Maintenance method of universal material testing machine

The universal material testing machine is a high-precision testing instrument, and daily maintenance is of great significance to ensure the normal operation and measurement accuracy of the equipment.

Host maintenance:

1. The fixtures of the machine should be coated with anti-rust oil for storage;

2. universal material testing machine Since the jaws of the hydraulic universal testing machine are often used, they are easy to wear, and too much oxide scale can easily cause the small piston to damage and leak oil, so the jaws should be cleaned frequently and kept clean (clean after each test);

3. The sliding surface of the inlaid steel plate and the lining plate and the dovetail groove surface of the lining plate should be kept clean, and a thin layer of MoS2 (molybdenum disulfide) grease should be applied regularly;

4. Regularly check the screws at the jaws, and tighten them in time if they are found to be loose;

5. Regularly check the transmission of the sprocket. If there is any looseness, please re-tension the tensioning wheel;

1. Regularly check whether there is oil leakage at the main engine and oil source. If oil leakage is found, replace the sealing ring or combination gasket in time;

2. According to the use of the machine and the life of the oil, replace the suction filter and filter element regularly, and replace the hydraulic oil.

3. When not doing the test for a long time, pay attention to turn off the power of the host. If the machine is in the standby state, the transfer switch should be set to the "loading" position, because if the transfer switch is set to the "fast reverse" position, the solenoid valve is always energized, which will affect the service life of the device.
