Liquid circulation type test apparatus and liquid circulation type test method

摘要

Problem to be solved: to adjust the liquid pressure applied to the test specimen in a simpler configuration in the liquid circulating test apparatus.Liquid circulation type test apparatus 10A main passage 12a provided with a pump 14A test flow path 12b which is capable of connecting the test body w and theA bypass passage 12C branched from the test flow passage 12b is provided.The circulating passage 12 is configured to circulate the fluid in fluid by the pressurizing force by the pumpA pressure change unit 20 for changing the pressure of the fluid in the test flow passage 12b by changing the opening degree of the bypass passage 12C andA storage section 24a for storing opening degree information about the change in the degree of opening of the bypass passage 12C when the pressure of the fluid flowing through the specimen flow path 12b is changed by the pressure changing section 20 andA control section 24B for controlling the pressure changing section 20 based on the opening degree information stored in the storage section 24a andIs provided.Diagram
