Gas spring comprehensive strength performance tester

1、 Purpose:

This tester is suitable for testing the performance of gas springs (office chair gas springs) when used at room temperature and pressureintensityPerformance.

IItechnologyPrinciple:

This tester tests the strength and durability of gas springs through various technical principles, including:

1. The compressive strength testing area uses an electromagnet to adsorb the impact part, and the impact part is lifted by a servo motor, screw, and guide rod. When it is lifted to the desired height, the electromagnet is powered off, and the impact part falls freely, completing one impact on the sample.

2. The rotating test area simulates the durability of the rotating device during product use by placing a certain load on the seat surface of the office chair to rotate the chair surface relative to the base,

3. The lateral tensile strength testing area conducts lateral tensile durability and strength testing on the specimen with the assistance of a guide wheel and guide rope through a force application device

4. In the tensile strength testing area, a horizontal force application device is used to load the specimen at a specified speed and maintain the force value for a specified time to check whether the specimen is damaged

5. The stretching speed test area is compressed by a compressed gas spring and released to allow the pattern to stretch freely. The stretching movement speed is recorded by a displacement sensor

threeAccording to the standards
