The gas medium contains wood tar, resulting in a relatively low level of cleanliness; what type of vacuum pump is recommended?
It depends on the level of vacuum you need; a Roots pump is recommended as it makes it easy to clean the rotor and the chamber
Well, a Roots pump was also chosen for the equipment. The vacuum requirement isn’t high – slight negative pressure is sufficient. However, it still needs to be switched and cleaned frequently, as the clearance between the impellers is small, making it very easy for oil to accumulate there
What organic solvents can be used to dissolve the wooden tar in the rotor chamber? It’s necessary to clean it regularly
Xylene is a good choice, and it offers good value for money
Well, that’s true; for now, the only option is to reduce the amount of wood tar and extend the operating time
