This tester is mainly used for the compressive and flexural strength test of brick, stone, cement, concrete, ceramics, coal mine pellets and other construction materials, and also for the mechanical properties test of other materials. This machine adopts hydraulic loading, electronic force measurement, with load digital display, load rate display, load maximum value to maintain, as well as overload protection and power-off data retention and other functions. Implementation of GB/T 50081 standard.
1.Functional Use:
This tester is mainly used for the compressive and flexural strength test of brick, stone, cement, concrete, ceramics, coal mine pellets and other construction materials, and also for the mechanical properties test of other materials. This machine adopts hydraulic loading, electronic force measurement, with load digital display, load rate display, load maximum value to maintain, as well as overload protection and power-off data retention and other functions. Implementation of GB/T 50081 standard.
2.The Mechanical Part:
1.Space Adjustment Mode：
Through the handwheel rotation, the compression space adjustment is realized.
2.Hydraulic System:
The oil in the oil tank is sucked into the oil pump through the filtering oil net, and then sent to the oil delivery valve through the oil delivery pipe of the oil pump. When the oil delivery handwheel is closed, the piston will be pushed away due to the oil pressure, and the oil will flow back to the oil tank from the return pipe.
3.The Control System:
This machine adopts hydraulic loading, electronic force measurement, with load digital display, loading rate display, load maximum value keeping, and overload protection and power-off data keeping functions.
1.Safety Protection Device:
When the test force exceeds 3% of the maximum test force, overload protection, oil pump motor shutdown
