What does memory reset mean before the FCC main fan is started?
Thread Content
As the title suggests: What is recorded in the memory? How is reset performed?
The memory must be the accumulator, right? The accumulators of high-temperature butterfly valves and high-temperature gate valves are reset to ensure that these special valves can still complete one cycle of opening and closing even when the power oil pump fails. Ensure the safety of the device. It’s just like opening the anti-surge valve before starting the fan.
Reply to 3# Desert Off-road Fly: Does the main fan have an accumulator?
Reply to 4# 328104062: I can only say that they are available at gas stations. For the axial flow main fans with adjustable vanes, there are hydraulic and electric systems for adjusting the vanes’ angle. There are no electric ones. There are simply no centrifugal ones.
Reply to 4# 328104062: I was wrong. What was mentioned was memory reset; I mistook it for an accumulator. Sorry.
Is no one coming to talk? ? ? ? ? ?
1. The centrifugal main fan units here also have an accumulator system in their oil circuit system. 2. The memory referred to by the poster is likely a startup confirmation circuit system in the unit control system; the startup conditions are met only after this confirmation (that is, after reset), allowing the unit to be started.

Let’s go back to this now. The so-called pre-start reset is simply a check to see whether the start conditions are met. For example, whether the anti-surge valve is open, whether the oil pressure is sufficient, whether the high-temperature gate valves and butterfly valves are closed, etc. If any of these conditions are not met, it is not possible to start the main fan without addressing those issues first. He is in a conditional relationship……
What was said upstairs is correct; it should be the software chain condition
