Air tightness test device is an instrument that uses gas pressure to carry out non-destructive waterproof testing of products. It is mainly used for medical devices, auto parts, electronic appliances, valves and pipelines, security lighting, digital communications and other products. Let's talk about the debugging of the tooling and fixture of the air tightness test device.
Generally, air tightness test devices can be divided into two categories: products with test pores and products without test pores. For products that test pores, just connect the test gas pipe to the test pores, and then test them through the program set by the air tightness test device.
For products without test pores, due to different shapes, it is necessary to customize tooling and fixtures for the products, place the products in the mold, inflate the mold through the air tightness test device, and sense the change of mold pressure value, so as to judge whether the products leak.
Do you know how to debug the air tightness test device after docking? The manufacturer of gas booster pump will tell you some points:
1. Multi channel selection: the air tightness test device supports the simultaneous testing of four channels. When selecting the multi-channel test instrument, you can choose to open and close the test channel.
2. Internal signal control of air tightness test device: signal control points of each valve inside the instrument, manual operation or inspection of whether each valve inside works normally;
3. External signal control of air tightness test device; Connect the signal control points of the external tooling, manually operate or verify whether the external signal points work normally;
4. There is a set of profiling die on the fixture of the air tightness test device. Whether this profiling die can be replaced or replaced is because the die has been used for too long, and the internal cavity will leak due to wear or damage. At the same time, due to the different shapes of users' products, if the shapes of products are different, it can be replaced with other profiling dies.
This is the case for the commissioning of the tooling and fixtures of the air tightness test device. If you want to operate, you should make preventive preparations in advance to prevent unexpected conditions. For more information, please visit the website http://www.sdjingtuo.com Take a look.
