Different Types of RC Hydraulic Pump

Different Types of RC Hydraulic Pump
Hydraulic pumps convert the mechanical energy & motion to hydraulic
fluid power. The basic idea is very simple – a force that is applied at one
position is transmitted to another position by using the incompressible
fluid, like oil that can’t be compressed but rather is expatriate when
pressure is applied.
The reservoir, hydraulic cylinder, & pump make up the 3 major parts of
the hydraulic pump. Pumping hydraulic fluid from the reservoir to the
bottom cavity of the cylinder causes the piston rod to be pushed up,
which pushes the fluid in the other cavity back to the reservoir. It
procedure makes the chamber & extends the piston to its full length.
Pumping hydraulic fluid to the upper chamber of the cylinder pushes
the piston rod down, pushing the oil in another chamber back to the
reservoir, completing the cycle.
Popular RC Hydraulic Pump Types
• Piston pumps, vane pumps, & gear pumps are the primary types of
the hydraulic pumps

• Gear pumps – Uses gears to pump fluid by the displacement.
Hydraulic gear pumps are one of the common types of pumps. There
are numerous advantages & disadvantages to gear pumps. The
advantages are - high pressure, high speed, & quiet operation. The
disadvantages are - the use of four bushings in liquid area & fixed end
clearances.

• Rotary vane pumps – are recognized for the positive-displacement.
They include a ring mounted inside the cylindrical case. There are an
array of radial slots in which sliding vanes are located. Mounted to the
case is the ring & the vanes are intended to press against the inside wall
of the case. The hydraulic pressure & spring force or centrifugal force as
the ring is alternated will cause the blade to be forced against, the wall.
• Axial piston pumps are positive displacement. There are numerous
pistons in a circular arrangement in a cylinder block.
• Radial piston pumps - a circular arrangement of hydraulic pistons, and
valves which allow pressures greater than 650 Bar (~10,000 psi) to be
built.
• Screw pumps - positive displacement pumps. Have one or more
screws that rotate to transfer high or low viscosity fluids along an axis.
Some RC hydraulic pumps are manual and some are powered by
electricity, compressed air, or petrol. Manual hydraulic pumps are
countless because they have portability because don't need an
additional power supply. They are perfect for occasional tasks but they
do lack the power & speed of powered pumps. They are also labor-

intensive. RC Hydraulic pumps and RC hydraulic excavators have all
sorts of uses but if you find that you need to purchase one yourself,
make sure that you do your research & get the right one.
