1. Why is Leak Testing Necessary for the Steamer Inner Pot?

As a core component of household steamers, the inner pot is constantly in contact with water and high-temperature steam. If the sealing performance is insufficient, problems such as water leakage, steam escaping, reduced heating efficiency, and even moisture damage to electrical components can easily occur. This not only affects the service life of the product but may also pose safety risks. Therefore, strict leak testing of the steamer inner pot is an essential step to ensure product quality and user safety.

2. Main Testing Locations of the Steamer Inner Pot

We need to focus on testing the following key areas:

• The joint between the bottom of the inner pot and the heating plate, where welding gaps are most likely to occur;
• The connection between the inner pot and the outer shell, ensuring that the sealing ring is properly fitted;
• Interfaces such as the exhaust port and overflow outlet, as these detailed positions often have tiny leaks.

3. Operating Steps of Huafu Brothers Sealing Tester

In this test, we used the Huafu Brothers Leak Tester to perform precise testing on the steamer inner pot. The specific steps are as follows:

• Product Placement: Place the steamer inner pot into the customized fixture and secure it properly;
• External Control: Connect the tester’s air circuit interface to the sealing port of the pot fixture;
• Parameter Adjustment: Set the test parameters: pressure 20 kPa, holding time 10 seconds;
• Start Testing: After pressing the start button, the tester will automatically inflate and monitor the pressure curve in real time;
• Result Output: Judge based on the results: if the pressure remains stable, the sealing is qualified; if the pressure drops, it indicates a leak.

Throughout the testing process, the Huafu Brothers tester demonstrated excellent stability and high sensor sensitivity, capable of quickly identifying even tiny leaks. To help customers better understand the operation, Huafu Brothers also provides an instructional video, clearly showing the entire process from fixture installation to result determination.
