Sofa elasticity durability testing machine

Computer controlled sofa elastic durability testing machine WSD-8620A

one. Test scope:

This test is suitable for the mechanical property test of the sofa, mainly to test the durability of the seat, back and armrest of the sofa. During the test, the loading module with certain row shape and quality is repeatedly loaded on the surface of the seat, back and handrail respectively with the specified loading form and frequency. The ability of sofa to withstand long-term repetitive load under daily use conditions is simulated in order to improve product structure or packaging reference.

two. Applicable standard: QB/T 1952.1-2003 Appendix A

Three. Main composition

1. Control mode: computer control + load element to form closed loop force control.

2. Can set the test force, and can directly display the test force in real time, and automatically alarm various faults.

3. Number of tests: 0-- 999,999 can be set arbitrarily, and can directly display the number of tests in real time, automatic stop after reaching the set number, stoppage or power off will automatically retain the test results.

4. Seat compression performance test: equipped with high-precision displacement meter can complete the seat compression performance test.

5. Safety device:

1). Maximum capacity setting value: When the sense of force reaches this value, it will automatically stop.

2). Maximum displacement setting value: When the displacement reaches this setting value, it will automatically stop.

3). Automatic detection of circuit switch, automatic shutdown of leakage.

4). Failure stop: When the specimen is damaged, it will automatically stop.

5). The up and down lifting has the upper limit and the lower limit micro-motion protection device: when the upper limit or lower limit is reached, the micro-switch turns off the power and automatically stops to prevent improper operation from causing damage to the instrument.

6. Control mode: set load, frequency setting, time setting.

7. Equipped with solenoid valve, pressure regulation filter oil filter water double, equipped with buffer tank, constant air pressure.

8. It can basically realize unattended test, the test will be automatically stopped when the test is completed or the specimen is damaged, and there is an audible and visual alarm, and the test results will be automatically retained.
