Air pressure burst strength testing instrument

Abstract

The invention provides an air pressure burst strength testing instrument. The air pressure burst strength testing instrument comprises a mechanical part and an electrical part, wherein the mechanical part comprises a box body, a working platform, a membrane assembly, a test sample holding cylinder and a protection cover, and the working platform, the membrane assembly, the test sample holding cylinder and the protection cover are arranged in the box body; and the electrical part comprises a CPU (Central Processing Unit), an air pressure sensor, a displacement sensor, a control screen, a booster pump and a plurality of solenoid valves, the air pressure sensor, the displacement sensor, the control screen, the booster pump and the solenoid valves are connected with the CPU, and the CPU is used for controlling the booster pump and the solenoid valves and adjusting a pressure boost speed rate and a pressure boost range of an air inlet as well as a pressure and a displacement output by the test sample holding cylinder in real time according to data detected by the air pressure sensor and the displacement sensor as well as a control command input by the control screen. According to the air pressure burst strength testing instrument, environmental pollution caused by the use of oils in a hydraulic bursting process and the troubles of oil adding and oil linkage in an experiment process can be avoided, and the air pressure burst strength testing instrument has the characteristics of safety, reliability, environmental friendliness, convenience and the like.

Description

technical field [0001] The invention belongs to the field of textile equipment, in particular to an air pressure burst strength tester. Background technique [0002] With the rapid development of the market economy, the volume of import and export trade in the textile industry has increased significantly, and the work of fabric burst strength testing involved in production, new product development, and trade has also increased significantly. Because textile materials, especially woven fabrics, knitted fabrics, and non-woven fabrics, have poor quality uniformity and large discrete changes in performance, it is required to test each quality index with a relatively large sample size to obtain a test that represents the overall performance. result. The test method stipulates that the tensile strength is not suitable for some fabrics (such as knitted fabrics and lace), but the bursting strength test can be used instead. When the fabric is damaged, it is often subjected to forc...
