EHC-5000 System for Electro-Hydraulic Servo Compression-Shear Testing Machine

EHC-5000 system compressive-shear testing machine
 
The EHC-5000 measure and control system is suitable for upgrading and reconstructing the hydraulic compression-shear testing machine to computer control electro-hydraulic servo plate-type rubber bearing compression-shear testing machine.

It works with high precision and good reliability, fully meets the test requirements of road and railway rubber plate bearing, tub-type bearing from GB, ISO, ASTM and other standards.
 
  • Our EHC-5000 system is able to conduct the compressive elasticity modulus test, shear elasticity modulus test, shear bond performance test, ultimate compressive strength test, friction coefficient test, allowable angle test, tub type vertical bearing capacity test, tub-type friction test, shear aging test and so on.
  • The system uses high-performance digital servo valve, has the force closed-loop control function. It is availble to achieve the constant load rate loading or constant stress rate loading.
  • The rubber bearing test meets the related national standard requirements of JT/T4-2004, JT 391-1999, JT3132.3-90, JT/T4-93.
  • Suitable to work with Windows 9x, 2000 and XP operation system.
  • Using high-precision amplifier and A/D converter. The effective inner code is ± 200000. Working with stepless variable speed and grade one precision. Digital display load, deformation, loading speed and compressive strength in real-time.
  • The high-precision grating micrometer is used to measure the axial and radial deformation of the specimen. The grating micrometer has the minimum scale of 0.001mm, maximum indicating value error ≤0.003mm, Indicating value repeatability error ≤0.001mm.
  • Using high precision grating ruler to measure shear deformation of the specimen. The grating ruler has the minimum scale of 0.001mm, maximum indicating value error ≤0.005mm, indicating value repeatability error ≤0.003mm.
  • Using computer to implement electronic measurement, automatically accomplish the servo loading control and automatically calculate test results and print the reports.
  • Uses PID closed-loop control strategy to implement constant speed pressurizing, constant speed decompressing and pressure holding.
  • Display the loading curve and stress-strain curve in real time.
  • There are two types of control modes: automatic loading and manual loading.
  • Using standard database to manage the test data.
  • Test force overload protection.
