FAQ Hydraulic Pumps
Hello dear colleagues,
Hydraulic pumps are devices used in a hydraulic system to control motion and power. They transport fluid (usually oil) from one place to another, creating energy in the process. This energy is typically used to activate a cylinder or hydraulic motor at an output end.There are different types of hydraulic pumps, each being more suitable for certain applications. Here are a few examples:
Gear Pumps: This type of pump operates on the principle of compressing fluid between two gears. One gear is turned, which turns the other gear. This transfers the fluid from one gear to the other and pushes it out to the pump's outlet. These pumps are typically simple and cost-effective, used in a broad range of applications.
Vane Pumps: Vane pumps have a set of vanes that move inside a rotor. As the rotor turns, the vanes are pushed outwards and create a series of cells between the rotor and the pump's casing. Fluid enters one of these cells, and as the rotor turns, the cell compresses, pushing the fluid out.
Piston Pumps: These pumps operate on the principle of a piston drawing in and compressing fluid. They're often used for high-pressure applications and come in various designs: like eccentric shaft piston pumps, axial piston pumps, and radial (swashplate) piston pumps.
Applications of hydraulic pumps are diverse and typically found in industrial machinery and mobile equipment, such as construction equipment, agricultural machinery, aircraft systems, and automobiles. For instance, the hydraulic cylinders that move an excavator's arm up and down are actuated by pressurized oil from a hydraulic pump.
The success of hydraulic pumps depends on a range of factors such as pressure capacity, efficiency (minimum energy input for maximum energy output), operating speed, and lifespan. These factors determine whether the pump is suitable for the application.
