This time, a coffee machine manufacturer sought a leak testing solution from Hirays Technology. The customer needed to conduct a leak test on the steam pipe.The customer hopes that Hirays Technology can customize the best leakage testing solution based on the characteristics of the steam pipe of the coffee machine, and produce the corresponding steam pipe leakage tester for production testing.The following content is a sharing of this solution.

1. The importance of coffee machine steam pipe sealing

Fetching coffee and making coffee milk foam need to be completed through the steam pipe of the coffee machine. However, the steam pipe is in a high-temperature and high-pressure working environment in the coffee machine. It is required to have a certain degree of sealing to maintain the normal working pressure of the coffee machine and prevent steam and boiling water from leaking during use to ensure user safety.

2. Key points of coffee machine steam pipe leakage test

After an in-depth understanding of the steam pipe of this customer's coffee machine, we found that pressure should be taken into consideration when testing the coffee machine for leaks.Secondly, due to steam pipe modeling issues, we need to use molds for auxiliary testing.

3. Brief description of leak test solution

This time, Hiraysi Technology used direct testing. It first customized a specific mold for the steam pipe to fix the product to be tested. One end was sealed and the other end was left as an inflation port.Then the tooling connected to the air source will inject a certain volume of gas into the steam pipe, and then cut off the compressed air supply to the component (the valve is closed), and let it stand still for a period of time to stabilize the pressure. The working pressure of the steam pipe must be taken into consideration. After the established measurement time, the pressure change is measured, and the leakage is used to determine the tightness.The tester can support leakage testing, obstruction testing, positive pressure testing, negative pressure testing, etc. It has a wide testing range and users can choose according to their own testing needs.

6. Introduction to the basic functions of steam pipe leakage tester

1. Using a large-size touch screen as the human-machine interface, you can easily monitor the test results and set various parameters during the waterproof test process.

2. It has an alarm function for qualified and unqualified products, which can eliminate the possibility of manual misjudgment and misdetection.

3. With 4-channel switch input and 8-channel relay output, it can be controlled by external sensors and switch buttons, and can control external relays, solenoid valves and other actuators, conveniently realizing full automation of testing.

4. The tester has 200 user subroutines. By setting the subroutine parameters on the touch screen, the user can connect different subroutines in series to form a test process. Through the I/O interface of the leakage meter, the leakage meter can accept control signals from external sensors and control external actuators (relays, solenoid valves, etc.).Thereby automating the testing process.

5. It has a test data recording function, and the test data can be downloaded to a USB flash drive and displayed on the computer.

6. It has barcode scanning function, which can track and record defective products and repair status; host computer function, etc.
