Abstract
A multistage centrifugal pump includes an upstream housing and a downstream housing. The upstream housing and the downstream housing each have a first end, a second end and a plurality of turbomachinery stages. Each of the plurality of turbomachinery stages includes a diffuser and an impeller. A compression bulkhead is connected between the second end of the upstream housing and the first end of the downstream housing. The compression bulkhead applies a compressive force to the diffusers within the upstream housing.
Claims20
A multistage centrifugal pump comprising:
- an upstream housing, wherein the upstream housing comprises:
- a first end;
- and
- a second end;
- a plurality of turbomachinery stages within the upstream housing, wherein each of the plurality of turbomachinery stages within the upstream housing includes a diffuser and an impeller;
- a downstream housing, wherein the downstream housing comprises;
- a first end;
- and
- a second end;
- a plurality of turbomachinery stages within the downstream housing, wherein each of the plurality of turbomachinery stages within the downstream housing includes a diffuser and an impeller;
- and
- a compression bulkhead connected between the second end of the upstream housing and the first end of the downstream housing, wherein the compression bulkhead applies a compressive force to the diffusers within the upstream housing.
An electric submersible pumping system for use in pumping fluids from a wellbore, the electric submersible pumping system comprising:
- a motor;
- and
- a multistage centrifugal pump driven by the motor, wherein the multistage centrifugal pump comprises:
- a shaft;
- an upstream housing, wherein the upstream housing comprises:
- a first end;
- and
- a plurality of turbomachinery stages within the upstream housing, wherein each of the plurality of turbomachinery stages within the upstream housing includes a diffuser and an impeller;
- a downstream housing, wherein the downstream housing comprises:
- a first end;
- and
- a second end;
- a plurality of turbomachinery stages within the downstream housing, wherein each of the plurality of turbomachinery stages within the downstream housing includes a diffuser and an impeller;
- and
- a compression bulkhead connected between the second end of the upstream housing and the first end of the downstream housing, wherein the compression bulkhead applies a compressive force to the diffusers within the upstream housing.
A method for assembling a multistage centrifugal pump, the method comprising the steps of:
- providing an upstream housing that includes a first end and a second end;
- loading a plurality of impellers and diffusers into the upstream housing;
- and
- threading a first end of a compression bulkhead into a second end of the upstream housing.
