AIR-AIR PRESSURE MULTIPLIER(BOOSTER)

The air-air pressure multiplier, or booster, is an automaticdevice that compresses air to give an outlet pressure thatis double the inlet pressure.It is normally used to locally intensify the input pressure ofone or more actuators. As it is entirely pneumatic it can beused when electric devices are not recommended.The booster can be supplied with or without a pressureregulator.It is fitted with check valves that maintain the outlet pressureeven when the supply of compressed air is switched off.This means it is necessary to interrupt the supply and relievethe circuit before intervening on the device in any way.It is advisable to install a tank after the booster to preventfluctuations in outlet pressure.

63

The pressure booster is comprised of a central body (with one 3-2valve, one 5-2 valve and four check valves), two side liners and athrough rod on which two pistons are mounted.The supply air is compressed alternately by the two pistons in oneof the two central chambers (B and C); the other central chamberand one of the two side chambers (A and D) operate the pistons;the external chamber, which is not involved in compression, isrelieved.

Air compressed at a ratio of 2:1 passes through a check valve thatmaintains the output pressure even when compressed air is nolonger supplied.The valves in the central body, which are operated by mechanicalpusher pistons, switch the function of the two pairs of chambers (A and D, B and C) at each piston stroke.

TANK FILLING CURVES

The graphs refer to the filling of a 10-litre tank and show the ratio of outlet to inlet pressure (= p2:p1) as a function of time (sec).The graphs are valid for any inlet pressure between 2 and 10 bar.The following formula can be used to calculate the time t (sec) required to switch from pressure ratio 1 to pressure ratio 2 in a tankof volume V (litres):

t = V (t2 – t1) 10

where t1 and t2 are the times shown on the x-axis, corresponding to ratios 1 and 2.

E.g.1 = 0.4 => t1 = 2.5 sec2 = 1.2 => t2 = 10 sec

The time required to switch from 1 to 2 with a 25-litre tank is:

t = 25 (10 –2.5) sec = 18.75 sec 10
