Follow plate, pumping and pumping equipment and the method of storage solution

摘要

PROBLEM TO BE SOLVED: To provide a follow plate capable of surely making a storage liquid flow out of an outflow port of a pump at a predetermined flow rate, by surely exhausting air on the under surface side of the follow plate in outside air, when contacting the follow plate with a liquid surface of the storage liquid stored in a vessel.;SOLUTION: This follow plate 12 is provided for making the storage liquid 3 flow out by pumping up the storage liquid 3 by the pump, by installing a suction port part of the pump in an installation hole 47 formed in the follow plate 12 arranged on this liquid surface, by arranging the follow plate 12 on the liquid surface of the storage liquid 3 stored in the vessel 2. The follow plate 12 is sealed between its outer peripheral part 12a and an inner peripheral surface 2a of the vessel 2 in a state of being inserted into the vessel 2. The installation hole 47 is constituted so that air existing between the liquid surface and an under surface 12b of the follow plate 12 arranged on the liquid surface, can be exhausted in the outside air.;COPYRIGHT: (C)2008,JPO&INPIT
