How To Replace The Mechanical Seal Of The Nano Sand Mill?

The mechanical seal is one of the basic mechanical components with precision and complex structure. It is a key component of the nano sand mill equipment. If the sealing performance of the mechanical seal is not good, it will directly lead to the leakage of materials when the machine is grinding materials. In the daily work of the sand mill, it is necessary to pay attention to regularly check the sealing performance of the mechanical seal, and know how to replace the mechanical seal. The following editor will explain how to replace the mechanical seal of the nano sand mill:

1. Remove the barrel;

2. Remove the dispersing disc assembly and remove the screen.

3. Clean the shaft with solvent, and remove the front end cover of the barrel and the discharge cover.

4. Remove the two elastic rubber hoses and remove the discharge tray.

5. Remove the sealing ring. When removing the sealing ring, remember not to use gravity or collision.

6. Remove the gasket and the bearing protection device. After all the parts are down, they must be cleaned carefully, especially the moving ring and the static ring, to ensure that they are spotless.

7. Reassemble the mechanical seal.

8. Install the bearing protection device.

9. Put the springs into the small holes of the bearing protection device and stick them with a little grease to keep them in the correct position.

10. Install the washer and O-ring seal on the shaft, then install the moving ring, and make the washer lean against the small spring, and check whether the O-ring device is correct, and whether the pin of the bearing protection device passes through the washer and the moving ring seat. hole.

11. Install the tray and check that it is in the correct position.

12. Then connect the rubber tube.

13. Install the front end of the cylinder on the base and check whether the position of the scraper is completely in the middle position, otherwise it should be adjusted to the center.

14. Assemble the screen and the dispersion plate on the shaft.

15. Rotate the shaft by hand to keep a 0.4mm gap between the inner scraper and the outer scraper.

16. Install the cylinder and check whether the lubricating fluid is in the correct position.

In fact, in the case of long-term use of the nano sand mill, it is necessary to regularly check the sealing performance of the mechanical seal of the sand mill, and the maintenance methods for mechanical seal failure. General operators should learn and master, and they can repair themselves when problems occur. In order to avoid delaying production needs, if problems occur that are not easy to solve, they must be handled by professionals.
