A feed device for a two-phase fluid pump enabling the pump to be supplied with a two-phase fluid having characteristics, especially the volumetric ratio of the gaseous phase to the liquid phase, compatible with the operating characteristics of the pump. The device has a main pipe (10a) and a plurality of auxiliary pipes (10b, . . . 10i) parallel to the main pipe. Each of the pipes can be connected to an upstream supply line of two-phase fluid, and to the downstream pump (6), each of the pipes having an isolation and flow regulating gate (11a, . . . 11i) at its upstream inlet and an isolation and flow regulating gate (12a, . . . 12i) at its downstream outlet, each of the pipes also having means (16a, . . . 16i; 17a; 17i) for introducing a carrier liquid, such as water.
A feed device for a two-phase liquid pump for supplying to the inlet of the pump a two-phase fluid having a volumetric ratio of gaseous phase to liquid phase compatible with the operating characteristics of the pump, said device comprising, a main pipe having an inlet adapted to be connected to a source of two-phase fluid and an outlet adapted to be connected to the inlet of the pump, a plurality of auxiliary pipes connected in parallel to said main pipe, each of said auxilliary pipes having an inlet adapted to be connected to the source of two phase fluid and an outlet adapted to be connected to the inlet of the pump, each of said pipes having an isolating and flow regulating gate between the outlet thereof and the inlet of the pump, and means for introducing a carrier liquid into each of said pipes.
