<p><P>PROBLEM TO BE SOLVED: To provide a slurry pump and a slurry transportation device capable of more surely transporting slurry. <P>SOLUTION: This slurry pump includes: a shaft body reciprocating in an axis direction; a pressure feed chamber which becomes a pressure reduction state when the shaft body moves in a separating direction and becomes a pressurizing state when the shaft body moves in an approaching direction; a supply port which is provided on an upper side of the pressure feed chamber and to which slurry is supplied; a discharge port which is provided on a lower side of the pressure feed chamber to discharge slurry; a supply port valve which is elastically energized to close the supply port and opens against elastic force so that slurry is supplied to the inside of the pressure feed chamber through the supply port when the pressure feed chamber becomes the pressure reduction state; and a discharge port valve which is elastically energized to close the discharge port and opens against elastic force so that slurry in the pressure feed chamber is discharged through the discharge port when the pressure feed chamber becomes the pressurizing state. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
