working principle:

The working principle of vacuum suction: A certain negative pressure is formed in the hopper cavity to suck the material into the hopper. The feeding equipment forms an airflow under vacuum, and the material conveyed under this airflow is instantly transported to another container through the suction tube. Due to the fact that the material is always in a vacuum state during the conveying process, even if there is a leak in the conveying pipeline, the material will not leak into the surrounding environment.

The principle of the fully automatic microcomputer vacuum suction machine: When there is a shortage of material in the hopper, the contact switch sends a signal to the microcomputer of the suction machine, and the microcomputer sends a signal to start the motor for vacuum suction. When the closed system reaches a certain degree of vacuum, it starts to suction the material. After suction, the material is discharged into the hopper. When the material reaches a certain level, the suction machine stops, and when there is not enough material, it can be conveyed again.
