Do you know how to debug the tensile testing machine

1. The tensile machine should be placed in a clean, dry, vibration-free room with a room temperature of 20°C ± 10°C. Pay attention to beam bending tests, extensometer tests, and equipment maintenance, leaving enough space around the testing machine. In the specific steps of setting, the main body and dynamometer of the tensile machine should be set on the foundation of concrete, and the size of the foundation should be according to the regulations of the shape and the foundation drawing, leaving holes for the anchor screws and lower jaw screws and other wires for setting piping etc. device. The upper plane of the foundation should be flat, use the level ruler correctly, and install the tension machine after the foundation is dry.

2. After installing the tensile testing machine, you should learn how to do it correctly. The installation and preliminary accuracy of the tensile testing machine are correct, transport the main body and the measuring instrument to the concrete respectively, adjust the distance between the main body and the measuring instrument according to the shape and foundation map, adjust the direction, and insert the main body and the measuring instrument with thin iron blocks respectively. The lower part (between the foundation), use a square level with 0.05/1000 precision to correct the preliminary correctness of the main body can be measured with a square level at two different positions in the vertical and horizontal directions of the two columns, and the verticality shall not exceed 0.3/1000. Then, you can use a square level to find the lead in the horizontal and vertical positions of the level.

3. The precision of the tensile testing machine is correct. After the initial precision of the above testing machine is correct, turn on the oil pipe, power supply and oil filling to carry out the preliminary running test. After the test condition is good, the precision of the tensile testing machine is correct, and the error shall not exceed 0.10/1000. After that, fill all the gaps under the seat with cement slurry to keep the seat well combined with the cement foundation to prevent the testing machine from being leveled due to vibration during use.

4. The tension testing machine is connected to the pipe. When the main body passes through the pipe of the dynamometer, please clean the inside of the pipe with kerosene first to ensure the cleanliness of the pipe. Attention should be paid to the integrity of the gasket to prevent oil leakage under high pressure. The tensile testing machine is connected to electricity. The electrical equipment of the tensile testing machine is in the dynamometer. The power supply is three-phase four-wire system. The circuit between the host and the dynamometer is connected by a plug. After the impurities are introduced into the power cord, press the power button on the panel of the tensile testing machine to indicate that the power supply has started. At this time, press the start button of the oil pump to observe the rotation direction of the motor. Whether the lifting action is consistent with the text displayed by the button.
