Universal material testing machine is a high precision testing instrument, the daily maintenance of the equipment to ensure the normal operation and measurement accuracy is very important. Mainly to the main engine, oil source, control system maintenance based:
One, the main engine maintenance
1, the machine should be equipped with the fixture should be coated with anti rust oil;
2, due to the often used in the jaws of a hydraulic universal testing machine, easy to wear, oxidation skin too much, easily lead to leakage of small piston damage, so the clamp
The mouth should be cleaned regularly, and keep it clean;
3, insert plate and the lining plate is in contact with the sliding surface and lining board dovetail groove surface should be kept clean, coated with a thin layer of MoS2 (MoS2) grease on a regular basis.
Screw 4, regularly check the jaw position, if found loose, timely tightening;
5, regular inspection of the transmission of the sprocket wheel, if found loose, please re open the tension round;
Two, control system maintenance
1, check the controller regularly after the panel of the connecting line is good, if there is a loose, should be promptly tightened;
2, if there is a long time after the test without the machine, the controller and the computer shut down;
3, the controller on the interface for the one one, the wrong interface can be inserted into the device damage;
4, the plug on the interface must be shut off the controller power supply.
Three, oil source maintenance
1, the regular inspection of the host and the oil source is a place where there is oil leakage, such as the discovery of oil spills, should be promptly replaced the sealing ring or combination pad;
2, according to the use of the machine and the use of oil, regular replacement of oil filter and filter element, the replacement of hydraulic oil.
3, long time not to do the test, pay attention to turn off the host power supply. If the machine in the standby state, the switch should call the "load" file, because if switch on "rewind" file, electromagnetic reversing valve has been in power on state, affect the service life of the device.
