The screw blade is an important part of the screw conveyor. During the use of the screw conveyor, with the passage of time, the screw blade, especially the outer side of the blade, will be ground by the material, or the friction caused by the closeness of the pipe wall during installation will make it thinner and thinner. When the screw conveyor conveys materials with high friction coefficient for a long time, it is necessary to replace the screw blades frequently. Whether it is a spare new helical blade or a replaced helical blade, maintenance work must be done. Kunwei Machinery summarizes the correct preservation methods of the following spiral blades for your reference:
1. For new spiral blades that are not in use for the time being, do not open the original packaging, and store them in a ventilated and dry place.
2. The used spiral blades should be washed with clean diesel oil to remove carbon deposits and other contaminants. After they are assembled in pairs, put them into a container containing clean engine oil. The height of the oil surface is suitable to prevent the parts from being exposed to the oil surface and in contact with the air, so as to prevent rust and not affect the repair of the spiral blades.
3. The finishing parts of the surface of the spiral blade should be coated with grease and packaged, and stored in a dry and ventilated place.
4. The blades of screw conveyors with shafts should be placed flat or vertical with longer shafts, and should not be placed obliquely to avoid deformation.
5. Do not expose or contact with harmful substances to prevent corrosion and reduce performance.
The above is an introduction to the correct preservation of the spiral blade. Knowing these is convenient for us to save the spiral blade before and after replacement, so that the parts can better play their due performance and prolong the service life of the equipment.
