Relationship between vacuum degree and cross-sectional area
Thread Content
Our factory drills holes quite densely when installing the belts on the filter machines. Some people say that too many holes result in a poor vacuum effect, while the manufacturer claims that theoretically, a larger inlet cross-sectional area leads to a better vacuum level. I would like to ask everyone: is there any specific relationship between these factors?
The cross-sectional area affects the pumping rate; it is necessary to check the compatibility between the parameters of the vacuum pump and the cross-sectional area of the pipes
