Two phase pump with no moving parts - uses compressed gas to force hot corrosive fluids through dynamic valve

摘要

The two phase pump comprises two containers (R1 and R2), pipes (AE1, A2, E, C1, C2) and a dynamic valve (SD). In the admission phase,the fluid runs through the pipe (AE1) into the container (R1) and through the dynamic valve and pipe (A2) into the container (R2), where the pressure is p1=p2=0. In the evacuation phase, compressible gas is introduced through pipes (C1 and C2) into the containers, when the condition becomes p1>p2. ADVANTAGE - Pump without moving parts made of non-conventional material (e.g. glass, graphite) and capable of handling hot corrosive fluids.
