This paper presents a new power system for reverse osmosis desalination, which is composed of a Stirling engine driven booster pump and a reciprocating piston pump rigidly connected. Firstly, the physical model is established by SolidWorks, and then the frequency of reciprocating motion of piston is calculated through the principle of piston component motion. Then, the UDF file of piston motion is compiled. Then, CFD analysis is carried out by FLUENT software to select the standard the temperature field, velocity field and pressure field in the pump chamber of Stirling engine are simulated by coupled method, and the output work of the engine is studied. The results show that the gas movement in Stirling engine is stable, the pressure at the discharge port of reciprocating pump is greater than the required osmotic pressure, and the whole power system can operate normally.
