<p><P>PROBLEM TO BE SOLVED: To provide a device for attaching and detaching a pump and a pump device which employ structure for vertically moving the pump smoothly, and further suppress a positional deviation in a joint part between the pump and a delivery pipe to the minimum, thereby suppressing the leakage on the joint part. <P>SOLUTION: The device for attaching and detaching pump includes: a connection straight pipe 60 connected to a delivery port and a delivery pipe of a submerged pump; a base part 71 which is disposed on the connection straight pipe 60, is arranged oppositely to a guide pipe 30 and has a tapered part 72; an arm part 75 which is disposed along an outer circumferential part of the guide pipe 30 from the base part 71 and is engaged with the guide pipe 30 together with the base part 71; and a projection part 76 which is disposed on a position, opposite to the guide pipe 30, of the arm part 75 and is disposed on the position respectively vertical to the axial direction of the guide pipe 30 and the axial direction of the connection straight pipe 60 along the vertical direction of the guide pipe 30 while making the distance for the guide pipe 30 constant. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
