SUBMERSIBLE MULTI-PHASE PUMP OR COMPRESSOR WITH A MAGNETIC CLUTCH AND COOLING OR LUBRICATION THROUGH LIQUID OR GAS DISTRIBUTED FROM A TECHNOLOGICAL FLUID

摘要

1. Submersible system for fluids, designed to work when immersed in a mass of water, the system includes an electric machine, an injection part comprising a body of the discharge part having an inlet channel leading to a rotor for the fluid, while the rotor for the fluid is connected to an electric machine and held rotatably in the housing by means of a bearing in the housing; a fluid separation system that receives a multiphase fluid and feeds the multiphase fluid flows to the inlet and supplies jets of a substantially liquid stream separated from the multiphase fluid to the bearing. 2. The fluid immersion system of claim 1, wherein the fluid rotor is rotatably held in the housing by the first said bearing near one end of the fluid rotor and a second bearing not far from the second end of the fluid rotor, and wherein the fluid separation system transmits a fluid a stream separated from a multiphase flow to the first bearing and the second bearing. 3. The fluid immersion system of claim 1, wherein the liquid stream recovered from the multiphase fluid has a temperature that is lower than the temperature of the bearing. The submersible fluid system of claim 1, wherein the fluid separation system delivers fluid into a cavity surrounding the fluid rotor near the drive end. A fluid immersion system according to claim 4, wherein the drive end of the fluid rotor is connected to the rotor of an electric machine provided in the electric machine by means of a coupling, and the fluid separation system additionally supplies the fluid flow into the gap between the coupling part on the fluid rotor and the coupling part on an electric rotor
