Problems solved by technology
Although there is a high-power water-filled underwater motor, its structural principle determines that its working water depth is generally tens of meters, and the deepest is no more than 350m. It is mostly used for mine risk removal and cannot be used for deep sea oil and gas exploitation

Embodiment
[0036] refer to figure 2 , when the motor A starts to work, the temperature of the motor oil inside the system gradually rises, and the heated volume of the motor oil gradually expands to push the volume of the capsule of the compensator B to become larger to balance the pressure difference between the inside and outside of the system; when the heat generated by the motor A decreases or stops , the temperature of the motor oil inside the system gradually decreases, and the volume of the motor oil gradually shrinks to push the volume of the capsule in the compensator B to shrink to balance the pressure difference between the inside and outside of the system.

The invention discloses a high-power oil-filled deep-diving underwater motor. The inside of the motor is separated from an external environment based on shaft driving sealing and static sealing of a motor housing. The inside of the motor is filled with mineral oil; and the mineral oil having high insulativity and lubricity is used as a medium for lubrication and cooling. The mineral oil plays a role in lubricating all parts inside the motor during the operation of the motor and taking away heat caused by the motor. The motor is used by matching a high-power oil-filled deep-diving underwater motor pressure compensator B and a heat-exchanging device C, thereby realizing internal and external pressure balancing of the system, maintaining the normal working temperature, and guaranteeing long-term, stable, and reliable work of the high-power oil-filled deep-diving underwater motor. The rated power of the motor can reach 1000 kW and the operating depth can reach 1500m. With the motor, the blank in domestic deep-water environment application can be filled and the purchasing cost can be lowered obviously; and the bottleneck constraint of the key technological resources in foreign companies can be avoided.
Description
technical field [0001] The invention relates to the technical field of oil-filled underwater motors, in particular to a high-power oil-filled deep-diving underwater motor. Background technique [0002] At present, with the dwindling of onshore oil and gas resources, the world has intensified the development of offshore oil and gas resources. my country's "Twelfth Five-Year National Strategic Emerging Industry Development Plan" also clearly promotes offshore engineering manufacturing to a national strategic level. [0003] my country's coastline length, continental shelf and 200 nautical mile exclusive economic zone area are among the top 10 in the world, and the total area of the jurisdictional sea area is nearly 3 million km 2 . At 135.17 million km 2 The area of petroleum-bearing basins identified on the continental shelf is nearly 700,000 km 2 , 16 large and medium-sized Cenozoic oil and gas basins have been delineated. The oil resources in these basins are 15-20 ...
