What should be the nitrogen charging pressure of the P53B accumulator?
Thread Content
These are the parameters of the accumulator. I want to charge the accumulator now. How much should it be charged to?
53B system pressure × 0.85~ 0.9
Then look at the sign, why is the work pressure so high?
These are two concepts. The precharge pressure on the nameplate is the pressure at which the accumulator leaves the factory. What you want to ask about is the flushing pressure calculated based on the seal chamber pressure. There is no contradiction between the two.
Generally it is 0.6~0.7 (working pressure)
The nitrogen filling is 4.0bar, and then the white oil filling is generally 0.3-0.5MPa higher than the pressure inside the pump, or higher.
We calculated it like this: Inflation pressure = (0.85～0.9) * seal chamber pressure
0.85~0.9 times seal chamber pressure
