When using the universal testing machine on a daily basis, it is very beneficial to pay attention to some small details, which is beneficial to maintain the superior performance of durability and good use. Maintenance of the universal testing machine can start from the following aspects:
1. All parts of the testing machine should be wiped clean frequently. Wipe off the surface without painting and apply a small amount of oil to the cotton yarn to prevent rust. During the rainy season, you should pay attention to wiping. When not in use, cover it with a dust cover. Dust-proof soil intrusion.
2. All the valves on the control cabinet should not be opened to prevent dust from entering the interior, which affects the sensitivity of the measuring mechanism.
3. Long-term frequent use may result in reduced or degraded oil quantity. The oil quantity should be checked every 1-3 months according to the usage. After the equipment has stopped running for 15 minutes, observe the left side oil window of the control cabinet. If the oil level is lower than the oil window, add the same type of hydraulic oil to the middle position of the oil window; if the oil has deteriorated, replace it with new hydraulic oil.
4. Frequent use of this equipment for tensile breaking test may cause some fasteners to loosen. The fastening of the following parts should always be checked:
a. The upper beam and the moving beam have two (a total of 8 pieces) L block pressure plates (the jaw plate guide function), and each pressure plate is fixed by 2 screws;
b. Move 6 screws at each end of the beam;
c. Check the tightness of the screw drive chain every 6 months, and adjust the position of the tensioner wheel accordingly (after removing the lower part of the main body);
5. Lubricate the following parts every 3~6 months according to the environmental conditions and frequency of use:
a. The joint between the screw and the base is lubricated with 100 oil;
b. The screw drive chain is lubricated with butter;
c. The screw part of the screw is kept clean and lubricated with butter or molybdenum disulfide;
Both ab lubrications need to be removed after removing the lower part of the main body.
6. There are two jaw clamps for the jaws on the upper beam and the moving beam. It is an important part of the machine. The debris on the contact surface between the jaw plate and the beam should be removed frequently to avoid pulling the hair. Contact surfaces. The method is: remove the pressure plate on one side of the moving beam, take out the jaw plate, and clean the contact surface of the jaw plate and the beam with an oil rag, apply a proper amount of grease and graphite mixed grease, and replace the jaw card. After tightening the fixing screws of the pressure plate.
