MK6 Test Stand

The Merlin MK6 series are designed for the calibration of larger, single and multi-cylinder fuel injection pumps as fitted in marine, rail and heavy duty industrial applications.

Thyristor—controlled DC motor provides infinitely variable stepless drive in both directions, with pre-selection of speeds. Zero droop from maximum to minimum load provides for accurate governor setting.

Two 2.5 Kw heater elements fitted in test oil tank. Microprocessor-based digital controller with thermo-couple.

A selection of mobile injector mount/calibration units, camboxes and fuel pump mounting brackets are available.

Also available with either integral or free standing remote control unit and fully compatible with Merlin’s mobile calibration rig (C415) and injector rig (R415).

INJECTION

Injection is via the R415 Mobile Cylinder Injector Mounting Unit.

• The unit will accept standard ‘T’, ‘S’ and orifice plate test injectors for multi-cylinder fuel pumps.
• A heavy duty damper and valve selector system is incorporated for testing single cylinder fuel pumps.
• Single cylinder test injectors are positioned remotely on a universal fixture mounted on the test bench bed.

METERING

Metering is via the C415 Mobile Calibration Unit.

• Solenoid operated bottom fill/bottom drain graduates.
• The unit has 12 x 0-1000mm³graduates for multi-cylinder pumps.
• 3 additional graduates as follows for single cylinder pump testing:
• 200mm³
• 1000mm³
• 7000mm³
• Electronic shot count unit range 1 to 9999 adjustable in single selectable increments, display indicates decreasing Count down.

Full Acoustic enclosure can be provided.
