Product Information

The oil well cement pressure test machine produced by the Applied Technology Research Institute of Shenyang Aerospace University is automatic uniform loading pressure tester and mainly used to measure the compressive strength of oil well cement. It is designed and manufactured in strict accordance with the specification 10A of American Petroleum Institute (API) and GB10238-2005. It can apply stress on oil well cement sample at a 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. Functional Characteristics Maintenance-free during its service life; Stable loading process, small noise (smaller than 65 db); High control and measurement accuracy, easy operation; Fixed point or multiple point calibration, more accurate calibration; The collection software can record, store and print the test data as well as display and print real-time curve; Touch screen is used as the man-chine interaction interface, more visual and easy to operate; Protection function: dual overpressure protection of electro-hydraulic proportional valve and overflow valve; Automatic test: users may set the number of test samples (1-4 samples), the machine will descend automatically after a sample is crushed, and then ascend automatically for to test the next sample, and on and on, the tester will stop automatically till all samples are crushed; Data and curve: the touch screen can display the test data in real time and use PC to store test data and print data and curve at the same time.
