Abstract

A partial load type supercharged submersible pump applied to commingling production of multiple layers of natural gas in the same hoistway comprises an upper cover body, an annular support, a middle cover body, a cylindrical shell and a lower end cover which are sequentially arranged from top to bottom, a rubber ring is arranged on the outer circle of the annular support, a supercharged turbine is arranged in the upper cover body, and a center transmission shaft is arranged in the cylindrical shell along the center line. The upper end of the center transmission shaft penetrates through the annular support to be in transmission connection with the supercharged turbine, a plurality of hollow shafts arranged around the center transmission shaft are arranged in the cylindrical shell, a spiral blade is arranged on the inner wall of each hollow shaft, and a motor is arranged between every two adjacent hollow shafts. The partial load type supercharged submersible pump is exquisite in structure, large water pumping power under the small size is guaranteed, a plurality of partial load type supercharged submersible pumps can be connected in series for use at the same time, different submersible pump installation schemes can be customized according to different underground working conditions, and the working efficiency is improved while energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of submersible pumps and is applied to multi-layer unconventional natural gas (including coalbed methane, shale gas, tight sandstone tools, etc.), specifically a load-sharing pressurized submersible pump applied to the combined production of multi-layer natural gas and wells. Pump. Background technique [0002] Submersible pump is a kind of mechanical equipment that puts the pump body and motor into the water to work, and is an important equipment for deep well water extraction. Submersible pumps can be divided into two categories according to their working principles, one is impeller pumps, such as centrifugal pumps, and the other is positive displacement pumps, such as screw pumps. The centrifugal pump relies on the centrifugal force generated when the impeller rotates to transport the liquid. It has a simple structure and reliable operation, and can be used in various production and living scenes. Howeve...
