Product Introduction: ,
The microcomputer controlled rock intrusion hardness testing machine is mainly used to measure the hardness and plasticity coefficient of rocks. Automatically draw stress-strain curve, force-deformation curve, force-displacement curve, force-time curve, deformation-time curve, displacement-time curve, force-strain curve. With the function of partial amplification of test curves and superposition and comparison of multiple curves, it is an essential test equipment for studying rock drillability in petroleum, exploration and other industries.
This machine consists of a host machine, a servo motor, a ball screw column, a cross beam, an upper pressure head (pressure plate), and a lower pressure plate. It can fix the displacement sensor, pressure sensor, pressure head (pressure plate) and rock test Sample. The cylindrical indenter (pressure plate) is made of high-strength steel and then embedded with a carbide cone. The carbide cone is ground into a cylinder (dimensions as shown in the figure) d=.~.so that the indenter (pressure plate) The contact area with the rock always remains unchanged, which facilitates the calculation of the rock's compression and ultimate strength-hardness values. The two ends of the indenter (pressure plate) are required to be absolutely parallel. The cemented carbide should be inserted vertically into the embryo body. The accurate data of the diameter of the ground cylinder must be measured with a reading microscope.
Pressurization system: AC servo motor drives the ball screw to rotate the ball screw to drive the cross beam to descend. The pressure head (pressure plate) fixed on the cross beam performs a pressure test on the rock sample on the lower pressure plate. The force sensor displays the force value. pressure.
. Displacement meter: Double extensometers (displacement sensors) are fixed on both sides of the beam indenter (pressure plate) of the hardness tester and used to measure the depth of the stamper pressed into the rock sample. The machine uses dual extensometers (displacement sensors) to measure the displacement change, mainly to average the displacement errors to make the displacement change more accurate.
, Data measurement and control card and software processing system: The measurement and control card collects the signals transmitted by the force sensor and extensometer (displacement sensor) and then imports the signals into the testing machine data processing software. The processing software draws the stress of the rock based on each signal data. -Strain curve and calculate the hardness and plasticity coefficient of rock.
