| description | The paper considers a new scheme for reducing pressure fluctuations on the gas injection line in the
compressor section of a hybrid power machine, highlights the main control volumes for the compressor
and pump sections. Based on the General laws of conservation of energy, mass, motion and the
equation of state, a mathematical model for calculating the control volumes of the compressor section of
constant and variable volumes is developed. Based on the use of the equation of continuity of motion
and energy, taking into account the energy loss for friction and external heat transfer, a mathematical
model of the gas flow in the interstage communications of the compressor section is developed. Based
on the use of Hooke’s equations of mass, volume and motion, a mathematical model of the compressor
section in the pump mode is developed. Considering the fluid flow in the connecting pipelines as
quasi-stationary, their calculation is carried out on the basis of the Bernoulli equations. The developed
mathematical model and schematic diagram can be used in the calculation of new efficient designs of
both piston compressors and hybrid power machines. |
