Utilization of Compressed Gas Heat for Fluid Compression and Movement in a Displacement Pump

详细

The issue of heat utilization from a displacement compressor of a displacement pump is considered. Analytical dependencies of changes in thermodynamic parameters in the compression and discharge processes in the pump are obtained for the case when heat is supplied from the compressor. The carried out numerical experiment proved that the discharge pressure can be 10 MPa or more in this pump, and the relative supply of fluid to the discharge line can reach up to 1% of the working chamber volume of the pump. It is established that utilization of the gas compression heat in hybrid power machines will improve the efficiency not only of the compressor, but also of the pump.
