Failure Modes of a Hydraulic Pressure Compensator?

Failure Modes of a Hydraulic Pressure Compensator?

Failure Modes of a Hydraulic Pressure Compensator?

(OP)
I'm planning to use an off the shelf pressure compensator (from Sub-Atlantic, Tecnadyne or similar) to bring the pressure in an oil filled cavity 0.5 bar higher than the seawater pressure on the other side of a seal.

Can anyone advise of the likely failure modes of such a spring based pressure compensator?

A mere half a bar differential may not be enough to energize some types of seal.

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
