Maintenance knowledge of terminal blocks in pneumatic systems

Terminals are widely used in pneumatic systems, so how can we do a good job of maintenance of terminals? Shanghai Lianjie Electric makes the following suggestions:

1. Every six months, use the dial indicator to check the backlash of X, Y, Z three feed axis and B axis, and perform the necessary gap compensation again; every year, we must recheck the machine tool according to the certificate of conformity. The main precision project.

2. Use a dial indicator every six months to check the backlash status and clean the filter once a year.

3. Inspect the wear of the electrical parts of the electrical box and the operating panel every six months, the sensitivity of the limit switches, sensors, solenoid valves, and the firmness of the terminals and terminal screws.

4. After the new machine tool is installed and adjusted six months later, due to the slight sinking of the foundation mud hole during solidification, the foundation must be re-adjusted. After that, the bed level shall be checked with a 0.02/1000 level meter every year and adjusted.

The general installation environment requirements of the terminal block: The minimum ambient temperature is -5°C and the maximum ambient temperature is 40°C. A large number of studies have shown that the failure rate of the terminal rises exponentially with increasing temperature, and the service life decreases exponentially with increasing temperature. When the ambient temperature rises by 10° C., the service life of the terminal will be reduced by half.

In addition, Shanghai Jie Jie Electric reminded that to ensure that the pneumatic terminal system in the operation of the terminal is good, and the environment is also a great degree of cleanliness, and in the check whether the terminal is fastened, to ensure the correct and reliable connection of various electrical circuits, to prevent not The necessary downtime occurred.
