Four-station pull back testing machine

Four-station office chair pull-back testing machine WD-8603A

one. Test scope:

This machine according to BIFMA5.1EN1335-3 QB/T2280 and other standards to test the back of the office chair after a certain amount of force and a certain number of tension, check the chair back and the chassis of the chair fatigue resistance and damage to the components.

two. Applicable standard: BIFMA 5.1:2002 EN1335-3:2000 QB/T2280-2007

Three. Main composition

1. The test force size is measured and controlled directly by the force sensor, and the accuracy meets the standard requirements.

2. Equipped with solenoid valve, pressure regulating oil and water filtration dual, position sensor, force sensor self-dynamic test component loading force value

3. The number of tests can be set, and the number of tests can be directly displayed in real time

4. Equipped with sensors to detect specimen damage, automatically stop the test and retain the test results

Four. Technical parameters:

2. Load load: 0-- 300Lb adjustable

3. Force sensor type: Spoke type (high accuracy, good stability, good strength)

4. Force loading accuracy: dynamic 5%

Static 1%

5. Stroke: 0~500mm adjustable

6. Loading Angle: 90° with the back of the chair (there is an adjusting mechanism to adjust the Angle)

7. Test speed: 10~30 times/min can be set arbitrarily

8. Test times: 0-9,999,999 times can be set arbitrarily 9. Control mode: PLC control + force value sensor to form closed loop force control

10. Display mode: full color LCD touch screen

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

12. Cylinder and servo valve: AirTAC

13. Gas pressure: 6 KG/CM2

14. Back loading module: in line with standard requirements and eccentric loading

15. Configuration seat load: 102kg 4 sets

16. Seat load set safety measures to prevent personal injury accidents caused by self-fall during the test.

17. Other appliances: Omron and Taiwan Shilin
