Air tightness tester: How does this type of testing equipment actually operate? PLUS Automation

Air tightness leak detectorIt is a professional testing device widely used in industries such as industrial manufacturing, automotive, and aerospace. We will provide a comprehensive introduction to the air tightness leak detector from the perspectives of principle and application.

An air tightness leak detector is an instrument used to test the sealing performance and leakage problems of objects. It applies a certain air pressure or vacuum to enclose the object under test, and then evaluates the air tightness performance of the object by detecting gas flow or pressure changes.

The working principles of air leak detectors can be divided into two types: the flow method and the pressure method.

1. Flow method: The flow method evaluates the air tightness performance of an object by measuring the gas flow rate. During the test, the air tightness tester encloses the object under test in a sealed chamber and applies a certain air pressure or vacuum. Then, the air tightness performance of the object is evaluated by measuring the gas flow rate into or out of the sealed chamber. If the gas flow rate exceeds the set threshold, it can be determined that the object has a leak problem.

2. Pressure method: The pressure method evaluates the air tightness of an object by measuring the pressure changes inside it. During the test, the air tightness tester encloses the object under test in a sealed chamber and applies a certain air pressure or vacuum. It then monitors the pressure changes inside the object. If the pressure change exceeds the set threshold, the object can be judged to have a leak.
