Vacuum system renovation plan, please help take a look
Thread Content
The vacuum system in my unit consists of a 200L vertical reciprocating pump. Now, the unit is to be upgraded to increase its capacity; in order to achieve a higher level of vacuum, I plan to add a 300L Roots vacuum pump in front of the reciprocating pump, along with a small water cooler behind it. I’m not sure whether this modification will allow us to reach the desired vacuum level Without precise data analysis, does anyone with experience have any advice on how much the vacuum level can be improved by making such changes? The vacuum distillation column installed in my plant is of the type used for processing base oil-grade fillers; the gas-phase load is not high. After the plant is upgraded to increase its production capacity, there might be a small amount of dissolved hydrogen, which could result in a slightly higher gas-phase load, but not by much. The current vacuum level in the plant is -0.090 MPa; I’m not sure what level it will reach after the upgrades
Without detailed data, it’s impossible to calculate; contact the design institute instead.
After the vertical vacuum pump creates a vacuum, activating the Roots pump will yield better results; ultimately, the amount of gas to be evacuated must be determined based on the requirements of the operating conditions
Agree with what was said above; I remember that when using a Roots pump for pressure increase, a pump must be installed in front of it, as the operating conditions for Roots pumps require high precision. Is the same true for vacuum pumps? It is recommended to confirm the suction pressure with the Roots vacuum pump manufacturer.
