SPF-708. Universal test bench 7kw

SPF-708. Universal test bench for diesel systems 7 kW with measuring unit for 8 sections

The bench is intended for testing and adjusting the devices of the power system of diesel engines during their repairs and maintenance.

TYPES OF TESTING

The test bench allows the following types of tests and adjustments:

• Determination of the volumes of fuel injection doses for different speeds of the high-pressure fuel pump shaft corresponding to:

– starting the engine (starting dose),

– idling (idling dose),

– the beginning and the end of positive and negative adjustments,

– the rated motor power (nominal, so-called measuring dose), and speed, which determines the so-called high-speed characteristic of the fuel high-pressure pump;

• Determination of the rotation speed of the start and end of the fuel injection shut-off by the speed regulator (the maximum number of idling speed), which determine the adjustable speed range;
• Geometric start of compression , and angular gaps between sections of the high pressure fuel pump ;
• Spread (unevenness) of the fuel doses 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 of the feed pumps under test;
• Checking the injection pressure of the feed pumps under test;;
• Checking the performance of feed pumps under test ;
• Checking the tightness and transmittance of the fuel filter.
