Leak Detection Chamber for Helium Leak Detector

Introduction of Leak Detection Chamber:

A leak detection chamber, professionally referred to as a accumulation leak detection chamber, is a sealed chamber used for accumulation leak testing of small workpieces. It is typically constructed from austenitic stainless steel or high-strength aluminum alloy, with dimensions standardized or customized based on the size of the workpiece under test. Its core function is the high-sensitivity detection of minute leaks.

Function of Leak Detection Chamber:

The core function of the leak detection tank is to provide a sealed "sniffing space" that amplifies leakage signals through helium accumulation, enabling highly sensitive detection of minute leaks.
Implementation of "Accumulation Method" Leak Detection:
This method accumulates and amplifies a tiny, instantaneous leakage signal into a strong, stable signal, thereby detecting extremely small leak rates that are difficult to identify with conventional sniffing probes.
Testing Workpieces That Cannot Be Directly Connected:
For sealed devices without pre-installed vacuum interfaces (such as chip packaging or sealed medical devices), the accumulation method is the only effective way to verify their overall sealing integrity.
Providing Quantitative Test Results:
By measuring the rate of helium signal increase and combining it with the known volume of the detection tank, the total leak rate of the workpiece can be accurately calculated, providing precise quantitative data for product quality assessment.
Improving Test Stability and Repeatability:
As the workpiece is fixed in a sealed environment, interference from factors such as ambient airflow and operational techniques is eliminated, ensuring highly stable and repeatable test results.
