1, make the main switch to turn on the power.
2, according to the specimen, the choice of measurement range, on the pendulum hanging or remove the pendulum thallium and adjust the buffer valve handle, aligned with the mark.
3, according to the specimen shape and size of the corresponding chuck into the upper and lower jaw seat.
4, in the depiction of the cylinder, roll pressure good record paper (grid paper), this is only when necessary.
5, open the oil pump motor, unscrew the oil delivery valve so that the test bench to rise paper 10 mm, and then close the oil valve, if the test bench has been in the rising position is not necessary to open the oil pump to send oil, only the oil delivery valve can be closed.
6, the specimen end of the clamp in the upper jaw.
7, start the oil pump to adjust the pointer to the zero point of the dial.
8, open the lower jaw motor, the lower jaw lift to the appropriate height, the specimen will be the other end of the clamp in the lower jaw, must pay attention to make the specimen vertical.
9, will put down the pencil on the push rod to enter the portrayal of the preparatory state (need to be portrayed only when carried out).
10, according to the test requirements of the loading speed, slowly unscrew the oil delivery valve for loading test.
11, the specimen breaks off the oil valve, and stop the oil pump motor.
12, record the required value and will depict.
13, open the oil return valve, unloading after the passive needle dialed back to zero.
14, remove the broken specimen.
15, compression and bending test can refer to the above items to operate.
Universal testing machine, tensile, bending, compression, shear, ring stiffness and other functions in one of the material testing machine, mainly used for metal, non-metallic materials mechanical properties test, is the industrial and mining enterprises, scientific research units, universities and colleges, engineering quality supervision station and other departments of the ideal testing equipment. Universal testing machine is also called universal material testing machine, or tensile machine, double screw series, control, measurement, operation of the integrated structure, integration of contemporary advanced technology in one, with high precision, wide speed range, compact structure, easy to operate, stable performance and other advantages. Electronic universal testing machine to meet the GB/T1040, 1041, 8804, 9341, 9647, ISO7500-1, GB16491, GB/T17200, ISO5893, ASTMD638, 695, 790 and plastic pipe and other standards. Applicable to plastics, waterproof materials, textiles, paper products and rubber and other material samples and products of the tensile, compression, bending, creep test and equipped with a large platen can be directly carried out pipe flat compression (compression recovery), ring stiffness (resistance to external loads), creep ratio, the ring tensile strength and other tests.
