The Significance and Maintenance of Routine Maintenance of Bag Rally Tester
Daily maintenance is of great importance to ensure the normal operation of equipment and measurement accuracy. Mainly based on the host, oil source, and maintenance of the control system:
First, the host maintenance:
1. The fixtures provided with the machine should be coated with antirust oil ;
2 , due to the jaws of the tester is often used, easy to wear, too many oxide scales, easily lead to small piston damage and oil leakage, so the jaws should always be cleaned and kept clean ( preferably every time after the test is cleaned );
3 , the sliding surface of the inlaid steel plate and the liner plate, the dovetail groove surface of the liner shall be kept clean, and a thin layer of MoS2 ( molybdenum disulfide ) grease shall be regularly coated ;
4. Regularly check the screws at the jaws. If loosening is found, tighten them in time .
5. Regularly inspect the transmission of the sprocket. If any looseness is found, please tension the tensioner again ;
Second, control system maintenance:
1. Regularly check whether the connection line of the rear panel of the controller is in good contact. If it is loose, tighten it in time .
2. If the machine is not used for a long time after the test, turn off the controller and computer ;
3. The interfaces on the controller are in one-to-one correspondence. Inserting and inserting the wrong interface may cause damage to the equipment .
4. The interface on the plug-in controller must turn off the controller power.
Third, the maintenance of oil sources:
1 , regularly check the host and the oil source at the place where there is oil leakage. If any oil leakage is found, the seal ring or combination pad should be replaced in time ;
2. According to the usage of the machine and the service life of the oil, replace the oil filter and filter element regularly to replace the hydraulic oil.
3 , when not testing for a long time, pay attention to turn off the host power supply. If the machine is in standby mode, the changeover switch should be in the "load" position, because if the changeover switch

Daily maintenance of excavator hydraulic cylinders
The hydraulic cylinder of an excavator is one of the important hydraulic components responsible for driving and controlling mechanical movements. In order to ensure the normal use of hydraulic cylinders and extend their service life, daily maintenance is necessary.
1. Regularly clean the hydraulic cylinder: During use, the hydraulic cylinder will be attacked by various pollutants, such as dust, sediment, oil stains, etc. These pollutants can affect the working efficiency and lifespan of the hydraulic cylinder. Therefore, it is necessary to regularly clean the hydraulic cylinder.
2. Regular inspection of seals: The seals of hydraulic cylinders are key components to ensure their normal operation. If the seals are damaged or worn, it can lead to oil leakage or unstable operation of the hydraulic cylinder. Therefore, it is necessary to regularly inspect the sealing components of the hydraulic cylinder and replace them in a timely manner if there is any damage or wear.
3. Regular inspection of hydraulic oil: The operation of hydraulic cylinders requires the support of hydraulic oil, so the quality of hydraulic oil has an important impact on the working effect of hydraulic cylinders. Regularly check the quality of hydraulic oil, and replace it promptly if there is contamination or deterioration.
4. Regularly check the hydraulic pipeline: The hydraulic pipeline is the blood vessel of the hydraulic cylinder. If there is oil leakage or damage to the pipeline, it can cause the hydraulic cylinder to not work properly. Therefore, it is necessary to regularly inspect the hydraulic pipelines and promptly repair or replace them if there is any oil leakage or damage.
5. Regularly lubricate the hydraulic cylinder: The piston rod and piston ring of the hydraulic cylinder need to be lubricated to reduce wear and friction. Therefore, it is necessary to regularly apply lubricating oil to ensure the normal operation of the hydraulic cylinder.
In short, the daily maintenance of excavator hydraulic cylinders is very important, which can extend their service life and improve work efficiency. Regular cleaning of hydraulic cylinders, inspection of seals, hydraulic oil, hydraulic pipelines, and lubrication of hydraulic cylinders are required.
