Can an old Roots vacuum pump be used as a Roots blower? Why? Thank you all!
Theoretically, I think it’s possible; it’s just that the inlet pressures are different. When reusing existing equipment, you need to consider whether the operating conditions can meet the requirements of the old Roots pump, especially the operating temperature.
When used as a fan, it depends on what your outlet air pressure is and the temperature of the inlet air If the wind pressure exceeds the compression ratio during vacuum pumping and the inlet temperature is higher than before, the fan temperature will rise compared to normal levels; in severe cases, this can damage the impeller.
No, because the design is different: it presents a low load when used as a load on a vacuum pump, but a high load when used with a Roots blower!
