Investigation of temperature fields in the compartments of gas pumping units (GPU ) and in the reference design of the engine and a supercharger

Abstract

It has been found that the thermal condition in the engine compartment (E) with a free power turbine (PT) and the blower compartment (H) under operating conditions different from the thermal state in said compartments during alignment rampart compound CH-N. According to the instruction alignment during the temperature drop in the compartments A + ST and H should not exceed 10 ° C. Clearly, the large temperature difference between the compartments when the alignment and operational modes SBS leads to thermal deformation of the frames A and CT as well as the housing H, which in turn causes alignment errors and increase in the SBS vibration as a whole. Was tasked to investigate the temperature field in the compartments and supporting structures GPA.
