firstly, a plurality of electroceramic samples to be detected are put into a pressure testing tank 21, industrial anhydrous alcohol and a proper amount of fuchsin are poured into the pressure testing tank 21 and then sealed, an advancing button on an electric cabinet 2 is pressed, a motor 4 is started and drives an oil pump 5 to pump hydraulic oil, the hydraulic oil enters an oil cavity 17 of a pressure boosting cylinder 16 through a reversing valve 13 and a pressure retaining valve 14, a piston moves forwards and compresses fuchsin solution, and the upper pressure in the pressure testing tank 21 is increased. When the pressure upper limit value set by the magenta pressure gauge 20 is reached, the PLC detects the pressure upper limit signal of the magenta pressure gauge 20, so that the motor 4 stops working and the magenta cavity 19 enters a pressure maintaining state. When the pressure value is lower than the lower pressure limit value set by the magenta pressure gauge 20 due to pressure leakage, the PLC controller detects the lower pressure limit signal of the magenta pressure gauge 20 and starts the pressure compensation program, so that the motor 4 works until the pressure reaches the upper pressure limit value set by the magenta pressure gauge 20 again, and the magenta chamber 19 enters the pressure maintaining state again.
Under the detection and control of the PLC, the operations are circulated in a reciprocating mode until the pressure maintaining time reaches a set time or an electric control upper retreating button is pressed, the motor 4 is started and drives the oil pump 5 to extract hydraulic oil, the hydraulic oil enters the oil cavity 17 of the pressure boosting cylinder 16 through the reversing valve 13 and the pressure maintaining valve 14, after a piston in the magenta cavity 19 is retreated in place, the pressure relay 15 sends a signal to the PLC, and the PLC enables the motor 4 to stop working. When the pressure value of the fuchsin pressure gauge 20 is zero, the pressure testing tank 21 is opened to take out the electroceramic sample to be tested so as to check the test result.
Because the pressure test tank 21 is filled with the fuchsin solution formed by the anhydrous alcohol and the industrial fuchsin, the fuchsin solution enters the interior of the electroceramic sample to be tested along cracks if cracks or air holes exist in the electroceramic sample to be tested under the continuous high-pressure condition, and the defect of the sample can be obviously seen after the electroceramic sample to be tested is washed by clear water after the test is finished. And if cracks exist on the surface and inside of the electric porcelain sample to be detected, red grains can be displayed, and the electric porcelain sample to be detected is an unqualified product.
