Best Answer

1. Working fluid : Pneumatics use air, Hydraulics use Oil

2. Power : Pneumatic power less than hydraulic power

3. Size : P components are smaller than H components

4. Leakage : Leaks in hydraulics cause fluid to be sticking around the components. In pneumatics air is leaked into the atmosphere.

5. Pneuatics obtain power from an air compressor while hydraulics require a pump

6.Air is compressable, hydraulic oil isn't

Hydraulic oil is slightly compressable particularly when air is entrained within it

Hydraulics can also attain power from an air accumulator

PNEUMATIC POWER IS NOT BNECESSARILY LESS THAN HYDRAULIC POWER

THE LOSSES TEND TO BE GREATER IN PNEUMATICS BUT THIS IS DUE TO ENGINEERING RATHER THAN CHARACTERISTICS.

Pneumatics are much easier to configure for control applications

I disagree with answer 3 above, it depends on the application.XD

Pneumatic machines use the power of compressed air to perform work.

Hydraulic machines use the incompressibility of water under pressure to perform work.

Depends entirely on what you're doing.

If it's light weight work - Doors and the likes, pneumatics.

If it's heavy duty work - JCB and construction, hydraulics.

No. Pneumatic refers to air whereas hydraulic refers to water or other liquids. The behaviour of pneumatics and hydraulics differs because air is more compressible than liquids.

The main difference between pneumatic cylinders and hydraulic cylinders is that hydraulic cylinders?

Hydraulic cylinder use a liquid medium, often some type of viscous oil, in the cylinders and can be subject to higher pressures then pneumatic cylinders which use air or some other gas and work under a lower pressure.


How the correlation between hydraulic motor and hydraulic pump?

Internally, they're pretty much the same. The difference is the operation expected of it - a hydraulic pump converts mechanical energy to fluid energy, whereas a hydraulic motor converts hydraulic energy to mechanical energy.


How can you tell the difference between a hydraulic lifter and a mechanical lifter on a Chevy 350 engine?

Take a pushrod and push down on the plunger in the lifter. A hydraulic lifter is spring loaded.


What is the difference between a hydrostatic and a hydraulic system?

By "Hydrostatic" systems one tends to mean "closed loop hydraulic systems". That is hydraulic systems comprising a pump and motor hwere the pump supplies the motor whose return side supplies the pump. The speed and direction of rotation of the hydraulic motor being changed according to the displacement angle of the variable displacement axial pison pump. "Open loop hydraulic systems" on the other hand comprises various motors often one or more "linear motors" (hydraulic cylinders). When using hydraulic cylinders in hydraulic systems one needs a reservoir to be able to hold the various volume need of the cylinder. (the displacement on the piston side is usually bigger than the rodside). The reservoir needs a "breather" due to the varous displacement needs hence the "open system".


What is the difference between hydrolics and pneumatic?

Hydraulic cylinders will be linked to the bath at both ends, as the oil needs to remain pressurised to work effectively.Pneumatic cylinders have springs if they're single way cylinders, as generally they can't rely on gravity to revert back to the first stage - dual cylinders on the other hand have 2 springs so they can switch sides.That aside, the hissing from Pneumatics should just about give it away.

What is the Difference between pneumatic cylinders and hydraulic cylinders is?

Working fluid. In one it's gas (air) and in the other it's liquid. This is a much bigger difference than it might seem at first, because gases are compressible and liquids, to a very good approximation, are not.

Difference between hydraulics and pneumatics?

hydraulic is liquid based, pneumatic is air.


What is the difference of pressure between pneumatic and hidraulic?

Any pressure difference is irrelevant. The distinction is in the operating fluid. In pneumatic systems, it's a gas. In hydraulic systems, it's a liquid.


What is the difference between pneumatic elevator and hydraulic elevator?

Pneumatic elevators work on air pressure (similar to a bank's drive through suction tubes) and hydraulic elevators work on oil/water pressure.

What is the difference between hydraulic and pneumatic symbols?

It all comes under Fluid dynamics/mechanics, and it's the same set of symbols for circuits. Many hydraulic symbols will include a drain to the tank. Pneumatic circuits use the atmosphere as their "tank".


What's the difference in performance between a pneumatic and a hydraulic rotary actuator?

Hydrolic are faster and more powerful. They use comressed air.

How are pneumatic and hydraulic systems different?

the main difference between hydraulic and pneumatic system is that hydraulics uses fluid to power their system and pneumatic uses air (in that case air is not a fluid) All matter is made up with all particles. thanks you can see more answer in this web i put these all answer.


What is the difference between a valve and actuator?

actuator is a mechanism that will responds to hydraulic,pneumatic and electrical signal ,it is used to control the valve that to be in open or close condition.


Difference between Pneumatic and hydraulic test?

There are many differences, and here are a few: Pneumatic systems use gasses which are compressable - hydraulic uses liquids that are non-compressable. Hydraulics' motion is slow and smooth - pneumatics' motion is quick. Pressure can range from 500 to 5000 psi - pneumatics operate at around 100 psi.
