What is the primary function of a pump in hydraulic systems?

The primary function of a pump in hydraulic systems is to convert mechanical energy into hydraulic energy. This process is essential because pumps create the necessary fluid flow and pressure within the hydraulic system, allowing it to perform various tasks such as lifting, pushing, or controlling machinery. By transforming the mechanical input energy from engines or motors into energy that moves and pressurizes hydraulic fluid, the pump enables the system to operate effectively.

In hydraulic applications, this conversion is vital for maintaining the efficiency and functionality of the entire system. As the pump moves the hydraulic fluid, it generates the pressure required to transmit force through the fluid to other components, such as actuators and cylinders. This action is fundamental for accomplishing tasks common in various industries, like construction, manufacturing, and aviation.
