Compressor, accumulator, regulator, valves, and actuator. Of a pneumatic system?

Question

What these are and how they work? Please include details and maybe, if you could, links or pictures/diagrams?

Um, i don't get what your saying Bob... could you explain? And, no i don't have a spraygun system for painting...

Answer 1

A compressor is the air pump which takes air at atmospheric pressure and squeezes it into a smaller volume thereby raising its pressure.

The accumulator in a pneumatic system is also an air receiver which is nothing more than a tank which stores a volumne of air under pressure. The accumulator has a significantly larger volume then the air compressor. As a result as the reciprocating action of the air compressor pumps air into the receiver there is a pulsation in the air supplied into teh receiver. The large volume in the receiver tank helps dampen out the pressure pulsations and serves as a reserve to supply a larger and breif air demand.
The accumulator also provide a means to collect condensate(water) which was pumped in with the air as water vapor. As the air and water vapor cools the water condenses and collects in teh bottom of the accumulator. Periodically the accumulator need to be drained of this condensate.

PLEASE NOT: in hydraulics an accumulator is a little different. Since liquids are in compressable an air bladder is placed inside a tank. liquid entering the tank is pumped in under pressure. this pressure squeezes the bladder and teh air inside it into a smaller volume. If the pump is stopped the the liquid in teh accumulator is still under press becaues the air in the bladder is pushing against the liquid. A common use of accumulators is supplying well water to homes. the well pump switches on and fills teh accumulator with a volume of water then switches off. People use the pressurized sypply of water from the accumulator until such time that the pressure drops to a point where the well pump switches back on. this system keeps the weel pump from short cycling.

A regulator is a type of automatic control valve which opens and closes so as to maintain a set pressure. Regulators are used to reduce the high pressure in teh accumulator and air distribution system into a lower air pressure which is sutable for use.

An actuator is a device which uses air pressure to create a mechanical motion. Actuators are commonly used to operate valves by use of a diaphram connected to the valve stem. Another type isof actuator is a piston inside a cylinder. air is switched from one side of the piston to the other which causes the piston to move. These two types of actuators just mentioned are linear actuators because their action is in a back and forth motion. Rotary actuators will generate a twisting motion. An air operated motor can be used to operate a mechanism

you have a spraygun system for painting. chk "campbell-hausfield", "devilbus" go to any paint store/hardware store/chk ebay,etc
