Pressure issues in coal tar deep processing towers
Thread Content
The pressure at the pump head remains relatively stable, but the pressure in the vacuum buffer tank fluctuates significantly, and these fluctuations are quite regular, following a wave-like pattern
Centrifugal pumps are constant-pressure pumps; their head is generally stable. Instability in the system is usually caused by liquid accumulation in the pipes or within the system (possibly at the inlet and outlet of the vacuum tank)
Maintain stable negative pressure in the tower, with a focus on the operation of the vacuum pump
