Common problems in compressors
Thread Content
In a compressor system, why does refilling the oil tank often cause the standby pump to start?
This problem is not common; to find an answer, one first needs to know the specific circumstances and the control method of the oil system, etc.! Don’t make us guess! :lol Last edited by gql on 2009-4-13 18:37 ]
Is it the unstable oil pressure at this time, along with low oil pressure, that causes the auxiliary oil pump to start?
When you accelerate, the oil temperature should change from its original value, and the oil pressure will also change; as a result, your auxiliary oil pump will start up.
It won’t be that obvious; it’s probably a problem with the instrument, maybe there’s an issue with the interconnection mechanism.
Refueling disturbs the impurities at the bottom of the tank, causing the filter screen at the pump inlet to become clogged and the oil pressure to drop, which in turn triggers the standby pump to start.
I remember that large aircraft engines all have a low fuel level alarm. Agree with the view from floor 5.
What was said upstairs is correct – when refueling, impurities that are at the bottom of the fuel tank get stirred up, which blocks the filter and causes the backup pump to start operating. It is recommended to use a fuel filter when refueling.
