BJJY-W600KN microcomputer controlled electro-hydraulic servo shaft cover pressure testing machine is designed and made by CJ / T3012-1993 "cast iron check shaft cover", CJ / T121-2000 "regenerative resin composite material inspection well cover" and JC889-2001 "steel fiber concrete check well cover", GB/T 23857-2009 "check well cover" and other industry or national standards. The structure and performance of the tests for carrying capacity and deformation conform to the requirements of the experimental specification.

Note: the specimen of HT material is only destructive test; QT material or other composite materials are tested for cyclic, deformation and failure.

1. The main engine adopts a high rigidity structure to ensure the safety during the test.

2, loading the oil cylinder on the table, the height of the table 500mm, easy to take the manhole cover test piece.

3, the ball block joint between the rigid pad and the piston pushing end ensures that the contact between the manhole cover and the reaction plate is complete, so as to ensure the authenticity of the bearing capacity.

4, oil cylinder and piston are sealed by special materials to achieve high sealing, low friction and long life.

5, the microcomputer controlled servo manhole cover pressure tester adopts professional test engine oil pump motor set, low noise and long life.

6. Choose super precision oil filter to ensure cleanliness in the oil circuit system so as to ensure the long term work of controlling the execution components.

7. Microcomputer controlled electro hydraulic servo manhole cover pressure test machine computer automatic control, real-time display current force value, peak value, test process information, etc.

8. The test process records the test curve in real time and sampling at high speed.

9. The processing function of data and report provides the user with a special report editing tool for graphic typesetting. It has the characteristics of flexible operation and easy to learn, and can easily print test curves and test values.

10. The control mode has the control function of isokinetic stress, isokinetic test force, test force retention and so on. The screen display function of the test curve, the strength of the test curve and the time curve of the test curve, and the smooth conversion of the control mode.

11, the software set up the automatic clearing system of force value, eliminating the factors of different error in reading table.

12, equipped with overload protection, when the force or displacement exceeds the rated theoretical value of the test machine, automatic unloading or stopping test.

13, destroy load and deformation value automatically collect and print reports.

14. The side shape is measured at the bottom end. The data is accurate and stable.

15. The microcomputer controlled hydraulic servo shaft cover pressure testing machine can be programmed by the user, automatic closed loop control, cyclic loading, loading speed and loading waveform according to the experimental needs. In a word, every index step of the national standard can be programmed, so that the whole process is automated without manual intervention.
