A governor has an important role to play when it comes to controlling the speed of the marine engine. This instrument can either be hydraulic, electro-hydraulic, or electronic. Among the most widely relied upon types of governor in both the main engine and generator engine is the electro-hydraulic type Marine Governor.
Thanks to this instrument, the engine speed can be controlled smoothly from a remote space. This can either be a bridge or engine control room. But what does it take to get the most from a marine governor? Well, this is something that should never give you sleepless nights.
When handling the electro-hydraulic governor of a marine engine, it is highly advisable that you ensure the governor travel/output shaft connected to the fuel shaft has sufficient over-travel at each end of the terminal shaft. Skimping on this will either prevent it from giving more fuel at maximum fuel position. Worse, it might shut down the prime mover once the shaft is in minimum fuel position.
Things should not stop there since you must ensure the oil level and quality is correctly maintained. The viscosity of the oil inside the governor should be in the range of 20 cst to 65 cst at normal operating temperature. As for the continuous operating temperature of the governor oil, it should be maintained at 60 Deg c to 93 Deg c.
At times you might have to test the governor after overhauling. When this is the case, ensure all linkages are proper and oil level is up to the mark. In case the governor malfunctions, you need to hold the output shaft with a serration wretch to manually control the speed.
The Bottom Line
Ship engineers must always be familiar with the planned maintenance of the governor if it is to function effectively. At no time should you rely on a faulty engine since it might result in over speeding of the engine leading to fatal accidents. That’s something you never want to make do with at any particular time.
