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


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

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

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

4. Regularly check the screws at the jaws of the jaws, if loose, tighten them in time;

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

Oil source maintenance:

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

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

3 When not testing 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 “load” 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.

Control system maintenance:

1 Regularly check whether the connection wire on the rear panel of the controller is in good contact, if it is loose, it should be tightened 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 have a one-to-one correspondence. Inserting the wrong interface may cause damage to the device.

4 The power of the controller must be turned off when plugging or unplugging the interface on the controller.

The above are some maintenance knowledge of the universal testing machine, which is for the reference of the majority of testing machine users!!
