Hydraulic Pump

Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). It generates flow with enough power to overcome pressure induced by the load at the pump outlet.

Detailed Description for Hydraulic Pump

Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). It generates flow with enough power to overcome pressure induced by the load at the pump outlet. When a hydraulic pump operates, it creates a vacuum at the pump inlet, which forces liquid from the reservoir into the inlet line to the pump and by mechanical action delivers this liquid 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, in which the displacement (flow through the pump per rotation of the pump) cannot be adjusted, or variable displacement pumps, which have a more complicated construction that allows the displacement to be adjusted.

Hydraulic pumps are sources of power for many dynamic machines. Hydraulic pumps are capable of pushing large amounts of oil through hydraulic cylinders or hydraulic motors. In this fashion, the pump converts the mechanical energy of the drive (i.e. torque, speed) into hydrostatic energy (i.e. flow, pressure).

 

 

What is a Hydraulic Pump and Why Do You Need It?

Hydraulic pumps are sources of power for many dynamic machines. Hydraulic pumps are capable of pushing large amounts of oil through hydraulic cylinders or hydraulic motors. In this fashion, the pump converts the mechanical energy of the drive (i.e. torque, speed) into hydrostatic energy (i.e. flow, pressure).

Hydraulic pumps operate according to the displacement principle. This involves the existence of mechanically sealed chambers in the pump. Through these chambers, fluid is transported from the inlet (suction port) of the pump to the outlet (pressure port). The sealed chambers ensure that there is no direct connection between the two ports of the pump. As a result, these pumps are very suitable to operate at high system pressures and are ideal for hydraulics.

APPLICATIONS:

A hydraulic pump is used to transfer motive power, via hydraulic hoses, to a hydraulic motor or hydraulic cylinder. A hand operated hydraulic pump is used in a hydraulic jack, where many strokes of the pump apply hydraulic pressure to lift the ram. A backhoe uses an engine driven hydraulic pump to hydraulically drive the articulating parts of the mechanical hoe. hydraulic pumps are also used in the drive systems of tractors. They are also used in automatic transmissions.
