<p><P>PROBLEM TO BE SOLVED: To provide a pump device for reliably separating liquid from gas even when many bubbles are entrained. <P>SOLUTION: The pump device has an entrained amount detection device 21 for detecting the amount of a fluid containing many bubbles separated by a gas-liquid separation mechanism 7, and the entrained amount detection device 21 has an ejector 22 which passes the separated fluid and a pressure sensor 23 which is operated by a negative pressure generated in a mixing chamber 26 of the ejector 22. The pressure sensor 23 opens fuel oil discharge piping 4 by turning ON a proximity switch 38 when the negative pressure value exceeds a predetermined value. A turn-stop tool 52 is attached to a nozzle 25 of the ejector 22 to suppress the flow of the separated flow in a turning direction. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
