+86 15359408275PSG Hydraulic-Mechanical Governor - Woodward PSG Governor Series
Woodward 8561-701 is identified as a PSG hydraulic-mechanical governor for prime-mover speed regulation. The PSG family combines a speed-sensing mechanism, hydraulic control action and mechanical output in a compact engine-driven assembly.
In service, Woodward 8561-701 responds to changes in shaft speed and adjusts the connected fuel or energy-control linkage. The installed droop or isochronous arrangement, speed-setting mechanism and linkage geometry determine how the governor participates in generator, marine, pump or compressor duty.
Reliable operation depends on the correct drive rotation, mounting orientation, oil condition, output-shaft travel and linkage alignment. These items must be checked against the removed governor because visually similar PSG configurations can have different internal settings.
No exact public Woodward datasheet was located for order number 8561-701. Record the complete nameplate, serial number, drive data, speed range, lever travel and application before ordering or commissioning a replacement.
