Abstract
Official abstract text for this publication.
A motorcompressor comprising an electric motor, a load, a shaft assembly, the electric motor and the load being mounted on the shaft assembly, a casing configured to completely house the electric motor, the load and the shaft assembly for its entire length, a divider located in the casing to define a motor chamber and a load chamber, the divider comprising at least a pumping device configured to transfer a part of the fluid present in the motor chamber to the load chamber so as to obtain in the motor chamber a pressure that is lower than a pressure at a load inlet.
First claim
Opening claim text (preview).
The invention claimed is: 1. A motorcompressor comprising: an electric motor; a load; a shaft assembly, the electric motor and the load being mounted on the shaft assembly; a casing configured to completely house the electric motor, the load and the shaft assembly; and a divider located in the casing to define a motor chamber and a load chamber, the divider comprising at least a pumping device configured to transfer a part of a fluid present in the motor chamber to the load chamber so as to obtain in the motor chamber a pressure that is lower than a pressure at a load inlet, wherein the pumping device is an ejector, and wherein the ejector comprises a motive fluid nozzle fluidly connected to an inlet of the load or to a bleeding tap present at an upstream stage of the load. 2. The motorcompressor of claim 1 , wherein the ejector comprises an ejector inlet fluidly connected to the motor chamber and an ejector outlet fluidly connected to the load chamber. 3. The motorcompressor of claim 2 , wherein the motive fluid nozzle is located upstream to a converging inlet nozzle. 4. The motorcompressor of claim 1 , wherein the motive fluid nozzle is located upstream to a converging inlet nozzle followed by a diverging outlet nozzle, the converging inlet nozzle and the diverging outlet nozzle being connected at a diffuser throat. 5. The motorcompressor of claim 1 , wherein the shaft assembly is a single shaft or it is formed by a plurality of parts torsionally connected each other. 6. Subsea assembly comprising a motorcompressor according to claim 1 .
