The maintenance method of universal testing machine

The universal testing machine is widely used in a variety of metals, non-metals, composite materials, medicine, food, wood, copper, aluminum, plastic profiles, electrical wires and appliances, paper, film, rubber, textiles, aerospace, and other industries for tensile properties according to the standard test, while according to the user to provide a variety of domestic and international standards customized test data processing software and test aids. Universal testing machine to ensure efficient operation, you need to pay close attention to the working condition of the equipment and do the necessary maintenance work. The following are some of the introductions.

Here is the content list:

Host maintenance

Universal testing machine with the fixture should be coated with anti-rust oil storage. As the universal testing machine jaws are often used, easy to wear, too much oxide, easy to cause small piston damage oil leakage, so the jaws should be cleaned frequently to keep clean. The sliding surface of the steel plate and the liner plate connected, the dovetail groove surface on the liner plate should be kept clean and regularly coated with a thin layer of MoS2 (molybdenum disulfide) grease.

Control system maintenance

Regularly check the universal testing machine controller back panel connection line is in good contact. If there is loosening, should be tightened in time. After the test, if there is a long period without the universal testing machine, the controller and computer need to be closed. The interface on the controller is one by one, inserting the wrong interface may cause damage to the equipment. Plugging and unplugging the interface on the controller must turn off the controller power.

Other matters

Regularly check the screws in the jaw area, and tighten them in time if they are found to be loose. Regularly check the transmission of the sprocket, if found loose, please re-tension the tensioning wheel. Also regularly check the mainframe of the universal testing machine and the oil source at the type of whether there is oil leakage if found to have oil leakage, should be timely replacement of seals or combination of gaskets. According to the use of a universal testing machine and the use of the oil period, regularly replace the oil suction filter and filter element, replace the hydraulic oil. When not doing experiments for a long time, pay attention to turn off the host power. If the universal testing machine is in standby mode, the transfer switch should be played to the "load" file, because if the transfer switch is played in the "fastback" file, the electromagnetic reversing valve has been in the energized state, which will affect the service life of the device.

Nanjing T-Bota Scietech Instruments & Equipment Co., Ltd reminds you that, after understanding the use of universal testing machine precautions and maintenance, the operator in the use of universal testing machine must be used by the manual process specification. Otherwise, it is easy to cause the failure of the universal testing machine and personnel injury and other dangerous situations. If you are not clear, contact us.
