What is the maintenance process of the tensile testing machine

Tensile testing machine is also known as universal material testing machine. The universal testing machine is a mechanical testing machine used for static load, tension, compression, bending, shear, tearing, peeling and other mechanical performance tests of instruments and equipment for various materials. Let's share with you the maintenance process and force calculation method of the tensile testing machine.
1. Maintenance process of tensile testing machine


1. Regularly check the screws at the jaws of the jaws, and tighten them in time if they are found to be loose.

2. The sliding surface of the inlaid steel plate and the liner plate and the dovetail groove surface of the liner plate should be kept clean, and a thin layer of MoS2 (molybdenum disulfide) grease should be applied regularly.

3. Regularly check the transmission of the sprocket, if any looseness is found, please re-tension the tensioning wheel.

Oil source maintenance

1. Regularly check whether there is oil leakage at the main engine and oil source. If oil leakage is found, replace the sealing ring or combination gasket in time.

2. According to the use of the machine and the life of the oil, regularly replace the suction filter and filter element, and replace the hydraulic oil.

3. When not doing the test for a long time, pay attention to turn off the power of the host. If the machine is in the standby state, the transfer switch should be set to the "load" position, because if the transfer switch is set to the "fast reverse" position, the solenoid valve is always energized, which will affect the service life of the device.

Tensile testing machine control system maintenance

1. Regularly check whether the connection line between the measurement and control card and the testing machine is in good contact. If there is any looseness, it should be tightened in time.

2. After the test, if the machine is not used for a long period of time, turn off the computer and pull out the measurement and control card.

3. The interfaces on the controller are in a one-to-one correspondence, plugging the wrong interface may cause damage to the device

4. The power of the controller must be turned off when plugging or unplugging the interface on the controller.

5. According to the use of the machine and the life of the oil, regularly replace the suction filter and filter element, replace the hydraulic oil, and regularly check whether there is any oil leakage at the main engine and the oil source. If any oil leakage is found, the sealing ring should be replaced in time Or combination mat
