Abstract

A system for the recirculation of gas in air gaps of rotating machines via an ejector, a motor and a pump, including circulating a gas extracted from a gas-extraction unit which is located in the pump. This gas circulates in the gap between the rotors and the stator of the motor. The rotor of the motor is coupled to the shaft of the pump, and in one or more embodiments the gas from the gas-extraction unit flows from the pump to the ejector in order to be injected into the air gap between the rotor and the stator, thereafter returning to a process line. In one or more embodiments, the gas from the gas-extraction unit flows from the pump, and is injected directly into the air gap, and thereafter passes via the ejector in order to recirculate the gas to the process line.
