used concrete compression test machine

 concrete compression test machine  

Confirm to the standard:

     GB/T2611 General Technical Requirements for Testing Machine,

     GB/T16826 Electric-Hydraulic Servo Universal Testing Machine,

     GB/T3075 Metal Axial Fatigue Testing Method, 

     JB/T9379 Technical Conditions of Pulling Pressure Fatigue Testing Machine,

     GB/T228 Method of Tensile Test under for Metal Material Room Temperature etc.

  Features:

1. Host machine: two stand columns, base and beam constitute closed frame structure with

    strong rigidity and good stability, without reverse gap. The external surface of the double

    stand columns adopts electroplating hard chrome processing. Servo actuator (oil cylinder)

    is underlying and adopts bidirectional oil cylinder piston design so that sample clamping

    adjustment could be flexible and easy.

2. Hydraulic-servo pump station: adopts leak-free mute technology. Pressure could be exported

    stably without fluctuation and with low noise, good dissipation, high filtering accuracy, and

    automatic protection ability when pressure overloads and oil temperature overheat.

3. Key components: adopt internationally renowned brand-Italian ATOS servo valve, American

    LVDT displacement sensor and American TRANSCELL high-accuracy loading component.

4. Control mode: power, displacement and deformation PID closed loop control which could

    achieve smooth handover under any control mode.

5. Testing software: is applicable for Windows XP/Windows7operating system, owns the

    functions of setting test method, managing storage means, saving testing data automatically

    and printing test report etc.

6. Testing waveforms: sine wave, square wave, triangular wave, trapezoidal wave, oblique wave,

    zigzag wave and user-defined wave etc.

7. Protection function: to set alarm and stop function when oil-way is blocked and overheats,

    liquid level is low, hydraulic system overloads, electrical machine overheats, preset number

    of fatigue is reached and sample fractures etc.

Specification(working condition):

1. Ambient temperature: 15~30°C

2. Relative humidity: ≤85%

3. Power supply: AC380V 50Hz three-phase five-wire system, configuration of principal line shall

    meet the demand of 15KVA.

4. The device shall be installed on solid and horizontal ground. Levelness of the testing machine:

    0.2/1000; weight capacity of ground: three times the weight of device

5. When using the device, there shall not be vibration, corrosive medium, strong magnetic

    interference but ventilation shall be good.

6. Clients shall provide 52# anti-abrade oil for themselves as well as cooling water: flow>6m3/h,

    cooling water pressure>0.6Mpa.
