Blister machine vacuum pump system seal

Research on the sealing requirements of the vacuum pump system: when the vacuum pump is in the limit state, the water discharged from the first stage is very little, sometimes even no water. Therefore, a large amount of water is discharged from the first stage pump, which can be considered as a leak in the system. The usual causes of air leakage are: gaskets are not installed, installed incorrectly or damaged, bolts are not tightened, flange surfaces are damaged, welds have trachoma, and joints (pressure gauges, vacuum gauges, etc.) are not installed properly.
