automatic banding machine,
automatic grooving machine
Lateral load 4.6 - 5.6 KN blow - off testing machine for testing PTFE shock pistons
Purpose of this test:
to determine the friction for PTFE banded piston when adding different weights. The test is performed with a constant lateral force applied to the piston during the pressure build up over the piston. Automatically get the average friction after testing five cycles.
1. Put the testing tube into shock absorber oil to assure the oil in the ID of the tube.
2. Fix the piston into the piston rod
3. Put the piston rod and testing tube into the working cylinder
4. Turn on the power and adjust to automatic mode
5. Open the software, set the following parameters:
6. Click button of alternating motion to test the machine fixtures. To confirm friction level is right and oil distributes well in ID
7. Don’t add the weights to confirm the fixtures at the initial place and make zero for the data.
8. Click button of alternating motion, piston will be moving at the stroke of ± 30mm with 5 cycles.
9. Add the weights of 7.5Kg, 15Kg, 22.5Kg, 45Kg, do the same testing as step above, record the data and curves.
10. Stop the testing, take down the weights and turn off the power.
1.Can check the PTFE banding result
3.Machine design according to big shock absorber factory in the world
4.Can test friction and blow-off testing in the same testing machine
5.Can get the curves after testing
All PTFE banding piston with different size rang from 20mm to 45mm
