Hydraulic oil cylinder sealing performance test equipment

The invention discloses hydraulic oil cylinder sealing performance test equipment which comprises a test box and an equipment table, and the equipment table is embedded in the test box. The feeding assembly is arranged in the testing box and comprises an auxiliary table, a liquid supply plate, a rotating table, a supporting table, a lifting table and a mounting air cylinder, the rotating table is embedded in the center of the outer wall of the auxiliary table, the liquid supply plate is embedded in the two sides of the outer wall of the auxiliary table, and the rotating table and the supporting table are fixedly arranged on one side of the outer wall of the rotating table. By means of the feeding assembly, a stable large-mass hydraulic oil cylinder can be subjected to a stable feeding simulation test, the situation that the preparation and feeding time of equipment simulation is prolonged due to complex installation and positioning problems is avoided, the hydraulic oil cylinder can be wrapped and protected t
