| Summary: | The purpose of the work is to propose methods and
means for determining the technical condition of fuel
equipment. A method is proposed for determining
the technical condition of the high-pressure pump and
injectors of the marine diesel MAN B&W 6S50MC-C by
changing the maximum fuel pressure and temperature of
the outer surface of the pipeline. For fuel equipment with
a maximum pressure in the pipeline from 50 to 150 MPa,
the permissible pressure change zone is determined. A
formula is proposed that additionally takes into account
the cyclic fuel supply and its mass when estimating the
temperature from its compression by the pump plunger.
The fuel temperature during compression is determined
depending on the pressure value. The calculation of
the heat transfer process through the pipeline wall and
from the heated wall surface to the air is performed. A
portable RGK PL12 pyrometer is proposed to measure the
temperature on the pipeline surface and determine the
technical condition of the fuel equipment. The permissible
temperature change zone of the pipeline surface is given, according to which the serviceable condition of the pump
and the nozzle is evaluated. |
