**Jane Hydraulic Universal Testing Machine Maintenance Guide** Maintaining a hydraulic universal testing machine is essential to ensure its accuracy, longevity, and safe operation. Whether you're a technician or an operator, following proper maintenance procedures can prevent costly breakdowns and improve efficiency. Below are some key maintenance tips for the Jane hydraulic universal testing machine. **Machine Host Maintenance:** 1. Always apply anti-rust oil to the fixtures of the testing machine to prevent corrosion, especially in humid environments. 2. The jaws of the hydraulic universal testing machine are subject to frequent use and may wear over time. If they become too worn, it can lead to damage to the small pistons. Make sure to clean the jaws after each test and apply lubricating oil regularly. 3. Clean the sliding surfaces of the embedded steel plate and lining plate, as well as the dovetail groove surface of the lining plate. Apply a thin layer of MoS₂ (molybdenum disulfide) grease to ensure smooth movement and reduce friction. 4. Periodically check the screws on the jaws. If any are loose, tighten them immediately to maintain stability and prevent accidents. 5. Inspect the sprocket's transmission mechanism regularly. If the chain becomes loose, adjust the tensioner to restore proper function. **Oil Source Maintenance:** 1. Regularly inspect both the main unit and the oil source for signs of leakage. If any leaks are detected, replace the seal rings or gaskets promptly to avoid further damage. 2. Based on the machine’s usage and the condition of the hydraulic oil, replace the oil filter and filter elements as needed. Also, change the hydraulic oil according to the manufacturer's recommendations. 3. When the machine is not in use for an extended period, turn off the power supply. If the machine is in standby mode, set the transfer switch to the "load" position. Leaving it in the "fast retreat" position can cause the electromagnetic reversing valve to remain energized, which may shorten the device's lifespan. **Control System Maintenance:** 1. Check the rear panel of the control system periodically to ensure all connections are secure and in good contact. If any connections are loose, tighten them immediately. 2. After completing an experiment, it’s advisable to disconnect the controller from the computer if it won’t be used for a long time. This helps protect the system from potential electrical surges or software issues. 3. Ensure that all interfaces on the controller are correctly matched. Incorrectly connecting the interfaces could potentially damage the equipment or cause malfunctions. Proper maintenance not only extends the life of your hydraulic universal testing machine but also ensures accurate and reliable results. By following these guidelines, you can keep your equipment in top working condition and avoid unnecessary downtime.
