The application relates to the technical field of sealing performance testing, and discloses a special
test equipment for sealing gaskets, which comprises a support frame, a
workbench fixedly connected to the top of the support frame, a sliding seat and a fixed seat arranged on the
workbench, a driving mechanism arranged at the bottom of the sliding seat, a test
assembly arranged on the sliding seat and the fixed seat, a
pressure injection mechanism arranged on the test
assembly, a controller arranged on one side of the support frame, a monitoring cabinet arranged on the side, away from the controller, of the support frame, and a
temperature control mechanism arranged at the back of the
workbench. The
temperature control mechanism with the rear feeding function releases the operation space at the front end of the equipment, facilitates the feeding and discharging of workpieces, constructs a transient linkage mechanism of
pressure monitoring,
temperature control cover retreat and camera positioning, quickly opens the cover to take a snapshot at the moment of high-temperature leakage, can accurately
record the critical failure mode before the
gasket is restored by heat shrinkage, and realizes auxiliary centering in cooperation with the bottom lifting support bracket, thereby effectively improving the testing accuracy.
