Questions regarding vacuum pump units
Thread Content
At an intake air temperature of 220 degrees, can vacuum pumping be done directly using a vacuum pump unit? Without performing preliminary cooling.
Same question, but it seems theoretically unfeasible; the temperature of the air compressed by the vacuum unit is already high, and cooling is necessary.
Has the vacuum level reached -0.94 MPa?
Right. Grade 3 vacuum. Inlet air temperature: 200 degrees
Using a water ring vacuum pump as a pre-stage pump at this temperature is certainly inappropriate. The units produced in this way cannot be used
Do you manufacture water ring vacuum pumps? Thank you
A solution using a screw vacuum pump paired with an inverter-driven motor can be adopted; for the vacuum system, a single LG300 screw vacuum pump is sufficient. Using a rotary vane pump to operate at such low pressures is not very appropriate.
A water distribution ring with over 200 temperature settings will be a nightmare to use; a dry pump is the proper solution.
The water ring definitely can’t be used. I wouldn’t dare to say such high temperatures for dry testing either.
