Do you know how to debug the test machine?

Electronic computer type universal material testing machine is suitable for tensile testing of rubber, plastics, textiles, waterproof materials, wires and cables, net ropes, metal wires, metal rods, metal plates and other materials. Additional accessories can be used for compression, bending, and ring Stiffness test. The following Jinan Times Testing Machine Technology Co., Ltd. will bring you the installation and commissioning method of computer-type universal material testing machine.

1. The computer-type universal material testing machine is installed in a clean, dry, vibration-free room with a room temperature of 20 ° C ± 10 ° C. It is noted that the beam bending test, the use of an extensometer for testing, and the maintenance of equipment are all around the testing machine. Leave enough free space. For the specific steps of installation, the main body and force measuring device of the computer-type universal material testing machine should be installed on the concrete foundation. The basic dimensions are based on the shape and foundation diagram, leaving the foundation screws and lower jaw screws. Holes and other electrical installations such as pipes. The upper plane of the foundation should be flat, use a spirit level to align it, and after the foundation is dry, install a computer-type universal material testing machine.

2. Then the computer-type universal material testing machine takes over. When installing the oil pipe communicating with the force measuring device, the inside of the oil pipe should be washed with kerosene first to ensure the cleanliness in the oil circuit. Attention should be paid to the integrity of the joint gaskets to prevent oil leakage under high pressure. The computer-type universal material testing machine is connected to the electrical work. The electrical device of the computer-type universal material testing machine is in the force measuring device. The power supply is a three-phase four-wire system. The circuit between the main body and the force measuring device is connected by a plug. The dust and other impurities in the electrical box are cleaned up. After the power cord is introduced, press the "Power" button on the force measuring device table panel to light up to prove that power has been started. At this time, you can press the oil pump start button and observe the direction of motor rotation. Then press the lifting button of the jaw base, check whether the lifting action of the lower jaw base is consistent with the text shown on the button, and at the same time check whether each limit is the switch.

3. After installing the computer-type universal material testing machine, you should learn how to correct it. The first is the installation and preliminary accuracy of the computer-type universal material testing machine. The main body and the force measuring device are transferred to the concrete foundation. Shape and foundation map Adjust the distance between the main body and the force-measuring device and adjust the direction. Then use a small piece of iron to insert the bottom of the main body and the force-measuring device (between the foundation), with an accuracy of 0.05 / 1000. The square spirit level can be calibrated separately; the preliminary alignment of the main body can be measured with the square spirit level at two different positions of the vertical and horizontal positions of the two columns. The plumbness must not be greater than 0.3 / 1000. Then, the square spirit level can be used to lean against the outer surface of the cylinder. And vertical and horizontal positions of the vertical alignment. Second, the accuracy of the computer-type universal material testing machine is calibrated. After the preliminary accuracy of the testing machine is calibrated as above, the oil pipe, power supply and oil filling are connected to perform the initial test run. When the test run is in good condition, the test machine is then calibrated. Correct the accuracy so that the error must not be greater than 0.10 / 1000. After that, fill all the gaps under the machine base with cement slurry to keep the machine base and the cement foundation in good condition to prevent the test machine from being level due to vibration during use.
