Screw conveyor is a kind of machinery that uses motor to drive screw rotation and push materials to achieve the purpose of conveying. It can be transported horizontally, obliquely or vertically. It has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance and closed transportation.

   Screw conveyor Each hanging bearing shall reliably lift the connecting shaft, and the screw shall not be stuck or bent. During installation, the number of gaskets for hanging bearing must be adjusted so that there is no gap between the split surfaces of the bearing, and there is an appropriate radial gap between the bearing and the connecting shaft.

When the diameter of the end face of the spiral pipe is less than or equal to 500mm, the distance between the two ends of the spiral shaft should be greater than 400mm (d).

In order to adjust the accumulated error of the length between the casing and the screw, it is allowed to add braided asbestos tape between the flanges of each casing during installation. The visual sealing requirements between the casing and the cover decide whether to add waterproof canvas or not.

When the difference between the central height of the low-speed shaft of the driving device reducer and that of the screw machine is too large, the height of the driving device can be adjusted by using the gasket.

During the no-load test run, if oil leakage is found in the bearing, the bearing shall be removed and the tightness of the spring in the sealing ring shall be adjusted until there is no oil leakage.

During the no-load test run, if the temperature rise of the hanging bearing is too high (the temperature rise of each bearing shall not exceed 20 ℃ during the no-load test run, and the temperature rise of each bearing shall not exceed 30 ℃) during the load test run, it indicates that the position of the hanging bearing is not properly installed, resulting in the jamming of the connecting shaft. The fastening bolt shall be loosened to adjust the position of the hanging bearing.
