Mattress fatigue durability testing machine

Mattress fatigue and durability testing machine WSD-8621

one. Test scope:

This test is mainly used to evaluate the mattress after a certain weight of the loading module, a certain height, a certain frequency alternating free fall, a certain number of times after loading, the mattress parts have no damage and the overall function has no loss.

two. Applicable standard: QB1952.2-2004 QB/T2600-2003

Three. The main components:

1. The type of test can be completed: fatigue endurance test and compression measurement of mattress.

2. Control mode: PLC+ load element force closed-loop control.

3. Test process single-key automatic operation: the specimen is placed, as long as a key is pressed, the following test process is completed:

1) The first step is to measure the compression of the mattress

2) The second step is to carry out the fatigue endurance test of the mattress

3) After the machine reaches the set number of tests, it will automatically stop and return to the original position.

4) When the specimen is damaged, the pressure is automatically relieved, the cylinder returns to the original position, and the current test value is displayed

3. Safety device:

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

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

3) Circuit switch automatic detection, leakage automatic stop

4) The up and down lifting has the upper limit and the lower limit micro 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.

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

5 Can basically realize the unattended test, the test will be automatically stopped after the test is completed or the specimen is damaged, and there is an audible and visual alarm, and the test result will be automatically retained.

Four. Technical parameters:

1. Load unit capacity: 50kg 1

2. System force accuracy: ±1% (static) 0-5% (dynamic)

3. Test frequency error: ±1 time

4. Surface loading module loading mass weight: 50±5Kg

5. Number of loading modules on the seat surface: 2

6. Test speed: 19-21 times /min

7. Maximum width of test mattress: 2500mm

8. Maximum length of test mattress: 2500mm

9. Displacement meter range: 500MM

10. Displacement accuracy: ± 0.5MM

11. Control mode: PLC control + force sensor to form force closed-loop control

12. Display mode: full color LCD touch screen

13. Data storage method Computer memory and U disk

14. Report generation method: The data can be automatically printed on the ordinary computer through the U disk and the test report

15. Brand of cylinder and other pneumatic components: festo

16. Stop mode: Automatically stop when the set number of tests is reached, the specimen is damaged or the deformation is too large

17. Other electrical appliances: Omron and Taiwan Shilin

18. The main body of the machine is steel component, high strength, not easy to deformation.

19. The base of the machine is solid steel with good stability, equipped with reinforcing bars and flat feet for water transfer.

20. Electrostatic spraying of machine appearance, electroplating of other parts, high rust prevention ability, beautiful appearance.

22. Air source: 0.6MPA
