How to maintain screw hoist

1. The screw hoist shall be started without load, that is, when there is no material in the casing. After the initiation, the material can be fed to the screw hoist.

2. During the initial feeding of the screw hoist, the feeding speed should be gradually increased until the additional transport capacity is reached, and the feeding should be uniform, otherwise the material accumulation and overload of the driving equipment will affect the normal service life of the screw hoist.

3. In order to ensure that the screw hoist has no load, the feeding of the screw hoist should be stopped before shutdown until the materials in the casing are in good condition

4. The material shall not be mixed with hard bulk material, so as to avoid screw jam and damage of screw hoist.

5. In operation, we often check the condition of various parts of the screw hoist, and pay attention to whether the screws of the fastening parts are loose. If we find that the parts are loose, we should immediately re tighten them.

6. Special attention should be paid to whether the screws between the connecting shafts of the spiral tube can be loosened, dropped or cut. If such phenomenon is found, the machine should be shut down immediately and corrected.

7. When the machine is working, take down the cover of the screw hoist to avoid trouble;

8. When abnormal phenomena are found in the operation of screw hoist, they should be checked and eliminated, and forced operation is not allowed;

9. The running parts of screw hoist should be lubricated frequently.
