Regarding the speed of the turbine expander
Thread Content
I need help – I’d like to ask the more experienced colleagues why, when the load on the fan filter of the expander increases, the speed of the expander starts to rise ?
Do you mean an oil mist fan by fan?
Do you mean an oil mist fan by fan? No, I’m referring to the air intake fan – that is, the fan whose filter element needs to be replaced when the speed of the expander reaches a certain level.
Reply to 1# Da3076: When the fan filter of the expander has a high resistance, it’s equivalent to reducing the opening degree of the fan’s butterfly valve. So the speed of the expander increases
Reply to 1# Da3076: The fan exerts a braking torque on the expander; as the fan resistance increases, the air flow decreases. This means that the braking torque on the expander is reduced, so the speed of the expander increases. It’s like brakes – when they can no longer function properly
The machine of the expander serves to provide braking and to absorb the energy generated by the expander. When starting the expander, the fan is turned up to full speed in order to prevent excessive rapid acceleration that could lead to runaway operation; once the expander is running, the fan is gradually turned down to increase the speed, which reduces the braking effect and thus boosts the speed. When the filter becomes clogged, it is as if the flow rate of air through the fan is reduced, resulting in an increase in speed
The fan resistance is too high, resulting in a decrease in driving torque; under the original conditions, the speed of the expander increases.
Wind mechanism braking wastes energy; it is recommended to add another generator for power generation.
The expander’s mechanism serves to provide braking and to dissipate the energy generated by the expander. When starting the expander, it is necessary to operate the fan at full capacity in order to prevent excessive speed during startup. Once the expander is running...

May I ask where exactly the expander fan is located? Study*.
The power for the expander comes from the high-pressure gas downstream of the booster; the amount of gas and the pressure level affect the speed of the unit； If the inlet filter of the booster pump becomes clogged, with no change in the check valve, will the air intake volume of the booster pump decrease? Then the air intake volume of the expander also decreases relatively. Since the amount of gas expanding decreases, shouldn’t the speed of the expander drop as well? Solve~~~~~~~~~~~~~~~~~
