Hydraulic Pump
The
process of transferring of power from one point (the hydraulic pump) to
another point (linear or rotary actuator) is called hydraulics.
Hydraulic Pump is designed to convert mechanical power or motion into
hydraulic fluid power by producing a flow.
How does a hydraulic pump works?
Unlike other pumps, a hydraulic pump does not require external energy
source to perform the pumping action. The water is put to work to pump
itself. The pumps use kinetic energy of the water to push small amounts
of water into a reservoir. Two functions are carried out when a
hydraulic pump is in operation. One is the mechanical action that
creates a vacuum in the pump inlet. This allows the atmospheric pressure
to drive the liquid into the reservoir and to the inlet of the pump. The
other function is also the mechanical action in which liquid is released
into the outlet of the pump and then it flows into the hydraulic system.
Types of Hydraulic Pump:
- Piston Pump
- Vane Pump
- Gear Pump
- Positive Displacement Pump
Applications of Hydraulic Pump:
Hydraulic Pumps are used in a variety of industries and applications.
They are as follows:
- Forestry
- Agriculture
- Construction
- Material handling
- Washing machines
- Refrigerators
- Trucks
Features of Hydraulic Pump:
- Hydraulic pumps deliver high pressure fluid flow to the pump
outlet.
- A hydraulic pump, when powered by pressurized fluid, can rotate
in a reverse direction and act as a motor.
- Operating specifications, housing materials, and features are all
important specifications to consider when searching for hydraulic
pumps.
- Pump type and pump stages are the most important operating
specifications to consider when searching for hydraulic pumps.
- Additional operating specifications include continuous operating
pressure, maximum operating pressure, speed, horsepower,
temperature, maximum fluid flow, maximum fluid viscosity,
displacement per revolution and pump weight.
