Cement pipe making machinery is a type of mechanical equipment used to manufacture cement pipes. These machines can generally be divided into two types: roller-type and centrifugal-type. They are mainly used to produce concrete and reinforced concrete pipes with lengths of 2-5m and inner diameters of 300-2500mm. Pipe joints include plain end, tongue and groove, and socket end. The machines are characterized by simple operation and high strength. However, due to improper operation or prolonged use, some abnormal malfunctions may inevitably occur.

When encountering malfunctions in cement pipe making machinery, the following methods can be used to resolve them:

1. Before starting the machine, check the integrity of all components and systems.

2. During use, ensure that no cement slurry adheres to the surrounding area of moving parts and perform necessary cleaning.

3. Regularly lubricate all rotating parts to ensure smooth operation.

4. Adjust the distance between the upper and lower pulleys to ensure the main motor transmits power normally, achieving the forming speed of the roller mill and ensuring the cement pipe's density meets standard requirements.

5. After a period of use, localized wear will inevitably occur at the contact points between the roller shaft and the mold retaining ring. In this case, the worn areas must be repaired with 507 welding rods to the required dimensions before reuse.

6. Proper operation and regular maintenance are essential to ensure the normal operation of the roller mill unit.
