2. COMPONENTS OF HYDRAULIC SYSTEM
• The major components are:
1. Prime mover
2. Pump
3. Control valves
4. Actuators
5. Piping system
6. fluid

3. COMPONENTS OF HYDRAULIC SYSTEM
• Prime mover:
It is a device which develops the mechanical power. It may
be an IC Engine, electric motor or turbine. The power
developed will be transmitted and utilized. Its type depend
on the type application of system.
• Pump:
Pump is driven by the prime mover, the function of the
pump is to pressurize the fluid thereby converting the
mechanical energy to fluid energy. In case of gas compressor
is used in place of pump.

4. COMPONENTS OF HYDRAULIC SYSTEM
• Control valves:
The pressurized fluid supplied by the pump is required to be
delivered to various parts of the system. The control valves
can be broadly classified into three types:
a) Pressure control valves
b) Flow control valves
c) Direction control valve
• Pressure control valve control and limit the pressure.
• Direction control valve control the direction of the flow by
diverting the fluid to places of use where the fluid is
converted back to mechanical energy.
• Flow control valve controls the flow rate of fluid which in
turn controls the speed of motion of the actuators.

5. COMPONENTS OF HYDRAULIC SYSTEM
• Actuators:
Actuators convert the fluid power contained in
pressurized fluid to mechanical energy. They are the
muscle of the system. They may be of linear or rotary
type, according to desired type of motion.
• Piping system:
It is the vital component of the fluid power system.
They carry fluid containing energy to various parts of
the system. After transferring energy to concerned
part, the return of oil is brought back to the reservoir ,
from where it is re-circulated.

6. COMPONENTS OF HYDRAULIC SYSTEM
• The supporting components are as follows:
a) Filters
b) Heat exchangers
c) Accumulators
d) Measuring gauges
e) Electrical devices
f) Protective devices
g) Sensors
h) strainers

7. COMPONENTS OF HYDRAULIC SYSTEM
• Filters:
Filters are very important for a fluid power system. It is the
filter which works continuously and removes all possible
particulate matter from the oil and keep it in acceptably pure
condition.
• Heat Exchanger:
To limit the temperature of oil which is to be maintained more
or less constant. If the temperature is too high heat can be
released from system. And if temperature is too low of oil it
requires to be increased by applying some heat.
• Accumulators:
Accumulators are storage devices. They provide small pool of
pressurized oil which can be used during emergencies.

8. COMPONENTS OF HYDRAULIC SYSTEM
• Measuring Gauges:
In addition to various functional components, there is a
need to measure certain parameters for monitoring the
proper functioning of the system. For e.g.: pressure
gauges, temperature gauges, etc.
• Electrical Devices:
though fluid power system can operate entirely based
on mechanical controls, electrical devices and control
provide much flexibility in operation. Most of the
electrical devices are used in control of fluid power.
Electrical control enables us the remote operation,
automation and sequencing etc.
