Massachusetts Oil Burner License Practice Test

What are the functions of fuel units (oil pumps)?

1. Locate the oil source

2. Move oil from the tank and regulate pressure

3. Heat the oil before combustion

4. Store oil temporarily

The correct answer is: Move oil from the tank and regulate pressure

The correct choice identifies the essential functions of fuel units, specifically oil pumps, in heating systems. Oil pumps are designed primarily to move oil from the storage tank to the burner nozzle, facilitating the combustion process necessary for heating. Additionally, these pumps play a critical role in regulating the pressure of the oil as it travels through the system, ensuring that it is delivered at the right pressure needed for efficient and effective combustion. Understanding the hydraulic mechanics of oil delivery is crucial, as any issues with the oil pump can lead to insufficient fuel flow, affecting the performance of the heating system. It's important for anyone working with oil burners to recognize that without the proper movement and regulation of oil by the pump, the entire heating system could malfunction, leading to inefficiencies or failure to reach optimal heating performance. While locating the oil source is part of the system setup, and heating the oil may be relevant in some contexts, these actions are not primary functions of the oil pump itself. Similarly, storing oil temporarily is not a function associated with oil pumps, which are specifically designed to facilitate the movement and delivery of fuel rather than to store it.
