This equipment uses the upper cavity to press on the bottom plate to form a closed cavity (the time can be set) without opening the cavity and at the same time the secondary air is drawn out to form -70KPa and stop for a period of time (the time can be set) at the same The action of vacuuming for the third time reaches the negative pressure state of -95KPa to remove the air in the cell; the second trapezoidal vacuuming method is to prevent a large amount of electrolyte from being pumped out, and at the same time, it can completely penetrate the electrolyte.

Technical Parameter:

1. Length: (80-200 with tabs), width: (50-150 with air bag),
2. Dimensions L x W x H≈550x440x750mm (maximum height after opening the cavity)
3. Cycle times: 0-3 times can be set
4. Pumping time: 0-60min can be set
5. Standing time: 0.1-99S can be set
6. Opening stroke: 250mm
7. Vacuum tube inner diameter: 25mm, vacuum: 63³/H (63 cubic meters/H)
8. The vacuum degree of the static box: ≤0.095Mpa (the vacuum is kept for 1 minute to ensure ≤0.090Mpa)
