Question 1 of 27070

The major cause of trouble in a mechanical-hydraulic governor is contamination of the hydraulic fluid by __________.

🔍 Key Concepts

• Mechanical-hydraulic governor operation – how the hydraulic system uses clean oil to transmit motion and maintain speed • Effects of contamination in hydraulic systems – what types of foreign material cause sticking, wear, or plugging of small passages and orifices • Difference between solid contaminants and miscible liquids (like fuel or water) in a hydraulic oil system

💭 Think About

• Think about which contaminant is most likely to block very small oil passages, stick valves, and score close-clearance parts in a governor • Consider which of these choices is most commonly present in an engine room environment and easily introduced into an oil system through poor maintenance practices • Ask yourself which contaminant is typically the primary concern mentioned in hydraulic equipment manuals and maintenance instructions

✅ Before You Answer

• Verify which option would be solid particles that can plug orifices and damage precision parts • Check which contaminants are less likely to mix easily with governor oil under normal conditions • Confirm from your engineering knowledge or notes which contaminant is usually emphasized as the main cause of hydraulic system trouble
