Components of hydraulic system

various components used in hydraulic system..

1. GANDHINAGAR INSTITUTE OF TECHNOLOGY SUBJECT: CONTROL ENGINEERING(2151908) TOPIC: COMPONENTS OF HYDRAULIC SYSTEM. PREPARED BY: JAYDEV PATEL(150120119127) CLASS : 5 C-1 GUIDED BY: PROF. KASHYAP RAMAIYA 1

2. COMPONENTS OF HYDRAULIC SYSTEM The major components are: Prime mover Pump Control valves Actuators Piping system 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: Pressure control valves Flow control valves 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: Filters Heat exchangers Accumulators Measuring gauges Electrical devices Protective devices Sensors 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.
