The electronic universal testing machine is a commonly used industrial equipment and has a high frequency of use. Therefore, it should be regularly checked and maintained to ensure that problems that may cause malfunctions are detected and resolved early. The periodic inspection of the electronic universal testing machine needs to follow certain steps. Enterprises should design the steps when conducting regular inspections of electronic universal testing machines, and strictly follow these steps to operate.

Enter the sample size information of each channel, and the PLC can automatically calculate the required pressure, set the actual upper and lower pressure limits according to the pressure, open the manual pressure valve and manual pressure relief valve of the channel, and issue a running instruction for the channel At this time, the system will automatically pressurize in this, and automatically adjust the pressure, adjust the pressure within the set range, and perform a pressure resistance or burst test. The temperature of the incubator is controlled by the temperature controller. After the test temperature is set, press the temperature increase button. At this time, the circulating pump of the incubator starts to work and starts to warm up. When the set temperature is reached, the controller will automatically adjust to make the temperature Keep within ± 1 ° C.

 

Maintenance introduction of electronic universal testing machine:

The fixtures equipped with the testing machine should be coated with anti-rust oil for storage;

Because the jaws of the testing machine are often used, they are easy to wear and tear. When there are too many scales, it is easy to cause damage to the small piston and leak oil.Therefore, the jaws should be cleaned frequently to keep them clean;

Regularly check the screws in the jaw area, and if they are loose, tighten them in time;

Check the transmission of the sprocket regularly. If there is any looseness, re-tension the tension-er.

 

Maintenance of the oil source of the electronic universal testing machine:

Check the main engine and oil source regularly for any oil leakage. If any oil leakage is found, replace the seal ring or combination pad in time;

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

When not testing for a long time, pay attention to turning off the power of the host. If the test 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 "rewind" position, the electromagnetic directional valve is always energized, which will affect the service life of the device.
