JS-500QB Paper tube pressure tester

Usage

500QB is paper tube pressure tester; It is main used for testing the compressive strength of industry paper core,chemical fibre paper core and other paper core.

feature
1,;adopted industry computer controller.

2 ,,,.

It is equped with Liquid-crystal display for easy operate.

3 ,.

Adopted high precision electronic holland presses the sensing system,have excess load protection function.

4 ,.

It will be show the current examination value and maintains a peak value at same time,also Newton unit value and kilogram unit value.

5.

You can use deformation test method and limit test method.

6. GB 4857.4-84

Adopted standard GB 4857.4-84.

main parameter

,10 20 30 40 50% .

Test method: deformation test method ,10 20 30 40 50% ,for testing each part of Compressive strength.

limit test method: to test the burst or compression value of core.

,.

Predetermined value test method: When the load achieves the predetermined value, the appearance of sample will be change.

1-1 help

1,0.3-0.6 Mpa,220V,

To conect the windpipe under 0.3-0.6 Mpa atmospheric pressure and 220v power supply,then turn on the switch.

2,,,0.3-0.6Mpa .

After then,the display will show machine model,and adjust the working atmospheric pressure 0.3-0.6 Mpa.

3,,20mm,↓,,2,9,,.

Put the core in the middle of lower board,then adjust handwheel to make upward board far from core about 20mm,press twice ↓ on dispaly untill be show working interface;holds down stop button with 2 seconds ,the data will be reposition, or holds down key 9,the data will be clear and finished the preparation work

4,,,,,,,,,.29.

Automatic test,after finished the preparation work,press auto test button,the cylinder will work for underdraught,the current strength value which be showing on display will be more and more as underarught strength inreasing;the cylinder will return when core has be lost the compressive strength,at that moment,the table will be lost pressure as so as current value return to zero,and reserve the hightest compressive strength value .at last,holds down the stop dutton 2 seconds or key 9 to clear the current value.
