JAW series microcomputer control covers pressure testing machine

Testing machine is mainly used for manhole covers and grates compressive performance tests, increasing the bending test device (optional accompanied) was also carried out anti-bending performance test. The application of modern computer control technology, servo control system comprises a wide speed range of electro-hydraulic servo valve and proportional control unit consisting of a computer and can accurately test the entire process control and measurement. By the part of the host machine, the servo hydraulic pressure source, computer monitoring and control system components. During the test, automatically measured display, processing test data, automatically edit and print out the test report by the computer program control, Native machine application covers test special Chinese software, professional testing of wells.

According to CJ/T121-2000 Composite material inspection well lid of regenerated resin, CJ/T211-2005Inspection manhole lid made of polymer matrix composites, CJ/T3012-1993Cast iron manhole top, JC889-2001Steel fiber reinforced concrete checking well cover, JC/T948-2005Steel fiber reinforced concrete water outlet cover, GB/T2611-2007General requirements for testing machines, GB/T16826-2008Electro-hydraulic servo universal testing machines.

With a test force, displacement of the two control channels and the corresponding test force thereto, between stress and displacement three control modes, control can be random / arbitrary switching; PID control parameters can be adjusted online.

Carried out constant speed test force, uniform stress and constant displacement constant speed test.

You can complete a variety of wave loading cycle test according to the set low weeks.

System with automatic zero, automatic calibration, continuous full measure, variable speed and other functions

The host takes underneath type oil cylinder, four column beam structure. Car structure is used to press table for sample loading and unloading, press table for spherical support and pressure on the beam forming compression test space

The beam center position with circular opening for easy testing process to measure water grate cover the crack.

Random configuration a variety of specifications of rigid block and rubber pad.
