Basic operation method of tensile testing machine
Tensile testing machine is also one of the test equipment in the material testing machine. The tensile test (stress-strain test) of the tensile testing machine is generally to clamp the two ends of the sample on two clamps separated by a certain distance. The two clamps are separated and stretched at a certain speed, and the stress change on the sample is measured until the sample is broken. 1. When using the tensile testing machine, the equipment user must carefully read the technical manual, be familiar with the technical indicators, working performance, use methods, and matters needing attention, and strictly follow the prescribed steps in the instrument manual. 2. The staff who use the tensile testing machine for the first time must be operated by trained staff or under their guidance, and can operate independently only after being proficient in grasping it. 3. Tensile testing machines and other equipment used in the experiment should be placed neatly, easy to operate, observe and record. 4. Before the tensile testing machine is energized, make sure that the power supply voltage meets the specified input voltage value of the tensile testing machine. The tensile testing machine equipped with a three-wire power plug must be plugged into a power supply socket with grounding protection and can only be operated after ensuring safety. 5. When using a tensile testing machine, its input signal or external load should be limited within the specified range, and overload operation is prohibited. 6. u200bu200bBefore using the tensile testing machine, it must be operated without load to ensure that there is no fault before loading and using. Lubricate before use, wipe clean after use, pay attention to daily maintenance and maintenance. 7. Tensile testing machine can not be disassembled or disassembled for use at will. 8. Frequently maintain the tensile testing machine and store it in a dry and ventilated place. If the tensile testing machine is not used for a long time, it should be powered on regularly to prevent moisture and mildew from damaging the parts of the tensile machine. 9. The limit switch of the tensile testing machine must be adjusted carefully to protect the sensor from collision.
