Replacing disperser blades and stirring shafts may vary by device model and manufacturer. Here are the general steps:
Preparation: Make sure the disperser has been shut down and power is disconnected. Remove all relevant piping and connecting parts and clean the work area.
Removal of the blades: Depending on the design of the disperser, it is usually necessary to remove the blades. A tool such as a wrench may be required to unscrew the nuts or bolts holding the blades. Be careful not to damage the blades or adjacent parts.
Remove the stirring shaft: In some dispersers, the stirring shaft can be removed directly from the blades. Check for nuts or bolts holding the stirring shaft and unscrew it with the appropriate tools.
Install new blades and stirring shafts: Insert the new blades and stirring shafts into place. Make sure they are properly aligned and use nuts or bolts to hold them in place.
Assemble other parts: Reconnect the pipes and other related parts of the disperser. Make sure all connections are tight and reinstall gaskets, bearings, etc. as needed.
Testing and commissioning: After reinstalling the vane and stirring shaft, restart the disperser and conduct testing and commissioning. Make sure the equipment is running smoothly and check for any abnormalities or leaks.
Please note that the above steps are for general guidance only, and specific operating steps may vary by disperser model and manufacturer. Therefore, before performing any repair or replacement work, please consult the equipment's operating manual and follow the instructions provided by the manufacturer. Also, if you are not familiar with disperser repair and maintenance operations, consider consulting a professional technician or contacting the manufacturer for support and guidance.
