[PSUBS-MAILIST] regulator for compensating

[via Personal_Submersibles]

Hank,

 

The lenght should be not a problem.You can create a small overpressure by placing the second stage as low as possible. Any water or condensation will be expelled during ascending as another advantage. Flow restriction sounds ok.

Onderwerp: [PSUBS-MAILIST] regulator for compensating

 

HI All, I have been playing around with and installing a first and second stage regulator on my ROV to compensate the arm etc.  Alan has raised a very valid concern.  The pressure differential between intake and exhaust is very slight and make me think the air may not make it to the arm motors.  Alan has suggested extending the exhaust ports to create more back pressure.  I was also thinking about restricting the volume allowed to exhaust, so if it free flows the restriction will help close the exhaust valve.  

Any thoughts on the matter?

Hank
