Host:

Adopt oil cylinder under mounted type host, stretching space is at the top of host, compression test space is between the at the work table and the crossbar .

Transmission System:

Down beam go up and down by the use of motor reducer, chain drive mechanism, vice screw drive, to achieve tensile, compression of space to adjust.

Hydraulic System:

The oil tank is sucked through the filter screen and be inhaled pump oil ,through the petroleum pipeline of oil pump transport to oil valve,When the hand wheel to send off the oil, due to the role of oil will push the piston, the oil from the return pipe to tank, when the hand wheel to open get the oil, then the working fluid into the fuel tank through the tubing, pressure tubing through and through oil return valve to tank.

Control System:

Electronic force measurement, liquid crystal display test force time curve, test power, peak test power, has obvious characteristics of the material yield strength yield the experimental data easy and intuitive;Through digital button input sample numbers, cross-sectional area, can be directly measured the material tensile strength,yield strength and other mechanical properties;can query the experimental results,print (with micro-printer)

Safety Protection Device:

a) When the test force more than 3% of the maximum test force, the overload protection, oil pump motor shut down.

b) When the piston rises to the upper limit position, stroke protection, pump motor shut down.

Fixture:Whole set fextures include:stretch fixture,compression fixture,bending fixture.
