This presentation summarizes various hydraulic-based components: 1. Hydraulic cranes use pressurized water to lift heavy loads up to 2500 kN through fixed cylinders and sliding rams connected to pulley blocks. 2. Hydraulic lifts use pressurized fluid and Pascal's law to transport passengers and goods between floors in buildings. They are used in wheelchairs, trucks, material handling, and industrial applications. 3. Hydraulic accumulators store pressurized hydraulic fluid supplied by external sources like springs, weights, or compressed gas, in order to smooth out fluctuations in demand for pumps and hydraulic systems.

2. HYDRAULIC CRANE
The hydraulic crane is used for
transferring or raising heavy loads.
It can be used up to loads 2500 kN.
It is widely used in loading and
unloading ship, warehouses,
workshop, heavy industries and
dock sidings

3. CONSTRUCTION

4. WORKING
During the lifting the load by crane,
the high pressure water is
admitted into the fixed cylinder of
jigger.
The pressuriesed water forces the
sliding ram to move right with movable
pulley bock.

5. WORKING
So that the distance between
two pulley blocks increases
Which causes the wire passing over
the guide pulley is pulled by the
jigger and hence the load attached
to hook is lifted.

6. HYDRAULIC LIFT

7. WHAT IS HYDRAULIC LIFT?
Hydraulic lift is a device used for carrying
passenger or goods from one floor to another in
multi- storied building to raise heavy objects.
• Pascal's law is a principle in fluid mechanics that
states that pressure exerted anywhere in a confined
incompressible fluid is transmitted equally in all
directions throughout the fluid such that the
pressure variations (initial differences) remain the
same.
• This law is applied to lifts.

9. HYDRAULIC ACCUMULATOR
A hydraulic accumulator is a
pressure storage reservoir in
which a non-
compressible hydraulic fluid is
held under pressure by an
external source. The external
source can be a spring, a raised
weight, or a compressed gas.

10. INTRODUCTION
• A Hydraulic Accumulator is energy storage device.
• The external source used can be a spring, a raised
weight, or a compressed gas.
• The main reasons that an accumulator is used in
a hydraulic system, is that the pump doesn’t need
to be so large to cope with extremes of demand
and supply circuit can respond quickly to any
temporary demand and to smooth pulsation.

13. HYDARULIC SYMBOLS

14. APPLICATIONS
Accumulators are devices used to store fluid power to do the
following:
 Agricultural Machinery & Equipment.
 Forestry Equipment.
 Oil Field & Offshore.
 Machine Tools and Off- Road Equipment.
 Mining Machinery & Equipment.
 Construction Equipment.
 Suspension in vehicles.

15. • It is a device
used for
producing high
pressure liquid
by using the
energy of
larger amount
of liquid at
low pressure.
HYDRAULIC INTENSIFIER

16. TYPES OF INTENSIFIER
1.Single acting intensifier:
As it supplies high pressure
liquid during downward stroke
only.
2.Double acting intensifier:
It gives continuous supply of
high pressure liquid.

17. • It is required in hydraulic
machines such as hydraulic
presses which requires fluid at
high pressure. And the pump
cannot provide high pressure fluid
therefore a hydraulic intensifier is
placed in between the pump and
machine which would supply high
pressure fluid.
APPLICATION
• Air operated hydraulic intensifier are commonly
used for clamping, holding, punching, presses,
jacks etc.

18. JET PUMP
• A jet pump essentially
comprises a nozzle and a diffuser
assembly.
• Jet pump is used to transfer
momentum from a high
velocity primary stream to a
secondary stream that gets
entrained. It is packaged with
the advantage of geometrical
simplicity without any moving
parts.

19. • Water and air have been used as fluids in the primary and
secondary streams respectively. Nozzle profiles selected is
conical. The mean diameter of nozzles are kept to be 4mm
and 6mm.
• The pressure energy of water converted into kinetic
energy and accordingly the pressure gets reduced.
• A stream of high pressure water from delivery pipe of
the pump or from an independent supply reservoir is
allowed to flow through the nozzle section.
1.in marine applications, jet pumps are used to transfer
seawater.
2.In home applications, they are used to move wastewater up
to the sewer line.
