Manhole cover pressure testing machine, microcomputer control manhole cover pressure testing machine, multi-type manhole cover pressure testing machine

A microcomputer control manhole cover pressure testing machine product introduction

TDYE-JG series microcomputer controlled manhole cover pressure testing machine is mainly used to test the compressive performance of manhole cover and water well grate, and it can also test the bending performance after adding the bending test device (optional with it). This machine applies modern computer control technology, by wide speed range electro-hydraulic proportional servo valve, computer and measurement and control unit of the servo control system, can accurately control and measure the whole process of the test. The whole machine is composed of main engine, servo hydraulic source and computer measurement and control system. The test process is controlled by the computer program, which automatically measures, displays and processes the test data, and automatically edits the test report and prints it out. This machine uses special Chinese software for manhole cover test to realize professional testing of manhole cover.

Two, microcomputer control manhole cover pressure testing machine reference standard

The machine is based on CJ/T121-2000 "recycled resin composite material inspection manhole cover", CJ/T211-2005 "polymer matrix composite material inspection manhole cover", CJ/T3012-1993 "cast iron inspection manhole cover", JC889-2001 "steel fiber concrete inspection manhole cover", JC/T948-2005 "steel fiber mix Design and manufacture of the concrete water grate-lid, GB/T2611-2007 General Technical Requirements for Testing Machine, GB/T16826-2008 Electro-hydraulic servo Universal Testing Machine and other related standards.

Three, microcomputer control manhole cover pressure testing machine product characteristics

1, the host adopts high stiffness structure to ensure the safety in the test process.

2, the height of the worktable is 300mm, easy to take and put the manhole cover specimen.

3. The ball hinge connection is used between the rigid pad and the piston push out end to ensure the complete contact between the manhole cover and the reaction plate to ensure the authenticity of the bearing capacity.

4. The cylinder and piston are sealed with special materials to achieve the effect of high seal, low friction and long life.

5, the use of professional testing machine oil pump electric unit, low noise and long life.

6. Select superfine oil filter to ensure the cleaning of the oil circuit system so as to ensure the long-term work of the control actuator.

7, computer automatic control, real-time display of the current force value, peak, test process information, etc.

8, the test process real-time record test curve, high-speed sampling;

9, data, report processing function, provides users with graphics typesetting special report editing tools, has the characteristics of flexible operation, simple and easy to learn, can easily print test curve and test value;

10, the control mode has isokinetic stress, isokinetic test force, test force to maintain control functions and test force, peak, piston displacement, test curve screen display function, test curve force - time curve, force-deformation curve, deformation - time curve, control mode smooth conversion.

11, can need according to the experiment, users' programming, automatic closed-loop control, cyclic loading, the loading speed, loading waveform, (because of the standard loading process is a cycle of the waveform loading process) in short can be implemented gb step sequencing of each index, the full automation of the whole process without human intervention. See the legend for details.

12, the software set the force value automatic zeroing system, eliminate the human reading error and other factors.

13, with overload protection, when the force value or displacement exceeds the rated theoretical value of the testing machine, automatic unloading or stop the test.

14. Automatic collection of damage load and deformation value and print reports.
