What are the steps for inspecting the melt pump of the extruder during the turning process?

1. Before heating the extruder melt pump, manually rotate the pump shaft in both forward and reverse directions (allowing for turning from the rear of the motor) at least once. The extruder melt pump should rotate flexibly, without jamming, abnormal noise, and vibration.

2. After the extruder melt pump heats up, manually turn it in both forward and reverse directions (allowing it to be turned from the rear of the motor), and rotate the pump shaft in both directions for at least one revolution. The extruder melt gear pump should rotate flexibly, without jamming, abnormal noise, and vibration.

3. It is recommended to turn the engine separately in different temperature ranges to facilitate the detection, analysis, and handling of abnormal situations.

4. After reaching the operating temperature and before preparing for feeding, it is necessary to rotate the machine in both forward and reverse directions for at least one week. The extruder melt gear pump should rotate flexibly, without jamming, abnormal noise, and vibration.

The heating time of the extruder melt pump depends on the system, and it must wait until the pump body temperature reaches the design requirements and the insulation is sufficient before starting up. Zhengzhou Batte is a professional melt pump manufacturing enterprise, providing melt pump specifications and models ranging from 0.1CC-20000CC. Customized production can also be provided according to user needs.
