New generation of blow - off testing machine for PTFE banded piston applied in shocks
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.
Test method:
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:
Speed: 1mm/s
Distance: 60mm
Cycle: 5
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.
Some pictures during testing process:
STEP 1: install the piston into the proper piston rod, pay attention that the upper OD should be at the bottom.
STEP 2: put the whole piston rod into the tube slowly
STEP 3: put the whole tube into the sealing housing at the bottom
STEP 4: install fixed housing and sealing cover
TESTING CONDITION:
| ITEM | SPEC |
| TEMPERATURE | 85±5℃ |
| LATERAL FORCE | 145±5kgf |
| PRESSURE | 30MPa |
| TIME | Keep 3 mimutes |
| RESULT | Banding materail will not fall off or move. |
Competitive advantage:
1.Can check the PTFE banding result
2.Easily operation
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
Application:
All PTFE banding piston with different size rang from 20mm to 45mm
