1.FLUID POWER SYSTEM :- Fluid power system is the process of using fluids(oil or water) under pressure to generate, to control, and to transmit power.
2.FLUID POWER SYSTEM:- fluid power system is divided into two types, they are.
1. Hydraulic Fluid Power System
2. Pneumatic Fluid Power System
3. THE FIVE BASIC ELEMENTS IN ANY FLUID POWER SYSTEM ARE :-
1. A Reservoir (or) Tank
2. Pump
3. An Electric Motor
4. Cylinder
5. Valves
4. PURPOSE OF RESERVOIR
The main purpose of reservoir is to store water , to control floods, and to genera hydroelectric power and it is also called as a multipurpose reservoir.
5. The Two Types of Pumps in Compressor are
Centrifugal Pumps
Reciprocating Pumps
6. The Most Common Type of Pump is CENTRIFUGAL PUMPS
7. Audible difference in Compressor
Pumping is a creative misuse of compression, the audible unnatural level changes associated primarily with the release of a compressor.
8. Difference in pump cost
Pump priceses are vary per region and location.
9. Actuator:- An Actuator is a machine which is used to move and control a mechanism or a system.
An Actuator requires a control signal and a source of energy.
10. Linear Actuator :- An example of linear Actuator is Hydraulic Car Jack.
11. Double-Acting – have a port at each end, supplied with hydraulic fluid for both the retraction and extension.
Single-Acting – hydraulic fluid enters through a port at one end of the cylinder, which extends the rod by means of area difference. An external force or gravity returns the piston rod.
13. rotary actuator is an actuator that produces a rotary motion or torque.
The simplest actuator is purely mechanical, where linear motion in one direction gives rise to rotation. The most common actuators though are electrically powered.
14. A valve is a device which regulates, directs or controls the flow of a fluid.
15. The three methods are
1. RIsing stem ball valves
2. Control Valves
3. Gate valves
16. Fluid power is the use of fluids under pressure to generate, control, and transmit power. Fluid power is subdivided into hydraulics using a liquid such as mineral oil or water, and pneumatics using a gas such as air or other gases. Compressed-air and water-pressure systems were once used to transmit power from a central source to industrial users over extended geographic areas; fluid powersystems today are usually within a single building or mobile machine.
