Bench for testing diesel fuel injection equipment SDM-8-7,5

Manufactured by Bonus

Our organization, Bonus LLC, is engaged in production of SDM benches for repair, diagnostics and adjustment of diesel fuel equipment, high pressure fuel pumps (HPFP), as well as Common Rail injectors.

Multi-purpose benches, which use asynchronous electric motor with “Mitsubishi” frequency converter, allowing to make diagnostics and adjustment of all brands of high-pressure fuel pumps (HPFP) of diesel engines of domestic and foreign manufacture.

An electric drive with a Mitsubishi frequency converter enables the output shaft speed of the bench to be smoothly adjusted. Keeps the rotation speed stable with minimum deviations, meeting ISO standards, compact and easy to operate.

Diagnostics is made by reproducing the rotation speed of the drive shaft of a high-pressure fuel pump (HPFP), cycle feed, fuel consumption of the test facility, the fuel charging (injection) timing angles, turn of the injection timing device, deviations of the injection timing angles.

The following operations can be performed on the benches:

testing and adjustment of in-line HPFPs with independent lubrication system, with the number of sections up to eight, as well as distribution type HPFPs with the number of supply fittings up to eight by controlling the following parameters and characteristics:

• amount and uniformity of fuel supply by sections (capacity of pump sections);
• the HPFP shaft rotation speed when the regulator starts operating;
• the angle of fuel injection and supply by the turn of the HPFP shaft and alternation of supply by HPFP sections;
• the actual injector spray angle (when diagnosing);
• characteristic of the timing coupling.

These benches allow you to serve the HPFPs manufactured by: YaZTA, YaZDA, NZTA, RAAZ, ChZTA, AZTN. By special order, the bench is completed with tooling for diagnostics and adjustment of foreign-manufactured HPFP.

The stands are equipped with an electronic control system.
