An electronic pressure control governor regulates pump pressures by adjusting

An electronic pressure control governor regulates pump pressures by adjusting

• A. The engine speed
• B. The discharge valve position
• C. Suction pressure
• D. Ambient temperature

Answer: (A)

Electronic pressure control governors regulate pump pressures by adjusting engine speed. They continuously sense the discharge pressure, compare it to the desired setpoint, and send a signal to the engine governor to speed up or slow down the engine. Increasing engine speed raises the pump’s head and discharge pressure, while decreasing speed lowers them, keeping the system pressure within the target range. Discharge valve position can influence flow, but the electronic governor’s job is to control pressure by modulating engine RPM, not by constantly coordinating valve openings. Suction pressure and ambient temperature aren’t the primary controllable inputs for maintaining the discharge pressure in this setup; suction varies with demand and layout, and ambient temperature doesn’t directly regulate pump pressure.
