DETERMINATION OF OPERATING VALUE INDICATORS OF HYDRAULIC DENSITY OF RESTORED PLUNGER PAIRS OF HIGH-PRESSURE FUEL PUMPS OF SPECIAL VEHICLES
Abstract
This article examines the operating characteristics of plunger pairs used in high-pressure fuel pumps of diesel engines, their wear causes, and restoration methods. The reasons for the sharp decrease in the service life of plunger pairs in the conditions of Central Asia with a hot climate and high dust content are cited. The limits of the operational value of the hydraulic density of the reconstructed plunger pairs have been determined.
Keywords
plunger pair, high-pressure fuel pump, hydraulic density, operation, restoration, value limits, repair.
