Portable Cement Strength Tester;compression machine
Brand SYHK
Certification N/A
The portable cement strength tester produced by Applied Technology Research Institute of Shenyang Aerospace University is an automatic uniform loading pressure tester. It is designed and manufactured in strict accordance with the specification 10A of API and GB 10238-2005 standard and mainly used to measure the compressive strength of oil well cement. Measurement method: apply force on oil well cement sample at constant speed till the sample is crushed. The measured load (the force per unit area) at the time of crushing of oil well cement sample is the compressive strength of oil well cement. The cement strength tester adopts PLC as the main controller. PID classical control technique is used to control electro-hydraulic proportional valve, so that the pressure tester is able to apply force on samples at a constant speed. Functional Characteristics Protection function: dual overpressure protection of electro-hydraulic proportional valve and overflow valve; Manual test:test samples (1-4 blocks) group by group, the tester will descend automatically after a sample is crushed, and then manipulate manually the tester to test the next sample, and on and on, and the tester will conduct data clearing till the 4 samples are tester, manual data clearing is also available; Data and curve: the touch screen can display the test data and curve as well as input them to U disc directly and print the data and curve; Man-machine interaction interface, visual and easy operation.
Technical Parameters:
