Assay test bench for testing high-pressure fuel pumps
POWER OF THE BASIC DRIVE 7,5kW
MEASURING UNIT OF 8 MEASURING FLASKS
The bench is intended for testing and adjusting the devices of the power system of diesel engines during their repairs and maintenance.
The assay test bench allows the following types of tests and adjustments:determination of the volume of fuel injection doses for different shaft speeds of the high-pressure fuel pump, corresponding to:
- engine start (starting dose),
- idling (dose of idling),
- the beginning and end of the positive and negative adjustment,
- engine rated power (nominal, so-called measuring dose), as well as revolutions, defining the so-called high-speed characteristic of a high-pressure fuel pump;determining the speed of rotation of the start and end of the fuel injection shutdown by the rotation speed regulator (maximum idling speed), defining the so-called adjustable speed range;geometric start of compression (adjustment of the preliminary stroke), as well as angular gaps between sections of the high-pressure fuel pump;scatter (non-uniformity) of doses of fuel injected by different sections of the high-pressure fuel pump, which should not exceed 2% of the nominal dose;operation of the electromagnetic shut-off valve;checking the suction discharge of the feed pumps;checking the injection pressure of the feed pumps;checking the performance of feed pumps;check of tightness and permeability of the fuel filter.
