Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. A hydraulic pump is a mechanical power source that converts mechanical energy into hydraulic energy (hydrostatic energy i.e. flow, pressure). Generates a flow with sufficient force to overcome the pressure induced by the load at the pump outlet.
When a hydraulic pump is running, it creates a vacuum at the pump inlet, which forces fluid from the reservoir into the pump inlet line and, through mechanical action, transports this fluid to the pump outlet and forces it into the hydraulic system. Hydrostatic pumps are positive displacement pumps, while hydrodynamic pumps can be fixed displacement pumps, where the displacement (flow through the pump per revolution of the pump) cannot be adjusted, or variable displacement pumps, which have a more complicated
layout that allows offset adjustment. balanced. However, hydrodynamic pumps are less common in everyday use. The hydrostatic pumps available in different versions work according to the principle of Pascal's law. It states that the increase in pressure at one point in the liquid, which is enclosed at rest, is transferred equally to all other points in the liquid, provided that the effect of gravity is not neglected.
(for static)Most pumps work in open systems. The pump draws oil from a reservoir at atmospheric pressure. It is very important that no cavitation occurs on the suction side of the pump. For this reason, the connection on the suction side of the pump has a larger diameter than the connection on the discharge side. When using several pump units, the suction connection of the pump is often combined.
Free flow to the pump is preferred (pressure at pump inlet atmin. 0.8 bar). The pump body is often in open communication with the suction side of the pump.
Hydraulic pumps are used in excavators, cranes, loaders, tractors, vacuum trucks, forestry equipment, graders, dump trucks, mining machinery, etc. Mobile applications use hydraulic pumps more often than industrial machines because electric actuators are not generally used for mobile machines.
