely subtle leakage situations.
