ABSTRACT:
A desurging system is placed in the fluid flow line near the output of a fluid pump to remove pressure fluctuations created in the flowing fluid by action of the fluid pump. The fluid passes through a gas-loaded, diaphragm type, fluid desurger. A gas volume control unit automatically controls the gas volume in the desurger by controlling both the gas-charging and the gas-discharging operations in response to measurements of the gas volume in the desurger and the gas flow rate into and out of the desurger. A diaphragm protection control unit is responsive to a measurement of the differential pressure across the diaphragm of the desurger to automatically bleed off the gas pressure in the desurger any time that such pressure exceeds the strength limitations of the diaphragm.
