Universal testing machine, a materials testing machine that integrates functions such as tension, bending, compression, shear and hoop stiffness. It is mainly used to test the mechanical properties of metallic and non-metallic materials. Ideal testing facility for colleges, engineering quality control stations and other departments. Widely used in industrial production, scientific research and other fields, it plays a very important role.
It is used to test the properties of various materials, including static load, dynamic load, mechanical properties, elasticity, compressive strength, temperature resistance, etc. It can provide very important data for industrial production and scientific research.Therefore, there are many things to pay attention to when using universal testing machines, and it is also necessary to pay attention to the maintenance and upkeep of the equipment.
During normal operation of the universal testing machine, it is necessary to pay attention to daily maintenance and repairs. This is very necessary, so how can we maintain and maintain the universal testing machine?
One, universal maintenanceg of the main motor of the testing machine
(1) Regularly check the screws on the jaws of the universal testing machine and retighten them in good time if they are loose;
(2) The fixtures equipped with the universal testing machine should be smeared with anti-rust oil for storage;
(3) The paneled steel plate is in contact with the liner. The sliding surface and dovetail surface on the liner should be kept clean and a light coat of molybdenum disulphide grease should be applied periodically;
(4) Check the transmission regularly of the pinion, if it is loose, please tighten the tension wheel again;
(5) Because the jaws of the electronic tensile testing machine are often used, they are easy to carry, and if there are too many scales, the small plunger can be easy damaged and may leak oil, so it's best to clean it after each test;
Second maintenance of universal checkmachine control
(1) Regularly check whether the connecting wire on the back of the universal testing machine controller has good contact, and if it is loose, it should be time tightened;
2) Test If you don't use the machine for a long time, turn off the controller and the Universal Test Machine computer;
(3) The interfaces on the universal testing machine controller are in one-to-one correspondence, and the wrong interface may cause damage to the equipment;
(4 ) The controller must be switched off to plug and unplug the interface on the controller.
Three, Universal testing machineOil well maintenance
(1) Depending on the use of the universal testing machine and the life of the oil, periodically change the oil suction filter and filter element and hydraulic oil.
(2) Check regularlywhether oil is leaking from the main unit and the oil source of the universal testing machine. If oil leakage is found, the sealing ring or combination pad should be replaced in time;
(3) Pay attention to the usage time of the host power supply of the universal testing machine. When the machine is not running, the power switch should be turned to the load position to prevent the electromagnetic switching valve from being constantly on, which will directly affect the service life of the machine.
