Modularized shaftless driving deep-sea mining multiphase pump

Abstract

The invention discloses a modularized shaftless driving deep-sea mining multiphase pump which is of a shaftless machine-pump integrated structure and is formed by connecting a plurality of same hydraulic stage modules end to end, each hydraulic stage module is provided with a lubricating and cooling circulation structure, and the multiphase pump can be intelligently regulated and controlled. The multi-phase pump has the beneficial effects that shaft driving is converted into motor driving arranged in the pump by adopting a shaftless technology, the situation that the multi-phase pump is easy to block is reduced, and the conveying efficiency of particles is improved; through the modular design of the pump, each hydraulic stage is independent, and maintenance and replacement are facilitated when a certain unit stage breaks down, so that the working and safety problems caused by the faults of the pump are reduced, the production efficiency is improved, and the economic loss is reduced; the shaftless multiphase pump can change the lift according to different water depth working conditions so as to improve the working efficiency.

Description

technical field [0001] The invention belongs to the technical field of mining mixing pumps, in particular to a modular shaftless driving deep-sea mining mixing pump. Background technique [0002] The existing mixed pump has multiple stages in series and a single working condition cannot be applied to the working environment of different water depths. If there is a problem with the first hydraulic stage in the pump body, it will affect the overall particle transportation and cause the work to stop and be in the process of maintenance and replacement. It is more troublesome and difficult, and at the same time, the radial size of the existing pump body flow channel is large, and the diffusion is serious, which cannot efficiently transport particles, which also leads to the problem that the complex flow channel is prone to blockage of the mixed pump through the long path, which makes the deep sea mining. The efficiency of transportation is reduced, and the follow-up maintenance ...

Problems solved by technology

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a shaftless mixed pump used in deep-sea mining to adapt to change the engineering head through a specific adjustment mechanism according to the water depth working conditions to improve work efficiency. Shaftless pump technology is used to transform the shaft drive into the motor drive arranged in the pump, which reduces the easy clogging of the mixed pump and improves the conveying efficiency of particles. At the same time, through the modular design of the pump, each hydraulic stage is independent, It is convenient for maintenance and replacement when there is a problem such as a failure at a certain unit level, so as to reduce the work and safety problems caused by the failure of the pump, thereby improving production efficiency and reducing economic losses, etc.
