The outlet temperature of the Roots blower is much higher than usual
Thread Content
I have a Roots blower used to pump gas at around 100 degrees Celsius. Today, I noticed that the outlet temperature was higher than usual, and smoke was coming from the outlet pipeline. I’m not sure what could be causing this increase in temperature; such issues haven’t occurred during normal operation. Please share your thoughts; thanks, bonus points for help!
Was it someone who turned the valve down, causing the fan to operate under load and resulting in gas compression and heat release?
Will closing the inlet or the outlet cause a load on the fan?
Regarding the outlet, I’m not sure if there is a safety valve on the fan; normally, in case of overpressure, the safety valve will release pressure. I’m not in the wind turbine industry either. Rotary vane blowers belong to positive displacement blowers. The pressure increases when the outlet is narrowed.
Is there a problem with the cooling water jacket of the Roots blower – is the cooling water not flowing properly or is its flow rate too low?
Is the outlet a one-way valve, or is there an obstruction in the outlet pipeline, which prevents the load from being sent out and causes heat generation due to self-rotation?
