水泥全自動恒應(yīng)力抗折抗壓試驗機英文版本

Cement bending compression testing machine

Advantages of 2.1, the test force measurement range wider, more accurate and more stable: the electro-hydraulic servo control valve in the static control zero cover, cylinder seal and the frictional contact problems exist, so in the zero output near (displacement and stress test) is not linear and low speed easy crawling, poor stability, high starting pressure, unable to realize control output of small deformation and small test force (short age sample load is small, the control cannot be achieved) exists.

2, the test process of low noise.

3, the control process is not affected by the temperature, the performance is more stable.

4, no hydraulic oil run, run, drip, leakage caused by pollution problems. No servo valve pollution problems

5, long-term use of high reliability, maintenance free (no replacement of hydraulic oil is tedious).
