Submerged pump system

Abstract

The invention provides a submerged pump system, which comprises a cylindrical submerged tower (100), a first water hard conduit (210), a first submerged pump (310), a second water hard conduit (220), a second submerged pump (320) and a water outlet conduit (400), wherein the first water hard conduit (210) is fixedly arranged in the submerged tower (100) through a reinforcement plate (110) and extends along the submerged tower (100); the first submerged pump (310) is fixedly arranged at one end inside the submerged tower (100) and is connected with the first water hard conduit (210); the second water hard conduit (220) is fixed arranged in the submerged tower (100) through the reinforcement plate (110), and extends along the submerged tower (100); the second submerged pump (320) is fixedly arranged at one end inside the submerged tower (100) and is connected with the second water hard conduit (220); and the water outlet conduit (400) is arranged at the other end of the submerged tower (100), and is respectively connected with the first water hard conduit (210) and the second water hard conduit (220).

Description

technical field [0001] The present invention relates to a submersible pump system. Background technique [0002] When the self-elevating platform is in the working state, it is in a standing state, and the sea bottom door is out of the water surface, so seawater cannot be pumped for use by the platform, so a special pumping system is required to pump water up from the water surface to maintain the normal operation of the generator and other systems. Required cooling water needs. At present, the pumping systems commonly used on drilling ships mainly include: truss lifting submersible pump systems and hose coil submersible pump systems. [0003] The liftboat platform is famous for its lightness and flexibility, but the hull space is limited, and equipment layout and weight control are two major problems. Although the truss lifting submersible pump system has a strong ability to resist wind and waves, it is difficult to meet the volume and weight requirements of the liftboat ...

AI Technical Summary

Problems solved by technology

Although the truss lifting submersible pump system has a strong ability to resist wind and waves, due to its large size and heavy weight, it is difficult to meet the volume and weight requirements of the liftboat platform

like figure 1 and figure 2 As shown, it is difficult to meet the restrictions of the liftboat platform on the layout and structure of the boat room by using the truss lifting submersible pump system

In addition, due to the large structure of the truss lifting submersible pump system, under the condition of large wind and waves, its volume subjected to wind and waves is large, and the impact force it receives is also large. Stability is also greatly affected by

[0004] like image 3 As shown, in order to meet the restrictions on the layout and structure of the liftboat platform, the hose coil submersible pump system can also be used, but its ability to resist wind and waves is poor, and it often cannot work normally when there is a certain amount of wind and waves
