Microcomputer control fully automatic pressure tester for
compressive strength test of cement, concrete and rock
Brief introduction:
This machine is independently developed by our company, integrating
modern machine, electricity and liquid as a high-tech universal
automatic pressure testing machine. This machine adopts imported
oil pump, fast response, high control accuracy, the loading speed
of the user, the load sensor to fully ensure the accuracy and
reliability of test accuracy; the imported low noise high pressure
oil pump, can make the workplace has a quiet environment. The
hydraulic system uses a large fuel tank, suitable for a long time,
continuous operation. This series of test machine is suitable for
compressive strength test of cement, concrete and rock, with
special fixture and measuring device can meet the concrete split
pull test, folding test, static elastic modulus test; also can
apply to metal compression and top forging test; can expand
multiple displacement (or deformation) measuring channels according
to user requirements.
Hydraulic pressure system:
The hydraulic oil in the oil tank drives the high pressure pump
into the oil circuit through the motor, and flows through the check
valve, high pressure oil filter, differential pressure valve set
and servo valve, and enters the oil cylinder. The computer sends a
control signal to the servo valve to control the opening and
direction of the servo valve, so as to control the flow into the
cylinder and realize the control of constant speed test force.
Dynamometric system:
Using high precision amplifier and A / D converter, the whole
process is not graded, real-time display load, peak, loading speed
and strength;
The PID closed-loop control strategy is used to realize the
constant speed loading and display the loading curve in real time
Automatic interval timing and continuous test;
Query and printing test results are flexible and convenient.
