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.
