Abstract

The invention discloses a fluid slip ring, relates to the technical field of slip rings and aims at solving the problem that in the prior art, in the severe sea condition, a high-temperature and high-pressure large-caliber fluid slip ring is poor in running reliability. The temperature of conveyed fluid of an inner runner of the fluid slip ring is 200 DEG C, the pressure is 11 Mpa, and the drift diameter is 250 mm; and the temperature of fluid of an outer runner is 70 DEG C, the pressure is 11 Mpa, and the drift diameter is 408 mm. The fluid slip ring receives fresh water conveyed by a user, and the fresh air is heated to 200 DEG C through an oversea nuclear power platform and conveyed to the user. The existing fluid conveying slip ring cannot reach the high-temperature and high-pressure conveying capability. According to the fluid slip ring, a coaxial inserting type structure is adopted according to the large-flow high-temperature and high-pressure fluid needed by the user, the multi-runner high-temperature and high-pressure rotation sealing is achieved, and the requirement for preventing washout of gas-phase media and liquid-phase media is met; and it is guaranteed that in the severe sea condition, the fluid slip ring runs safely and reliably. The temperature, pressure and flow parameter level of fluid conveying media can be improved to a new level.

Description

technical field [0001] The invention relates to the technical field of slip rings, in particular to a fluid slip ring. Background technique [0002] Marine nuclear power high-temperature, high-pressure and large-diameter fluid slip rings are mainly used to provide medium that meets certain pressure, temperature and flow requirements to target users, and its users are mainly heavy oil production. The viscosity of heavy oil is very sensitive to temperature. As long as the temperature rises by 8-10°C, its viscosity will decrease by one time. The rate can reach the level of 40%-60%. The parameters of pressure and injection speed required for thermal recovery are also very demanding. Researching a high-temperature, high-pressure and large-diameter fluid slip ring is the key to effective development of heavy oil. [0003] At present, the multi-channel fluid slip rings used in offshore single-point mooring are basically low-temperature and low-pressure fluid slip rings, large-dia...
