Influence of Deformation, Mass Transfer, and Heating on Pump Compression


Compression of the working fluid in bulk-action pumps (such as piston, gear-driven, and plate-type pumps) under the action of deformation, mass transfer, and heating is considered. A method of calculating the compression is developed, for each factor and for the combination of deformation and mass transfer. The effectiveness of compression is analyzed for each case.
