Hydraulic pressure from PAS to bomb

[orsum]

Anybody have a clue what hydraulic pressure is applied to the bomb from the PAS while charging and what is the Nitrogen charge pressure of the bomb when empty of hydraulic fluid.

I have seen figures of the nitrogen pressure from 70 to 90bar charged and at 30bar when it needs to have the nitrogen charged.

I have a friend in the hydraulic game who said they can check mine and if there is a problem then they can overhaul it, it including replacing the bladder with the latest bladder material.

All he is asking for is the nitrogen charge pressure and hydraulic working pressure.

He also said he should be able to supply an equivalent replacement if necessary.

New accumulator charge pressure 73-77 bar at 20c
Min accumulator charge pressure 30 bar at 20c

Minimum operating pressure 140 bar at idle
Pump output minimum flow 0.25L/min at idle

Any idea about the max pressure and flow?

Minimum operating pressure 140 bar at idle
Pump output minimum flow 0.25L/min at idle

Thanks

Sorry I can't find any data on that.
Since these are quoted figures at idle speed I would imagine those are the required operating specifications.

Thanks for trying.

Does not feel right not knowing and going into a repair.

It must be available on the internet

I am sure I could measure mine but that's still taking a chance, how do I know mine is right.

Workshop manual states operating pressure of approx 140bar
Low pressure switch triggers at 127 - 87 bar
