      Safe usage method of screw pump

      1、 Shutdown of screw pump

      When the screw pump is stopped, the discharge stop valve should be closed first, and the suction stop valve should be closed after the pump is completely stopped.

      Screw pumps are prone to bending due to their long working screw length and poor rigidity, resulting in abnormal operation. The connection of the shaft system must be well aligned; It is best to perform centering work after installation and positioning to avoid deformation caused by pipeline entanglement; When connecting pipelines, they should be independently fixed to minimize interference with the pump. In addition, it is best to use a hanging and fixing method for spare screws during storage to avoid deformation caused by uneven placement.

      The function of thread protectors

      Thread protectors can be used as caps and bushings to protect and seal threads during loading, unloading, transportation, and storage. In addition to being able to perform professional sheath installation, it can also be used as a repair component. During the trial period, people can experience its superior stability and repair ability. So the use of thread protectors plays a particularly important role in the entire mechanical component.

      Troubleshooting Mud Pump

      Water pump vibration
      ★ Reason: The pump shaft is not concentric with the diesel engine (or motor), the impeller is unbalanced, and the bearings are damaged;
      ★ Solution: Adjust the concentricity, conduct balance testing on the impeller, and replace the bearings.
