Application:
This compression testing machines is computer control. And just can done the test with the constant
speed loading. It is can used just after made the machine smoothly
and level. It is mainly used for rock, concrete, cement products,
hollow bricks, fly ash bricks, refractory materials, engineering
materials, stone, rubber bearing compressive strength test and
other building materials.
It is a necessary testing machine for the highway, railways,
bridge, building materials and other laboratory.
1. Application
compression machines is mainly used for
brick, cement, concrete, construction material and othermaterial
compression resist testing. Widely used in metallurgy, building
materials, space flight and aviation, colleges and universities,
R&D institution lines. The test operation and data processing
meets standard requirements.
2. Product description:
* Structure:mainly composed by main unit, oil source and measuring control
system.
*Space adjusting way: Electric ball screw adjusting to realize the compression space
adjusting
* Measuring control system:The machine adopts hydraulic loading, the electronic testing load.
With digital display load, loading rate, keeping maximum load,
overload protection and outage data keeping and other.
* Safety protection device:When the test foce exceed the 3% of the
maximum test force ,overload protection, the oil pump motor stop.

Equipment overview:
compression machines is with closed-loop force control of electric hydraulic pressure
testing machine, with constant control and load holding function,
adopts imported servo valve, quick response, high control
precision, in allowing the machine, the user can according to the
test requirements of any set of loading rate; force measuring
system using load sensor, and fully guarantee the precision test is
accurate and reliable; the imported low noise high pressure oil
pump, can make the workplace with a quiet environment. The
hydraulic system adopts air cooling device for a long time. The
series testing machine is suitable for cement, concrete and rock
compressive strength test. The test method can meet the splitting
tensile test, bending test and static elastic modulus of concrete.
Meet standards:
Test method for 7314-2005 GB/T metal materials at room temperature
Strength test method (ISO) for 17671-1999 GB/T cement mortar
