Abstract:
1. An apparatus for loading test and experiment of liquid nitrogen pump equipments, comprising: a liquid nitrogen tank comprising an outlet pipeline and a tested liquid nitrogen pump equipment, wherein said liquid nitrogen pump equipment is arranged on the outlet pipeline of the liquid nitrogen tank and pumps liquid nitrogen at the low pressure and low temperature stored in the liquid nitrogen tank and converts it into gaseous nitrogen at normal temperature and high pressure, a hydraulic damping apparatus unit comprising a water tank comprising an outlet pipeline, pump set equipment, and a manifold system which are connected in sequence, wherein said manifold system mixes the gaseous nitrogen at normal temperature and high pressure from the liquid nitrogen pump equipment with high pressure water from the pump set equipment to form a high pressure liquid-gas mixture; and a pressure adjusting unit arranged downstream from the hydraulic damping apparatus unit, which pressurizes the water discharged from the hydraulic damping apparatus unit by adjusting the flow rate of the high pressure liquid-gas mixture.
