HJYW-600B computer&servo control constant stress manhole cover tester

Specifications

 Brief Introduction:

This machine is designed and manufactured according to CJ/T3012-1993<<CAST IRON MANHOLE COVER>>, CJ/T121-2000<<REGENERATIVE RESIN COMPOSITE MATERIAL MANHOLE COVER>>, It is mainly used for testing the loads capacity of manhole cover. Good structure. Pls kindly note: for HT(gray cast iron materials) materials, the machine is just for doing the destructive testing, for QT materials(ductile cast iron materials) and other composite materials, the machine can do the 

Main technique parameter

1. maximum testing force:600KN

2. effective testing space:1200mm X 1200mm

3. working station height: 500mm

4. force value precission: ≤ 1%(prior to I class)

5. adding loads speed range: 0.1~25KN/s

6. deformation testing range:0~20mm 

7. deformation testing precission: computer sampling 0.01mm

8. piston stroke: 350mm

9. overload protection point: automticaly unloading while exceeding 3% of full range

10. loading value displaying precession: 0.1KN

11. adding loads method: hydraulic

12. controlling loads method: computer control and manual stepless speed regulation, online programming available.

13. adding loads medium: 46# wear-resistant hydraulic oil.

14. the system is equiped with Lenovo computer, LCD display, HP printer.

15. motor power: 0.75Kw

16. working voltage: 380/220v

17. overall dimensions of host machine: 1600mm*1200nn*1300mm(LxWxH)

18. overall weight of host machine:2500KG

MAIN FEATURE:

1. host machine frame is rigid structure, so it can ensure the safety during testing progress.

2. adding loads cylinder is located in the upper position, working platform is 500mm height, so it is very easily to move the test piece in or out.

3. ball hinged type connection between rigid heel block and the out end of piston ensure the entire touch between manhole cover and conter-force board, and so that the tested loads is true.

4. a specail sealing materials was used between the cylinder and piston so that the high sealing, low friction,long life is available.

5. professional hydraulic station speccial for testing machine, low noise and long life

6. hyperfine oil filter ensure the clean inside oil pipe system so that the execute component works well efficiently.

7. computer controll, current force value, peak value, testing process can be  displayed in time.

8. high speed sampleing is availble, testing curve can be recorded in time during testing process.

9. the fuction of data and report form handling provide a exclusive report form editing tools of graphical interface with the feature of easy operation, easy to learn, as well as very convenience to print testing curve and value.

10. control mode: constant speed stress, constant speed testing force, testing froce holding, and testing force&testing curve to be displayed on screen. force-time curve is available, control mode can swift smoothly.

11. automatic zero clearing system built inside software eliminate the personality error such as reading error.

12. overloads function can stop the machine automatically when testing force or displacement goes beyond the rated value of the tester.

13. cippling loads and deformation value is automatically sampled and printed into report form.

14. deformation is measured at the bottom of test piece so that the data is accuracy and stable.

15. customer can program by themselves according actual demands, auto close-loop control, cyclic adding loads, loading speed, loading wave can be programmable. The whole procedure is full automation without any manual intervention.
