Where Is The Hydraulic Pumps Used?

In fact, every hydraulic transmission system is like this. A hydraulic pump is a device that converts mechanical energy into hydraulic energy. Hydraulic energy is a combination of pressure and flow. A hydraulic pump can be any device that can input force to generate pressure, and pressure can generate flow.

The basic hydraulic pump is a manual pump for any low-power applications where the prime mover is too expensive or unavailable. Hand pumps can be used to assist power, such as releasing hydraulic brakes on tractors towing agricultural implements. In contrast, hand pumps can be used as the main hydraulic source, for example on hydraulic power tools or bench-top hydraulic presses. Due to the low power input (most people cannot get more than one tenth of horsepower in a few seconds), the application of hand pumps is very slow, although the pressure may reach 10,000 psi or higher.

Most hydraulic pumps have mechanical inputs from internal combustion engines or electric motors. These prime movers input their mechanical power into the hydraulic pump in a rotating manner. The input shaft of the pump will be connected to the gears, vanes or pistons of the hydraulic pump, where they will rotate or reciprocate to transfer pressure (force) to the hydraulic oil. As long as the force (pressure) generated by the pump is high enough, flow will be generated at a rate determined by the displacement of the pump and the rotational speed of the pump.

Hydraulic pumps are used on all possible mobile or industrial hydraulic machines. Hydraulic pumps are used in excavators, cranes, loaders, tractors, vacuum trucks, forestry equipment, graders, dump trucks, mining machinery, etc. Compared with industrial machinery, the use of hydraulic pumps in mobile applications is more efficient because electric actuators are generally not used in mobile equipment machinery.

Hydraulic pumps are still widely used in industrial environments. Injection molding machines, presses (shearing, punching or bending, etc.), material handling, elevators, conveyors, mixers, forklifts, pallet jacks, foundries, steel plants, slitting machines, etc. The more stringent the application, the more likely it is to be powered by a hydraulic pump.
