The electronic universal testing machine is widely used in the tensile, compressive, bending and shearing mechanical performance tests of metal and non-metal materials. This product is widely used in tensile, compressive, bending and shearing mechanical performance tests of metal and non-metal materials. With a wide range of accessories, it can also be used for the mechanical performance test of profiles and components. It also has a very wide range of application prospects in the field of material testing such as rope, belt, wire, rubber, and plastic with large sample deformation and fast testing speed. It is suitable for testing fields such as quality supervision, teaching and research, aerospace, iron and steel metallurgy, automobiles, construction and building materials.
The computer system of the electronic universal testing machine controls the rotation of the servo motor through the controller and the speed control system. After deceleration by the deceleration system, the moving beam is driven up and down by the precision screw pair to complete the stretching, compression, bending and shearing of the sample. And other mechanical performance tests. Daily maintenance is of great significance to ensure the normal operation of the equipment and measurement accuracy. Because this product is a high-precision testing instrument, daily maintenance and maintenance can achieve better results.
Mainframe maintenance of electronic universal testing machine:
1. Regularly check the screws at the clamp, and tighten them if the screws to be loose.
2. The clamp equipped with the machine should be coated with anti-rust oil for storage.
3. Regularly check the transmission of the sprocket. If there is any looseness, please re-tension the tensioning wheel.
4. Since the jaws of the universal testing machine are often used, they are easy to wear. If there are too many oxide scales, it is easy to cause the small piston to damage and leak oil. Therefore, the jaws should be cleaned frequently and kept clean (generally clean after each test).
5. 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.
Maintenance of the oil source of the electronic universal testing machine:
1. 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.
2. 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.
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 electromagnetic directional valve is always energized, which will affect the service life of the device.
Electronic universal testing machine control system maintenance:
1. The interfaces on the controller are in one-to-one correspondence, plugging the wrong interface may cause damage to the device.
2. If the machine is not used for a long period of time after the test, turn off the controller and computer.
3. Regularly check whether the connecting wire on the rear panel of the controller is in good contact, if it is loose, it should be tightened in time.
4. The power of the controller must be turned off when plugging or unplugging the interface on the controller.
