Electro-hydraulic Concrete Compressive Strength Testing Machineis mainly used for brick, stone, cement, concrete and other building materials, compressive strength test,also used to test the compressive
erformance of other materials.
Spatial adjustment method:Through the hand wheel rotation, the adjustment of space to achieve compression.
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:
Electro-hydraulic Concrete Compressive Strength Testing Machineadopts hydraulic loading, electronic measuring
force, with a load of figures, the loading rate shows,the maximum load to maintain, as well as overload protection and power data retention and other functions.
Safety protection device:
When the test force more than 3% of the Max. test force, the overload protection, oil pump motor shut down.
Fixture:
Whole set fextures include: a set compression platen fixture
