Air tightness tester/sealing tester

The airtightness testing equipment combines airtightness testing with automated testing, and can use the airtightness testing instrument developed by our company according to customer requirements. The testing platform adopts PLC main control and touch screen Chinese display operation; Using the principle of steam to quickly clamp the product, wear-resistant silicone is used as the sealing element, and a high-precision pressure transmitter is notified to detect the upper and lower limits of the pressure generated inside the product during the constant pressure process to determine the sealing performance of the product. Fixtures are universal fixtures that can achieve a maximum of 90% or more for diversified products based on customer provided product designs. The testing process is distributed, OK automatically enters the next step of detection, NG corresponds to the indicator light on, and the sound and light alarm; The accessories used in the testing equipment are imported and well-known domestic brands, ensuring stable and reliable operation.

The airtightness detector is a universal gas detection instrument, which is suitable for leak detection, sealing detection, and waterproof detection. The airtightness tester, in conjunction with the testing fixture, applies compressed gas at the corresponding standard pressure to the inner or outer wall of the tested product, and then cuts off the inflation circuit. If the tested product leaks, the instrument will accurately monitor subtle pressure changes. The instrument processor will then make accurate judgments by analyzing and comparing the set parameter standards, and output OK/NG through sound and light alarms. The test results will be stored in Excel format on the instrument computer and can be exported to a USB interface to a USB flash drive.

The airtightness tester adopts the direct pressure principle and uses compressed air (or negative pressure) as the medium to test products. It is a non-destructive testing instrument. Sealing the workpiece with an external fixture forms an independent sealed cavity for the tested workpiece. Fill the tested workpiece with compressed air (or negative pressure). By its high precision and comprehensive functions, it can detect pressure changes inside the workpiece to determine whether the workpiece is qualified.

1. Connect the instrument/fixture to the power and air source, connect the instrument testing port to the fixture mold port, and connect the fixture control signal line to the instrument external control interface.

2. Log in through the human-machine exchange interface, retrieve the test parameter group, debug the test pressure, and enter the testing interface to use it normally.
