When it comes to maintenance, many users feel it does not matter. People may think that it can be used without maintenance. This idea is wrong. It is very important for the maintenance of any test machine. It is a direct influence on the test results and the life of its equipment. Here we introduce the maintenance of the electronic universal testing machine.
The jaws are often used, easy to wear, if the oxide scale is too much, it will easily lead to damage to the small piston and cause oil leakage, so the jaws should be cleaned regularly, it is best to clean after each test to keep it clean;
Periodically inspect the screws at the jaws. If loosening is found, tighten them in time and check the transmission of the sprocket regularly. If any loose, please tension the tensioner again.
The fixture should be coated with antirust oil;
The sliding surface of the lining plate in contact with the lining plate and the dovetail groove surface of the lining plate shall be kept clean at all times, and a thin layer of molybdenum disulfide (MoS2) grease shall be regularly coated;
If you do not test for a long time, turn off the controller and computer. Regularly check whether the connection line of the rear panel of the controller is in good contact. If it is loose, fasten it in time. The interface on the plug-in controller must turn off the power of the controller. The interfaces on the controller are in one-to-one correspondence. The device may be damaged. If the machine is in standby mode, the changeover switch should be in the “load” position, because if the changeover switch is in the “rewind” position, the electromagnetic commutation valve is always on, which will affect the use of the device. life;
Check the leaks at the main engine and the oil source at regular intervals. If any oil leakage is found, replace the mat or seal, and replace the oil filter and filter element regularly according to the usage of the machine and the service life of the oil. Replace hydraulic oil.
