Is an inlet control valve installed at the inlet of the CO2 blower?
Thread Content
In order to achieve more thorough CO2 flashing in section IV of the low-temperature methanol wash CO2 flasher, our company reduces the pressure in section IV to a vacuum level for flashing. The method used is to create a vacuum with a CO2 blower. I would like to ask the experts: is it necessary to install an inlet control valve on this CO2 blower in order to reduce its starting torque? The CO2 blower is driven by an asynchronous motor.
The fan startup inlet is closed, and the outlet is open. The inlet is closed to prevent the fan from starting under load, while the outlet is opened to avoid pressure buildup inside the wind casing during fan startup, which could lead to vortices and vibrations
There is no need to install a control valve; only a manual valve is required.
Agree with what was said on the second floor. Ours is self-regulating, but a manual valve would work as well
