Pumps In Hydraulic System
Pumps in hydraulic system
Hydraulic pumps convert electrical energy into fluid pressure by using an electric motor to drive the pump. They are necessary for all hydraulic drives. The fluid pressure is then delivered by hydraulic fluid to cylinders and actuators and hydraulic motors at the required pressure level and volume.
How many types of hydraulic pumps are there?
Four types of gear pumps exist Internal gear pumps, Lobe pumps, External gear pumps, and Gerotor pumps. External Gear Pumps: External Gear pumps rely on the counter-rotating motion of meshed external spur gears to impart motion to a fluid. They are generally fixed-displacement designs, very simple and robust.
Where are hydraulic pumps used?
Generally speaking, hydraulic pumps are used more frequently in cases where the application is severe. Hydraulic pumps are most commonly found in steel mills, foundries, lifts, conveyors, injection molding machines, shear and stamping presses, mixers, forklifts, pallet jacks and more.
