Office chair pull back testing machine

Office chair pull back testing machine WSD-8603

one. Test scope:

This machine according to BIFMA5.1EN1335-3 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 rotary 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 size of the test force 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:

1. Load load: 0-- 300Lb adjustable

2. Force loading accuracy: dynamic 5% static 1%

3. Stroke: 0~500mm adjustable

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

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

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

7. Test times: 0-9,999,999 times can be set arbitrarily

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

9. Display mode: full color LCD touch screen

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