Equipment for sealing-performance test

An equipment for sealing-performance test, comprising a housing, a fixed mechanism and a detection part, wherein

• the housing is configured to accommodate the fixed mechanism, and an abutting part is formed in the housing, and the abutting part is configured to abut against an outer side of a sealing ring;
• the fixed mechanism comprises a central rod, a plurality of fixed blocks and a driving assembly, and the central rod extends along a direction parallel to an axial direction of the central rod, and the plurality of fixed blocks are evenly disposed along a circumferential direction of the central rod;
• the driving assembly is configured to drive the plurality of fixed blocks to move along a radial direction of the central rod, so as to make each of the fixed blocks abut against an inner side of the sealing ring;
• and
• when the abutting part abuts against the outer side of the sealing ring and all of the plurality of fixed blocks abut against the inner side of the sealing ring, a test cavity and a detection cavity are formed in the housing, the test cavity and the detection cavity are disposed along the direction parallel to the axial direction of the central rod, the sealing ring is located between the test cavity and the detection cavity so as to separate the test cavity from the detection cavity, the test cavity is filled with a test fluid, and the detection part is configured to detect the test fluid in the detection cavity.
