APPARATUS AND METHOD FOR PUMPING A CRYOGENIC FLUID FROM A STORAGE VESSEL AND DIAGNOSING CRYOGENIC PUMP PERFORMANCE |
摘要 |
<p>An apparatus and method are provided for pumping a cryogenic fluid from a storage vessel. The cryogenic fluid is pumped from the storage vessel to a heat exchanger and then to a delivery conduit. A pressure sensor measures fluid pressure in the delivery conduit. An electronic controller is programmed to monitor a signal from the pressure sensor, process the signal to determine from the measured process fluid pressure when cryogenic pump performance is degraded, and to send a signal to an operator of the apparatus indicating when the electronic controller determines that cryogenic pump performance has degraded below a predetermined threshold volumetric efficiency.</p> |
