It will cause reverse interference, and the sealed pressure-bearing temporary storage tank will directly disrupt the steady vacuum state of the evaporator.

Pressure transmission via interconnected liquid level materials

The sealed tank builds up internal pressure, which flows backward into the evaporation chamber through the discharge return pipeline, counteracting the negative pressure of the system and leading to an involuntary drop and deviation of vacuum degree.

Temperature variations trigger expansion and contraction of air pressure inside the tank

The waste liquid contracts when cooled and expands when heated. Repeated fluctuations of air pressure in the confined space continuously exert disturbance pressure on the evaporator, resulting in frequent vacuum fluctuations.

Accumulated precipitated gas elevates tank internal pressure

Volatile substances and dissolved gas in the waste liquid separate out gradually. With no pressure relief passage in the sealed tank, internal pressure rises steadily and pushes backward to break the negative pressure balance.

Instant pressure difference impact during discharging

When the evaporator discharges materials, pressurized medium inside the tank surges in rapidly. The instantaneous pressure difference impacts the gas phase space, causing sharp vacuum drop and instability.

Pipeline air block hinders pressure buffering

Liquid and gas accumulation in connecting pipelines forms an air seal, leading to delayed and uneven pressure transmission and further aggravating vacuum jitter and imbalance.
