Plastic product air impermeability test system

Abstract

The invention discloses a plastic product air impermeability test system. The system comprises an air compressor and an air impermeability test device, wherein the air compressor is used for providingan air source; an electromagnetic switch valve is arranged on the air compressor; the air impermeability test device comprises a control unit, a sensing unit and a feedback control unit; the sensingunit comprises a differential pressure sensor and an absolute pressure sensor, which are arranged at the front end of the air impermeability test device; the differential pressure sensor and the absolute pressure sensor are respectively connected with the control unit; the differential pressure sensor is used for acquiring differential pressure between a standard component and a test piece; the absolute pressure sensor is used for acquiring absolute pressure of the test piece; the feedback control unit comprises a temperature detection unit; and the temperature detection unit is connected withthe control unit and is used for compensating test parameters. The system provided by the invention is high in test precision, simple to operate, good in stability and high in detection efficiency, and is capable of ensuring the production quality of plastic products.

Description

technical field [0001] The invention relates to the technical field of plastic product testing, in particular to a plastic product air tightness testing system. Background technique [0002] At present, people's requirements for product quality are constantly improving, and plastic products have become important product raw materials due to their excellent molding performance and low cost. Some plastic products, such as medical and chemical industries, have high requirements on the airtightness of plastic products; the traditional method of bubbling in water and smearing soapy water requires manual observation and judgment, and cannot be automatically detected, which is not only inefficient, but also has individual errors caused by differences. Contents of the invention [0003] The object of the present invention is to provide a plastic product airtightness test system to solve the above-mentioned technical problems existing in the prior art. [0004] In order to solve ...
