Operational issues in vacuum distillation towers

There are slight fluctuations in the liquid level of the buffer tank in the pressure reduction system’s water ring vacuum pump; pressure also fluctuates, and the vacuum level is not stable. Additionally, the sound emitted by the booster at the top of the pressure reduction tower is abnormal. Currently, the steam pressure from the pipeline network is unstable; is this related?
Generally, water ring vacuum pumps also have good stability. The ones used by our company produce much less noise compared to steam jet pumps; it’s worth checking whether there is something wrong with the machines themselves
The instability of steam pressure plays a significant role
It’s related to steam pressure, as well as faults in the equipment itself – all of these factors play a role
Fluctuations in steam pressure will inevitably lead to fluctuations in the pumping efficiency of the vacuum pump; it is recommended to install a steam pressure control valve, as well as a condensate drain at the valve assembly
In the pressure reduction system, there are slight fluctuations in the liquid level of the water ring vacuum pump’s buffer tank; this leads to pressure fluctuations as well, and the vacuum level is not stable. Additionally, the sound emitted by the booster at the top of the pressure reduction tower is abnormal. It is mainly caused by abnormal operation of the booster at the top of the pressure reduction tower. To resolve the issue, it is necessary to eliminate the abnormal noise produced by the booster, that is, to stop surging in the booster; ideally, the steam pressure should also be increased appropriately.
Unstable steam pressure or steam containing water has a significant impact on the proper operation of the vacuum pump
