Test system and hydraulic pump device

摘要

PROBLEM TO BE SOLVED: To easily and adequately acquire information by which a tensile force applied to a test object can be specified and a displacement amount of the test object when the tensile force is applied.SOLUTION: In a test system 1, a jack device 10 includes: a piston rod 12 which moves in a predetermined direction in response to the pressure of a hydraulic oil and can apply a tensile force to a lock bottle L; and a stroke sensor 17 which receives supply of electricity and outputs displacement amount information of the piston rod 12. A hydraulic pump device 20 includes: a battery 23; a hydraulic pump 24 capable of supplying a hydraulic oil to the jack device 10; a DC-DC converter 26 and a cable 31 capable of supplying the electricity of the battery 23 to the stroke sensor 17; a pressure sensor 29 for detecting a pressure value of the supplied hydraulic oil; and a USB board 25 capable of inputting the displacement amount information from the stroke sensor 17, associating the displacement amount based on the displacement amount information and the pressure value with each other and outputting the associated displacement amount and the pressure value to the outside.SELECTED DRAWING: Figure 1
