Pneumatic low density and is compressible at the

Pneumatic systems provide a softer action and are also notable to deliver such large forces. Besides the disadvantages pneumatic systemshave some advantages which are:Simplicity of Design and ControlMachines are easily designed using standard cylinders &other components. Control is as easy as it is simple ON-OFF type control.ReliabilityPneumatic systems tend to have long operating lives andrequire very little maintenance.

Because gas is compressible, the equipment isless likely to be damaged by shock. The gas in pneumatics absorbs excessiveforce, whereas the fluid of hydraulics directly transfers force.StorageCompressed Gas can be stored, allowing the use of machineswhen electrical power is lost.

SafetyVery low chance of fire (compared to hydraulic oil).Machines can be designed to be overload safe.The process of the pneumatic system that is shown above:The compressor receives filtered air form air filter anddelivers through an after-cooler to the compressed air receiver. Then the air is distributed to different applications as wellas the pneumatic cylinder. Pneumatic systems employ gas that iscompressed under extremely high pressure. For some applications where the airmust be perfectly dry, the system also contains a moisture separator. Thepractical use of pneumatics comes in putting that compressed gas to use, at itsmost basic level a pneumatic system holds compressed gas in a speciallydesigned tank and then we release some of that gas into an expandable chamber.The expandable part of the chamber has a rod attached to it so that as it expandsthe rod moves outwardHydraulic actuation systems:Air has a low density and is compressible at the same timeas hydraulic oil has a much higher density and is almost incompressible.

Therefore, hydraulic systems are capable to function at much-advanced pressureand deliver the huge positive forces which are necessary for applications suchas hydraulic presses and lifts. Hydraulic actuation system has advantages whichare listed below:Advantages of hydraulicsLiquid (as a gas is also a ‘fluid’) does not absorb any ofthe supplied energy.Capable of moving much higher loadsand providing much higher forces due to the incompressibility.

The hydraulic working fluid isbasically incompressible, leading to a minimum of spring action. Whenthe hydraulic fluid flow is stopped, the slightest motion of the load releasesthe pressure on the load; there is no need to “bleed off” pressurizedair to release the pressure on the load.The process of the Hydraulic actuation systems that is shownabove:The system has a motor-driven pump which draws filtered oilfrom the tank and distributes it through a pressure regulator to the positionswhere it is necessary. The pump runs constantly and theexcess oil which is not necessary for procedures is diverted back to the tankby the pressure regulator.

It must be noted that the organization generallysupplies a relatively little work area in the locality of the pump and tank.It is not realistic to provide oil under pressure over large distances for thereason that of pressure drop and the need for a return pipe. A manual orautomatic control valve supplies oil to the actuation cylinder and directsreturn oil to the reservoir.A mechanical handling system:The transfer of material, components and assemblies throughthe manufacturing stages often takes a position on roller or belt conveyors.Mechanical handling has a broad variety of handling. Liftinggear used in developing business is broad and in some cases, it is extremelymeticulous.The roller conveyor is most expected the easiest form wheremanufactured goods are passed among workstations along a track having rollers.

Materials are regularly shifted through a motor-driven belts conveyer. Thebelts are from frequently maintained on the concave roller so that falls in thecentre.
