Our tensile testing machine integrates automatic control, automatic measurement, data acquisition, screen display and test result processing. The main engine platform under the oil cylinder is equipped with precision oil pump, imported electro-hydraulic proportional valve and PC servo controller. Realize multi-channel closed-loop control, complete the automatic control and automatic measurement function in the test process. It has the characteristics of good professionalism, high reliability and easy to upgrade. It can be enriched and improved with the development of measurement and control technology and the change of test standards. It is mainly suitable for tensile, peel, tear, compression, bending and shear tests of metal and nonmetal materials. The load value, displacement value, deformation value, test speed and test curve are dynamically displayed by large screen LCD. The test results can be saved automatically, and the test curve can be called after the test.

How to operate the tensile testing machine for nonmetal materials;

1. First check whether the data line and power line are connected normally, turn on the control microcomputer, start the measurement and control software of the testing machine, edit the test data, then press the "power" button of the control cabinet, the indicator light will be on, and then the oil pump motor will start. At this time, don't rush to do the test, but preheat the oil circuit of the pumping station system, and start to use about 1 minute later.

2. Load the corresponding jaw according to the diameter or size of the sample. A set of hydraulic press jaw is divided into four pieces, two pieces up and down. At this time, a small amount of molybdenum disulfide grease should be added between the jaw and jaw splint.

3. When clamping the sample, first clamp one end of the sample on the upper jaw of the testing machine, then click the clamping button of the manual control box, then select the appropriate speed, and click the beam lifting button to make the middle beam rise and clamp it in the shallow hole of the lower part. In this step, we should pay attention to the distance between the shallow mouth and the jaw.

4. Select the appropriate test speed, reset force value, displacement, time, etc. in the measurement and control software of the control microcomputer, and then click the test button. At this point, the display curve begins to draw and the test begins.

5. With the increase of the test force, the test curve will also show an upward trend with the increase of the force value, until the metal material begins to decline after yielding, which indicates that the sample is about to fracture, so pay attention to observe until the end of the test.

6. After the test, the experimental report will pop up automatically, and the required test results will be printed and saved.
