In a mechanical-hydraulic governor system, what is the purpose of the auxiliary oil pump?

In a mechanical-hydraulic governor system, the auxiliary oil pump plays a crucial role in ensuring reliable operation. The primary purpose of this pump is to deliver consistent and necessary oil pressure to the system, particularly during situations that require additional support for the main pump.

When considering the function of the auxiliary oil pump, it is important to note that it is designed to supplement the main oil pump's pressure when needed. This could occur during periods of high demand or during transient conditions when the main pump may not be able to maintain adequate pressure levels alone.

By boosting the pressure supplied by the main pump, the auxiliary pump helps to ensure that critical components of the hydraulic system, such as actuators and valves, receive the proper oil flow and pressure necessary for effective operation. This maintains the reliability of the governor system and contributes to stable control over the machinery being managed.

While the auxiliary oil pump does not directly serve as a fail-safe in case of the main pump's failure, it can enhance performance during specific operating conditions and for start-up procedures, thereby ensuring that the hydraulic governor functions effectively under a variety of situations.
