Are there any standards for daily maintenance and inspection of the accumulators in the aircraft’s lubrication system?
Thread Content
I heard it needs to be checked once a month? Which items need to be checked? Also, how should inspections be carried out during major overhauls, and what are the requirements for the replacement cycle of the casing?
What’s the point of having inspections that are too frequent? Isn’t it one in use and one as a backup?
Large-scale units have only one accumulator, and the usual inspection items include checking whether it can maintain pressure, determining whether the air bag is damaged, and detecting oil leaks. We all check during maintenance and purge with nitrogen in a timely manner. Airbags generally don’t break and don’t need to be replaced.
It’s not one; in the ethylene tri-unit here, the cracking gas compressor alone has 3 accumulators for its lubricating oil system, 1 for its control oil system, and another 6 for its seal oil system.
