The invention relates to a shield pressure maintaining system experiment device and a using method thereof.The shield pressure maintaining system experiment device comprises a vertical storage tank, a simulation slurry bin, a main air inlet pipeline, an auxiliary air inlet pipeline, a main exhaust pipeline, an auxiliary exhaust pipeline, a to-be-tested shield pressure maintaining system and a display instrument, and the to-be-tested shield pressure maintaining system comprises a pneumatic controller, an air inlet valve and an exhaust valve; the auxiliary air inlet pipeline is connected with the main air inlet pipeline in parallel, and the auxiliary exhaust pipeline is connected to the main exhaust pipeline. Different working conditions faced by a shield pressure maintaining system during shield working can be simulated by respectively controlling on-off of a main air inlet pipeline, an auxiliary air inlet pipeline, a main exhaust pipeline and an auxiliary exhaust pipeline, and a pneumatic controller compares
