<P>PROBLEM TO BE SOLVED: To obtain a DC pump inspection device easily inspecting performance of a DC pump in an incorporated state in a product while observing constraint concerning drive of the pump. <P>SOLUTION: The pump inspection device comprises a control section 1 for driving the DC pump within a drive condition range of the pump limited when the DC pump 20 is driven without pouring water in a water circuit 30 and for applying an indicator voltage to the DC pump 20 while increasing the indictor voltage for driving the DC pump 20 and judging based on a pump rotation rate of the DC pump 20 whether the DC pump 20 is abnormal or normal. The control section 1 applies the indicator voltage to the DC pump 20 so that the DC pump 20 is driven within a limited range concerning the pump rotation rate included in the drive condition range, and judges that the DC pump 20 is abnormal due to wire connection defect or a defective product when the pump rotation rate equal to or higher than a predetermined value cannot be detected within a drive limit time. <P>COPYRIGHT: (C)2009,JPO&INPIT |
