Have a question concerning a high pressure thermal unit used to cool the double seals on a shear pump.
Pin = 55psi
Pout = 90 psi
(uncharacteristic, but true (usually, a pressure drop
across the housing, but there is back pressure being applied to the outlet side for other reasons).
Need to pressurize the cooling unit to 115 psi to ensure
the oil will flow into the product and not vice versa if the seals fail.
What is the effect on the cooling loop (barrier fluid)
pressurizing the cooling vessel to 115psi?
Will it still 'syphon'(loop)as effectively as an unpressurized vessel?
Principles?
Thanks 4 the help.

RE: Fluid Mechanics
First of all I am not very much clear about your system. Actually barrier fluid works on the principle of thermo syphoning. We have some systems and the requirement is same that of you. The barrier fluid system is supplied along with a hand lever by operating which you can increase the pressure of the fluid.
But maintaining low pressure in the inlet and high pressure in the outlet line of the mechanical opposes the very rule of the nature as generally flow takes place from high pressure to low presure.
